Five months of Aiken heat, every year
From May through September your air conditioner runs almost every day, working against afternoon highs that average 91°F. That is the stretch that wears down a unit, not the mild months on either side of it.
Aiken County has also logged 185 damaging wind events and 52 hail events over the past ten years, with hail up to 1.75 inches. Whatever goes in outside has to hold up to that. And if it is a new install, it has to meet the federal minimum of 14.3 SEER2, the efficiency standard that applies to every central air conditioner built since 2023.

- What size air conditioner does my house need?
- There's no single number that fits every house, and a bigger unit isn't a safer bet. Sizing depends on your square footage, insulation, window placement, and how much sun your walls take on through those summer afternoons here. A contractor works this out with a load calculation, not a guess based on your old unit's size. Too big and it cools fast but never runs long enough to pull humidity out of the air. Too small and it runs constantly without ever catching up.
- Should I replace the whole system or just the outdoor unit?
- If your indoor and outdoor units are original to each other and one is failing, replacing both is usually the sounder move. The indoor coil and outdoor condenser are matched to work at a specific capacity and efficiency together. Pair a new outdoor unit with an old indoor coil and you can lose efficiency, and some manufacturers won't warranty the mismatch at all. A contractor can check your indoor coil's condition and age against the new unit to tell you whether it's worth keeping.
- Do HVAC contractors in Aiken need a state license to work on my home?
- Yes. South Carolina requires HVAC contractors to hold a state mechanical contractor's license to install or work on residential air conditioning systems. Ask to see the license number before work starts, and you can verify it through the South Carolina Contractor's Licensing Board. This matters more here than it might elsewhere, since a proper install has to hold up against real wind and hail, and licensing is part of what keeps that work accountable.
