Sanitizing duct work

Hi All, just got 2 quotes for central AC replacement both included sanitizing the duct work which is primarily flex duct,I have never heard of this before,is this some kind of a gimmick?

Since nobody in my area does it. I'll say yes, it is another method to get more of your money. There may be some merit to it but I assume it's like an auto dealer putting on their "special" paint protection package (wax) and charging you $750.

It's a service that is out there but I question it's overall benefit.

Over the course of 6 new homes I've had the opportunity to get into my ducts and other than some minor construction debris all I have ever found is a light coating of dust.

Now I understand that my ducts are only 6-8 years old but when you see their advertising and the ducts are coated with 3" of crud I suspect that is a very rare condition.

As far as "sanitizing", well I think Id consider sending the family out, turning on the blower, and using up a couple cans of Lysol!

If the duct is not clean first then you would only be hitting the top of the dirt. I wish someone would take these guys to court for false clams. No way to sanitize the inside of duct. You can treat it and that is about it.
