Heat Pump Payback in Brandon, MS
Should Brandon switch to a heat pump?
Brandon technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Brandon would pay extra to go electric rather than replace the furnace and AC with the same again. Brandon's residents would see roughly $272 a year back in running costs, putting the payback around 20.2 years. That's a technicality, not a recommendation, for anyone actually living in Brandon.

Brandon's weather, in the numbers that matter
Degree days tell the story here: Brandon racks up 1686 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2732 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 20.1°F, and the coldest daily reading in the 2024 station record was 10.9°F. That puts the seasonal coefficient of performance at 3.18 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 20.1°F design temperature Brandon falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe.

The yearly running costs in Brandon
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,343 kWh a year to keep it warm, plus cooling, for a combined electric bill near $568 a year. That compares with roughly 18 Mcf a year of gas at Brandon's $16.64 per-Mcf rate, about $840 a year with the old AC included, against a local electricity rate of 15.47¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,422 behind.
The break-even point in Brandon
Gas would only overtake the heat pump in Brandon if electricity rose past 222.7¢/kWh from 15.47¢, or gas fell under $1.16 per Mcf from $16.64. A useful quote test for Brandon: the heat pump is worth it within a decade if it costs less than $2,720 more than replacing the furnace and AC, and within 7 years if the gap is under $1,904.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Brandon, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Brandon's answer improves. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Brandon ranks in this dataset
Brandon lands at position 2591 out of 3206 cities on heating severity (coldest is 1), and 1548 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.
Deciding what's next in Brandon, MS
Brandon, Mississippi is home to about 25,870 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Brandon, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
