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:
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
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
Regular preventive maintenance, performed twice a year, can help your system keep up with seasonal temperature swings. Plus, it can increase HVAC performance and help you avoid costly emergency repairs—because no one wants to be left without heat in the middle of a snowstorm. While most newer heating systems require little maintenance, a quick tune-up can greatly extend the life of your HVAC equipment, ensuring it always runs at peak efficiency.
