Dirty Sock Syndrome?

[George Hallaron]

Has anyone had any experience dealing with this issue of the heat pump blowing a sour smell when you first reverse the cycle or it drops below 40 degrees? I have a client that is at their wits end. The hvac contractor is blowing them off, and the Trane unit is still under it's one year service warranty. As I know only what I have read about the condition, any insight would be appreciated.

Thanks,

I don't have any experience with it - Dirty Sock Syndrome doesn't seem to be a problem in the northern states. But I've read about it and it seems like antibacterial coatings are the answer. Check out this article:

Thanks Jim,

Thats the ammunition I need to present to my clients. It does seem however, that it's an inherent manufacturing processing defect for cost cutting purposes.

Thanks for the response plummen,

Yes, they have been keeping the filter changed regularly and the coils appeared clean and free of any debris.
