Heat pump vs. gas furnace in Richardson, TX
In Richardson, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Richardson's residents would see roughly $361 a year back in running costs, putting the payback around 9.7 years. Whether that's worth it in Richardson depends on how many years you expect to own the place.
The climate behind Richardson's payback figure
Degree days tell the story here: Richardson racks up 1620 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3408 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 18.9°F here (record low 9.5°F), which works out to a seasonal COP of 3.15 for the cold-climate class of unit this climate calls for. Richardson needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from ADDISON AIRPORT, the closest NOAA station, 7.4 miles out.
The month-to-month numbers for Richardson
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,302 kWh a year to keep it warm, plus cooling, for a combined electric bill near $680 a year. Richardson's gas rate of 19.42 per Mcf, applied to the 17 Mcf a year the furnace burns, puts its running cost near $1,041 a year, against 16.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 37.4 years; over 15 years the net position sits $1,920 ahead.
The other scenario: no gas furnace to begin with
Not every home in Richardson has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $696 a year, which recovers the extra $8,000 spent going electric in roughly 11.5 years.
Richardson against the rest of the country
Ranked against the other 3206 cities covered, Richardson comes in at 2645 for heating severity — 1 would be the coldest place in the dataset — and 254 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
