Three months of real heat, then it shuts down
Martinsburg summers run June through August, three months of afternoons averaging 85°F. That is a short season, but a new air conditioner still has to be sized for those afternoons, not just an easier day.
Berkeley County has also logged 25 hail events and 90 damaging wind events over the past ten years, with hail up to 1.5 inches. The outdoor unit sits through all of that, so where it goes and how it is mounted matters. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

West Virginia requires HVAC contractors to hold a state license.
West Virginia tests contractors before it licenses them, and the state keeps a record of who holds that license. The license belongs to the contractor, not to any single job, so it tells you the person or company has already met the state's bar before they ever step into your house.
For this installation, that license is what stands behind the work itself. In most cities and counties, the job also needs a permit from the local building office, with an inspection once the air conditioner is in. That inspection, where it applies, is a separate check done by the city or county rather than the state, and it looks at whether the installation was done right, not at who did it.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor measures your windows, insulation, ceiling height and duct layout to figure out how much heat your house actually gains on a hot afternoon. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. Since summers here only last from June through August, getting the size right matters more for comfort than for running all year.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together, replacing just the outdoor unit usually is not a good option. The coil and the condenser are matched to work at a specific capacity, and pairing an old coil with a new condenser can mean poor cooling and a shorter life for the new equipment. A contractor can check the age and condition of the indoor coil and tell you whether it can pair with new outdoor equipment or whether both need to go at once.
- Do HVAC contractors in Martinsburg need a state license to work on my home?
- Yes. West Virginia requires HVAC contractors to hold a state license through the Commissioner of Labor, and that license covers the contractor doing the work, not 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. Ask to see the contractor's license number before the work starts.
