Heat pump vs. gas furnace in Lakewood, CO

Lakewood is a place where a heat pump genuinely costs more to operate than the alternative. 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $157 a year here, so the extra spend stays unrecovered. That's Lakewood's own climate and rates talking, not a hedge or a caveat.

How cold Lakewood actually gets

4908 heating degree days pile up here every year, so Lakewood has a real but manageable winter; the cooling side runs to 1015 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -5.8°F, against a record low of -11.2°F. That puts the seasonal coefficient of performance at 2.56 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Lakewood sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, ATCT ROCKY MOUNTAIN METRO, 13.9 miles from Lakewood.

The month-to-month numbers for Lakewood

A 2000-square-foot house here would pull roughly 4,855 heating kilowatt-hours annually on top of cooling, totalling about $946 a year on electricity. That compares with roughly 51 Mcf a year of gas at Lakewood's 11.17 per-Mcf rate — about $788 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 $5,857 behind.

Electric resistance heat in Lakewood, compared

Plenty of homes in Lakewood heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Lakewood's answer improves. Switching saves about $1,326 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 6 years.

How Lakewood compares nationally

Among 3206 cities, Lakewood's winter puts it at rank 848 for severity, while its size puts it at rank 173 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Deciding what's next in Lakewood, CO

Lakewood, Colorado is home to about 156,868 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 Lakewood, nothing is lost by holding off until the current equipment genuinely fails.

Ask a local HVAC contractor for a quote before committing either way.

More on how this number was built

Nothing above is a black box: the methodology guide shows the full arithmetic behind Lakewood's 2.56 seasonal COP and payback figure. At a -5.8°F design temperature, Lakewood sits in cold-climate territory; the guide to that class of unit explains why.
