Five months of heat, plus the storms that come with it
Summer afternoons in Shawnee average 92°F, and that runs from May through September, five months a year. Whatever you install has to hold that line every one of those afternoons, not just on the hottest days.
Pottawatomie County has also seen 59 hail events and 57 damaging wind events over the past ten years, with hail as large as 2.75 inches. The condenser sits outside through all of that. If you're installing new, federal rules since 2023 set a floor of 14.3 SEER2.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests and licenses HVAC contractors before they can do this work in Oklahoma. That license belongs to the contractor, not to any single job, so the license that qualifies someone to install an air conditioner in Shawnee is the same one that qualifies them for the next job down the road.
In Pottawatomie County, that license is what stands behind the person doing the installation. In most cities and counties, the job also needs a permit from the local building office and an inspection once the work is done, to check that the unit was put in and connected correctly.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have, and which way your house faces, not just a rule of thumb. A unit that's too big cools the air fast but shuts off before it pulls the moisture out, so rooms feel clammy. A unit that's too small runs constantly and still can't keep up on a 92 degree afternoon, which is about what summer brings here from May through September. A contractor will do a load calculation on your actual house before recommending a size.
- Should I replace the whole system or just the outdoor unit?
- If your outdoor unit and indoor coil are more than a few years apart in age, replacing just the outdoor unit usually isn't worth doing. The two are matched to work together, and pairing a new condenser with an old coil can mean the system never reaches the efficiency either part was built for. It can also void the warranty on the new equipment. A contractor can check the age and condition of both and tell you whether a full system swap makes more sense than a partial one.
- Do HVAC contractors in Shawnee 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. That license belongs to the contractor, not to each individual job, so it covers the person or company doing the work rather than being reissued for every install. Installing an air conditioner also typically needs a permit from the local building office along with an inspection once the work is finished.
