Maintenance Checklist

Maintain your equipment to prevent future problems and unwanted costs. Keep your cooling and heating systems at peak performance by having a contractor do annual pre-season check-ups. Contractors get busy once summer and winter come, so it's best to check the cooling system in the spring and the heating system in the fall. To remember, you might plan the check-ups around the time changes in the spring and fall.

Cooling & Heating Maintenance Checklist

Check thermostat settings

This ensures the cooling and heating system turns on and off at the right 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.

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.

Check controls of system 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 air filters once a month 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 cooling and heating equipment itself. A dirty filter cause energy costs to be greater than they should be and can damage your equipment, leading to early failures.
