Heat Pump Payback in Saginaw, TX
Will a heat pump pay off in Saginaw, TX?
In Saginaw, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $353 saved annually, for a payback of roughly 15.6 years. That's a technicality, not a recommendation, for anyone actually living in Saginaw.

How cold Saginaw actually gets
1912 heating degree days pile up here every year, so Saginaw has a mild winter by US standards; the cooling side runs to 3091 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 15.1°F, and the coldest daily reading in the 2024 station record was 8.1°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 15.1°F design temperature Saginaw 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. Climate figures trace to the nearest NOAA station, Ft Worth Meacham International Airport, 3.2 miles from Saginaw.
The yearly running costs in Saginaw
Electricity use for heating alone comes out to about 1,582 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $681 a year. The gas furnace it replaces burns roughly 20 Mcf a year at $19.42 per Mcf here, for a running cost near $1,034 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 $212 behind.
How sensitive Saginaw's result is to prices
Gas would only overtake the heat pump in Saginaw if electricity rose past 182.7¢/kWh from 16.15¢, or gas fell under $1.72 per Mcf from $19.42. A useful quote test for Saginaw: the heat pump is worth it within a decade if it costs less than $3,530 more than replacing the furnace and AC, and within 7 years if the gap is under $2,471.
If your home heats with electric baseboard instead of gas
Plenty of homes in Saginaw heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Saginaw's answer improves. Switching saves about $748 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 13.4 years.
Saginaw against the rest of the country
Ranked against the other 3206 cities covered, Saginaw comes in at 2468 for heating severity, 1 would be the coldest place in the dataset, and 1535 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 Saginaw's figure comes from
The methodology guide walks through exactly how Saginaw's 3.06 seasonal COP and the rest of this page's numbers get built. Saginaw's 15.1°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
