Is a heat pump worth it in Gonzales?
Gonzales clears a genuine payback here, inside a reasonable stretch of years. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. That premium is recovered through $276 of lower running costs every year, landing the payback clock at roughly 3.6 years. The window here is reasonable, and it's specific to what Gonzales actually pays for power and gas.
Gonzales's weather, in the numbers that matter
Degree days tell the story here: Gonzales racks up 1080 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3325 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 30.2°F, against a record low of 19.2°F. That puts the seasonal coefficient of performance at 3.1 for the recommended standard unit. Gonzales's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

Gonzales's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 882 heating kilowatt-hours annually on top of cooling, totalling about $503 a year on electricity. Gonzales's gas rate of 17.38 per Mcf, applied to the 11 Mcf a year the furnace burns, puts its running cost near $778 a year, against 13.52¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 39.9 years, leaving the 15-year total $3,133 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Gonzales — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $450 a year, which recovers the extra $5,500 spent going electric in roughly 12.2 years.
How Gonzales compares nationally
Ranked against the other 3206 cities covered, Gonzales comes in at 2863 for heating severity — 1 would be the coldest place in the dataset — and 2539 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.
