Will a heat pump pay off in Weslaco, TX?
Weslaco is a clear case: a heat pump beats what you have by a wide margin. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $357 saved annually, for a payback of roughly 2.8 years. That verdict holds specifically for Weslaco's own climate and rates, not a national average.
Weslaco's weather, in the numbers that matter
Weslaco barely has a winter to speak of — 327 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 4622 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 39.2°F, against a record low of 24.6°F. That puts the seasonal coefficient of performance at 3.37 for the recommended standard unit. Weslaco's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, MID VALLEY AIRPORT, 1.5 miles from Weslaco.
The month-to-month numbers for Weslaco
A 2000-square-foot house here would pull roughly 246 heating kilowatt-hours annually on top of cooling, totalling about $676 a year on electricity. Weslaco's gas rate of 19.42 per Mcf, applied to the 3 Mcf a year the furnace burns, puts its running cost near $1,034 a year, against 16.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 30.8 years; over 15 years the net position sits $4,361 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Weslaco — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Weslaco's answer improves. The saving here runs about $425 a year, which recovers the extra $5,500 spent going electric in roughly 12.9 years.
How Weslaco compares nationally
