In this engaging episode of the HVAC School podcast, host Bryan Orr sits down with Leo and Paul Sharkey, a father-son duo of mechanical engineers who made the leap into the HVAC business. Leo and Paul share their remarkable journey of purchasing an HVAC company in September 2020 and quadrupling its revenue within five years. Their engineering backgrounds bring a refreshing, data-driven perspective to an industry that often relies on rules of thumb and outdated practices. The Sharkeys operate in the challenging Northeast market, where homes can date back to the 1600s and 1700s. They discuss the eye-opening discovery that traditional HVAC sizing methods—like the simplistic "one ton per 400 square feet" rule—fail dramatically in older housing stock. Their commitment to running thousands of Manual J calculations has transformed their approach, often resulting in smaller, more efficient systems than competitors propose. The conversation dives deep into the unique challenges of working with centuries-old New England homes, including extreme infiltration rates, non-linear heat loss curves during harsh winters, and the complications of mixing modern additions with ancient construction. Beyond sizing, Leo and Paul tackle the practical realities of heat pump installations in cold climates. They explain why turndown ratio is critical, how they handle homes with heat loads that triple their cooling loads, and when backup heating systems are truly necessary. Their consultative approach rejects the "one-size-fits-all" mentality that has flooded the market with incentive-chasing installations. They candidly discuss the problems created by Massachusetts' generous rebate programs, which have attracted fly-by-night operators who prioritize rebate qualifications over proper design and long-term performance. The episode also explores the balance between ductless and ducted systems, revealing when each approach makes economic and technical sense. The Sharkeys share fascinating case studies, from a 1748 house with the equivalent of a full-size door's worth of air leakage to underground concrete dome homes requiring specialized dehumidification. Their willingness to take on complex projects that other contractors avoid demonstrates how engineering thinking, combined with trade expertise, can solve challenging HVAC problems. This conversation is essential listening for anyone serious about understanding cold climate HVAC design, building science principles, and what it takes to deliver quality comfort solutions in real-world conditions.

In this essential episode, Bryan Orr sits down with Elliot, the residential install supervisor at Kalos Services, to unpack a critical issue that's causing confusion among HVAC technicians, electricians, and inspectors alike: the new standards for breaker and conductor sizing on inverter-driven equipment. The conversation was sparked by Elliot's frustrating experience of having two inspectors in the same county fail the same installation for opposite reasons—one for an oversized breaker and another for an undersized breaker. This contradiction led to a deep dive into recent changes in UL standards and how they affect everyday HVAC installations. The heart of the issue stems from the transition to low-GWP refrigerants and the updated UL 60335-2-40 Edition 3 standard, which replaced the 1995 certification approach. This new standard introduced more conservative calculations for electrical characteristics, particularly affecting equipment using A2L refrigerants. The result? Data tags now show higher Minimum Circuit Ampacity (MCA) ratings than before, even though the equipment itself hasn't changed—only the math used to calculate these values has shifted. This has created a puzzling situation where the MCA can be higher than the recommended breaker size, which seems counterintuitive to anyone familiar with traditional electrical principles. Bryan and Elliot clarify the fundamental rule that still applies: size your wire to the MCA and your breaker to the MOCP (Maximum Overcurrent Protector). The confusion arises because manufacturers like Mitsubishi are now including "recommended breaker" sizes on data tags that are lower than the MCA—a courtesy to contractors, not a code requirement. The higher MCA reflects conservative safety margins that account for extreme operating conditions, but in practice, inverter-driven systems have multiple built-in protections that prevent them from ever actually reaching these calculated amperage levels. The key takeaway is that contractors can safely install breakers at the recommended size without safety concerns, as long as the breaker's lugs are rated to accept the wire size required by the MCA. The episode also explores how inverter-driven equipment fundamentally differs from traditional PSC motors, particularly regarding locked rotor amps (now more accurately termed "inverter input") and voltage drop considerations. Unlike conventional motors that simply run slower with reduced voltage, inverter-driven compressors and ECM motors compensate by drawing more current to maintain performance, creating a potential compounding effect with voltage drop that installers need to understand—even though voltage drop itself isn't an enforceable NEC code requirement. Topics Covered: New UL 60335-2-40 Edition 3 standards and their impact on electrical calculations for HVAC equipment The relationship between MCA (Minimum Circuit Ampacity) and MOCP (Maximum Overcurrent Protector) and why they can now seem contradictory Recommended breaker sizes on modern data tags and why they may be lower than the MCA Handling inspector conflicts and failed inspections related to breaker sizing Differences between inverter-driven equipment and traditional PSC motors in electrical behavior The transition from "locked rotor amps" to "inverter input" terminology for modern equipment Voltage drop considerations with inverter-driven systems (NEC 210.19A and 215.2A) Why inverter-driven equipment draws more current at lower voltages compared to traditional motors Proper wire and breaker sizing for A2L refrigerant equipment (454B systems) NEC Section 440 requirements specific to air conditioning and refrigeration equipment Breaker lug ratings and ensuring they can accept the required wire size Practical advice for communicating with inspectors and resolving code disputes Read the tech tip on this topic HERE.

In this comprehensive episode of the HVAC School podcast, host Bryan Orr sits down with three experts from Copeland to demystify tandem and trio compressor systems. Joining him are Gina Kahle (Multiples Engineering Manager with 12+ years at Copeland), Tyler Daniels (Product Management team member), and James Stevenson (Technical Sales veteran with 28 years of field experience). Together, they provide both the engineering perspective and real-world service insights that technicians need to understand these increasingly common systems. The conversation begins with the fundamentals: tandem and trio systems represent an evolution in compression modulation, allowing multiple compressors to work together on a single circuit rather than requiring separate circuits for each compressor. This design philosophy delivers significant advantages, including energy savings through better modulation, simplified system design, reduced costs, and the ability to meet stringent minimum modulation requirements (such as the 25% threshold for units under 60,000 BTUs per hour). The team emphasizes that tandems aren't just about pairing any two compressors together—Copeland engineers carefully consider application requirements, flow characteristics, and stress testing to ensure reliable oil management and system resonance control. A major focus of the discussion centers on practical service considerations that every technician needs to understand. James provides invaluable guidance on identifying whether a failed compressor in a tandem system can be replaced individually or requires replacing the entire tandem assembly. The "rule of thumb" is clear: compressors small enough to fit in residential systems (typically under 10 horsepower or about 7 inches in diameter) generally require full tandem replacement, while larger units may allow single compressor replacement. The distinction between "tandem ready" and non-tandem ready compressors becomes critical here—larger compressors (10+ horsepower) are typically sold tandem ready at wholesalers with the necessary oil equalization ports and sight glass connections, while smaller units are not. The episode also explores advanced topics, including the integration of Enhanced Vapor Injection (EVI) technology with tandem systems, particularly for cold climate heat pump applications. Gina explains how EVI extends the operating envelope down to -40°F, opening new markets and applications. The team discusses the transition to A2L refrigerants and how Copeland continues to innovate despite changing regulatory landscapes. Throughout the conversation, they emphasize the critical importance of proper oil management through oil equalization lines (OEL) and two-phase transfer lines (TPTL), and why maintaining these connections exactly as designed is non-negotiable for system longevity. Key Topics Covered: Tandem and Trio Basics: Definition and benefits, including energy savings, cost reduction, and design simplification Modulation Requirements: Meeting state-mandated minimum modulation thresholds (25% for units under 60,000 BTU/hr) Applications: Data centers, DOAS units, rooftops, chillers, and various commercial spaces Compressor Pairing Options: Fixed speed, digital, variable speed, two-stage, and mixed configurations Oil Management: Critical importance of oil equalization lines (OEL), two-phase transfer lines (TPTL), and gas equalization lines (GEL) Service and Replacement: How to identify tandem-ready vs. non-tandem-ready compressors; when to replace individual compressors vs. full tandem assemblies Visual Identification: Using compressor size (7" vs 9" diameter), port configuration, and horsepower ratings to determine replacement strategy Piping Configurations: Three-pipe vs. four-pipe designs and when each is necessary Installation Considerations: Importance of keeping oil equalization lines level (parallel to ground) and using proper mounting spacers Enhanced Vapor Injection (EVI): How EVI technology extends operating envelopes to -40°F for cold climate heat pump applications Energy Efficiency Standards: Meeting IEER, IPLV, and upcoming IVEC standards through strategic tandem use Copeland Mobile App: Features, including parts lookup, resistance specifications, amperage mapping, AI Scout assistant, and technical bulletins Learn about the Copeland Mobile app at https://www.copeland.com/en-us/tools-resources/mobile-apps/copeland-mobile.

In this episode of the HVAC School podcast, Bryan Orr sits down with Bert and Leanna to discuss Kalos's first official cohort apprenticeship program, dubbed the "Launch Program." What started as Bryan's persistent idea—one that the team initially resisted as too expensive and logistically challenging—evolved into a transformative three-month training experience that brought 15 green apprentices through intensive classroom, lab, and field work across HVAC, electrical, and building automation systems. Bert, who graded himself a B for his first attempt at leading the program, shares candid insights about the challenges of planning and execution. While he meticulously mapped out the first two weeks hour-by-hour, the remaining time was far less structured, leading to valuable lessons about the importance of ongoing planning and verification. Leanna, who came to Kalos with both teaching experience and a commercial HVAC background, brought crucial support that Bert initially didn't think he needed. Her contribution proved essential in managing the group of 15 and ensuring hands-on engagement. Of the original cohort, nine graduated, with two additional apprentices added later who showed exceptional promise. The conversation reveals critical insights about what makes training effective in the trades. Both trainers emphasize the importance of hands-on experience over lecture, with Bert noting his biggest mistake was spending an entire day lecturing on refrigerant circuits before showing apprentices actual equipment. The most successful exercises involved real-world scenarios, like Leanna's mock dispatch day where apprentices handled service calls from start to finish, including customer communication. The program also incorporated broader trade skills beyond HVAC—carpentry, ladder safety, and tool confidence—recognizing that many young workers today lack the tactile experience that builds confidence in using tools and solving problems independently. Perhaps most importantly, the discussion highlights the value of verification and confidence-building over knowledge dumping. Bert learned that making diagnostic exercises too complex early on destroyed apprentice confidence, while starting simple and building up created self-motivated learners. The cohort model's unique advantage lies in its competitive yet supportive environment, where apprentices can gauge their progress against peers who started at the same level, creating natural motivation to improve. While expensive and demanding, the program represents a long-term commitment to developing well-rounded tradespeople who can think critically and solve problems—not just perform repetitive tasks. Topics Covered: The origins and initial resistance to implementing a cohort-style apprenticeship program Structuring a 90-day training program with classroom, lab, and field components The critical importance of planning and having adequate instructor support Selecting apprentices: key traits including self-motivation, adaptability, and humility Balancing lecture, hands-on training, and real-world field experience The power of verification and skills checklists over pure knowledge transfer Teaching broader trade skills (carpentry, ladder work) to build overall confidence Creating realistic scenarios like mock service calls for soft skills development Managing group size and the challenges of keeping all apprentices engaged The role of confidence-building in safety and long-term success Starting simple with diagnostic exercises and building complexity gradually Using field feedback and peer comparison as motivational tools The cost and commitment required to run effective cohort training programs Have a question that you want us to answer on the podcast?

In this candid conversation recorded live at the NCI Summit in Austin, Bryan Orr sits down with Chad Simpson, owner of Simpson Solutions, for an unexpectedly revealing discussion about the reality of building a successful HVAC business. What makes this episode particularly compelling is Simpson's refreshing honesty about his struggles, failures, and the gradual transformation from a struggling contractor making $8 an hour to running a $28.5 million operation with healthy profit margins. Simpson's journey began unusually early—he wrote a paper in his freshman year of high school (1996) declaring his intention to own an HVAC company. After graduating from trade school and working for a residential replacement contractor, he started his own business with his father, who had just retired from building interstates and bridges. For the first eight years, Simpson made virtually no money despite working 12-hour days, falling into the common trap of thinking he could "outrun" financial problems by simply working harder and hiring more people. The turning point came around 2008 when mentor Brad Hohn discovered Simpson calling receivables on a golf course to make payroll—and offered to help departmentalize his finances with the promise of a Vegas golf trip once Simpson hit 10% net profit. The most striking aspect of Simpson's story is his emphasis on process documentation and his willingness to admit what he didn't know. After finally achieving profitability, he hired a business coach who refused to write processes for him, insisting Simpson had to "own" them himself. This led to the creation of Simpson's now-famous process book, which started with simple one-page job descriptions and grew to encompass every aspect of the business. Simpson's approach to callbacks changed dramatically after 2021, when his company's callback rate hit 23% following rapid growth. Working with Jim Bergmann and implementing Measure Quick transformed his operation from quick-fix service calls to thorough 2.5-3 hour diagnostics that actually prevent future problems rather than creating false urgency. Perhaps most impressive is Simpson's Fast Track training lab, which he built initially just to train his own technicians but has evolved into a resource for competitors, universities, and the entire industry. His philosophy centers on finding real problems through proper diagnostics rather than making up issues or pushing unnecessary replacements. Simpson emphasizes that service technicians should educate, not sell—and that when you deploy the right tools and probes, you'll find plenty of legitimate problems without resorting to dishonest tactics. Today, Simpson's company maintains a 2% service callback rate and 3% install callback rate while continuing to grow and expand into plumbing services. Topics Covered: Starting an HVAC business straight out of high school with minimal capital and business knowledge The reality of struggling financially for the first eight years despite long hours and hard work The critical importance of understanding financial KPIs and departmentalized accounting How mentorship from Brad Hohn transformed Simpson's approach to business financials Building comprehensive process documentation and job descriptions for every role The difference between being teachable versus being controlling as a business owner Transitioning from quick-fix service calls to thorough diagnostic work using Measure Quick and True Flow tools Reducing callback rates from 23% to 2-3% through proper commissioning and diagnostics Creating the Fast Track training lab and training competitors at no cost The philosophy of finding real problems versus creating false urgency with customers Why service technicians should focus on education rather than sales tactics Scaling from $3.5 million to $28.5 million while maintaining healthy profit margins Expanding into plumbing services using the same process-driven approach developed for HVAC The importance of celebrating wins as a team and taking responsibility for losses as a leader News for next year's High-Performance HVAC Summit will be available at gotosummit.com.

In this comprehensive episode, Bryan Orr sits down with Tim De Stasio to explore the world of comfort consulting and performance contracting in HVAC. Tim, who sold his contracting company to focus on this specialized field, shares his methodical approach to diagnosing home performance issues that go far beyond traditional HVAC troubleshooting. Working primarily in the humid coastal North Carolina market, Tim has developed a thorough process that treats the house as a complete system rather than just focusing on equipment. Tim's journey into comfort consulting began when he recognized the value of comprehensive home performance testing after seeing the work of practitioners like Michael Housh. His approach combines ethical selling with rigorous testing and data collection, allowing him to stand behind his recommendations with confidence. Unlike traditional HVAC service calls that might only involve checking refrigerant levels, Tim's comfort consultations can take an entire day and involve extensive testing protocols that examine everything from building pressure to thermal imaging. The conversation reveals how this type of work requires a fundamental shift in thinking - from being an equipment-focused technician to becoming more like a field engineer or building scientist. Tim emphasizes the importance of having repeatable processes and comprehensive checklists, using tools like Safety Culture app to document findings with photos, notes, and annotations. His methodology starts with a detailed pre-visit questionnaire and includes preparing clients for what will be a very different experience from typical HVAC service calls. Perhaps most importantly, Tim demonstrates how proper diagnostics can lead to ethical sales opportunities. By using tools like blower door tests, thermal imaging, building pressure measurements, and comprehensive system evaluations, he can provide clients with data-driven recommendations prioritized by impact and return on investment. His approach includes a two-week period for analysis before delivering final recommendations, ensuring thoughtful conclusions rather than rushed judgments. Topics Covered The Business Model of Comfort Consulting - How Tim structures his three-pronged business: home performance testing/comfort consultations, HVAC design for contractors, and training Preparing Clients for the Process - Using pre-visit questionnaires, YouTube videos, and setting proper expectations for an all-day, disruptive home evaluation Comprehensive Visual Assessment - The "hands in pockets" approach, starting with exterior building examination including gutters, downspouts, vent terminations, and moisture issues Interior Documentation Process - Room-by-room photo documentation, thermal imaging for missing insulation and thermal bridging, and moisture meter readings Crawl Space and Attic Inspections - What to look for in foundation issues, vapor barriers, insulation conditions, and air sealing problems Ventilation System Testing - Using flow boxes to measure bathroom fan performance, checking kitchen exhaust, and verifying dryer connections Building Pressure Testing Protocols - Stack effect measurements, worst-case depressurization testing, dominant duct leakage assessment, and building pressure balance testing Blower Door Testing Procedures - Proper setup, safety considerations, CFM50 vs ACH50 measurements, and using results for Manual J calculations Thermal Imaging During Depressurization - Advanced techniques for identifying air leakage paths and problem areas throughout the building envelope HVAC System Performance Analysis - Using Measure Quick for comprehensive system evaluation, comparing load calculations to nameplate capacity and delivered performance Indoor Air Quality Monitoring - Integration of Haven Central monitors for long-term data collection and analysis Report Generation and Client Communication - Creating field reports vs. final reports, prioritizing recommendations by impact and ROI Testing Out and Verification - The importance of return visits to quantify improvements and validate work performed Have a question that you want us to answer on the podcast?

In this insightful episode of the HVAC School podcast, Bryan Orr sits down with successful small business owner Matt Bruner to discuss how to build and maintain a thriving HVAC business without the typical stress and overwhelming challenges that many entrepreneurs face. Matt, who has been running his own HVAC company for about two and a half years, shares his refreshingly honest perspective on small business ownership and debunks many of the common myths about entrepreneurial stress. Matt's journey from technician to business owner offers a compelling alternative to the traditional "grow fast or fail" mentality that pervades much of the business world. His approach centers on building a business aligned with personal values, particularly the desire to maintain work-life balance while still delivering excellent technical service. Rather than focusing on rapid expansion, fancy equipment, or impressive marketing, Matt chose to start lean, borrow minimal money (only $10,000 from his father for a van down payment), and grow organically while keeping overhead low and stress manageable. The conversation delves deep into the financial discipline required for successful business ownership, emphasizing the critical importance of separating personal and business finances, understanding your true hourly costs, and charging appropriately from day one. Matt candidly discusses his learning curve with business finances, from initially relying on advice from online communities to eventually working with a business coach and reading key books like "Profit First" to truly understand the numbers behind his operation. Both hosts stress that financial literacy isn't optional for business owners—it's a learnable skill that requires dedication but isn't as intimidating as many people believe. Throughout the discussion, both Bryan and Matt emphasize that there's no single "right" way to build a successful contracting business. While some entrepreneurs thrive on rapid growth, multiple locations, and eventual private equity buyouts, others find fulfillment in staying small, maintaining direct customer relationships, and focusing on technical excellence. The key is knowing yourself, understanding your values, and building a business structure that supports your personal and professional goals rather than chasing someone else's definition of success. Topics Covered Personality traits that support successful small business ownership - The importance of being naturally critical, curious, and willing to take control of your destiny Financial discipline and money management - Separating personal and business finances, understanding billable hours vs. total work time, and charging appropriately from the start Starting lean and avoiding debt - Matt's approach of borrowing minimal money, using magnets instead of van wraps, and subcontracting initially to build capital The learning curve of business finances - Books and resources that helped Matt understand accounting basics, profit margins, and business financial planning Work-life balance in business ownership - How to build a business that serves your lifestyle goals rather than consuming your entire life Choosing your business model - The difference between lifestyle businesses and growth-focused companies, and why both approaches can be successful Technical work vs. business management - Balancing hands-on HVAC work with administrative tasks and knowing when to delegate or systematize Pricing strategies and customer relationships - How proper pricing from the beginning actually reduces customer complaints and builds a sustainable business model Common mistakes to avoid - Poor financial decisions, mixing personal and business expenses, undercharging, and chasing other people's business models Building systems and staying organized - Using checklists, scheduling business development time, and creating processes to prevent important tasks from falling through the cracks Partnership considerations - The challenges and benefits of starting a business with partners or family members versus going solo Long-term sustainability - How to avoid burnout, maintain quality standards, and build a business you can operate for decades Have a question that you want us to answer on the podcast?

Building HVAC Science - Building Performance, Science, Health & Comfort
In this episode of the Building HVAC Science Podcast, hosts Bill Spohn and Eric Kaiser sit down with two passionate leaders from the GRIT Foundation—Executive Director Leilani Orr and Head of Training Ty Branaman. Together, they unpack the origin story, purpose, and transformative impact of GRIT Camps, which introduce youth to the skilled trades in immersive, hands-on ways. The conversation explores how GRIT—which stands for Growth and Resilience in the Trades—isn't just a clever acronym but a mindset. Through personal stories, Leilani and Ty reflect on the deeper "why" behind the camps: fostering curiosity, building confidence, and instilling pride in practical skills that often go unrecognized. They discuss how using tools like the Socratic method not only helps students learn but transforms mentors as well—often reigniting their passion for the trades. You'll hear about real-life transformations: timid students who become torch-wielding creators, mentors discovering new ways to engage, and parents witnessing their children light up with newfound purpose. As a pending nonprofit, the GRIT Foundation is fueled by heart, vision, and a small but mighty network of supporters—with hopes of expanding nationwide through thoughtful partnerships. “If I can do this, anybody can do this. I don't want to be the guy—I want to be the guy helping other people become the guy.” – Ty Branaman “We're not recruiting kids into the trades—we're fostering curiosity and confidence in whoever they want to become.” – Leilani Orr “What you're doing is important because it touches your heart—or brings a tear to your eye.” – Bill Spohn The Grit Foundation: https://www.thegritfoundation.com/ Leilani's LinkedIn: https://www.linkedin.com/in/leilani-orr-5a0948343/ Ty's LinkedIn: https://www.linkedin.com/in/ty-branaman-cmhe-07604a33/ Bryan Orr's book, Unconfomed: An Unbound and Unbridled Path to Unstuck Growth: https://a.co/d/9zMmSmQ This episode was recorded in July 2025.
In this episode of the HVAC School podcast, Bryan Orr sits down with Adam and Matt to tackle one of the most misunderstood aspects of HVAC system design: return air systems. The conversation dives deep into the common myths surrounding returns, particularly the widespread belief that adding returns to rooms will automatically improve comfort and air mixing. The hosts explore why returns are often seen as mysterious - sometimes helping when added to a room, sometimes making things worse - and work to clarify the actual science behind how returns function versus how many technicians think they work. The discussion reveals a fundamental misunderstanding in the industry about the difference between supply and return air behavior. While supply air creates significant mixing effects through entrainment and the Coanda effect, returns have a much more limited impact on room air patterns. According to Manual T, laboratory tests show that return air intake influence is limited to just a few feet around the grille, even at high velocities. This leads to the key insight that returns serve primarily as pressure relief mechanisms rather than air mixing devices, which explains why their placement and sizing strategies differ significantly from supply air design principles. The hosts examine real-world scenarios, including Matt's experience with a two-story home where the homeowner requested an additional return on the second floor despite having adequate return pathways. They discuss the Manual D recommendation for returns on each floor while sharing field experiences where single central returns have successfully maintained temperature differentials within two degrees across multiple floors. The conversation emphasizes that proper system design, including accurate load calculations and right-sized equipment, often eliminates the need for complex return strategies. A significant portion of the discussion focuses on the practical considerations of passive versus active returns. The hosts lean toward passive return strategies (transfer grilles, jumper ducts, and door undercuts) for their simplicity, cost-effectiveness, and reduced ductwork requirements. However, they acknowledge the challenges of proper sizing - passive returns must be significantly larger than their active counterparts since they rely on minimal pressure differentials rather than mechanical assistance. The conversation also addresses privacy concerns with transfer grilles and the benefits of oversized jumper ducts for noise attenuation. Key Topics Covered Common Return Myths Debunked The belief that adding returns automatically improves room comfort Misconceptions about returns mixing air effectively The difference between supply air entrainment and return air influence Pressure Relief vs. Air Mixing Returns function primarily for pressure balancing, not air circulation How to measure pressure problems using flow hoods and micromanometers The impact of door closure on supply air delivery Manual D Guidelines and Field Reality Manual D recommendations for returns on each floor Real-world examples of successful single central return systems When to follow guidelines versus when field conditions allow flexibility Passive Return Strategies Transfer grilles, jumper ducts, and door undercuts as alternatives to active returns Proper sizing considerations for low-resistance return pathways Privacy and noise concerns with different passive return methods System Design Fundamentals The importance of accurate load calculations in reducing return requirements How right-sizing equipment reduces airflow and pressure management challenges The relationship between static pressure and airflow changes Zoning Considerations Whether to add dampers to returns in zoned systems Potential depressurization issues when zones are closed Passive solutions for zoned system return air management Practical Installation Tips Avoiding short-cycling by maintaining proper supply-to-return distances The risks of undersized return pathways Balancing damper selection and sealing strategies Advanced Concepts Destratification strategies using ceiling fans versus high returns The impact of conditioned versus unconditioned return air pathways Energy efficiency considerations in return system design Have a question that you want us to answer on the podcast?

In this episode of the HVAC School podcast, Bryan Orr sits down with Roman Baugh, a leading VRF (Variable Refrigerant Flow) specialist and co-host of the VRF Tech Talk podcast, for an in-depth exploration of VRF system maintenance. The conversation begins with some lighthearted back-and-forth before shifting to the technical realities of maintaining VRF equipment. Roman immediately addresses a common misconception: the idea that VRF systems are “maintenance free.” He explains that, contrary to some marketing claims, these systems require regular, specialized attention to ensure longevity and reliable performance. Roman shares real-world stories that highlight the consequences of poor installation and lack of serviceability. He describes situations where VRF units are installed in hard-to-reach locations—like cabinets or hard-lid ceilings—making even basic maintenance a costly and invasive process. This lack of foresight often leads to significant expenses for property owners, especially when major repairs require extensive drywall work just to access failed components. Roman emphasizes that proper maintenance starts with ensuring that systems are accessible and serviceable, a step too often neglected during installation. The discussion delves into the specifics of VRF maintenance, moving beyond the basics of filters and drain lines. Roman explains how improper drain line installation can lead to persistent error codes and system shutdowns, particularly when condensate pumps are forced to exceed their design limitations. He goes on to detail the critical role of temperature sensors (thermistors), which are prone to failure from corrosion, moisture, and environmental factors—especially in challenging locations like laundry rooms. These sensor failures can cause misleading error codes and even compressor damage if not addressed promptly. Roman recommends regular sensor checks, especially as components age past their typical five-year lifespan. A significant portion of the episode is dedicated to electronic expansion valves (EEVs), which are susceptible to rust, dried grease, and mechanical binding. Roman advocates for proactive inspection and, when necessary, preemptive replacement of EEVs to prevent catastrophic compressor failures. He introduces tools developed by technicians for technicians, such as the EEV Mate and custom EEV magnets, which allow for manual manipulation and diagnostics of expansion valves in the field. These innovations help HVAC professionals quickly triage and resolve issues, minimizing downtime and protecting expensive system components. The episode wraps up with a strong endorsement for ongoing education, technician communities, and the use of specialized tools and software to ensure VRF systems are maintained to the highest standard. Topics Covered: Debunking the “maintenance-free” VRF myth Access and serviceability challenges in VRF installations Proper drain line design, installation, and common failure points The role and failure modes of temperature sensors (thermistors) Environmental impacts on sensor and component reliability Electronic expansion valve (EEV) maintenance and troubleshooting Field-developed tools for EEV diagnostics (EEV Mate, EEV magnets) The importance of commissioning and using service software Application and installation quality as a foundation for long-term reliability Technician communities, podcasts, and resources for VRF learning and support This episode is essential listening for HVAC professionals seeking to deepen their understanding of VRF systems, avoid common pitfalls, and stay ahead with practical, field-tested maintenance strategies.

Bryan Orr and Steve Rogers dive deep into measuring power consumption in HVAC blower motors, particularly focusing on the differences between PSC (Permanent Split Capacitor) and ECM (Electronically Commutated Motor) technologies. The discussion stems from a question raised at an educators' conference about the accuracy of clamp-on meters in measuring blower motor watt draw, as specified in the ACCA Standard 310. Steve shares insights from extensive testing conducted with different types of motors and power meters. The tests compared PSC motors with constant torque and constant airflow ECM motors across various static pressure conditions. One key finding was that two out of three field-available clamp-on meters tested were capable of accurately measuring true power at levels expected in residential blower motors. However, one meter showed significant inaccuracy at low power levels, highlighting the importance of carefully reviewing meter specifications before use. The conversation delves into the concept of power factor and its crucial role in understanding the true power consumption of ECM motors. Steve explains that ECM motors often have a low power factor (around 0.6), which can lead to misconceptions about their efficiency if only the current draw is measured. The discussion emphasizes the need for proper measurement techniques, including simultaneous voltage and current readings with the blower door on, to accurately assess motor efficiency. Key topics covered in the podcast: Differences between PSC and ECM motor technologies Importance of power factor in measuring true power consumption Accuracy of field-available clamp-on meters for power measurement Impact of static pressure on motor performance and efficiency Misconceptions about ECM motor efficiency and longevity Proper measurement techniques for assessing blower motor watt draw Relationship between duct system design and motor efficiency Implications of ACCA Standard 310 for HVAC installations Challenges in comparing constant torque and constant airflow ECM motors The role of control algorithms in ECM motor performance Importance of understanding meter specifications for accurate measurements Have a question that you want us to answer on the podcast?

Throughout the conversation, Bryan and Pam touch on workforce development topics related to peer and parent pressure towards traditional college, the need to lift up skilled trades, and the importance of following your interests even if they start as hobbies.
In this HVAC podcast episode, hosts Bryan Orr and Matthew Taylor (refrigeration leader and trainer at Kalos Services) discuss oil management and considerations in supermarket refrigeration systems, with a focus on solving & preventing oil issues. They talk about the importance of stable system operation and how oil flows through both active and passive systems in these larger built-up racks. Matthew explains that in a rack system, oil is actively separated and returned to the compressors through a dedicated system. However, not all oil gets captured this way, so the passive system of oil returning through the refrigeration cycle still occurs. Problems can arise in either system, leading to compressors locking out. Matthew stresses properly setting and regulating EPR valves to minimize load fluctuations that impact system stability. Common issues covered include clogged oil separators, misadjusted or damaged oil controls, changes in suction pressure affecting oil flow, the impact of floating suction pressures, and troubleshooting overfilled compressors. Matthew offers tips like feeling the oil separator line temperature and using working racks as a guide when unsure of proper settings. The discussion highlights how poor defrost performance can indicate oil trapping issues. Matthew and Bryan also cover: Active vs passive oil management in racks Setting EPR valves for stable operation Clogged oil separators and failed floats Suction pressure fluctuations disrupting oil flow Strategies for floating suction pressures Steps for readjusting oil controls Signs of oil trapping issues in the refrigeration cycle Using working racks to guide troubleshooting Learn more about the 5th Annual HVACR Training Symposium at https://hvacrschool.com/Symposium24.

In this episode of HVAC School, hosts Bryan Orr and Bert discuss practical tips for preventing callbacks and failed inspections in residential HVAC installs and maintenance. Bryan and Bert stress the importance of getting the basics right, like properly cleaning condensate drains, ensuring proper drain pitch, and sealing ducts completely before relying on tapes and mastic to cover gaps. They emphasize verifying full system operation at the end of a job, from checking that drains flow freely to testing float switches and pressure testing for leaks. Bryan and Bert also cover wire and breaker sizing for equipment changes, securing disconnects, proper thermostat wall seals, inspecting joints with bubbles to find microscopic leaks, and more thorough evacuations and leak checks. Throughout the casual, conversational show, the hosts inject colorful commentary on doing quality work with a little sarcasm, including praising the merits of duct board and flex ducts. The tone is partly tongue-in-cheek but drives home the point that shortcuts lead to callbacks and leave clients dissatisfied. Bert and Bryan also discuss: Becoming masters of the obvious Common condensate line issues The issues with double traps Ensuring adequate filter access for the customer Wiring float switches in series vs. in parallel Sealing ductwork effectively Using your senses to find airflow leaks in the ductwork Pressure testing for refrigerant leaks Common leak points in systems and their causes Correct electrical setup and markings Securing outdoor unit placement Sealing thermostat wall penetrations Thorough evacuation and leak checks Learn more about the 5th Annual HVACR Training Symposium at https://hvacrschool.com/Symposium24.

In this podcast, Bryan Orr and Bert discuss various aspects of pool heaters, focusing on issues that make them different from typical HVAC systems. They cover the basics of pool heaters - the main types (heat pumps and gas heaters) and how they operate similarly or differently from things HVAC techs work on regularly. The bulk of the 45-minute podcast looks at common service and troubleshooting situations with pool heaters, which are usually installed by pool contractors initially and not HVAC contractors. Bryan and Bert talk through typical causes of common error codes and problems like units frequently going out on high pressure. They cover water flow issues and the role of pressure versus flow switches, the sizing and limitations of heat pumps, low ambient operation challenges, freeze protection, and proper refrigerant charging. There is also a good amount of discussion on gas pool heaters - frequent component failures due to heat and corrosion issues, piping considerations due to their large BTU capacity, and combustion troubleshooting basics. Throughout the casual discussion, both hosts interject humor and personal stories related to their dealings with pool heater equipment, clients, and installations over the years. The overall message is that while heat pumps and gas pool heaters have some specialized considerations, much of the core knowledge needed to service them comes from foundational HVAC systems understanding combined with an awareness of the unique aspects covered in detail during this episode. Topics Covered: Types of pool heaters How heat pump and gas pool heater operation compare to HVAC Typical installation and service providers Key components and design aspects Common high-pressure issues and troubleshooting water flow problems Low ambient operation challenges Refrigerant charging considerations Gas piping sizing for large BTU appliances Corrosion issues and component failures Combustion testing basics Learn more about the 5th Annual HVACR Training Symposium at https://hvacrschool.com/Symposium24.

Bryan Orr hosted a live podcast discussion all about 90% efficient furnaces with HVAC professionals Ty Branaman, Adam Mufich, and Matthew Bruner. They covered the basics of how 90% furnaces work compared to traditional 80% furnaces, troubleshooting tips, and best practices for installation and service. A key difference with 90% furnaces is the addition of a secondary heat exchanger that extracts more heat from the exhaust gases before they go out the flue. This allows the furnace to achieve at least 90% efficiency. The condensing of water vapor in the exhaust also releases latent heat. However, the acidic condensate must be properly drained, and pipes must be corrosion-resistant. Proper airflow is also critical. The experts emphasized starting any service job by carefully looking over the furnace and venting. Check for any signs of problems like leaks, debris buildup, or animals/pests blocking vents. Verify gas supply and use combustion analysis to optimize performance. When troubleshooting, methodically trace through the sequence of operations. Pressure switches, flame sensors, and airflow issues are common culprits. The podcast concludes with a reminder that extensive training content on HVAC topics like this is available through HVAC School and other industry experts. Continuing education and an open, collaborative mindset are important for professional growth. Key topics covered: How 90% furnaces achieve higher efficiency with a secondary heat exchanger Water condensation and corrosion concerns - importance of drainage and pipe material Verifying gas supply, venting, airflow, and using combustion analysis Troubleshooting tips - visually inspecting, tracing sequence of operations, checking pressure switches and flame sensor Proper installation positioning and intake/exhaust vent sizing per manufacturer specifications View the entire livestream with Ty on our YouTube channel HERE.

In this short podcast, Bryan talks about where to place the micron gauge during evacuation and how to think about micron gauge positioning. Evacuation (deep vacuum) doesn't remove solid contaminants, and vaporizing liquid water is a time-consuming process; its main purpose is to remove water vapor, air, and nitrogen gases from the HVAC/R system. When you pull down below 500 microns and hold that pressure, we can make sure we have a clean, dry, and tight (leak-free) system. As we started using R-410A and POE oil, water in the system became a much bigger issue than it was with mineral oil (it was never to have water in the system, but it breaks down POE oil). Before we start pulling a vacuum on the system, we need to attach our micron gauge to the pump while it's isolated to make sure the pump is working. A modern vacuum pump should pull down below 100 microns in 30-60 seconds; if your pump can't pull down to 100 microns in under a minute when isolated, then you'll want to change the oil (possibly multiple times). Be sure to change the oil regularly and store it properly. When you pull a vacuum on a system, you'll want to attach your micron gauge as far away from the pump as possible to get an accurate indicator of your vacuum. Use core remover tools to isolate the system and make sure the far side of the system is brought below 500 microns during evacuation. The time it takes to pull down a system and the time you'll hold the vacuum will depend on your application (residential vs. commercial).

I was impressed with Austin Klokus when I first met him on a trip to Kalos Services (The Orr Family HVAC/Mechanical business in Clermont FL) a few years ago. He was working as a senior videographer at the time where he had soaked up knowledge from Bryan Orr and others and taught himself the skills necessary to do fulfill this role. I loved it when he used the phrase “air is stuff” in one of his videos to convey the message that air has mass. I saw him again in person recently at the 3rd Annual HVAC School Symposium and he continues to mature and grow as a person. I appreciate his “young wisdom” and I hope that you do, too.
