Texas City, TX: the heat pump payback math
In Texas City, a heat pump pays for itself within a reasonable window. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Texas City's residents would see roughly $329 a year back in running costs, putting the payback around 3 years. That's a real payback, built from Texas City's own climate and utility rates, not a national guess.
Why Texas City's climate drives this number
Degree days tell the story here: Texas City racks up 630 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3937 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 34.3°F, against a record low of 22.1°F. That puts the seasonal coefficient of performance at 3.22 for the recommended standard unit. A standard ducted system is enough here; Texas City's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, EAGLE POINT, 3.6 miles from Texas City.
Texas City's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 495 kWh a year to keep it warm, plus cooling, for a combined electric bill near $622 a year. The gas furnace it replaces burns roughly 7 Mcf a year at 19.42 per Mcf here, for a running cost near $951 a year (electricity here runs 16.15¢/kWh). Buy it outright, not incrementally, and payback stretches to 33.4 years; over 15 years the net position sits $3,940 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Texas City 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 $460 a year, which recovers the extra $5,500 spent going electric in roughly 12 years.
Where Texas City ranks in this dataset
Texas City lands at position 3017 out of 3206 cities on heating severity (coldest is 1), and 709 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
