heat pump smell
We live in a 17 year old house. We replaced the original heat pump with a Trane this past summer. We live near the Georgia Florida border.
The air conditioning worked great. The heat works fine too but during this last bit of cold weather there has been an intermittent odd odor coming out of the vents. I believe it happens when the heat strip is on but it doesn't happen every time.
It's a stale and musty odor. It doesn't smell moldy or wet. The ducts were cleaned about a year before we installed the new unit and we didn't have the smell with the old unit. I've read about "dirty sock" but I don't think that's the issue.
I have a call in to the installers but I thought would post here and get some opinions and advice. Thanks.
