Heat Pump Payback in Broomfield, CO
Heat pump vs. gas furnace in Broomfield, CO
Here in Broomfield, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Broomfield would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $195 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Broomfield's numbers say wait.

The climate behind Broomfield's payback figure
Broomfield has a cold winter that leans hard on heating equipment, 5528 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 852 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -5.4°F, and the coldest daily reading in the 2024 station record was -20.6°F. That puts the seasonal coefficient of performance at 2.57 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Broomfield sits firmly in cold-climate territory, so that's the class of unit priced here.

Broomfield's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 5,447 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,020 a year. The gas furnace it replaces burns roughly 58 Mcf a year at $11.17 per Mcf here, for a running cost near $826 a year including the old AC (electricity here runs 16.53¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $8,422 behind.
The break-even point in Broomfield
The heat pump would become the cheaper option in Broomfield if electricity fell to 12.7¢/kWh (from 16.53¢) or gas rose above $14.55 per Mcf (from $11.17). At today's prices a cheaper quote cannot rescue the gas comparison in Broomfield, since there is no yearly saving to recover it from.
Electric resistance heat in Broomfield, compared
Not every home in Broomfield has gas service. Swap the comparison to resistance heat instead of gas, and Broomfield's answer improves. About $1,476 a year comes back this way, enough that the 6.8-year payback clears the $10,000 premium comfortably within the equipment's life.
