Hello. I purchased a condo-townhouse in Fall 2001. Shortly after I moved in, I noticed a certain smell coming from the air vents (some chemical odor). I didn't think much of it at the time, and thought it would go away. Well, sometimes it goes but sometimes it comes back again. It wasn't until fall/winter of 2002 that I became concerned that it may affect my health (I don't sneeze or cough, but you never know). I hired a duct-cleaning pro to sweep out the ducts, but the smell is still there. The duct cleaner then gave me some scented odor-killer, but I'm concerned that only masks the problem. I've talked to various contractors, but still I have no idea where the smell is coming from. What are my options? Should I replace the whole duct system?

They may have had the evaporator coil chemcially cleaned before you moved in. If it were a refridgerant leak, it wouldn't last that long and you would notice it. Do you notice it more when you run your a/c?

I turned on my a/c but did not notice any increase in smell. The cold air seems to push out the odor residing in the ducts and then the cold air coming out smells ok. But when I turn the a/c off for a while the smell comes back.

The odor seems strongest from the vent furthest away from the a/c and heating units, i.e., the master bedroom vent, which seems strange.

I checked with the builder who said the drain line is not attached to the sewer line. I took a sniff from the drain line and did not smell anything.
