DIY HVAC Maintenance Tips
These popular internet tips suggest ways to gauge the status of your system and to prepare for a maintenance technician to service your unit. Be sure not to excessively tamper with your unit and run the risk of voiding any warranties you may have. When in doubt, err on the side of caution and contact your dealer or a technician with questions.
- Keep the area around the main cabinet and control box clear and easy to access. Cut any high grass and clean away any dirt, leaves, and debris.
- Inspect the base pan for anything that could block the drain openings. A plugged drain can cause water damage and affect humidity levels in your building.
- Inspect the cabinet and coil for any leaks or holes. You may opt to clean the evaporator or condenser coils in your cooling system to help the system run more efficiently. Dirty coils cause the system to run longer just to complete the same tasks.
- Inspect the fan blades for any wear or damage. Be sure to check them both while they’re in motion and stationary.
- Check to make sure the moving parts within your system are properly lubricated. Parts that lack lubrication may cause friction in your motor and reduce your system’s efficiency.
- Clean and/or replace filters. This is recommended on a monthly basis.
- Check for the ductwork for any leaks.
- Be conscious of any unusual odors or noises when the system is started.
- Inspect your control box for any wiring and/or connections issues. Some connections may need to be tightened.
Test the emergency controls of the system to ensure that it operates effectively whether you need it to start, run or shut off in the event of an emergency.
- Inspect and clean blower components. These may need to be adjusted to provide proper system airflow and allow your system to operate at maximum efficiency.
