Overall System Maintenance Checklist
Your contractor should complete the following each spring and fall:

- Check thermostat settings to ensure the heating and cooling system turns on and off at the programmed temperatures.
- Tighten all electrical connections and measure voltage and current on motors.
Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.


- Lubricate all moving parts.
Parts that lack lubrication cause friction in motors and increase the amount of electricity you use. It can also cause equipment to wear out more quickly, requiring more frequent repairs or replacements.
- Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). If plugged, the drain can cause water damage in the house, affect indoor humidity levels, and breed bacteria and mold.
- Check system controls to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.
- Inspect, clean, or change the air filter in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this yourself. Depending on your system, your filter may be found in the duct system, versus the heating and cooling equipment itself. A dirty filter causes energy costs to be greater than they should be and can damage your equipment, leading to early failures.
