Cheapest heat pumps to run in Pennsylvania
Ranked by estimated yearly cost if each model served the same 36,000 BTU/h (3-ton) load in Pennsylvania, so size doesn't distort the comparison. Because Pennsylvania's climate weights heating more heavily, HSPF2 (heating efficiency) matters most here. Choosing the most efficient model over the least efficient one in our database saves about $1,115 a year for the same load.

Best cold-weather performers for Pennsylvania
Pennsylvania is a cold state, so heating dominates the bill and backup resistance heat is the biggest risk to running costs. These cold-climate certified models keep the most of their heating capacity at 5°F.

Heat pump vs. gas furnace in Pennsylvania
To heat the same home (2,000 full-load heating hours at 36,000 BTU/h) in Pennsylvania, a typical heat pump (HSPF2 9.5) would cost about $1,650 a year, an efficient one (HSPF2 10) about $1,567, versus $1,099 for a 95% gas furnace and $1,305 for an older 80% furnace, at Pennsylvania's average residential gas price of $15.04 per thousand cubic feet. With cheap gas and comparatively expensive electricity, gas heating is cheaper to run in Pennsylvania. A dual-fuel system (heat pump plus gas backup) is often the lowest-cost setup here.
Heating only; a heat pump also provides cooling, while a furnace needs a separate air conditioner. Gas prices: EIA, residential, annual average. Compare all states.

Frequently asked questions
How much does it cost to run a heat pump in Pennsylvania?
Using Pennsylvania's average residential electricity price of 21.77¢/kWh, a typical 3-ton, median-efficiency heat pump costs about $2,062 a year to run. The most efficient model in our database would cost about $1,307 for the same load.
Is electricity expensive in Pennsylvania?
Pennsylvania's residential rate of 21.77¢/kWh is 20% above the U.S. average of 18.16¢ and ranks #14 most expensive of 51 (EIA, August 2026).
Is heating or cooling the bigger cost in Pennsylvania?
With our climate assumptions for Pennsylvania (2,000 heating and 800 cooling hours), heating accounts for about 80% of a typical heat pump's yearly energy use.
Is a heat pump cheaper than gas heat in Pennsylvania?
For a typical home, heating with an efficient heat pump costs about $1,567 a year versus $1,099 with a 95% gas furnace at Pennsylvania's average prices. With cheap gas and comparatively expensive electricity, gas heating is cheaper to run in Pennsylvania. A dual-fuel system (heat pump plus gas backup) is often the lowest-cost setup here.
