Five months of Douglasville heat, every year
Summer afternoons here average 88°F, and a new system runs on those days from May through September. That is the stretch it has to handle without a break.
If you're installing new, any central air conditioner made since 2023 has to meet 14.3 SEER2, the federal efficiency minimum. Worth asking what the installer is putting in and where it lands against that number.

Georgia requires HVAC contractors to hold a state license.
Georgia's license comes from the State Construction Industry Licensing Board, and it means the board tested this contractor before letting them hold it. The license covers the contractor, not the job in front of them. It stays with them from one installation to the next, and the board keeps a record of who holds it.
For this installation, that license is what stands behind the work. The board tested and licensed the contractor doing it. On top of that, most cities and counties in Georgia require a permit for an air conditioner installation and an inspection once the work is done, so this particular job gets checked separately from the license itself.

- What size air conditioner does my house need?
- There's no single number that fits every house. It depends on your square footage, how many windows you have, which way they face, how much insulation is in your attic and walls, and your ceiling height. A contractor works this out with a load calculation, not a guess based on your old unit's size. Putting in one that's too big or too small both cause problems, so this step matters more than picking a brand.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing just the outdoor unit often doesn't work well. The coil and condenser are matched to run together, and pairing an old coil with a new condenser can mean the system never hits the efficiency or cooling capacity it's rated for. A contractor can check whether your existing coil will pair with a new outdoor unit. If your system is old enough that the outdoor unit is failing, the indoor coil is usually close behind it.
- Do HVAC contractors in Douglasville 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 it before work starts. This covers installation and repair work on your home's heating and cooling systems, not just new construction.
