HVAC Repair Metropolis IL | Call Comfort Zone Heating & Air

This common issue, known as radiator heating imbalance, often occurs due to trapped air in the system or a buildup of sediment. For homes in our area, it can also be influenced by how the system was originally balanced for your specific layout. Our technicians perform a thorough system evaluation, bleed radiators to release air, flush lines if needed, and precisely adjust the valves to restore even heat distribution throughout your home.

Prevention starts with proper maintenance. Ensure your air filter is clean, as a dirty filter restricts airflow and can cause the evaporator coil to freeze. Also, keep exterior units clear of snow, ice, and debris. The most effective step is to schedule a pre-winter tune-up with us. We'll check refrigerant levels, inspect electrical components, test the defrost cycle, and ensure your entire system is prepared for Metropolis's freezing temperatures.

It's possible. Heat pumps have a defrost cycle to melt ice on the outdoor coil. If this cycle fails due to a faulty sensor, relay, or valve, ice can build up and block heat transfer, causing cold airflow. Don't try to chip the ice off, as this can damage delicate fins. Turn the system to 'emergency heat' mode on your thermostat and call us. We'll safely thaw the unit, diagnose the root cause of the defrost failure, and make the necessary repair to restore your warmth.
