Brentâs journey from building climate-tech software to starting one of the most compelling HVAC events in the country is a case study in how community, business strategy, and technical know-how can come together to drive real change.
And the Summit? Itâs not just another trade show. Itâs two days of contractor-focused training, business insights, and peer-to-peer learningâall built around the future of HVAC.
What youâll learn
Why Brent Davidson started a contractor-first summitâand how it grewHow heat pump conversations differ from solar, and why that mattersWhat makes a good installationâand why business structure is keyHow community and peer learning can drive quality at scaleWhat to expect from the next Summit in Worcester, MAWhat Makes the US Heat Pump Summit Different?
Brentâs focus is simple: put the right people in the room and spark the right conversation. That means:
Business and technical content side by sideContractor-first agendaânot just utility program talkPeer-driven roundtables, not just sales boothsNational trends + regional relevance (hello, cold climate heat pumps)Itâs the only event where the people in the room actually want to talk about Manual J, coefficients of performance, electric strip backups vs. supplemental dehumidification, and customer acquisition in the same breath.
Why This Matters
Heat pumps are gaining groundâbut success doesnât come from equipment alone. It comes from design, training, and business models that reward quality. Thatâs what the Summit is about.
And Brent? Heâs not trying to run yet another conference. Heâs trying to help build an industry.

We (Eric and Ed) started the Heat Pump Podcast on a whim. After two years immersed in HVAC, heat pumps, and home electrification, we had a realization: thereâs a lot of great HVAC content out there, but heat pump-focused conversations? Surprisingly scarce.
This didnât sit right with us.
Arenât heat pumps the best HVAC equipment on the market today?Arenât their COPs practically magic?Arenât heat pumps the future of HVAC?So why was the discussion around them so⌠occasional?
To see if we could change that, we launched the Heat Pump Podcast as an experiment. Whatâs happened since has blown us away.
What Weâve Learned
After 7 months, 15 episodes, a rapid rise in listeners, and great feedback from heat pump-focused entrepreneurs, we took a moment to reflect. In this latest episode, we compare notes and share the biggest lessons weâve learned along the way. Such as:
1. We love it. Turns out, weâd do this even if no one listened. Every episode has been an incredible learning experience.
2. There are way more heat pump-focused entrepreneurs than we imagined!
3. Designing for heat pump systems is way harder than conventional equipment
4. You can't make up for bad design
5. Focusing on heat pumps creates a winning business
6. Heat pumps. Are. More. Comfortable. Period.
Tune in to the episode for our top 10 lessons from the Heat Pump Podcast Season 1!
A Heartfelt Thanks
To our incredible guests: thank you for taking a chance on two heat-pump-obsessed entrepreneurs with a niche podcast idea. Your time and insights have made every episode richer.
Whatâs Next?
Weâre just getting started. With more episodes planned for 2025, weâre excited to keep growing the conversation around heat pumps, HVAC innovation, and building science.
đ§ Tune in to this special reflection episode and join us on the journey!

What if you could do to construction what Amazon did to retail? Or what Uber did to taxis?
Mark Kasdorf has an ambitious vision to do just that, and his journey starts with heat pumps.
Mark is the founder and CEO of Forge, a venture-backed, mission-driven startup tackling one of Americaâs biggest challenges: the skilled labor shortage in the trades. Forgeâs secret? Recruiting great talent, training them quickly, and empowering them to lead their own crews fast. Really fast.
In just 18 months, Forge went from installing its first heat pump to running over 10 crews across New Englandâall through organic growth, no acquisitions Thatâs a pace unheard of in the HVAC space, where reaching 10+ crews can take years.
Mark describes HVAC as the âgoldilocks tradeââchallenging enough to require specialized training, but more scalable than electrical or plumbing, which require more licensing. Within HVAC, Forge is laser-focused on heat pumps, a decision that reflects the size of the market, profitability, and growth prospects.
In this podcast episode, Mark shares fascinating insights into:
⢠Forgeâs rapid journey from one crew to many.
⢠His roadmap for scaling to $10M, $100M, and beyond.
⢠Why the trades can't be âgigifiedâ and what that means for the construction industry.
⢠Lessons learned from other startupsâ failures to disrupt the trades.
⢠What makes Forge both similar to and different from a traditional heat pump company.
Whether youâre curious about how venture capitalists see the HVAC industry, or you want a fresh perspective on heat pumps, this episode is a must-listen.
Listen now to hear why Mark believes HVAC is the ultimate trade and why heat pumps are at the center of it all.

Adam Mufich is a multi-generation HVAC entrepreneur and now trainer for the National Comfort Institute. What does Adam like to do in his free time? Talk about HVAC.
Adam first caught our attention with his HVAC School article Good COP - Bad COP. He impressed us again with his presentation at the NCI Summit "How to Properly Design with Today's Heat Pumps." We highly recommend both.
On this podcast, Adam dives into his educational journey, sharing how he finally stopped delaying his learning and dove in feet first. He started down the rabbit hole with a Manual J class by Alex Meaney and reading Nate Adams' book. As he went deeper and deeper, one of his first big realizations was: properly done load calculations can be nerve-wracking (at first) when you see how much smaller they are than expected.
What makes this episode particularly fun is Adamâs story of applying his newfound knowledge to his own home. He installed a Daikin SkyAir heat pump and then tackled infiltration by meticulously hand caulking his roof, leak by leak. As a result of his efforts, he significantly reduced his homeâs load. Taking it a step further, and with advice from Roman Baugh, Adam reprogrammed his Daikin SkyAir to function as a 1.5-ton heat pump instead of its original 3-ton capacity.
The results? Even at half capacity, the system performed beautifully.
This podcast episode strikes a perfect balance between theory and practice, offering invaluable insights for contractors looking to improve heat pump performance. Whether youâre just starting your HVAC learning journey or looking for actionable tips, this episode is packed with inspiration and expertise.

So far, most of our episodes have focused on HVAC companies. Today, we branch out, interviewing Fortunat Mueller, co-founder and CEO of ReVision Energy. ReVision started out as a solar company, but over time has become an "energy transition company." A major part of their business is installing heat pumps.
In this episode, we dig into what it means to be an energy transition company. Fortunat explains how and why ReVision got into HVAC, and in particular why they focus exclusively on heat pumps. He lays out why solar and heat pumps fit naturally into a single business model, and why ReVision's many offerings perfectly meet the energy transition experience that is most comfortable for homeowners. Few homeowners want to do it all in one go. Instead, they'd rather tackle it piece by piece over the course of many years.
Fortunat shares a lot, such as:
How ReVision evolved over timeHow companies are built, not from one big idea, but from countless smaller decisions over years that work together to create something greatReVision's focus on training as a competitive advantage when there is a dramatic shortage of tradespeopleHow heat pumps perform in the real world, even in climates as brutal as Maine'sHow heat pump technology has evolved and improved over timeWhat an ESOP is and why it's a competitive advantage...... And lots moreWhether you're a solar company thinking about getting into heat pumps -- or if you're an HVAC company wondering how your competition is evolving -- you'll get a lot out of this episode.
