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.
