Heat Pump Payback in Hewitt, TX
Heat pump vs. gas furnace in Hewitt, TX
The payback math works in Hewitt on paper, past the equipment's own working life. $5,500 is what Hewitt would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $333 saved annually, for a payback of roughly 16.5 years. Hewitt's own numbers say this pencils out only in theory, not in practice.

Why Hewitt's climate drives this number
1563 heating degree days pile up here every year, so Hewitt has a mild winter by US standards; the cooling side runs to 3138 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 16°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 12°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.08 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 16°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Hewitt.

The yearly running costs in Hewitt
Electricity use for heating alone comes out to about 1,285 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $640 a year. The gas furnace it replaces burns roughly 16 Mcf a year at $19.42 per Mcf here, for a running cost near $973 a year including the old AC (electricity here runs 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 $501 behind.
What would change Hewitt'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 Hewitt at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $333 a year saved, a difference under $2,331 pays back within 7 years here, and under $3,330 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Hewitt heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Hewitt's answer improves. Even against resistance heat, the running-cost gap here isn't enough to clear the $10,000 incremental cost within the equipment's 15-year life.
How Hewitt compares nationally
Among 3206 cities, Hewitt's winter puts it at rank 2664 for severity, while its size puts it at rank 2219 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
