Why Flower Mound's climate drives this number
1667 heating degree days pile up here every year, so Flower Mound has a mild winter by US standards; the cooling side runs to 3318 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 12.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 10.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.01 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 12.9°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Flower Mound. Climate figures trace to the nearest NOAA station, Dallas/Ft Worth International, 11.1 miles from Flower Mound.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,402 heating kilowatt-hours annually on top of cooling, totalling about $683 a year on electricity. Flower Mound's gas rate of $19.42 per Mcf, applied to the 17 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,032 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 $276 behind.
How sensitive Flower Mound's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Flower Mound at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $348 a year saved, a difference under $2,436 pays back within 7 years here, and under $3,480 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Flower Mound heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $693 a year, which recovers the extra $10,000 spent going electric in roughly 14.4 years.
Flower Mound against the rest of the country
Among 3206 cities, Flower Mound's winter puts it at rank 2609 for severity, while its size puts it at rank 463 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
