Heat pump vs. gas furnace in Monument, CO
Here in Monument, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). The heat pump would cost about $193 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Monument's numbers say wait.
Why Monument's climate drives this number
Monument has a cold winter that leans hard on heating equipment — 5920 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 581 cooling degree days. -0.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -17.9°F on file. Worked through the model, that's a seasonal COP of 2.68 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Monument — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from USAF ACADEMY AIRSTRIP AIRPORT, the closest NOAA station, 7.6 miles out.
The month-to-month numbers for Monument
A 2000-square-foot house here would pull roughly 5,593 heating kilowatt-hours annually on top of cooling, totalling about $1,006 a year on electricity. Monument's gas rate of 11.17 per Mcf, applied to the 62 Mcf a year the furnace burns, puts its running cost near $813 a year, against 16.53¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $6,400 behind.
The other scenario: no gas furnace to begin with
Not every home in Monument has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,596 a year comes back this way, enough that the 5-year payback clears the $8,000 premium comfortably within the equipment's life.
How Monument compares nationally
Monument lands at position 261 out of 3206 cities on heating severity (coldest is 1), and 2597 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
