Five months of heat, every year
Your air conditioner in Norman runs from May through September, with summer afternoons averaging 92°F. That is five straight months of long hours on the compressor to keep the house cool.
Cleveland County has also logged 267 hail events and 163 damaging wind events over the past ten years, with hailstones as large as 3.41 inches. Hail can dent or crack the thin aluminum fins on your outdoor unit, and wind can drive debris into the coil or knock the unit out of level. A tune-up checks the coil and cabinet for damage like this before the next 92 degree afternoon puts the system to the test.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests and licenses the contractor, not the visit. That means the business doing the work has passed the state's exam and is on record with the board, and that record stays with the contractor across every job they take on, not just this one.
For a maintenance visit on your air conditioner, the license tells you the contractor is who the state says they are. If the technician opens the refrigerant side of the system to check the charge, they also need EPA Section 608 certification, which is a federal requirement in every state and separate from the Oklahoma license.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil, the blower, and the condensate drain to make sure it's draining and not backing up. They also check airflow and confirm the thermostat is calling for cooling correctly. Any of these can cause a breakdown on its own, so a real visit covers all of them, not just a filter swap.
- How often does an air conditioner need maintenance?
- Once a year, before the weather turns hot. Homes in Norman run the air conditioner from May through September, so scheduling it in spring means it's checked before that stretch starts rather than partway through it.
- Is AC maintenance worth it?
- Yes, because most of what causes a system to fail in the middle of summer shows up earlier as a small problem, a weak capacitor, a dirty coil, a clogged drain. Catching it in spring means the unit has already been checked before Norman's summer afternoons hit 92°F. It also matters here because of the storms. With 267 hail events and 163 damaging wind events recorded over the last ten years, an outdoor unit takes a beating, and a yearly check is a chance to catch bent fins or storm damage before the unit has to work through the next stretch of hot weather.
