Here’s the latest issue I found just over a week ago.  I discovered 1 of the HVAC return air ducts was not going through the ceiling.  I took a picture of the ceiling where we found it should be coming through.  The duct was run in the Attic but they just put sheetrock over it so it was terminated to the ceiling with no air flow.

Here’s a pic of what it looks like now.

The HVAC tech was out to work on the nasty smell that comes in when it’s cold outside with high humidity and cut out the sheetrock and installed the vent.  The cause of the nasty odor hasn’t been found and now that it’s warm we will have to deal with that again next winter.  After 5 times working on it over this last winter they still haven’t figured it out.  I’m guessing we will have to go to Armstrong Air directly (just like we had to go through the manufacturer of our patio door to get it resolved after Maverick Homes tried replacing it twice without success).
