Heat pump vs. gas furnace in The Colony, TX
The Colony sits right on the fence — how long you'll own the house decides this one. $3,500 is what The Colony 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. The Colony's residents would see roughly $361 a year back in running costs, putting the payback around 9.7 years. It's a genuine toss-up here — The Colony's numbers don't point clearly either way.
How cold The Colony actually gets
1620 heating degree days pile up here every year, so The Colony has a mild winter by US standards; the cooling side runs to 3408 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 18.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 9.5°F on file. Worked through the model, that's a seasonal COP of 3.15 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, The Colony sits firmly in cold-climate territory, so that's the class of unit priced here.

The Colony's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 1,302 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $680 a year. The Colony's gas rate of 19.42 per Mcf, applied to the 17 Mcf a year the furnace burns, puts its running cost near $1,041 a year, against 16.15¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 37.4 years, leaving the 15-year total $1,920 ahead.
If your home heats with electric baseboard instead of gas
Not every home in The Colony has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $696 a year, which recovers the extra $8,000 spent going electric in roughly 11.5 years.
How The Colony compares nationally
Ranked against the other 3206 cities covered, The Colony comes in at 2646 for heating severity — 1 would be the coldest place in the dataset — and 893 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Next step for 45,897 people in The Colony
The Colony, Texas is home to about 45,897 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 The Colony, nothing is lost by holding off until the current equipment genuinely fails.
