Will a heat pump pay off in Cutler Bay, FL?

A heat pump earns back its extra cost in Cutler Bay 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). Cutler Bay'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 Cutler Bay actually pays for power and gas.

How cold Cutler Bay actually gets

Cutler Bay 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. Sizing runs off the design temperature, not the average day: 50.5°F here (record low 50°F), which works out to a seasonal COP of 3.7 for the standard class of unit this climate calls for. Cutler Bay's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

Cutler Bay's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 35 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $630 a year. Cutler Bay's gas rate of 25.48 per Mcf, applied to the 1 Mcf a year the furnace burns, puts its running cost near $964 a year, against 15.43¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 33 years; over 15 years the net position sits $3,998 ahead.

If your home heats with electric baseboard instead of gas

Not every home in Cutler Bay has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $340 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 16.2 years.

Cutler Bay against the rest of the country

Cutler Bay lands at position 3190 out of 3206 cities on heating severity (coldest is 1), and 894 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
