It’s a good idea to hire a qualified contractor to perform an annual pre-season check-up and make sure everything is running smoothly. Heating and cooling companies are extra busy during the summer and winter months, so schedule check-ups accordingly—the cooling system in the spring and the heating system in the fall. Plan these service calls to correspond with the seasonal time changes, when home smoke alarm batteries are also tested.
To perform a typical maintenance check-up on your heating or cooling system, take the following steps:
• Check thermostat settings to ensure the system keeps you comfortable when you’re home and saves energy while you’re away.
• Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe system operation and reduce the life of major components.
• Lubricate all moving parts to reduce motor friction and decrease the amount of electricity you use.
• Check and inspect the condensate drain in your central air conditioner, furnace or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
• 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 filters in your central air conditioner, furnace or heat pump once a month. Your contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.
