Heat Pump Payback in Texas City, TX
Texas City, TX: the heat pump payback math
In Texas City, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Texas City's residents would see roughly $329 a year back in running costs, putting the payback around 9.1 years. Whether that's worth it in Texas City depends on how many years you expect to own the place.

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, and the coldest daily reading in the 2024 station record was 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 including the old AC (electricity here runs 16.15¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,940 ahead.
How sensitive Texas City's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Texas City at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $329 a year saved, a difference under $2,303 pays back within 7 years here, and under $3,290 within 10.
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. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
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.

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 Texas City's 3.22 seasonal COP and payback figure. Not every home in Texas City has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
