Pflugerville, TX: the heat pump payback math
This one's marginal in Pflugerville: 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 $304 of lower running costs every year, landing the payback clock at roughly 11.5 years. Whether that's worth it in Pflugerville depends on how many years you expect to own the place.
Why Pflugerville's climate drives this number
1053 heating degree days pile up here every year, so Pflugerville barely has a winter to speak of; the cooling side runs to 3138 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 21.2°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 15.8°F on file. Worked through the model, that's a seasonal COP of 3.21 on the cold-climate unit fit for this climate. Pflugerville 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. Climate figures trace to the nearest NOAA station, AUSTIN EXECUTIVE AIRPORT, 4.2 miles from Pflugerville.
The month-to-month numbers for Pflugerville
Modelled on a typical 2000-square-foot house, the heat pump draws about 831 kWh a year to keep it warm, plus cooling, for a combined electric bill near $566 a year. The gas furnace it replaces burns roughly 11 Mcf a year at 19.42 per Mcf here, for a running cost near $870 a year (electricity here runs 16.15¢/kWh). Buy it outright, not incrementally, and payback stretches to 44.5 years; over 15 years the net position sits $1,053 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Pflugerville has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $521 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 15.4 years.
How Pflugerville compares nationally
Pflugerville lands at position 2872 out of 3206 cities on heating severity (coldest is 1), and 586 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.

Where Pflugerville's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Pflugerville's 3.21 seasonal COP and payback figure. Pflugerville's 21.2°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.
