Heat pump vs. gas furnace in DeSoto, TX
DeSoto sits right on the fence — how long you'll own the house decides this one. $3,500 is what DeSoto would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $338 of lower running costs every year, landing the payback clock at roughly 10.3 years. It's a genuine toss-up here — DeSoto's numbers don't point clearly either way.
How cold DeSoto actually gets
Degree days tell the story here: DeSoto racks up 1726 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3049 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 16°F here (record low 10.4°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. DeSoto needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

The month-to-month numbers for DeSoto
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,419 kWh a year to keep it warm, plus cooling, for a combined electric bill near $649 a year. The gas furnace it replaces burns roughly 18 Mcf a year at 19.42 per Mcf here, for a running cost near $987 a year (electricity here runs 16.15¢/kWh). Buy it outright, not incrementally, and payback stretches to 39.9 years; over 15 years the net position sits $1,574 ahead.
The other scenario: no gas furnace to begin with
Not every home in DeSoto 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. About $695 a year comes back this way, enough that the 11.5-year payback clears the $8,000 premium comfortably within the equipment's life.
DeSoto against the rest of the country
DeSoto lands at position 2573 out of 3206 cities on heating severity (coldest is 1), and 725 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 DeSoto
DeSoto, Texas is home to about 56,711 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 DeSoto, nothing is lost by holding off until the current equipment genuinely fails.
