Ardmore summers keep a new AC working for five months straight
From May through September, your air conditioner is running most afternoons here, with highs averaging 93°F. That is five months of steady work, not just a few hot weeks, so the unit you install needs to hold up to a long season, not a short one.
Carter County has also logged 75 hail events and 40 damaging wind events over the past ten years, with hail up to 3 inches. The outdoor unit sits exposed to that, so the cabinet and coil need to take a hit and keep running. Any new central air conditioner installed today also has to meet the federal minimum of 14.3 SEER2, so it starts out more efficient than older systems it replaces.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license, and it covers the contractor, not the job itself. The same license that covers a furnace repair covers this air conditioner installation, because Oklahoma licenses the contractor rather than each separate job.
For this job, that license is what stands behind the person doing the work. Separately, an air conditioner installation in most cities and counties needs a permit from the local building office, with an inspection once the work is finished. That inspection checks the installation itself, the wiring, the refrigerant lines, the way the unit is set, not the contractor's license.

- What size air conditioner does my house need?
- There is no single number that fits every house on your street. A contractor works this out with a load calculation, which weighs your square footage against your insulation, your windows, your ceiling height, and how much shade your house gets in the afternoon. Guessing at size backfires either way. Too big and the unit cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. Too small and it runs nonstop through those 93°F afternoons and still falls behind. A contractor measuring your actual house is the only way to get this right.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are the same age, replace both together. They are matched to work as a pair, and putting a new outdoor unit against an old indoor coil often means the new unit never reaches the efficiency it was built for. Some manufacturers will not honor the warranty on a mismatched pair either. A contractor can look at the condition and age of what you have and tell you whether the indoor coil still has enough life left to make a partial swap worth it.
- Do HVAC contractors in Ardmore need a state license to work on my home?
- Yes. Oklahoma requires HVAC contractors to hold a state license, issued through the Construction Industries Board. The license belongs to the contractor, not to any single job, so it covers them for installing your air conditioner the same as any other HVAC work. Most cities and counties also require a permit for a new air conditioner installation, along with an inspection once the work is finished. Check with your local building office on the permit before the work starts.
