This is a common sign of an evaporator coil freeze-up, often caused by restricted airflow from a dirty filter, low refrigerant, or a failing blower motor. For your safety and to prevent further damage, turn the system off and call us. Our technicians will diagnose the root cause, whether it's in Stockton's humid air straining your system or a specific component failure, and provide a lasting repair.

While we can maintain older systems, waiting for a failure in the middle of a Missouri winter is risky. Modern HVAC systems are significantly more energy-efficient, which can lead to noticeable savings on your utility bills. We offer a free, no-pressure evaluation to compare the repair costs of your aging equipment with the long-term benefits and comfort of a new, reliable system tailored for our climate.

Proactive maintenance is key. Our local service includes cleaning coils and checking refrigerant levels to prevent freeze-ups, inspecting electrical components, and ensuring proper airflow—all common issues for Stockton homes. A regular tune-up helps your system run efficiently, extends its lifespan, and catches small problems before they lead to a costly emergency repair or a complete breakdown.
