* A dirty oil filter: When your oil filter is dirty, it can restrict the flow of oil to your furnace, causing it to overheat. This can produce a burning smell.
* A faulty oil burner: If your oil burner is not working properly, it can also produce a burning smell. This is because the oil is not being burned completely, and the partially burned oil is what you are smelling.
* A cracked or damaged oil line: If there is a crack or damage in your oil line, it can leak oil, which will produce a strong odor.
* A problem with your chimney or flue: If your chimney or flue is blocked or damaged, it can prevent the exhaust fumes from your furnace from escaping properly. This can also cause a burning smell in your house.
To eliminate the smell of fuel oil in your house, you should:
* Replace your oil filter regularly.
* Have your oil burner serviced annually.
* Inspect your oil lines for cracks or damage.
* Make sure your chimney or flue is clear and in good condition.
If you have tried all of these things and you are still smelling fuel oil in your house, you should contact a qualified HVAC technician for help.
