Six months of real heat, every year

Georgetown County homes run their air conditioners May through October, six months a year. Summer afternoons average 89°F, and that's the average, not the peak day. A new system here has to hold up through a long, hot stretch, not just a few weeks.

Any central air conditioner installed new has to meet 14.3 SEER2, the federal minimum for units built since 2023. That's the floor a system has to clear. With six months of cooling ahead of it every year, it's worth knowing what your installer is putting in and whether it sits above that minimum.

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, so there's no single number that fits every home. A contractor works this out with a load calculation, not a chart based on square footage alone. Getting this wrong matters here especially, since your system will run for six months straight from May through October. Too big and it cools the air fast but leaves the place feeling damp, too small and it will run flat out on those 89 degree afternoons and still fall behind.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or different efficiency ratings, replacing just the outdoor unit can cause real problems. The two are matched at the factory to work together, and pairing an old coil with a new condenser often means the system never reaches the cooling capacity or efficiency it's rated for. Refrigerant type is another issue, since older systems used a refrigerant that's been phased out. A contractor can check what you have and tell you whether the coil is compatible or whether the whole system needs to go at once.
Do HVAC contractors in Georgetown need a state license to work on my home?
Ask to see a contractor's license before any work starts, and confirm it covers the job you need done. A licensed contractor is who you want handling a new installation, since they're the one who can size the system correctly and make sure it meets the current federal efficiency minimum of 14.3 SEER2.
