Do heat pumps work in Bridgeport winters?

Bridgeport sees about 26 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 27°F, and the heating season adds up to 5,140 heating degree days (NOAA 1991-2020 normals).

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

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $2,312 of electricity a year for heating and $388 for cooling in Bridgeport, at the Connecticut average of 28.2¢/kWh. The most efficient models cost less - see the rankings above.

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

Not on heating alone at today's prices: about $2,312 a year with a typical heat pump versus $1,258 with a 95% gas furnace (Connecticut averages: 28.2¢/kWh, $1.62/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 Bridgeport?

With average insulation, roughly a 4-ton system: the estimated cooling load is 30,600 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.
