Should Opelousas switch to a heat pump?
A heat pump earns back its extra cost in Opelousas 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. Opelousas's residents would see roughly $253 a year back in running costs, putting the payback around 3.9 years. The window here is reasonable, and it's specific to what Opelousas actually pays for power and gas.
How cold Opelousas actually gets
Degree days tell the story here: Opelousas racks up 1430 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2657 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 25.7°F, against a record low of 14.7°F. That puts the seasonal coefficient of performance at 2.97 for the recommended standard unit. Opelousas's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from ST LANDRY PARISH AIRPORT AHAR, the closest NOAA station, 2.5 miles out.
The month-to-month numbers for Opelousas
Electricity use for heating alone comes out to about 1,219 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $471 a year. That compares with roughly 15 Mcf a year of gas at Opelousas's 17.38 per-Mcf rate — about $724 a year — against a local electricity rate of 13.52¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 43.4 years, for a 15-year net position $2,799 ahead.
Electric resistance heat in Opelousas, compared
Plenty of homes in Opelousas 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. About $484 a year comes back this way, enough that the 11.4-year payback clears the $5,500 premium comfortably within the equipment's life.
