    A UV lamp might not even be necessary to fix this issue, but a contractor onsite should be able to determine that. Good luck.

    I have a service agreement with my HVAC co. - they last came in June (supposed to include cleaning the coils). Should be back next month.

    Still seem like dirty sock syndrome?
    It has been in the cooling mode 100% of the times I have encountered it.

    Very thoroughly cleaning the coil may get rid of it for a season, but it usually comes back. Replacing the coil with a coated coil is the only 100% positive way to do away with it permanently.
    If more government is the answer, then it's a really stupid question.

    And I should add "that I am aware of" to the end of the last line of my post.

    I only know of trane manufacturing a coated coil to permanetly solve the issue. Do other brands also make a coated coil?

    Unless things have changed in the last couple of years, Carrier, Lennox and Rheem/Ruud don't, we just order a new coil and ship it off to get the Technicoat treatment.

    Unless it is a warranty situation, we do the same with Trane coils. The Technicoat process coats everything but the drain pan. In addition to permanently solving the DSS issue, it protects the tube sheet from rusting out, and the copper tubing from formicary corrosion.

    The coated coils from Trane only have the fins coated, so while they solve the DSS issue, there is still potential for the formicary corrosion and rusted tube sheet issues.
