Will a heat pump pay off in Homestead, FL?

A heat pump earns back its extra cost in Homestead 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). Homestead's residents would see roughly $333 a year back in running costs, putting the payback around 3 years. The window here is reasonable, and it's specific to what Homestead actually pays for power and gas.

Homestead's weather, in the numbers that matter

Homestead barely has a winter to speak of — 51 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 4751 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 50.5°F, against a record low of 50°F. That puts the seasonal coefficient of performance at 3.7 for the recommended standard unit. Homestead'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, HOMESTEAD AFB AIRPORT, 4.1 miles from Homestead.

The month-to-month numbers for Homestead

Modelled on a typical 2000-square-foot house, the heat pump draws about 35 kWh a year to keep it warm, plus cooling, for a combined electric bill near $630 a year. The gas furnace it replaces burns roughly 1 Mcf a year at 25.48 per Mcf here, for a running cost near $964 a year (electricity here runs 15.43¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 33 years, leaving the 15-year total $3,998 ahead.

The other scenario: no gas furnace to begin with

Gas isn't universal in Homestead — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $340 a year comes back this way, enough that the 16.2-year payback clears the $5,500 premium comfortably within the equipment's life.
