Maintain your equipment to prevent future problems and unwanted costs. Keep your cooling and heating system at peak performance by having a contractor perform annual preseason check-ups. Contractors stay busy in the summer and winter, so it's best to check the cooling system in the spring and the heating system in the fall. To help you remember, plan the check-ups around the time changes in the spring and fall.
A typical maintenance check-up should include the following.
- Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
- 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 increases the amount of electricity used.
- Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump when in cooling mode. A plugged drain can cause water damage in the house and affect indoor humidity levels.
- Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.
