Heat Pump Payback in Brenham, TX
Should Brenham switch to a heat pump?
In Brenham, 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. Lower bills claw that back: about $306 saved annually, for a payback of roughly 9.8 years. Whether that's worth it in Brenham depends on how many years you expect to own the place.

The climate behind Brenham's payback figure
1108 heating degree days pile up here every year, so Brenham barely has a winter to speak of; the cooling side runs to 3260 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 26.4°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 14.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.99 on the standard unit fit for this climate. A standard ducted system is enough here; Brenham's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, Brenham Municipal Airport, 4.4 miles from Brenham.
The yearly running costs in Brenham
Electricity use for heating alone comes out to about 938 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $600 a year. Brenham's gas rate of $19.42 per Mcf, applied to the 12 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $906 a year, against 16.15¢ per kWh for electricity. 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 $1,590 ahead.
The break-even point in Brenham
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 Brenham at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $306 a year saved, a difference under $2,142 pays back within 7 years here, and under $3,060 within 10.
The other scenario: no gas furnace to begin with
Not every home in Brenham has gas service. Swap the comparison to resistance heat instead of gas, and Brenham's answer improves. Switching saves about $535 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $7,500 spent up front comes back in about 14 years.
How Brenham compares nationally
Brenham lands at position 2852 out of 3206 cities on heating severity (coldest is 1), and 1950 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.
