Heat Pump Payback in Gatesville, TX
Gatesville, TX: the heat pump payback math
In Gatesville, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Gatesville would pay extra to go electric rather than replace the furnace and AC with the same again. Gatesville's residents would see roughly $327 a year back in running costs, putting the payback around 16.8 years. That's a technicality, not a recommendation, for anyone actually living in Gatesville.

How cold Gatesville actually gets
Degree days tell the story here: Gatesville racks up 1551 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3062 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 15.8°F, and the coldest daily reading in the 2024 station record was 14°F. That puts the seasonal coefficient of performance at 3.08 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 15.8°F design temperature Gatesville falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. These numbers come from Gatesville Municipal Airport, the closest NOAA station, 3.5 miles out.
The yearly running costs in Gatesville
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,275 kWh a year to keep it warm, plus cooling, for a combined electric bill near $628 a year. The gas furnace it replaces burns roughly 16 Mcf a year at $19.42 per Mcf here, for a running cost near $955 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 $595 behind.
How sensitive Gatesville's result is to prices
In Gatesville 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 Gatesville: the heat pump is worth it within a decade if it costs less than $3,270 more than replacing the furnace and AC, and within 7 years if the gap is under $2,289.
Electric resistance heat in Gatesville, compared
Plenty of homes in Gatesville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Gatesville's answer improves. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Gatesville against the rest of the country
Ranked against the other 3206 cities covered, Gatesville comes in at 2673 for heating severity, 1 would be the coldest place in the dataset, and 2261 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Gatesville's figure comes from
Every constant behind this page, the 3.08 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Gatesville's 15.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
