Lee's Summit HVAC Repair | Fix Coil Freeze-Ups & Heat Pump Issues | Alliance Heating & Cooling

This is a common sign of an evaporator coil freeze-up, a frequent issue in our Lee's Summit climate. It's often caused by restricted airflow from a dirty air filter, low refrigerant levels, or a failing blower motor. Turn the system off to let it thaw completely, and call us. Our technicians will diagnose the root cause—like checking for leaks or cleaning the coil—to fix the problem and prevent it from recurring.

This typically points to a problem with the heat pump's reversing valve, a component that switches the system between heating and cooling. When this valve gets stuck or fails—a common issue we see locally—it can't direct refrigerant properly. Don't keep running it, as this can cause further damage. Our expert team can test the valve's operation, electrical controls, and refrigerant charge to perform the precise repair needed to restore your warm air.

Preventive maintenance is key to avoiding local issues like coil freeze-ups and reversing valve stress. Our comprehensive service includes cleaning coils, checking refrigerant levels, ensuring proper airflow, and testing all electrical components and valves. This proactive approach catches small problems early, keeps your system running efficiently, and extends its lifespan, saving you from unexpected breakdowns and costly repairs during our peak heating and cooling seasons.
