Do heat pumps work in Salem winters?

Winters in Salem are moderate - about 2.4 nights a year at or below 20°F - and any modern variable-speed heat pump handles them. The average winter low is 36°F, and the heating season adds up to 4,340 heating degree days (NOAA 1991-2020 normals).

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

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $1,091 of electricity a year for heating and $99 for cooling in Salem, at the Oregon average of 15.6¢/kWh. The most efficient models cost less - see the rankings above.

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

Not on heating alone at today's prices: about $1,091 a year with a typical heat pump versus $1,068 with a 95% gas furnace (Oregon averages: 15.6¢/kWh, $1.61/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 Salem?

With average insulation, roughly a 4-ton system: the estimated cooling load is 27,600 BTU/h and the heating load 46,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.
