Summer Furnace Storage — How to Prepare Your Furnace for Idle Months

Your furnace sits unused through summer. Proper preparation prevents odours, moisture issues, and problems when you restart your furnace in the fall.

Expert Tips for Summer Furnace Storage — How to Prepare Your Furnace for Idle Months

1. Replace the air filter at the end of the heating season — a fresh filter prevents dust and allergens from circulating if you use the fan-only mode during summer. 2. Clean the blower compartment — vacuum dust and debris from around the blower motor, the blower wheel, and the control board area. 3. Check the condensate drain line — pour a cup of water with a small amount of bleach down the drain to prevent algae and mould growth during summer idle months. 4. Leave the furnace power on — do not shut off the furnace breaker. The furnace needs power for the control board and to run the fan for summer cooling. 5. Close the outdoor combustion air intake if adjustable — this prevents warm humid summer air from entering the furnace and mechanical room. 6. Check the humidifier pad if you have a furnace-mounted humidifier — clean or replace the pad for the next heating season and close the water supply valve. 7. Inspect the venting system for any damage that may have occurred during winter — check PVC pipes for cracks or separation at joints. 8. Consider scheduling annual maintenance during summer — HVAC companies have more availability and may offer off-season discounts.
