Do heat pumps work in Huntsville winters?

Winters in Huntsville are mild, so heating efficiency matters less than cooling. The average winter low is 35°F, and the heating season adds up to 2,831 heating degree days (NOAA 1991-2020 normals).

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

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $759 of electricity a year for heating and $506 for cooling in Huntsville, at the Alabama average of 16.5¢/kWh. The most efficient models cost less - see the rankings above.

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

Not on heating alone at today's prices: about $759 a year with a typical heat pump versus $736 with a 95% gas furnace (Alabama averages: 16.5¢/kWh, $1.69/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 Huntsville?

With average insulation, roughly a 3.5-ton system: the estimated cooling load is 32,100 BTU/h and the heating load 38,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
