Heat Pump Payback in Waco, TX
Will a heat pump pay off in Waco, TX?
In Waco, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $334 saved annually, for a payback of roughly 16.5 years. That's a technicality, not a recommendation, for anyone actually living in Waco.

Waco's weather, in the numbers that matter
Degree days tell the story here: Waco racks up 1622 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3089 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 16°F here (coldest 2024 reading 12°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. Mild on average, but the occasional cold snap is what sizes the equipment: at a 16°F design temperature Waco falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. Climate figures trace to the nearest NOAA station, Waco Regional Airport, 4.8 miles from Waco.
The yearly running costs in Waco
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,333 kWh a year to keep it warm, plus cooling, for a combined electric bill near $641 a year. The gas furnace it replaces burns roughly 17 Mcf a year at $19.42 per Mcf here, for a running cost near $975 a year including the old AC (electricity here runs 16.15¢/kWh). 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 $492 behind.
How sensitive Waco's result is to prices
In Waco 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 Waco: the heat pump is worth it within a decade if it costs less than $3,340 more than replacing the furnace and AC, and within 7 years if the gap is under $2,338.
If your home heats with electric baseboard instead of gas
Plenty of homes in Waco 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 $669 a year comes back this way, enough that the 14.9-year payback clears the $10,000 premium comfortably within the equipment's life.
Waco against the rest of the country
Among 3206 cities, Waco's winter puts it at rank 2640 for severity, while its size puts it at rank 191 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.
