A tune-up is scheduled work on a system that still runs. A diagnostic is what you call after it stops. The difference shows up in the first week of real heat, when every unit in McClain and Cleveland County that spent June coasting on a weak capacitor quits in the same three days. Oklahoma hail season opens in early March and peaks in April and May, while the condenser sits idle and unwatched. Bent fins and a nicked line set rarely stop a system outright; they bleed refrigerant slowly, and the first symptom is a July afternoon when the house will not quite cool. Red dirt loads the coil and blower wheel faster than most climates, and fire ants nest in warm contactor housings. Spring is when that work is still cheap. There is no flat tune-up fee here. Maintenance is billed as the $95 service call plus labor at $125 an hour during business hours, one hour minimum, plus parts. If the visit finds a repair you approve the same day, the $95 comes off. The $299 a year Service Agreement covers a spring and a fall visit, 10% off non-warranty parts and priority scheduling, with each additional unit $50 more per year.

March to April, before the first sustained hot stretch6 of 8 are Oklahoma-specific
Book before the first 95-degree week rather than during it. Once the heat arrives everyone calls at once, and a system that would have been a scheduled tune-up becomes an emergency call at emergency rates. Spring is also the first chance to see what winter and early hail season did to the outdoor unit.
Condenser coil cleanedOklahoma
Red-dirt dust packs into condenser fins faster here than in most climates, and a loaded coil makes the compressor work against pressure it was never sized for.
Condenser fins and line set checked for hail damageOklahoma
Oklahoma hail season starts in early March and peaks April to May. Bent fins and damaged line sets are a common cause of slow refrigerant loss that homeowners never connect to a storm months earlier — and it is often claimable on a homeowner's policy.
Refrigerant charge and airflow verified
A low charge means a leak, not consumption. Refrigerant is a sealed loop, so topping off without finding the leak means paying again next season.
Capacitor tested under loadOklahoma
Capacitors are heat-rated, and Oklahoma summers run them past their comfortable operating temperature for months. This is the single most common no-cool failure we see between June and September.
Contactor inspected for pitting and pestsOklahoma
Fire ants nest in the warm contactor housing and bridge the contacts. Along with red dust on the contact faces, it is a leading local cause of a dead outdoor unit.
Blower wheel and filter checkedOklahoma
A restricted filter is the cheapest cause of an expensive failure, and blower wheels load with fine dust faster here than the schedule on the filter box assumes.
Condensate drain clearedOklahoma
Attic and closet air handlers are the norm in Central Oklahoma rather than basements, so a blocked drain damages ceilings rather than a concrete floor.
Electrical connections tightened and thermostat verified
Loose connections cause heat, and heat causes the next failure.
A tune-up is scheduled work on a system that is still running. A diagnostic on a system that has already quit is a separate $95 service call, waived if you approve the repair that same visit. Call 405-420-4895 to book.
