Heat Pump Payback in Thibodaux, LA
Heat pump vs. gas furnace in Thibodaux, LA
Thibodaux sits right on the fence, how long you'll own the house decides this one. 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 $267 saved annually, for a payback of roughly 11.2 years. Whether that's worth it in Thibodaux depends on how many years you expect to own the place.

The climate behind Thibodaux's payback figure
981 heating degree days pile up here every year, so Thibodaux barely has a winter to speak of; the cooling side runs to 3273 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 32°F here (coldest 2024 reading 21.2°F), which works out to a seasonal COP of 3.15 for the standard class of unit this climate calls for. A standard ducted system is enough here; Thibodaux's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 789 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $484 a year. The gas furnace it replaces burns roughly 10 Mcf a year at $17.38 per Mcf here, for a running cost near $751 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 $1,007 ahead.
The break-even point in Thibodaux
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 Thibodaux at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $267 a year saved, a difference under $1,869 pays back within 7 years here, and under $2,670 within 10.
If your home heats with electric baseboard instead of gas
Not every home in Thibodaux has gas service. Swap the comparison to resistance heat instead of gas, and Thibodaux's answer improves. 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.
Thibodaux against the rest of the country
