Heat pump vs. gas furnace in Durango, CO

Durango is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Durango would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Running costs here land $204 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Durango's own climate and rates talking, not a hedge or a caveat.

Durango's weather, in the numbers that matter

6074 heating degree days pile up here every year, so Durango has a cold winter that leans hard on heating equipment; the cooling side runs to 428 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 0°F here (record low -16.1°F), which works out to a seasonal COP of 2.7 for the cold-climate class of unit this climate calls for. Durango needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from DURA-LA PLATA CO AIRPORT, the closest NOAA station, 10.5 miles out.

The month-to-month numbers for Durango

Electricity use for heating alone comes out to about 5,696 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,002 a year. That compares with roughly 63 Mcf a year of gas at Durango's 11.17 per-Mcf rate — about $798 a year — against a local electricity rate of 16.53¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $6,555 behind.

If your home heats with electric baseboard instead of gas

Not every home in Durango has gas service. Swap the comparison to resistance heat instead of gas, and Durango's answer improves. Switching saves about $1,632 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.9 years.

How Durango compares nationally

Durango lands at position 182 out of 3206 cities on heating severity (coldest is 1), and 1942 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.

Deciding what's next in Durango, CO

Durango, Colorado is home to about 19,811 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Durango, nothing is lost by holding off until the current equipment genuinely fails.
