HVAC Repair in Porum, OK | Refrigerant & Duct Leak Specialists | Cotner Refrigeration & Air

Yes, that's a common sign of a refrigerant leak, especially in our hot Oklahoma climate. Low refrigerant makes your system work much harder, increasing energy bills and risking compressor failure. We perform a thorough leak detection test to locate the source—often at a coil connection or in the line set—and repair it before recharging the system to its factory specification, restoring efficiency and cooling power.

This often points to leaks or disconnections in your ductwork, a frequent issue in local homes. Leaky ducts force conditioned air into your attic or crawlspace instead of your rooms. Our technicians inspect your entire duct system, sealing any gaps or reconnecting separated sections. Properly sealed ducts improve airflow, balance temperatures room-to-room, and can significantly lower your monthly energy costs.

Regular maintenance is key. Our seasonal tune-ups include checking refrigerant pressure for early signs of loss and inspecting accessible ductwork for gaps or damage. Catching a small leak early prevents major repairs and keeps your system running efficiently. We also advise homeowners to be mindful of any unusual hissing sounds near the indoor unit or visible damage to exposed ducts, as these are early warnings.
