We smell a foul odor whenever our propane furnace is on. The odor seems like a cross between propane and sewer gas. Our furnace is a Trane and about 15 years old. This is driving us crazy. We would appreciate any help you can provide. Thank you.

:eek: I cannot stress enough unless you are 100% positive you do not have a propane leak I would get someone over quickly with a leak detector. The furnace could be pulling the leaking gas into the supply ducts and sending it around the house.

Once you have verified this is not a propane leak repost and we can give you some ideas.
