Should Dripping Springs switch to a heat pump?
This one's marginal in Dripping Springs: 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 $347 of lower running costs every year, landing the payback clock at roughly 10.1 years. It's a genuine toss-up here — Dripping Springs's numbers don't point clearly either way.
How cold Dripping Springs actually gets
Dripping Springs barely has a winter to speak of — 1136 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3651 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 21.9°F, against a record low of 16°F. That puts the seasonal coefficient of performance at 3.23 for the recommended cold-climate unit. A cold-climate unit is the right call in Dripping Springs — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from AUSTIN-CAMP MABRY, the closest NOAA station, 21.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 891 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $647 a year. That compares with roughly 12 Mcf a year of gas at Dripping Springs's 19.42 per-Mcf rate — about $994 a year — against a local electricity rate of 16.15¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 38.9 years, for a 15-year net position $1,710 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Dripping Springs — 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 $582 a year, which recovers the extra $8,000 spent going electric in roughly 13.7 years.
How Dripping Springs compares nationally
Among 3206 cities, Dripping Springs's winter puts it at rank 2838 for severity, while its size puts it at rank 3164 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.
What to do with this number in Dripping Springs
Dripping Springs, Texas is home to about 10,165 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 Dripping Springs, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Dripping Springs's 3.23 seasonal COP and payback figure. Dripping Springs's 21.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
