Heat pump vs. gas furnace in New Iberia, LA
A heat pump earns back its extra cost in New Iberia within a sensible timeframe. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $262 of lower running costs every year, landing the payback clock at roughly 3.8 years. The window here is reasonable, and it's specific to what New Iberia actually pays for power and gas.
New Iberia's weather, in the numbers that matter
New Iberia barely has a winter to speak of — 1149 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3051 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 28.9°F, against a record low of 18°F. That puts the seasonal coefficient of performance at 3.06 for the recommended standard unit. New Iberia's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, ACADIANA REGIONAL AIRPORT, 4.4 miles from New Iberia.
New Iberia's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 951 kWh a year to keep it warm, plus cooling, for a combined electric bill near $480 a year. The gas furnace it replaces burns roughly 12 Mcf a year at 17.38 per Mcf here, for a running cost near $743 a year (electricity here runs 13.52¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 41.9 years, leaving the 15-year total $2,935 ahead.
Electric resistance heat in New Iberia, compared
Not every home in New Iberia has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $448 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 12.3 years.
How New Iberia compares nationally
Ranked against the other 3206 cities covered, New Iberia comes in at 2834 for heating severity — 1 would be the coldest place in the dataset — and 1487 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.
