    Can also be a sign of reverse stack effect, where attic air is pushed into the house through air leaks in the ceiling.
    • Electricity makes refrigeration happen.
    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.


    A building is NOT beautiful unless it is also comfortable.

    If your return air duct is in the living room and you are closing any doors that have supply vents with no returns in the rooms it will create a negative pressure in the living room that will suck in attic air through leaks in the attic floor, like shophound stated

    Wow a lot of answers thank you everybody.
    So let me explain better i smell attic nearby the return in the living room, my duct work are located in the attic, and so the filter, i have just purchased this house and the old AC didn' t pass the inspection so i got a new one for free. I believe is a leak but i dunno where it can be. bedrooms are ok i also have a return in the master and one in the hallway by the guest bedroom.

    so..you smell it all the time or when the hvac system is running?

    do you have recessed lights?

    return in in ceiling or low on wall with return air chase?
    (where do you change filter ceiling or wall?)

    best of luck.

    Does the attic smell like the living room? Just couldn't resist.
    ..

    Seriously though, a pressurized attic or depressurized living room. Leaky ducts.

    It could be that the furnace is suching air from the plenum ?
    There are some holes like the one for the gas line, it seems to me that is sucking air also from there

    yes.

    the return ductwork and the supply (cold air vents) ductwork need to be totally sealed, if you got the system for free, it's possible the company that installed it was a low bidder and they did a SUBSTANDARD job on the install. did the system get a ductwork inspection? was there a permit pulled for the job?

    Sounds like you've got a leaking duct system. Get a good light and start looking, you'll find it. Start where the ducts connect to the return where you smell the "attic" odor.
