    Question

    Hi Guys,

    Last week I had a contractor install a Goodman 3.5ton 10 seer outside unit with CAUF042B2A coil. We tested the airconditioning and it worked fine. Buth whenever we switch on the (2 years old gas furnace) heating (after air conditioner install), there is an odor from all vents. The odor is like a uncleaned fish tank (fishy). When I just run the fan (without heat), I don't get any odor. But when I turn on the (gas furnace)heater, the odor comes. Before the air conditioner install, we never got any odor when running the (gas furnace)heater. So we believe that the coil is causing the odor when hot air touches the surface of it. Please help!

    The contractor is puzzled and trying to get an answer from Goodman.

    Sounds like you may have something on your heat strips. When they energize they get very hot and what ever is on them will burn. Dusty heat strips do that too but the smell goes away after a while. See if you can make an opening in the plenum to inspect the heat strips. You may also have something in the duct system itself. Warm air usually makes odors more noticible.

    On new installed furnace it is normal to get a smell of oil being burned which goes away after a couple days of being ran. Usually i tell the HO to have doors open while this odor goes away.

    Didn't he post its a 2 year old GAS furnace.

    Does it smell fishy, or some what like a dirty sock?

    Sounds like the contractor may have dropped something in the furnace.Have they taken the coil off and looked?

    Have him do a chemical cleaning to it, and make sure the coil isn't slanted away from the drain.

    If it comes back, you'll either need to add a UV light, or get a coated coil.

    What's odd is that this is the second thread about a smelly coil. I wonder if there isn't something going on in the processing of these coils.

    How close is the drain pan to the furnace heat exchanger? Is the coil smaller then the furnac opening? Is the heat rise from the furnace excessive?

    Hi RoBoTeq,

    The coil is mounted right below the furnace (Trane XB80). The coil height is 20" and the width is 16 1/2". The duct is 17 1/2" wide. The drain pan is on the base of the coil. So it should beapproximately 20+ inches from furnace heat exchanger.

    Thanks.
