Five months of real heat, every year
Grady County gets five months of cooling season, May through September, with summer afternoons averaging 92°F. That is a long stretch for a new system to run well and hold up.
Hail and wind come with the territory too. The last ten years brought 146 hail events and 145 damaging wind events, with hail as large as 3.75 inches. Outdoor equipment here needs to be installed and positioned with that in mind.
Any new central air conditioner has to meet the federal efficiency minimum of 14.3 SEER2. That is the baseline a licensed contractor will build your installation around.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license, and it belongs to the contractor, not the job. That means the same license covers whatever HVAC work that contractor takes on, this installation included, rather than being issued fresh for each one.
For this job, that license is what stands behind the contractor putting in your air conditioner. Most cities and counties in Oklahoma also require a permit for a new air conditioner and an inspection once it is installed, so the local building office looks at the finished work separately from anything the state license covers.

- What size air conditioner does my house need?
- There is no answer that works from square footage alone. A contractor sizes the unit with a load calculation that accounts for your insulation, your windows, your ductwork, and how much shade the house gets. Putting in a unit that is too big cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. Too small, and it runs the whole afternoon without catching up, especially with summer highs here averaging 92°F. The contractor doing the install is the one who should run this calculation, not guess from a chart.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil is old, replacing only the outdoor unit usually causes problems. The two are matched to work together, and pairing a new condenser with an old coil can mean the system never reaches its rated efficiency, sometimes voiding the warranty on the new part. If your indoor coil and ductwork are still in good shape and only a few years newer than the outdoor unit, a contractor may be able to replace just the condenser. That is a judgment call that needs someone to look at both parts in person.
- Do HVAC contractors in Chickasha 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 the person or company doing the work regardless of which house they're at. For a job like installing an air conditioner, you'll also likely need a permit from the local building office and an inspection once the work is finished.
