Cold-Climate Heat Pump Decision Kit
The full working version of the free check. Fifteen pages of fill-in worksheets that run on your own numbers: what you actually pay for heat, the four spec numbers to demand in writing, the outdoor temperature where a heat pump stops saving you money at your rates, a side-by-side quote comparison, and a scorecard that lands on go, caution, or don’t buy.
