Heat Pump Payback in Morgan City, LA
Will a heat pump pay off in Morgan City, LA?
In Morgan City, the math is close enough that it comes down to how long you plan to stay. 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 $250 saved annually, for a payback of roughly 12 years. Whether that's worth it in Morgan City depends on how many years you expect to own the place.

Why Morgan City's climate drives this number
925 heating degree days pile up here every year, so Morgan City barely has a winter to speak of; the cooling side runs to 3033 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 33.3°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 21.7°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.19 on the standard unit fit for this climate. A standard ducted system is enough here; Morgan City's design temperature doesn't justify the cold-climate premium.

Morgan City's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 734 kWh a year to keep it warm, plus cooling, for a combined electric bill near $449 a year. The gas furnace it replaces burns roughly 10 Mcf a year at $17.38 per Mcf here, for a running cost near $699 a year including the old AC (electricity here runs 13.52¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $750 ahead.
What would change Morgan City's answer
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 Morgan City at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $250 a year saved, a difference under $1,750 pays back within 7 years here, and under $2,500 within 10.
Electric resistance heat in Morgan City, compared
Plenty of homes in Morgan City heat with electricity alone, no gas line involved. 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.
Morgan City against the rest of the country
Among 3206 cities, Morgan City's winter puts it at rank 2937 for severity, while its size puts it at rank 3025 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.
