HVAC Services San Antonio TX | Call Locke Service Company

Yes, a refrigerant leak is a common cause of poor cooling in San Antonio homes. It reduces your system's capacity and efficiency. Our technicians use advanced electronic leak detectors to precisely locate the leak. We then repair the issue—whether in the coil, line set, or connections—and recharge the system with the exact manufacturer-specified refrigerant amount, restoring full cooling power and efficiency.

An oversized system short-cycles, turning on and off too frequently, which strains components and fails to dehumidify properly. An undersized system runs constantly, struggling to keep up and driving up energy bills. We perform a Manual J load calculation, which factors in your San Antonio home's square footage, insulation, window types, and local climate to determine the precise system capacity needed for optimal comfort, efficiency, and longevity.

Key signs include uneven temperatures between rooms, excessive humidity indoors, unusually high energy bills, and the system running non-stop on hot days or cycling on and off every few minutes. If you're experiencing these issues, it's likely a sizing problem. We recommend a professional assessment and load calculation to ensure your system is correctly matched to your home's needs for reliable performance in our Texas heat.
