Heat Pump Payback in Mount Pleasant, TX
Mount Pleasant, TX: the heat pump payback math
In Mount Pleasant, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Mount Pleasant would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $290 saved annually, for a payback of roughly 18.9 years. That's a technicality, not a recommendation, for anyone actually living in Mount Pleasant.

How cold Mount Pleasant actually gets
1994 heating degree days pile up here every year, so Mount Pleasant has a mild winter by US standards; the cooling side runs to 2084 cooling degree days, where summers are hot enough that cooling matters as much as heating. 16.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 8.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.11 on the cold-climate unit fit for this climate. Mild on average, but the occasional cold snap is what sizes the equipment: at a 16.9°F design temperature Mount Pleasant 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. These numbers come from Mount Pleasant Regional Airport, the closest NOAA station, 4.4 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,623 kWh a year to keep it warm, plus cooling, for a combined electric bill near $549 a year. The gas furnace it replaces burns roughly 21 Mcf a year at $19.42 per Mcf here, for a running cost near $839 a year including the old AC (electricity here runs 16.15¢/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 $1,145 behind.
The break-even point in Mount Pleasant
Gas would only overtake the heat pump in Mount Pleasant if electricity rose past 57.7¢/kWh from 16.15¢, or gas fell under $5.44 per Mcf from $19.42. A useful quote test for Mount Pleasant: the heat pump is worth it within a decade if it costs less than $2,900 more than replacing the furnace and AC, and within 7 years if the gap is under $2,030.
The other scenario: no gas furnace to begin with
Plenty of homes in Mount Pleasant heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Mount Pleasant's answer improves. The saving here runs about $702 a year, which recovers the extra $10,000 spent going electric in roughly 14.2 years.
Where Mount Pleasant ranks in this dataset
Mount Pleasant lands at position 2425 out of 3206 cities on heating severity (coldest is 1), and 2273 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.
