HeatPumpPayback

Hammond, LA: the heat pump payback math

A heat pump earns back its extra cost in Hammond within a sensible timeframe. 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. Lower bills claw that back: about $258 saved annually, for a payback of roughly 3.9 years. That's a real payback, built from Hammond's own climate and utility rates, not a national guess.

Why Hammond's climate drives this number

1363 heating degree days pile up here every year, so Hammond barely has a winter to speak of; the cooling side runs to 2799 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 26.6°F, against a record low of 15.6°F. That puts the seasonal coefficient of performance at 2.99 for the recommended standard unit. A standard ducted system is enough here; Hammond's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, HAMMOND MUNICIPAL AIRPORT, 2.5 miles from Hammond.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 1,154 heating kilowatt-hours annually on top of cooling, totalling about $479 a year on electricity. The gas furnace it replaces burns roughly 14 Mcf a year at 17.38 per Mcf here, for a running cost near $737 a year (electricity here runs 13.52¢/kWh). Buy it outright, not incrementally, and payback stretches to 42.6 years; over 15 years the net position sits $2,877 ahead.

Electric resistance heat in Hammond, compared

Gas isn't universal in Hammond — 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 $478 a year, which recovers the extra $5,500 spent going electric in roughly 11.5 years.

Hammond against the rest of the country

Ranked against the other 3206 cities covered, Hammond comes in at 2744 for heating severity — 1 would be the coldest place in the dataset — and 1693 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.

Deciding what's next in Hammond, LA

About 23,426 people live in Hammond, Louisiana, 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, it's worth getting quotes before your current system fails, not after.
