HVAC Services Saint Louis MO | Call Westport Heating & Cooling

Here in St. Louis, high humidity and dirty air filters are common culprits for frozen coils. A frozen coil blocks airflow and stops cooling. We'll first safely thaw the system, then diagnose the root cause—whether it's low refrigerant, a dirty filter, or a failing blower motor. Our repair ensures the coil operates efficiently, preventing future freeze-ups and protecting your compressor.

Absolutely. AC capacitors, which help your compressor and fan motors start, are prone to failure during our St. Louis summer heatwaves. A failed capacitor is a very common emergency call we handle. Our technicians carry a wide range of capacitors on our trucks and can typically diagnose and replace a faulty one on the same visit, getting your cool air back quickly.

Our local-focused maintenance tune-up is your best defense. We specifically check refrigerant levels to prevent coil freeze-ups, test capacitors for early signs of weakness, clean coils, and ensure proper airflow. This proactive service, ideally performed each spring, catches small issues before they lead to a breakdown on the hottest day of the year, saving you money and stress.
