Heat Pump Payback in El Campo, TX
Should El Campo switch to a heat pump?
The payback math works in El Campo on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $268 of lower running costs every year, landing the payback clock at roughly 20.5 years. That's a technicality, not a recommendation, for anyone actually living in El Campo.

El Campo's weather, in the numbers that matter
953 heating degree days pile up here every year, so El Campo barely has a winter to speak of; the cooling side runs to 2780 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 19°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 12.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. Mild on average, but the occasional cold snap is what sizes the equipment: at a 19°F design temperature El Campo 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 Wharton Regional Airport, the closest NOAA station, 16.6 miles out.
El Campo's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 764 heating kilowatt-hours annually on top of cooling, totalling about $506 a year on electricity. The gas furnace it replaces burns roughly 10 Mcf a year at $19.42 per Mcf here, for a running cost near $775 a year including the old AC (electricity here runs 16.15¢/kWh). 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 $1,473 behind.
What would change El Campo's answer
In El Campo 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 El Campo: the heat pump is worth it within a decade if it costs less than $2,680 more than replacing the furnace and AC, and within 7 years if the gap is under $1,876.
The other scenario: no gas furnace to begin with
Not every home in El Campo has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
El Campo against the rest of the country
El Campo lands at position 2925 out of 3206 cities on heating severity (coldest is 1), and 2786 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.
What to do with this number in El Campo
El Campo, Texas is home to about 12,176 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 El Campo, nothing is lost by holding off until the current equipment genuinely fails.

Where El Campo's figure comes from
Every constant behind this page, the 3.16 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. At a 19°F design temperature, El Campo sits in cold-climate territory; the guide to that class of unit explains why.
