I bought a house and this is the 2nd winter (1st full winter) that we have been living there. The house is heated with oil/forced air and I've notice that an oil smell is present when the fan kicks on. Now, there are 3 registers on the 1st floor, 1 in the basement and 3 more upstairs and the smell seems to be present primarily only on the 1 register on the 1st floor. I have a C02 alarm and it has never gone off, but last night the smell was bad for a good 10 seconds after the fan kicked on, so much that I lit a scented candle to lessen the smell.
Could this be caused by the heat exchange, and why is the smell primarily coming out of the 1 register?
