An annual inspection allows a technician to identify dirty coils and burned out contactors before they cause long term damage to your system.
Many dealers provide priority service for their customers who have an annual maintenance or service agreement. Bi-annual preventative maintenance will ensure that your system runs as efficiently as possible. Your local dealer will perform the following tasks, depending on the unit:
- Outdoor Unit: Inspect unit for proper refrigerant level and adjust if necessary. Clean dirt, leaves, and debris from inside cabinet. Inspect base pan for restricted drain openings—remove obstructions as necessary. Inspect coil and cabinet—clean as needed. Inspect fan motor and fan blades for wear and damage—on older models lubricate as needed.
- Indoor Unit: Inspect and clean blower assembly (includes blower housing, blower wheel and motor). On older models, lubricate motor and inspect and replace fan belt if needed. Check combustion blower housing for lint and debris and clean as necessary. Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed. Inspect for gas leaks in gas furnaces. Inspect burner assembly—clean and adjust as needed. Inspect control box, associated controls, wiring and connections. Clean or replace air filters. Inspect conditioned airflow system (ductwork)—check for leaks.
