Sugar Land, TX: the heat pump payback math
Sugar Land clears a genuine payback here, inside a reasonable stretch of years. 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 $326 of lower running costs every year, landing the payback clock at roughly 3.1 years. The window here is reasonable, and it's specific to what Sugar Land actually pays for power and gas.
How cold Sugar Land actually gets
834 heating degree days pile up here every year, so Sugar Land barely has a winter to speak of; the cooling side runs to 3725 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: 30.9°F here (record low 18°F), which works out to a seasonal COP of 3.12 for the standard class of unit this climate calls for. Sugar Land's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

Sugar Land's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 677 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $622 a year. The gas furnace it replaces burns roughly 9 Mcf a year at 19.42 per Mcf here, for a running cost near $948 a year (electricity here runs 16.15¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 33.7 years, leaving the 15-year total $3,891 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Sugar Land 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 $498 a year, which recovers the extra $5,500 spent going electric in roughly 11 years.
How Sugar Land compares nationally
Sugar Land lands at position 2955 out of 3206 cities on heating severity (coldest is 1), and 294 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.
