Five months of hard running, plus what the storms leave behind
Your air conditioner works from May through September here, and on a 92°F afternoon it runs long stretches just to hold the house steady. That kind of load wears on the parts that keep the system cooling, the compressor and the refrigerant lines, and a system that starts the season low on refrigerant only gets worse from there.
Pottawatomie County has also seen 59 hail events and 57 damaging wind events over the past ten years, with hail up to 2.75 inches. Hail bends the thin fins on the outdoor unit's coil, and wind can knock the unit out of level or throw debris into it. A tune-up checks the coil and the refrigerant charge before either one leaves you with a summer of poor cooling.

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 contractors before they get that license and keeps a record of who holds one. It covers the contractor as a whole, not the specific visit to your house, so the same license applies whether the job is a repair, a new install, or a maintenance check like this one.
For AC maintenance, that license is what stands behind the person working on your system. If the technician opens the refrigerant side of the unit, checking the charge, for instance, federal law also requires them to hold EPA Section 608 certification. That certification is separate from the state license and applies to that kind of work in every state.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor. They also check the blower motor, clear the condensate drain, and look over the electrical connections for wear. Only a technician with EPA Section 608 certification can open the refrigerant side, so if that part of the job comes up, that credential should be in place.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the cooling season starts. Homes here run the AC from May through September, so getting it checked in spring gives a technician time to catch a weak capacitor or a low charge before the 92°F afternoons arrive. Skipping a year does not break the unit, but it means small problems get found later, usually on the first hot day when the system is working hardest.
- Is AC maintenance worth it?
- Yes, because most of what fails in an air conditioner shows warning signs first, and a yearly check is when those signs get caught. A weak capacitor, a dirty coil, or a low refrigerant charge all cost the system efficiency before they cause a breakdown. With five months of cooling season and summer highs averaging 92°F here, an AC that is not running right gets tested hard for a long stretch. A contractor can price the job for the specific house and system.
