Heat Pump Payback in Mountain Home, AR
Heat pump vs. gas furnace in Mountain Home, AR
Mountain Home technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Mountain Home's residents would see roughly $336 a year back in running costs, putting the payback around 16.4 years. That's a technicality, not a recommendation, for anyone actually living in Mountain Home.

Mountain Home's weather, in the numbers that matter
Degree days tell the story here: Mountain Home racks up 3169 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1565 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 1°F here (coldest 2024 reading -2°F), which works out to a seasonal COP of 2.72 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Mountain Home, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, Ozark Regional Airport, 5.3 miles from Mountain Home.
Mountain Home's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,950 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $569 a year. The gas furnace it replaces burns roughly 33 Mcf a year at $19.25 per Mcf here, for a running cost near $905 a year including the old AC (electricity here runs 13.28¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $465 behind.
How sensitive Mountain Home's result is to prices
Gas would only overtake the heat pump in Mountain Home if electricity rose past 28.2¢/kWh from 13.28¢, or gas fell under $9.08 per Mcf from $19.25. A useful quote test for Mountain Home: the heat pump is worth it within a decade if it costs less than $3,360 more than replacing the furnace and AC, and within 7 years if the gap is under $2,352.
If your home heats with electric baseboard instead of gas
Not every home in Mountain Home has gas service. Swap the comparison to resistance heat instead of gas, and Mountain Home's answer improves. The saving here runs about $766 a year, which recovers the extra $10,000 spent going electric in roughly 13.1 years.
Where Mountain Home ranks in this dataset
