Is a heat pump worth it in Buford?
In Buford, 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. Buford's residents would see roughly $331 a year back in running costs, putting the payback around 10.6 years. It's a genuine toss-up here — Buford's numbers don't point clearly either way.
How cold Buford actually gets
2526 heating degree days pile up here every year, so Buford has a mild winter by US standards; the cooling side runs to 1755 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 10.9°F here (record low 10.9°F), which works out to a seasonal COP of 2.96 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Buford — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 2,161 heating kilowatt-hours annually on top of cooling, totalling about $545 a year on electricity. The gas furnace it replaces burns roughly 26 Mcf a year at 20.42 per Mcf here, for a running cost near $876 a year (electricity here runs 14.90¢/kWh). Buy it outright, not incrementally, and payback stretches to 40.8 years; over 15 years the net position sits $1,468 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Buford has gas service. Swap the comparison to resistance heat instead of gas, and Buford's answer improves. The saving here runs about $747 a year, which recovers the extra $8,000 spent going electric in roughly 10.7 years.
Buford against the rest of the country
Ranked against the other 3206 cities covered, Buford comes in at 2158 for heating severity — 1 would be the coldest place in the dataset — and 2040 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.
What to do with this number in Buford
Buford, Georgia is home to about 18,642 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Buford, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 2.96 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Buford's 10.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
