Hereford, TX: the heat pump payback math
This one's marginal in Hereford: 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 $3,500 after a $2,000 federal tax credit. That premium is recovered through $361 of lower running costs every year, landing the payback clock at roughly 9.7 years. Whether that's worth it in Hereford depends on how many years you expect to own the place.
Why Hereford's climate drives this number
Hereford has a real but manageable winter — 3283 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1956 cooling degree days. Sizing runs off the design temperature, not the average day: 13.6°F here (record low 1.2°F), which works out to a seasonal COP of 3.03 for the cold-climate class of unit this climate calls for. Hereford needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. Climate figures trace to the nearest NOAA station, HEREFORD MUNICIPAL AIRPORT, 4.3 miles from Hereford.
The month-to-month numbers for Hereford
A 2000-square-foot house here would pull roughly 2,744 heating kilowatt-hours annually on top of cooling, totalling about $712 a year on electricity. The gas furnace it replaces burns roughly 34 Mcf a year at 19.42 per Mcf here, for a running cost near $1,073 a year (electricity here runs 16.15¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 37.4 years, for a 15-year net position $1,915 ahead.
Electric resistance heat in Hereford, compared
Plenty of homes in Hereford heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,040 a year comes back this way, enough that the 7.7-year payback clears the $8,000 premium comfortably within the equipment's life.
Hereford against the rest of the country
Among 3206 cities, Hereford's winter puts it at rank 1829 for severity, while its size puts it at rank 2407 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Hereford
About 14,860 people live in Hereford, Texas, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Hereford's 3.03 seasonal COP and payback figure. At a 13.6°F design temperature, Hereford sits in cold-climate territory; the guide to that class of unit explains why.
