Leander, TX: the heat pump payback math

This one's marginal in Leander: 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). Lower bills claw that back: about $275 saved annually, for a payback of roughly 12.7 years. Whether that's worth it in Leander depends on how many years you expect to own the place.

The climate behind Leander's payback figure

Degree days tell the story here: Leander racks up 1132 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2687 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 19°F, against a record low of 14.5°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Leander 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. These numbers come from LAGO VISTA RUSTY ALLEN AIRPOR, the closest NOAA station, 8.1 miles out.

The month-to-month numbers for Leander

Modelled on a typical 2000-square-foot house, the heat pump draws about 907 kWh a year to keep it warm, plus cooling, for a combined electric bill near $516 a year. The gas furnace it replaces burns roughly 12 Mcf a year at 19.42 per Mcf here, for a running cost near $791 a year (electricity here runs 16.15¢/kWh). Buy it outright, not incrementally, and payback stretches to 49.1 years; over 15 years the net position sits $623 ahead.

Electric resistance heat in Leander, compared

Gas isn't universal in Leander — many houses run on electric heat already. 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 $509 a year, which recovers the extra $8,000 spent going electric in roughly 15.7 years.

Where Leander ranks in this dataset

Among 3206 cities, Leander's winter puts it at rank 2839 for severity, while its size puts it at rank 409 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.

More on how this number was built

Every constant behind this page — the 3.16 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Leander's 19°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
