Is a heat pump worth it in Clarkston?
This one's marginal in Clarkston: it only clears if you stay long enough. 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. Lower bills claw that back: about $344 saved annually, for a payback of roughly 10.2 years. Whether that's worth it in Clarkston depends on how many years you expect to own the place.
The climate behind Clarkston's payback figure
Clarkston has a mild winter by US standards — 2569 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1846 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 12°F, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Clarkston sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from DEKALB-PEACHTREE AIRPORT, the closest NOAA station, 5.5 miles out.
Clarkston's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,176 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $559 a year. Clarkston's gas rate of 20.42 per Mcf, applied to the 27 Mcf a year the furnace burns, puts its running cost near $903 a year, against 14.90¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 39.2 years, for a 15-year net position $1,662 ahead.
Electric resistance heat in Clarkston, compared
Not every home in Clarkston has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $767 a year comes back this way, enough that the 10.4-year payback clears the $8,000 premium comfortably within the equipment's life.
How Clarkston compares nationally
