The climate behind Plant City's payback figure
508 heating degree days pile up here every year, so Plant City barely has a winter to speak of; the cooling side runs to 3528 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 39.2°F here (coldest 2024 reading 33.8°F), which works out to a seasonal COP of 3.37 for the standard class of unit this climate calls for. A standard ducted system is enough here; Plant City's design temperature doesn't justify the cold-climate premium.

The yearly running costs in Plant City
Modelled on a typical 2000-square-foot house, the heat pump draws about 382 kWh a year to keep it warm, plus cooling, for a combined electric bill near $523 a year. Plant City's gas rate of $25.48 per Mcf, applied to the 5 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $840 a year, against 15.43¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,759 ahead.
The break-even point in Plant City
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 Plant City at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $317 a year saved, a difference under $2,219 pays back within 7 years here, and under $3,170 within 10.
Electric resistance heat in Plant City, compared
Gas isn't universal in Plant City, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Plant City's answer improves. 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.
How Plant City compares nationally
