Practical answers to the questions that actually matter.

Case studies show what happened in one specific home. Guides explain the reasoning you can apply to yours — correct sizing, backup heat strategy, cold-climate performance, and ducted vs. ductless — so you can evaluate your own situation instead of just reading someone else's.

This section is new. The first guides are in progress and will publish over the coming weeks. Have a topic you'd like covered first? Tell us.

Heat Pumps in Cold Climates

Why cold-climate (ccASHP) units keep delivering heat down to −15°F to −20°F, what "balance point" actually means for your backup heat strategy, and which climates make a heat pump an easy call versus a genuinely close comparison.

Sizing a Heat Pump Correctly

Why "bigger is safer" is the wrong instinct with heat pumps, what a proper Manual J load calculation catches that a contractor's rule of thumb misses, and the real cost of oversizing versus undersizing.

Ducted vs. Ductless: Which Fits Your Home

Central ducted heat pumps versus mini-split ductless systems — installed cost differences, efficiency trade-offs, and which homes are genuinely better suited to each approach.

In development

Backup Heat Strategies

Resistance strip heat, dual-fuel pairing with an existing furnace, and oversized-capacity approaches — how each affects your total cost of ownership when temperatures drop below the heat pump's balance point.

Want to run the numbers first?

While the guides library is in development, the calculators already model every cost category for your specific ZIP code and home.
