Five months of Georgia heat, every year
Peachtree Corners homes run the air conditioner May through September, with summer afternoons averaging 87°F. That is the stretch where a unit either keeps up or you find out it can't.
Gwinnett County has also seen 143 damaging wind events and 20 hail events over the past ten years, with hailstones up to 2.5 inches. Whatever goes in outside takes that on. Any new central air conditioner installed today has to meet a federal minimum of 14.3 SEER2, so the baseline efficiency is already set. What's left to decide is sizing it right for a five-month cooling season and setting it where it can hold up outside.

Georgia requires HVAC contractors to hold a state license.
Georgia licenses HVAC contractors through the State Construction Industry Licensing Board. That license belongs to the contractor, not the job, so it was tested and put on record once and it covers this installation the same as any other.
For this job, the license is what stands behind the person doing the work. In most cities and counties, an air conditioner installation also needs a permit from the local building office and an inspection once the work is done, and that inspection is a separate check on the finished job, done by the building office rather than the state board.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have and which way they face, and how many people live in the house. A unit that is too big cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. A unit that is too small runs constantly and still cannot keep up on the hottest afternoons. A contractor works this out with a load calculation on your actual house, not a chart based on square footage alone.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so replacing only one can leave you with a system that runs poorly or wears out early. If your indoor coil is old, mismatched refrigerant and airflow specs between an old coil and a new condenser can cut efficiency and shorten the life of the new equipment. A contractor can check whether your existing coil and ductwork will work with a new outdoor unit, or whether the full system makes more sense. New units also have to meet the current federal minimum of 14.3 SEER2, which is worth knowing if your indoor coil dates back further than that.
- Do HVAC contractors in Peachtree Corners 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 a license number before work starts is a reasonable thing to do, and any licensed contractor should be able to give you one without hesitation.
