Mableton asks a heat pump to work almost year round
Homes here need heat or cooling 11 months of the year. Winter nights average 34°F from December through February, mild enough that a heat pump can carry the heat load on its own most nights. Summer afternoons average 88°F, and the same unit switches over to cooling for May through September.
Most homes in the area still heat with gas, so a new heat pump running a full 6 month winter is doing a job the house wasn't necessarily set up for. Any split system installed new has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum as of 2023. Power loss is also worth planning around. Close to a third of Georgia households went at least 24 hours without power in 2024, and a heat pump that comes back on by itself once power returns matters when the season runs this long.

Georgia requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to the job, so it covers this installation the same as any other job that contractor takes on in the state.
For this job, that license is what stands behind the person doing the work. Beyond that, most cities and counties in Georgia require a permit for a heat pump installation, and an inspector checks the work once it is done. That inspection confirms the installation meets code, separate from whatever the contractor's license already covers.

- Is a heat pump better than a furnace?
- It depends on what you're comparing it to and what you want it to do. A heat pump handles both heating and cooling, so it replaces a furnace and an air conditioner with one system. Here in Mableton, winters are mild enough, with lows averaging 34°F, that a heat pump can carry the heating load on its own for most homes. A furnace only heats, and most homes here already pair one with a separate air conditioner, since 68.2% of homes heat with gas.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of your home. A heat pump does the same thing in summer, but it can also run in reverse and pull heat from outside air into your home in winter. That's why a heat pump can replace both your furnace and your air conditioner, while a straight air conditioner only covers the five months a year you need cooling here.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from outside air even when it's cold, down to well below freezing. Mableton winters average 34°F at night, which is well within the range a heat pump handles without trouble. Federal minimums now require new heat pumps to hit 7.5 HSPF2 for heating efficiency, so a system installed today is built for exactly this kind of winter.
