Heat Pump Payback in Groves, TX
Groves, TX: the heat pump payback math
This one's marginal in Groves: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $301 saved annually, for a payback of roughly 10 years. It's a genuine toss-up here, Groves's numbers don't point clearly either way.

How cold Groves actually gets
871 heating degree days pile up here every year, so Groves barely has a winter to speak of; the cooling side runs to 3316 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 32.2°F here (coldest 2024 reading 21.9°F), which works out to a seasonal COP of 3.16 for the standard class of unit this climate calls for. Groves's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Climate figures trace to the nearest NOAA station, Port Arthur, 5.5 miles from Groves.
Groves's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 698 kWh a year to keep it warm, plus cooling, for a combined electric bill near $569 a year. Groves's gas rate of $19.42 per Mcf, applied to the 9 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $870 a year, against 16.15¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,513 ahead.
What would change Groves's answer
In Groves the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Groves: the heat pump is worth it within a decade if it costs less than $3,010 more than replacing the furnace and AC, and within 7 years if the gap is under $2,107.
The other scenario: no gas furnace to begin with
Gas isn't universal in Groves, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Groves's answer improves. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
How Groves compares nationally
Among 3206 cities, Groves's winter puts it at rank 2942 for severity, while its size puts it at rank 2207 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.
Deciding what's next in Groves, TX
Groves, Texas is home to about 16,866 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 Groves, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
Where Groves's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Groves's 3.16 seasonal COP and payback figure. Homes in Groves without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
