Is a heat pump worth it in Denton?
This one's marginal in Denton: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $350 of lower running costs every year, landing the payback clock at roughly 10 years. It's a genuine toss-up here — Denton's numbers don't point clearly either way.
How cold Denton actually gets
2081 heating degree days pile up here every year, so Denton has a mild winter by US standards; the cooling side runs to 3023 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 10.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 9°F on file. Worked through the model, that's a seasonal COP of 2.96 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Denton — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, DENTON MUNICIPAL AIRPORT, 3.4 miles from Denton.
The month-to-month numbers for Denton
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,780 kWh a year to keep it warm, plus cooling, for a combined electric bill near $704 a year. Denton's gas rate of 19.42 per Mcf, applied to the 22 Mcf a year the furnace burns, puts its running cost near $1,054 a year, against 16.15¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 38.6 years, leaving the 15-year total $1,748 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Denton — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Denton's answer improves. The saving here runs about $780 a year, which recovers the extra $8,000 spent going electric in roughly 10.3 years.
Where Denton ranks in this dataset
Denton lands at position 2391 out of 3206 cities on heating severity (coldest is 1), and 161 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 Denton, TX
Denton, Texas is home to about 165,998 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 Denton, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
The methodology guide walks through exactly how Denton's 2.96 seasonal COP and the rest of this page's numbers get built. Denton's 10.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
