HVAC Repair Charleston IL | Call Atteberry & Marshall Heating & Air Conditioning

Frozen components are often caused by restricted airflow, low refrigerant, or a malfunctioning blower. Our technicians diagnose the root cause—checking filters, ductwork, and refrigerant levels—then perform the necessary repairs to restore proper operation and prevent future freeze-ups.

Uneven heating is typically due to trapped air in the system or a faulty circulator pump. We expertly bleed your radiators to remove air pockets and inspect the pump and valves to ensure even heat distribution throughout your Charleston home.

We recommend seasonal tune-ups, including system inspections, cleaning, and testing. For radiator systems, this includes checking pressure and bleeding valves; for forced-air systems, it involves filter changes and coil cleaning. This proactive care improves efficiency and helps avoid emergencies.
