Cheapest heat pumps to run in Colorado
Ranked by estimated yearly cost if each model served the same 36,000 BTU/h (3-ton) load in Colorado, so size doesn't distort the comparison. Because Colorado'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 $857 a year for the same load.

Best cold-weather performers for Colorado
Colorado 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 Colorado
To heat the same home (2,000 full-load heating hours at 36,000 BTU/h) in Colorado, a typical heat pump (HSPF2 9.5) would cost about $1,301 a year, an efficient one (HSPF2 10) about $1,236, versus $816 for a 95% gas furnace and $969 for an older 80% furnace, at Colorado's average residential gas price of $11.17 per thousand cubic feet. With cheap gas and comparatively expensive electricity, gas heating is cheaper to run in Colorado. 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 Colorado?
Using Colorado's average residential electricity price of 17.17¢/kWh, a typical 3-ton, median-efficiency heat pump costs about $1,586 a year to run. The most efficient model in our database would cost about $1,012 for the same load.
Is electricity expensive in Colorado?
Colorado's residential rate of 17.17¢/kWh is 5% below the U.S. average of 18.16¢ and ranks #22 most expensive of 51 (EIA, August 2026).
Is heating or cooling the bigger cost in Colorado?
With our climate assumptions for Colorado (2,000 heating and 700 cooling hours), heating accounts for about 82% of a typical heat pump's yearly energy use.
Is a heat pump cheaper than gas heat in Colorado?
For a typical home, heating with an efficient heat pump costs about $1,236 a year versus $816 with a 95% gas furnace at Colorado's average prices. With cheap gas and comparatively expensive electricity, gas heating is cheaper to run in Colorado. A dual-fuel system (heat pump plus gas backup) is often the lowest-cost setup here.
