Heat Pump Payback in Webster, TX
Should Webster switch to a heat pump?
This one's marginal in Webster: it only clears if you stay long enough. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. That premium is recovered through $314 of lower running costs every year, landing the payback clock at roughly 9.6 years. It's a genuine toss-up here, Webster's numbers don't point clearly either way.

How cold Webster actually gets
806 heating degree days pile up here every year, so Webster barely has a winter to speak of; the cooling side runs to 3571 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 32°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 19.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.15 on the standard unit fit for this climate. Webster's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Climate figures trace to the nearest NOAA station, Ellington Field Airport, 6.6 miles from Webster.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 648 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $596 a year. That compares with roughly 8 Mcf a year of gas at Webster's $19.42 per-Mcf rate, about $910 a year with the old AC included, against a local electricity rate of 16.15¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,711 ahead.
How sensitive Webster's result is to prices
In Webster the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Webster: the heat pump is worth it within a decade if it costs less than $3,140 more than replacing the furnace and AC, and within 7 years if the gap is under $2,198.
The other scenario: no gas furnace to begin with
Not every home in Webster has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
How Webster compares nationally
Webster lands at position 2969 out of 3206 cities on heating severity (coldest is 1), and 2721 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.
