Deerfield Beach's weather, in the numbers that matter
Deerfield Beach barely has a winter to speak of, 55 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4842 cooling degree days. Sizing runs off the design temperature, not the average day: 52°F here (coldest 2024 reading 48.9°F), which works out to a seasonal COP of 3.75 for the standard class of unit this climate calls for. Deerfield Beach'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, Pompano Beach Airpark Airport, 4.4 miles from Deerfield Beach.
What it actually costs to run, year to year
On a typical 2000-square-foot house, heating needs here are close to nil, so the heat pump's electric bill, near $643 a year, is almost entirely air conditioning. Heating barely registers here, a gas furnace would burn about 1 Mcf a year at $25.48 per Mcf, so nearly all of the $983 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Deerfield Beach comes from the heat pump being a more efficient air conditioner, not from heating. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,102 ahead.
The break-even point in Deerfield Beach
In Deerfield Beach the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Deerfield Beach: the heat pump is worth it within a decade if it costs less than $3,400 more than replacing the furnace and AC, and within 7 years if the gap is under $2,380.
Electric resistance heat in Deerfield Beach, compared
Plenty of homes in Deerfield Beach heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Deerfield Beach's answer improves. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Deerfield Beach against the rest of the country
Deerfield Beach lands at position 3176 out of 3206 cities on heating severity (coldest is 1), and 392 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.
