Five months of summer heat here works your air conditioner hard
Grovetown needs cooling May through September, five months a year, with summer afternoons averaging 90°F. A new system has to be sized for that whole stretch, not just the hottest day in it.
The outdoor unit sits outside through all of it, and Columbia County has logged 92 damaging wind events and 23 hail events over the past ten years, with hail up to 1.75 inches. Any central air conditioner installed new has to meet the federal minimum of 14.3 SEER2.

Georgia requires HVAC contractors to hold a state license.
That license is tied to the contractor, not to this one job. It is what stands behind whoever does the installation, anywhere in Georgia.
In most cities and counties, including here, replacing an air conditioner needs a permit from the local building office, and an inspection once the work is done. The permit is separate from the license. It is the local building office, not the state board, that checks how this installation was actually done.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor will look at your insulation, your windows, your duct layout, and how much shade your house gets before landing on a number. Bigger isn't better here. An oversized unit cools the air fast but shuts off before it pulls the humidity out of the house, so the air stays damp even after the room feels cool. With summer afternoons here averaging 90°F for five months of the year, getting that balance right matters more than it would somewhere cooler.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if the outdoor unit is failing, the indoor coil should be replaced with it. Manufacturers match the coil and condenser as a set, and pairing a new condenser with an old coil often means it won't hit the efficiency or cooling output it's rated for. Refrigerant type and airflow specs can also differ between old and new components, which limits what the new unit can actually do. A contractor can check the age and condition of your coil and ductwork and tell you whether a full system makes sense for your house.
- Do HVAC contractors in Grovetown 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 verify it through the board. A licensed contractor is trained to size and install the system correctly, which matters for a job like AC installation.
