HVAC Services San Antonio TX | Call San Antonio Air Conditioning and Repair

Common signs of a refrigerant leak in our climate include your AC blowing warm air, ice forming on the refrigerant lines or outdoor unit, and a noticeable drop in cooling capacity despite the system running constantly. If you suspect a leak, it's important to call a professional like us right away. Running a system low on refrigerant can damage the expensive compressor. We'll locate the leak, repair it, and recharge the system to the manufacturer's exact specifications, restoring your cooling power and efficiency.
