Do heat pumps work in Dearborn winters?

Dearborn sees about 45 nights a year at or below 20°F. A cold-climate certified model keeps the house warm without leaning on backup heat. The average winter low is 22°F, and the heating season adds up to 6,067 heating degree days (NOAA 1991-2020 normals).

How much does it cost to run a heat pump in Dearborn?

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $2,058 of electricity a year for heating and $267 for cooling in Dearborn, at the Michigan average of 21.0¢/kWh. The most efficient models cost less - see the rankings above.

Is a heat pump cheaper than a gas furnace in Dearborn?

Not on heating alone at today's prices: about $2,058 a year with a typical heat pump versus $975 with a 95% gas furnace (Michigan averages: 21.0¢/kWh, $1.05/therm). A high-HSPF2 model narrows the gap, and a heat pump also replaces the air conditioner. Against propane, oil or electric heat it is usually far cheaper.

What size heat pump do I need for a 2,000 sq ft house in Dearborn?

With average insulation, roughly a 5-ton system: the estimated cooling load is 27,600 BTU/h and the heating load 54,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.
