Frequently asked questions

How do heat pumps save money?

They move heat instead of making it, delivering 2 to 4 units of heat per unit of electricity versus 1 for resistance.

Heat pump vs gas furnace?

Compare electric rate per kWh against gas per therm with efficiency. Heat pumps usually win above freezing and in mild climates.

What is HSPF and COP?

Higher means more heat per watt. Cold-climate models hold COP above 2 well below freezing.

When do heat pumps lose?

Poorly insulated homes and very low gas prices narrow the gap. Fix the envelope first.
