Do heat pumps work in Sioux Falls winters?

Sioux Falls averages 25 nights a year at or below 0°F, so pick a cold-climate certified model and check its output at 5°F. The average winter low is 12°F, and the heating season adds up to 7,249 heating degree days (NOAA 1991-2020 normals).

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

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $1,655 of electricity a year for heating and $181 for cooling in Sioux Falls, at the South Dakota average of 14.3¢/kWh. The most efficient models cost less - see the rankings above.

Is a heat pump cheaper than a gas furnace in Sioux Falls?

Not on heating alone at today's prices: about $1,655 a year with a typical heat pump versus $1,044 with a 95% gas furnace (South Dakota averages: 14.3¢/kWh, $0.95/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 Sioux Falls?

With average insulation, roughly a 5-ton system: the estimated cooling load is 27,600 BTU/h and the heating load 60,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.
