What separates an average HVAC installation from a truly high-performing system? In this episode, David Richardson joins the Heat Pump Podcast to explore the principles behind high-performance HVAC. The conversation covers everything from airflow and static pressure to building science, duct system performance, heat pump design, and homeowner communication. 

David Richardson is Vice President of Training at the National Comfort Institute (NCI) and one of the most respected educators in the HVAC industry. With decades of field experience, David has helped thousands of contractors improve system performance through measurement, testing, and verification.

Expect to Learn:

• The equipment is not the system. David's central argument: the box is just one component. The system is what each contractor custom-manufactures on site with the ducts, airflow, and workmanship around it. Same equipment, two installs, two completely different results.
• The average system delivers about 57% of its capacity into the space where people actually live — not at the equipment, in the room. High-performance work can push that to ~88%. The 88% isn't better equipment; it's attention to detail.
• Duct location is the biggest lever. After that, duct leakage. David is blunt that leakage inside the conditioned space still counts — if the air isn't reaching the farthest room, those are BTUs you didn't deliver.
• Heat pumps cut your temperature rise roughly in half. An old furnace might run a 60-degree rise; a heat pump replacing it may run half that or less. Duct losses you got away with behind a furnace start eating real capacity behind a heat pump.
• Pressure and airflow can both check out while the system still underperforms. Temperature is the measurement that catches it — always verify delivered BTUs, not just readings at the equipment.
• Don't drown the homeowner in data. When people don't understand what you're telling them, they panic and grab the one thing they do understand: price. Great work loses to the cheap bid because of communication, not competence.

Heat pumps fail homes for one reason more than any other: someone guessed instead of measured. In this episode, Amply co-founder and co-CEO Eric Fitz shares his complete heat pump sizing playbook in a talk recorded at the Building Performance Association's annual conference in Columbus.

Eric is a mechanical engineer and a self-described Manual J nerd, and he takes you through the whole chain of system design: how Manual J defines what the home needs, why duct capacity is its own separate check that can make or break a retrofit, and how Manual S picks the right equipment. Along the way he shares the quick field tricks that remove the guesswork — the ten-second flashlight test for low-E glass, the $3 tool for checking wall insulation, and why a thicker filter actually fixes high static pressure.

You'll also hear plenty of audience Q&A from the room.

Expect to Learn

• Why accurate Manual J load calculations are the foundation of successful heat pump system design.
• How infiltration, windows, insulation, and duct leakage dramatically affect heating and cooling loads.
• Methods for measuring duct capacity and identifying airflow restrictions before equipment selection.
• How to interpret heat pump performance data, including capacity, COP, latent cooling, and airflow requirements.
• The tradeoffs between oversized and undersized systems, and how proper sizing improves comfort, efficiency, and indoor air quality.

In this episode of the Heat Pump Podcast, host Ed Smith sits down with Paul Bojko, owner of A-Guy Heating & Air, to explore what it really takes to build and scale a heat pump–focused HVAC business.

Paul shares his journey from military service and mechanical work to launching his own company and ultimately specializing in ductless heat pump systems. He breaks down how focusing on a niche, investing in branding, and embracing non-traditional marketing strategies helped transform his business.

The conversation dives into the realities of running an HVAC company, from early struggles and burnout to building a team, improving processes, and shifting from technician to business owner. Paul also explains why proper system design and load calculations are critical, and how many contractors still get it wrong.

They also explore how content creation, social media, and even radio partnerships are becoming powerful tools for growth in today’s HVAC landscape.

Expect to Learn

• In a market with only 50–60 mini split contractors, niching down beats competing with every HVAC truck in town.
• The mechanical install is the easy part — sizing the system right is the work most contractors skip.
• Chicago homes with 120,000 BTU furnaces keep coming back needing 50,000 or less. Believe the numbers once you've measured enough of them.
• Right-sizing will cost you some jobs. Stand behind the number anyway — offer to re-run it, but don't cave to "bigger is better."
• "Traditional" marketing is now Google and Facebook ads. Sponsoring a local radio host was Paul's fastest-working channel.
• Teaching at a community college doubles as a months-long job interview — two of Paul's hires came through it.
• Your brand isn't an afterthought. A memorable name and mascot made A-Guy identifiable in a sea of look-alike contractors.

Chris Morin is the founder of HVAC Pro Blog, an ACCA system design instructor, and one of the few people in the industry who trains both contractors and building inspectors. In this episode, he makes a compelling case for why aggressive load calculations, code compliance, and building inspector relationships aren't just good building science — they're how you grow a more profitable business. We also dig into duct design fundamentals, the oversizing trap, and why "I never get callbacks" is the most dangerous metric in HVAC.

Expect to Learn

• Half of contractors aren't doing load calcs — and a significant share of the half that do aren't doing them accurately. An aggressive Manual J is the foundation for everything.
• "No callbacks" is a dangerous metric. The real measure of success is a maintenance customer who calls you back every season — and refers you to their neighbors.
• Building inspectors aren't the enemy. The contractors who build relationships with them and meet code requirements end up with less competition and higher margins.
• Oversizing for the coldest 1% of the year creates problems during the other 98%. Variable speed technology helps, but it doesn't fix bad design.
• System design isn't an overhead cost — it's a service you charge for that separates your proposal from the low bidder's guess.
