That's a classic sign of an overheated compressor, a common issue in our Schertz heat. It's often caused by refrigerant issues, dirty coils, or poor airflow. We'll diagnose the root cause—checking refrigerant levels, cleaning the condenser coils, and ensuring proper airflow—to repair it and prevent future shutdowns, protecting your system from long-term damage.

High bills with constant runtime frequently point to duct leakage, which forces your system to work harder to reach the set temperature. Our technicians perform thorough inspections of your ductwork, using specialized tools to locate and seal leaks. This improves system efficiency, balances airflow, and can lead to significant savings on your monthly bills.

We recommend bi-annual tune-ups—once before summer and once before winter. Our preventative maintenance includes cleaning coils to prevent overheating, checking refrigerant levels, inspecting and tightening electrical connections, and examining ductwork for early signs of leaks. This proactive care is the best way to enhance efficiency, extend your system's life, and avoid costly emergency repairs.
