Replace the air filter when the furnace is no longer in use. Vacuum any dust from the compartment that holds the filter before inserting a new one.
Turn off the pilot light on a gas or propane furnace. This allows the air conditioner to run more efficiently during the summer. This also prevents gas leaks if your pilot light should go out on a furnace that's older and lacks an automatic shutoff function.
Use a vacuum with a long hose attachment to clean dust from around the blower fan and around the bottom of the furnace closet. Notice that the fan collects dust over the winter months. Cleaning it prevents mold spores and dust mites from spreading throughout your home via the duct system while the air conditioner is being used.
Inspect your furnace for loose connections. During the winter, the ducts may contract and expand from the constant variations in temperatures, causing gaps in the connections.
Check for a smooth motion in the fan blades. Come summer, the motor may stick. Use spray lubricant to allow the blades to move with ease.
Clean the air registers. Over the winter, dust particles collect and can be circulated inside your home in the summer if not removed.
Call a furnace professional to service your unit, if needed. Heating companies are less busy during the summer months; if you wait until winter arrives, you may be put on a long waiting list to receive service.
