Castillo Air Conditioning: Experienced HVAC Repair Serving San Antonio 78247

Our preventive maintenance service includes inspecting and cleaning the condensate drain line, which is prone to algae and mold buildup in our humid climate. This prevents water backups, potential water damage, and system shutdowns, keeping your AC running efficiently all summer.

Signs include reduced cooling, ice on the evaporator coil, and higher energy bills. Our expert repair service involves using specialized tools to locate the leak, repairing it, and then recharging the system with the precise amount of refrigerant to restore full cooling capacity and efficiency.

If your system is over 10-15 years old, requires frequent repairs for issues like refrigerant leaks, or struggles to cool effectively despite maintenance, a replacement is often more cost-effective. Our installation service provides a modern, energy-efficient system better suited to handle our intense Texas heat, improving comfort and lowering bills.
