Five months of Laurens summer heat

Your air conditioner in Laurens works May through September, five months a year, with summer afternoons averaging 89°F. That's a long stretch of steady running, and the unit you install now needs to hold up through all of it.

Laurens County has seen its share of hail and wind too, 12 hail events and 59 damaging wind events over the past ten years. An outdoor condenser sits exposed to that. Any new central air conditioner installed today has to meet the federal efficiency minimum of 14.3 SEER2, so whatever goes in will start from that baseline.

What size air conditioner does my house need?
The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated. There's no single answer that fits every home. A contractor works this out with a load calculation, not by guessing from square footage alone. Getting this wrong in either direction costs you. Too small and it runs constantly all summer without keeping up. Too big and it cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy. With summer afternoons here averaging 89°F for five months of the year, getting the size right matters more than it would somewhere milder.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit were installed together, replace them together. Matching a new outdoor unit to an old indoor coil often means the two aren't rated to work as a pair. You lose the efficiency you're paying for. Refrigerant and coil designs have changed enough over the years that many new outdoor units won't pair with an old indoor coil at all. A contractor can tell you whether your existing coil is a match or whether it makes sense to replace both.
Do HVAC contractors in Laurens need a state license to work on my home?
Ask to see a contractor's license before any work starts. A licensed contractor can show you their license number and where it's registered, and you can call the state licensing board to confirm it's active. This protects you if a problem shows up with the work later.
