Will a heat pump pay off in Schertz, TX?
The math in Schertz isn't close — a heat pump wins outright. $1,000 is what Schertz would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $336 saved annually, for a payback of roughly 3 years. Nothing about that conclusion is generic — it's built entirely from Schertz's own numbers.
The climate behind Schertz's payback figure
Degree days tell the story here: Schertz racks up 1011 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3754 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 27.3°F, against a record low of 16.2°F. That puts the seasonal coefficient of performance at 3.01 for the recommended standard unit. A standard ducted system is enough here; Schertz's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, RANDOLPH AFB AIRPORT, 2.2 miles from Schertz.
Schertz's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 850 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $654 a year. That compares with roughly 11 Mcf a year of gas at Schertz's 19.42 per-Mcf rate — about $990 a year — against a local electricity rate of 16.15¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 32.7 years, leaving the 15-year total $4,039 ahead.
Electric resistance heat in Schertz, compared
Not every home in Schertz has gas service. 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 $545 a year, which recovers the extra $5,500 spent going electric in roughly 10.1 years.
Where Schertz ranks in this dataset
Schertz lands at position 2903 out of 3206 cities on heating severity (coldest is 1), and 929 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.

About 44,428 people live in Schertz, Texas, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.
Ask a local HVAC contractor for a quote before committing either way.
