How Oil Furnaces Work

Homeowner DIY maintenance

Here are 3 things you can do between professional inspection to make sure your unit is running smoothly:

1. Visual and aural inspection

Look for signs of black soot around your furnace. Soot outside the furnace itself could mean that the unit is burning more than oil. You should also look at smoke coming from your chimney while the furnace is burning; black smoke could indicate that the oil is not being burned completely. Next, listen for any unusual vibrating or rattling sounds coming from the furnace blower. If you notice any of these signs, contact your local Trane Comfort Specialist.

2. Clean and dust

Turn off your furnace, including the gas line, and wait for it to cool. Then, using a vacuum with a long hose attachment, clean dust from around the furnace. Removing this dust can help reduce allergens in the air and prevent burned dust particles from circulating through the house.

3. Change the air filter

Remember to change the air filter in your furnace as often as recommended by your operator's manual, or more frequently if you own pets.

For all maintenance efforts, consult your user’s manual prior to performing these actions.

Dealer Maintenance

Here is what you can expect a dealer to do during an inspection.

Check the fan belt

As part of the regular inspection, a Trane Comfort Specialist will check the fan belt for cracks or fraying. He or she will also check to make sure the belt is tight and secure.

Lubricate the blower motor fittings

To reduce friction and extend the life of your furnace, a Trane Comfort Specialist will lubricate the fittings of the furnace's blower motors.

Clean the burner nozzle

Having a professional periodically clean the burner nozzle prevents clogs and ensures that oil can easy move into the furnace burner.
