Heat Pump Payback in League City, TX
Will a heat pump pay off in League City, TX?

The climate behind League City's payback figure
795 heating degree days pile up here every year, so League City barely has a winter to speak of; the cooling side runs to 3633 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 32°F here (coldest 2024 reading 19.9°F), which works out to a seasonal COP of 3.15 for the standard class of unit this climate calls for. A standard ducted system is enough here; League City's design temperature doesn't justify the cold-climate premium. These numbers come from Clover Field Airport, the closest NOAA station, 8.2 miles out.
The yearly running costs in League City
Electricity use for heating alone comes out to about 639 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $603 a year. That compares with roughly 8 Mcf a year of gas at League City's $19.42 per-Mcf rate, about $921 a year with the old AC included, against a local electricity rate of 16.15¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,766 ahead.
What would change League City's answer
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 League City at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $318 a year saved, a difference under $2,226 pays back within 7 years here, and under $3,180 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in League City heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. 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.
How League City compares nationally
League City lands at position 2972 out of 3206 cities on heating severity (coldest is 1), and 252 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.
