I am in Western Washington & I have a forced air furnace (ancient) that has a coil coming from the fireplace (because the fireplace is tied into the furnace ducts) and it is sending soot through the house when I use either. I had a chimney company come look at it & they won't service it or even touch it. They want to rip out the wall & start from scratch. Just so you get a visual here, my kitchen & living room are separated by (in order) furnace, fireplace, water heater, all walled in with doors at either end for furnace or water tank. The chimney guy just gave me a brochure for a free standing gas stove! Who wants a gas stove in the same room as a non functioning fireplace?!?! Who even begins to fix stuff like this? No one I have called will even look at it! I have 1 quote for $6,000! - would love to maybe have a pellet stove in there, but was told the opening was not big enough. I am beginning to think a Rocket Mass stove is looking really good right now. Has anyone heard of a fireplace tied into the ductwork of a furnace & if so can troubleshoot with me on why its puking soot out the vents in the upstairs rooms? Thanks for reading my rant/plea for help. I know people at this site are very intelligent & full of great advice!
