Is a heat pump worth it in Mont Belvieu?
A heat pump earns back its extra cost in Mont Belvieu within a sensible timeframe. 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). Mont Belvieu's residents would see roughly $300 a year back in running costs, putting the payback around 3.3 years. That's a real payback, built from Mont Belvieu's own climate and utility rates, not a national guess.
Why Mont Belvieu's climate drives this number
Mont Belvieu barely has a winter to speak of — 853 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3321 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 32°F, against a record low of 21.4°F. That puts the seasonal coefficient of performance at 3.15 for the recommended standard unit. A standard ducted system is enough here; Mont Belvieu's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Mont Belvieu
Electricity use for heating alone comes out to about 686 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $568 a year. Mont Belvieu's gas rate of 19.42 per Mcf, applied to the 9 Mcf a year the furnace burns, puts its running cost near $868 a year, against 16.15¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 36.7 years, for a 15-year net position $3,494 ahead.
Electric resistance heat in Mont Belvieu, compared
Plenty of homes in Mont Belvieu heat with electricity alone, no gas line involved. 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 $476 a year, which recovers the extra $5,500 spent going electric in roughly 11.6 years.
Where Mont Belvieu ranks in this dataset
Mont Belvieu lands at position 2950 out of 3206 cities on heating severity (coldest is 1), and 3144 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.
