    Furnace exhaust color
    Hello - I have gas furnace in my home - a Lennox 75,000 80% furnace G23 q2/3-75 - with a 5"x 25' chimney liner that was installed in 2000.

    I keep the area around my funace very clean and I open up and clean it out regularly.

    Yesterday, my neighbor stopped by to tell me that they noticed black and brown colored exhaust coming from my chimney a few times that day. Can anyone tell me what this might mean? Any help would be greatly appreciated - thanks.
