Warm Air System: Open the blower compartment to clean, check and lubricate the blower if applicable. Check the air filters and clean or replace them. Note the filter size on your service ticket and remind the customer to check and clean/replace the filter regularly. Check the condition and tension of the fan belt, replace and adjust as required. Check the blower mountings and bearings for excessive wear. Then properly reinstall the blower compartment door. Check the blower limit settings. If there is a humidifier, check it for proper operation, water leaks and mineral build up. Steam Boiler: Check the low water cutoff by draining water from the system until the burner shuts off. Check the automatic water feeder. Clean the sight glass and replace it and the washers if necessary. If the glass fills with dirty, oily water, skim the boiler until it clears up. Check the main vents and look for evidence of leaks. Be sure to return all controls to their proper settings and double check to be sure that you removed any jumpers. Ask the customer to reset all thermostats to their normal settings. 15 Cleanup the work area Once you’re satisfied that everything is working properly, remove old parts, oil absorbent and newspaper or drop cloths. Use your vacuum cleaner to clean the area around the system. Return your tools to their proper places in your truck and clean your hands. 16 Double-check your work Pay particular attention to potential sources of oil leaks such as the filter canister, pump, burner housing and oil valve. 17 Make it shine Wipe and clean all of the external surfaces of the boiler or furnace and work area.
