|In response to Re: Oil furnace smells|
Look at the furnace above the floor and at the top surface of the furnace, and also at the fill tube piping where the fuel oil delivery person delivers your fuel oil. Fuel oil has a heavy vapor that can build up and be carried into the home when the furnace fan begins circulating air. The furnace mixes fuel oil and air to make a combustible fuel that the burners burn to send heat into the living spaces. The combustion chamber is supposed to be separated from the actual heated air circulating into the house, by what is called a heat exchanger. In the event you have just received a delivery of fuel oil and some has spilled, then you'll experience a fuel oil odor for a week or so. If there is a leak of about a gallon or so a day, you'll smell the odor constantly. and even more so when the circulation fan changes the air in the house. If you are sure there are no obvious fuel oil liquid leaks, then suspect the filter that is between the combustion make up air, and the outside air. There is a slide out panel that usually requires no tools at all to slide out the old air filter, and remove it, and replace with a new filter (less than five dollars cost). If the air filter isn't the source of the odor, look at the heat register in the rooms. Thats the grill that is probably on the floor or wall where the warm air comes into the room from the furnace. That register usually has four screws that allow you th remove the register for cleaning, but you may be able to just vacuum the registers and remove oily smelling dust and dirt that had built up over the warm climate unuse period. If those self cleaning methods don't work, then you can suspect that the area where the fuel oil is entering the combustion area is leaking. PLEASE BE CAREFUL! if you see an oily deposit in the combustion area (where the pilot light is located) turn off the thermostat, and soak up the oily deposits, then look with a flashlight for a small drip along the line that supplys fuel to the burner. If you detect a small leak (less than an ounce a day) you might try tightening the fittings on the supply line till the leak stops. Before you try tightening, though, look for the fuel shutoff valve along that same line. In case you tighten too much, and break a fitting, you can shut off the supply and call for help.
: This year when our oil furnace turns on it emits an oil smell. What could be causing this and what can we do about it?
