Heat Pump Payback in Conroe, TX
Heat pump vs. gas furnace in Conroe, TX
This one's marginal in Conroe: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $295 saved annually, for a payback of roughly 10.2 years. It's a genuine toss-up here, Conroe's numbers don't point clearly either way.

Conroe's weather, in the numbers that matter
Conroe barely has a winter to speak of, 1303 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2965 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 25°F, and the coldest daily reading in the 2024 station record was 14°F. That puts the seasonal coefficient of performance at 2.95 for the recommended standard unit. Conroe's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,118 kWh a year to keep it warm, plus cooling, for a combined electric bill near $589 a year. Conroe's gas rate of $19.42 per Mcf, applied to the 14 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $884 a year, against 16.15¢ 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 $1,428 ahead.
What would change Conroe's answer
In Conroe 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 Conroe: the heat pump is worth it within a decade if it costs less than $2,950 more than replacing the furnace and AC, and within 7 years if the gap is under $2,065.
Electric resistance heat in Conroe, compared
Plenty of homes in Conroe heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $565 a year comes back this way, enough that the 13.3-year payback clears the $7,500 premium comfortably within the equipment's life.
How Conroe compares nationally
