Heat Pump Payback in Hammond, LA
Hammond, LA: the heat pump payback math
This one's marginal in Hammond: 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 $3,000. Lower bills claw that back: about $258 saved annually, for a payback of roughly 11.6 years. Whether that's worth it in Hammond depends on how many years you expect to own the place.

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, and the coldest daily reading in the 2024 station record was 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 including the old AC (electricity here runs 13.52¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $877 ahead.
How sensitive Hammond's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Hammond at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $258 a year saved, a difference under $1,806 pays back within 7 years here, and under $2,580 within 10.
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. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
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.

More on how this number was built
Every constant behind this page, the 2.99 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Not every home in Hammond has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
