More heat pumps were sold in 2022 than gas furnaces. And that was before the Inflation Reduction Act (IRA) kicked in, which provides an $8,000 rebate for most heat pump installations — on top of a $2,000 federal tax credit and city/county incentives that can exceed $3,000.

Heat pumps are cleaner, more efficient and less expensive than most conventional gas furnaces and air conditioners. But the variety in heat pump system configurations, efficiency, and costs is enough to make even a geeky engineer’s head spin when trying to determine the best solution for a particular home.

My guest on this week’s Energy Show is Dennis Stinson, VP of Sales at Fujitsu General America. Dennis has been in the heat pump business for over 30 years. Along the way he’s accumulated a wealth of practical knowledge about heat pump installations for just about every type of building in the U.S.

So if you’re wondering what the difference is between a ducted and ductless system, why high efficiency heat pumps use inverters (but not the solar kind), the importance of variable speed fans and compressors, the meaning of a mini-split cassette (this happened to me when I ran over my collection of 70s classic rock tapes), the difference between SEER and COP efficiency metrics, or whether or not a roll of duct tape can seal your ducts — I think you’ll get a lot out of this week’s Energy Show.
