Do heat pumps work in Roseville winters?

Winters in Roseville are mild, so heating efficiency matters less than cooling. The average winter low is 39°F, and the heating season adds up to 2,644 heating degree days (NOAA 1991-2020 normals).

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

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $1,391 of electricity a year for heating and $631 for cooling in Roseville, at the California average of 33.1¢/kWh. The most efficient models cost less - see the rankings above.

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

Not on heating alone at today's prices: about $1,391 a year with a typical heat pump versus $844 with a 95% gas furnace (California averages: 33.1¢/kWh, $2.12/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 Roseville?

With average insulation, roughly a 3.5-ton system: the estimated cooling load is 30,600 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.
