Deer Park, TX: the heat pump payback math
Deer Park 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 $314 of lower running costs every year, landing the payback clock at roughly 3.2 years. That's a real payback, built from Deer Park's own climate and utility rates, not a national guess.
The climate behind Deer Park's payback figure
806 heating degree days pile up here every year, so Deer Park barely has a winter to speak of; the cooling side runs to 3571 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°F here (record low 19.4°F), which works out to a seasonal COP of 3.15 for the standard class of unit this climate calls for. A standard ducted system is enough here; Deer Park's design temperature doesn't justify the cold-climate premium. These numbers come from ELLINGTON FIELD AIRPORT, the closest NOAA station, 6 miles out.
The month-to-month numbers for Deer Park
A 2000-square-foot house here would pull roughly 648 heating kilowatt-hours annually on top of cooling, totalling about $596 a year on electricity. That compares with roughly 8 Mcf a year of gas at Deer Park's 19.42 per-Mcf rate — about $910 a year — against a local electricity rate of 16.15¢/kWh. Buy it outright, not incrementally, and payback stretches to 35 years; over 15 years the net position sits $3,711 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Deer Park heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $481 a year comes back this way, enough that the 11.4-year payback clears the $5,500 premium comfortably within the equipment's life.
