Should Tomball switch to a heat pump?
In Tomball, a heat pump pays for itself within a reasonable window. 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). Tomball's residents would see roughly $313 a year back in running costs, putting the payback around 3.2 years. That's a real payback, built from Tomball's own climate and utility rates, not a national guess.
Why Tomball's climate drives this number
961 heating degree days pile up here every year, so Tomball barely has a winter to speak of; the cooling side runs to 3447 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 28.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 17.1°F on file. Worked through the model, that's a seasonal COP of 3.06 on the standard unit fit for this climate. A standard ducted system is enough here; Tomball's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 795 kWh a year to keep it warm, plus cooling, for a combined electric bill near $603 a year. Tomball's gas rate of 19.42 per Mcf, applied to the 10 Mcf a year the furnace burns, puts its running cost near $916 a year, against 16.15¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 35.2 years, leaving the 15-year total $3,691 ahead.
Electric resistance heat in Tomball, compared
Not every home in Tomball has gas service. Swap the comparison to resistance heat instead of gas, and Tomball's answer improves. About $511 a year comes back this way, enough that the 10.8-year payback clears the $5,500 premium comfortably within the equipment's life.
How Tomball compares nationally
Tomball lands at position 2919 out of 3206 cities on heating severity (coldest is 1), and 2375 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.
What to do with this number in Tomball
About 15,152 people live in Tomball, 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.
