Five months of Georgia heat, every year
Your air conditioner works from May through September here, with summer afternoons averaging 88°F. That is five straight months of running most days, and the unit you install this year needs to hold up to all of them.
Paulding County also sees its share of hail and wind. Ten years of storm records show 7 hail events and 125 damaging wind events, so the outdoor unit needs to be installed and positioned with that in mind. If your new system is built after 2023, it has to meet the federal minimum of 14.3 SEER2, so it starts out more efficient than what it may be replacing.

Georgia requires HVAC contractors to hold a state license.
Georgia licenses HVAC contractors through the State Construction Industry Licensing Board. The license is held by the contractor, not issued job by job, so the board has tested and keeps a record of whoever is licensed to do the work, not just this one install.
For an air conditioner installation, that license is what stands behind the work. In most cities and counties, the job will also need a permit from the local building office, with an inspection once the installation is done. That inspection is separate from the license. It is the local check that the unit was put in correctly.

- What size air conditioner does my house need?
- The right size depends on your home, not a rule of thumb. A contractor works this out with a load calculation that accounts for your square footage, insulation, windows, and duct layout, not just square footage alone. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy. An undersized one runs constantly and still can't keep up on the hottest days. Summer afternoons here average 88°F, so getting this number right matters more in a place with five months of real cooling load than somewhere with a short season.
- Should I replace the whole system or just the outdoor unit?
- In most cases, both the outdoor unit and the indoor coil should be replaced together, not just the outdoor unit alone. The two are matched to work at a specific efficiency and capacity, and pairing a new condenser with an old coil usually means you lose the efficiency gain you're paying for, and can shorten the life of the new equipment. If your furnace and ductwork are still in good shape, those often don't need to be touched. A contractor can look at the age and condition of what you have and tell you what actually needs to change.
- Do HVAC contractors in Dallas 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. Before work starts, ask to see the license and confirm it's current. This matters most on a new install, since a licensed contractor is the one accountable if the work doesn't meet code.
