Hialeah Gardens, FL: the heat pump payback math
Hialeah Gardens is a clear case: a heat pump beats what you have by a wide margin. 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. That premium is recovered through $335 of lower running costs every year, landing the payback clock at roughly 3 years. Nothing about that conclusion is generic — it's built entirely from Hialeah Gardens's own numbers.
Why Hialeah Gardens's climate drives this number
Degree days tell the story here: Hialeah Gardens racks up 60 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4759 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 51.1°F, against a record low of 48.9°F. That puts the seasonal coefficient of performance at 3.72 for the recommended standard unit. A standard ducted system is enough here; Hialeah Gardens's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 41 heating kilowatt-hours annually on top of cooling, totalling about $632 a year on electricity. The gas furnace it replaces burns roughly 1 Mcf a year at 25.48 per Mcf here, for a running cost near $968 a year (electricity here runs 15.43¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 32.8 years, leaving the 15-year total $4,028 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Hialeah Gardens — 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 $343 a year comes back this way, enough that the 16-year payback clears the $5,500 premium comfortably within the equipment's life.
How Hialeah Gardens compares nationally
Ranked against the other 3206 cities covered, Hialeah Gardens comes in at 3169 for heating severity — 1 would be the coldest place in the dataset — and 1696 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.
