Will a heat pump pay off in Rockport, TX?
The math in Rockport isn't close — a heat pump wins outright. $1,000 is what Rockport would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $340 saved annually, for a payback of roughly 2.9 years. That verdict holds specifically for Rockport's own climate and rates, not a national average.
Rockport's weather, in the numbers that matter
493 heating degree days pile up here every year, so Rockport barely has a winter to speak of; the cooling side runs to 4227 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 34°F, against a record low of 24.1°F. That puts the seasonal coefficient of performance at 3.21 for the recommended standard unit. Rockport's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from ROCKPORT, the closest NOAA station, 2.1 miles out.
Rockport's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 389 heating kilowatt-hours annually on top of cooling, totalling about $645 a year on electricity. Rockport's gas rate of 19.42 per Mcf, applied to the 5 Mcf a year the furnace burns, puts its running cost near $984 a year, against 16.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 32.4 years; over 15 years the net position sits $4,094 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Rockport — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Rockport's answer improves. The saving here runs about $441 a year, which recovers the extra $5,500 spent going electric in roughly 12.5 years.
How Rockport compares nationally
Among 3206 cities, Rockport's winter puts it at rank 3061 for severity, while its size puts it at rank 2977 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.
