Heat pump vs. gas furnace in College Park, GA

This one's marginal in College Park: it only clears if you stay long enough. $3,500 is what College Park would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $339 of lower running costs every year, landing the payback clock at roughly 10.3 years. It's a genuine toss-up here — College Park's numbers don't point clearly either way.

How cold College Park actually gets

College Park has a mild winter by US standards — 2093 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2333 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 14°F, against a record low of 12.9°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, College Park sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, HARTSFIELD-JACKSON ATLANTA IN, 1.5 miles from College Park.

The month-to-month numbers for College Park

Electricity use for heating alone comes out to about 1,743 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $556 a year. The gas furnace it replaces burns roughly 22 Mcf a year at 20.42 per Mcf here, for a running cost near $896 a year (electricity here runs 14.90¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 39.8 years, leaving the 15-year total $1,592 ahead.

The other scenario: no gas furnace to begin with

Not every home in College Park has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $684 a year, which recovers the extra $8,000 spent going electric in roughly 11.7 years.

How College Park compares nationally

College Park lands at position 2388 out of 3206 cities on heating severity (coldest is 1), and 2519 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

College Park, Georgia is home to about 13,953 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 College Park, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page — the 3.04 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. College Park's 14°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.
