Five months of real heat, every year
Carroll County runs its air conditioners from May through September, five months a year. Summer afternoons average 88°F, and that heat is steady enough that a new system needs to be sized right for the house it's cooling, not just installed and left to run.
The outdoor unit also has to sit through the weather here. The county has logged 87 damaging wind events and 7 hail events over the past ten years, with hailstones up to 1.75 inches. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 14.3 SEER2.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board tests and licenses HVAC contractors before they can take on work like this. That license belongs to the contractor, not to any one job, so it travels with them from house to house rather than getting issued fresh each time.
That license is what stands behind the person installing the air conditioner. The job itself still needs a permit from the local building office, and an inspection once the installation is done, the same as it would in most cities and counties in Georgia.

- What size air conditioner does my house need?
- The right size depends on your square footage, ceiling height, insulation, window count, and how much shade your house gets, not just a rule of thumb per square foot. A contractor works this out with a load calculation, checking your home room by room instead of guessing off a chart. An undersized unit will run constantly and never quite catch up, especially on the 88 degree afternoons here. An oversized one cools too fast, shuts off before it pulls the moisture out of the air, and leaves rooms feeling damp.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both together. The outdoor condenser and the indoor coil are matched to work at a specific efficiency. Pair a new condenser with an old coil and you usually lose the efficiency gain you're paying for. Older systems also run on R-22 refrigerant, and new condensers aren't built to run on it. A contractor can check your existing coil and refrigerant to tell you whether a partial swap is even possible on your system.
- Do HVAC contractors in Carrollton 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. Asking to see that license before work starts is a fair question to ask any contractor.
