Will a heat pump pay off in Roma, TX?
The math in Roma isn't close — a heat pump wins outright. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $383 of lower running costs every year, landing the payback clock at roughly 2.6 years. Nothing about that conclusion is generic — it's built entirely from Roma's own numbers.
The climate behind Roma's payback figure
562 heating degree days pile up here every year, so Roma barely has a winter to speak of; the cooling side runs to 4763 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 33.6°F, against a record low of 19°F. That puts the seasonal coefficient of performance at 3.2 for the recommended standard unit. A standard ducted system is enough here; Roma's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, ZAPATA COUNTY AIRPORT, 41.1 miles from Roma.
Roma's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 445 heating kilowatt-hours annually on top of cooling, totalling about $728 a year on electricity. That compares with roughly 6 Mcf a year of gas at Roma's 19.42 per-Mcf rate — about $1,111 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 28.7 years, for a 15-year net position $4,743 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Roma — 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. About $499 a year comes back this way, enough that the 11-year payback clears the $5,500 premium comfortably within the equipment's life.
How Roma compares nationally
Ranked against the other 3206 cities covered, Roma comes in at 3042 for heating severity — 1 would be the coldest place in the dataset — and 2872 by population, where 1 is largest. 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 Roma
About 11,635 people live in Roma, 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.
