Flex Duct Is Ok, But Not To Much!

Just noticed that a customer’s house has much flex duct, it’s old flex duct also. Recommend upgrading the flex duct maybe adding some more hard pipe and shorter lengths of flex. Not that this won’t work like this, but I don’t like to overdo flex duct.

Spaghetti mess. How many years does flex duct last?

That’s a good question. I guess it depends on the environment that it is in. A great environment like dry. no mice and no sun. I’d say should last 20 years but like this place the basement is very damp and moist and the old gray flex does not hold up as long. Sometimes the insulation in between breaks down or the liner breaks down sometimes you can’t tell that is 24 years old, roughly.
