Ductless systems get maintained less often than anything else in a house, mostly because there is no filter in a hallway to remind anyone. Each indoor head carries its own blower wheel and its own filters, and red-dirt dust in central Oklahoma loads all of it faster than most climates. A head that has quietly lost airflow still blows cold. It simply runs far longer to do the same work. This is scheduled work, not troubleshooting. A mini-split that has stopped cooling is a diagnostic call, and a different visit. Trinity maintains ductless systems in rental blocks and new builds near the OU campus in Norman, as well as in homes around Washington and Goldsby. Worth knowing on newer equipment: many ductless systems use R-32 refrigerant, an A2L that is mildly flammable and handled differently from the R-410A in older units, which is fine to keep running and to service. There is no flat mini-split tune-up price. A visit is the $95 service call plus $125 an hour during business hours, one hour minimum, plus parts, and the service call is waived if a repair is approved the same day. Multi-head systems take longer, which is worth weighing against the $299 a year Service Agreement and its $50 per additional unit.

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.
