Qualified HVAC Repair in San Antonio, TX 78260 - 24 7 Air Conditioning & Heating

This is a common issue in our area and often points to two main problems. First, the system may be improperly sized for your home, a frequent installation error. An oversized unit short-cycles, while an undersized one runs non-stop. Second, it could be a refrigerant leak, which reduces cooling capacity and forces the system to work harder. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a sizing issue or a leak—and provide a lasting solution to restore efficient cooling.

Key signs include reduced cooling power despite the system running, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills. Refrigerant doesn't get 'used up'; if it's low, there's a leak. It's crucial to address this quickly, as low refrigerant makes your compressor work excessively hard, leading to premature failure. We use specialized electronic leak detectors to find even the smallest leaks and perform EPA-compliant repairs to protect your system and your investment.

Proactive maintenance is your best defense. Before peak summer, schedule a professional tune-up. We'll clean coils, check refrigerant levels, inspect electrical components, and ensure everything is operating at peak efficiency. This can prevent breakdowns when you need your system most. Also, ensure your air filters are changed monthly during heavy use to maintain proper airflow. If your system is over 10 years old or has a history of repairs, consider a pre-season evaluation. We can assess if it's properly sized for your home and discuss energy-efficient replacement options to avoid emergency failures.
