Six months of Goose Creek heat is hard on a new system
From May through October your air conditioner is the thing standing between you and a 91°F afternoon. That is six months of long run times a year, not just a few weeks of hard use.
Any central air conditioner installed new here has to meet a federal minimum of 14.3 SEER2. That is the floor, not a feature, so it is worth asking what size and efficiency actually fit your house rather than just what clears the minimum.

- What size air conditioner does my house need?
- It depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated. A unit that's too big cools the air fast but shuts off before it pulls the humidity down, so the house feels damp. One that's too small runs constantly and still can't keep up on a 91 degree afternoon. A contractor will run a load calculation on your actual house rather than guess from a chart.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both the outdoor unit and the indoor coil together. They're matched to work at a specific efficiency, and pairing a new outdoor unit with an old indoor coil usually means you lose the efficiency you paid for, sometimes voids the warranty, and can also cause the compressor to wear out early. If your indoor coil is only a few years old and still in good shape, a contractor can check whether it's compatible with the new unit before deciding.
- Do HVAC contractors in Goose Creek need a state license to work on my home?
- Yes. HVAC work involves refrigerant, gas lines, and electrical connections, so it falls under licensing requirements rather than being left to whoever shows up with a truck. Ask to see a license number before work starts. A contractor who is properly licensed can also tell you what a new AC installation needs to pass inspection.
