Five months of Forest Park heat, every year
Your air conditioner works from May through September here, with summer afternoons averaging 88°F. That is the stretch it has to get through without a break, year after year.
Any central air conditioner installed new has to meet 14.3 SEER2, the federal efficiency minimum set in 2023. That is the baseline now, not an upgrade you pay extra for.

Georgia requires HVAC contractors to hold a state license.
The Georgia State Construction Industry Licensing Board tests contractors before they can hold this license, and the board keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it travels with them from one installation to the next rather than being issued fresh each time.
For an air conditioner install, that license is what stands behind the person doing the work. In most cities and counties in Georgia, the job also needs a permit from the local building office, with an inspection once it's done, and that inspection is a separate check on the installation itself, not on the contractor.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor works through your insulation, window area, ceiling height, and how much shade your house gets in the afternoon, since summer highs here average 88°F for five months of the year. An oversized unit cools the air fast but shuts off before it pulls the humidity out, and an undersized one runs constantly and still can't keep up. Ask the contractor to walk you through the calculation rather than quote a size off the square footage.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and the indoor side is still in good shape, replacing just the outdoor unit can work. A mismatched system, an old coil paired with a new condenser, often runs less efficiently than either part was built for, and some coils won't pair with newer refrigerant types at all. Age matters too. If the indoor unit is old enough to fail soon after, replacing both at once is worth asking about. A contractor can check whether your existing coil and ductwork will work with a new condenser before you decide.
- Do HVAC contractors in Forest Park need a state license to work on my home?
- Yes. Georgia requires HVAC contractors to hold a state license, issued by the State Construction Industry Licensing Board. Ask to see the license number before work starts, and you can confirm it with the board if you want to be sure.
