Heat Pumps
Why Homeowners Are Making the Switch
One system, two jobs
Heating in winter, cooling in summer — one piece of equipment replaces both your furnace and your AC.
Serious efficiency
Heat pumps move heat instead of creating it, delivering two to three times more heating per dollar of electricity than traditional electric heat.
Built for cold climates
Today’s cold-climate models maintain strong output well below zero — a genuine leap from heat pumps of even a decade ago.
Dual-fuel flexibility
Pair a heat pump with a gas furnace that takes over automatically on the deepest cold snaps: efficiency 90% of the winter, furnace muscle for the polar vortex days.
Rebates and incentives
Federal tax credits and utility rebates can significantly reduce your installed cost. Programs change frequently — ask what’s available when you get your quote.
We’ll tell you honestly which configuration fits your home, your existing equipment, and your budget — not push whichever way the incentive winds are blowing.

How Heat Pumps Work
A heat pump doesn’t create heat — it moves it. In summer, it pulls heat out of your house like a normal air conditioner. In winter, it runs in reverse, extracting heat from the outdoor air and moving it inside. Moving heat takes far less energy than generating it which is why heat pumps create such efficiency.

FAQ
Common Heat Pump Questions
Are heat pumps more efficient than furnaces?
For most of the heating season, yes — often dramatically. In extreme cold their efficiency drops, which is why dual-fuel setups are popular here: each technology handles the conditions it’s best at.
How long do heat pumps last?
Typically around 15 years with proper twice-yearly maintenance. Because they run year-round, maintenance matters even more than it does for a furnace or AC alone.
Can a heat pump replace both my furnace and my air conditioner?
Yes — that’s the core appeal. One system, both jobs. Whether full replacement or dual-fuel makes more sense for your home is exactly what our in-home assessment sorts out.
My heat pump is covered in ice — is that normal?
Light frost in winter is normal, and the system’s defrost cycle handles it. Thick ice that never clears is not — it usually points to a defrost control or refrigerant problem worth a service call.
