Two months of real heat, but it still counts
Cooling season in Lewisburg only runs July and August, with afternoons averaging 79°F. That is a short stretch, but it is also the stretch where a weak or failing unit gets found out fast, right when you need it most.
Greenbrier County has seen its share of rough weather too, with 104 damaging wind events and 9 hail storms over the past ten years, one dropping hail 1.75 inches across. Whatever gets installed outside your home has to be able to take that. And if you're putting in a new central air conditioner, it has to meet the federal efficiency minimum of 13.4 SEER2.

West Virginia requires HVAC contractors to hold a state license.
The license is issued by the state's Commissioner of Labor, and it covers the contractor rather than each job they take on. Once a contractor holds it, that license is what stands behind any job they take, this one included.
For an air conditioner installation, the license is not the only check on the job. In most cities and counties in West Virginia, installing a new air conditioner needs a permit from the local building office, and the finished work gets inspected before it is signed off.

- What size air conditioner does my house need?
- There is no single answer without a load calculation done on your actual house. A contractor measures your square footage, insulation, window area and layout, then runs that through a formula to find the right tonnage. Going by square footage alone leads to a unit that is too big or too small, and an oversized system cools the air fast but shuts off before it pulls the humidity down, so the house feels damp even at the right temperature.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing only the outdoor unit usually causes problems. The coil and the condenser are matched to work together, and pairing an old coil with a new condenser can mean the system never reaches its rated efficiency, and sometimes voids the warranty on the new part. A contractor can check whether your existing coil and refrigerant lines are a match for a new outdoor unit before you decide.
- Do HVAC contractors in Lewisburg need a state license to work on my home?
- Yes. West Virginia requires HVAC contractors to hold a state license, issued through the Commissioner of Labor, and that license covers the contractor rather than each individual job. Installing an air conditioner also typically needs a permit from the local building office, with an inspection once the work is finished.
