how often do you need to have your ducts cleaned?

modelageDecember 10, 2011

We moved into a 4 br. 3000 sq. ft single family home in the burbs a year ago and put in a new kitchen last month. We had the ducts cleaned last week because we didn't know how much dust might have gotten in from the construction. It seems no duct cleaning had ever been done in the 30 years since the house was built (no opening on any of the ducts).

The house didn't seem particularly dusty before our construction but it was afterwards and the duct cleaning took care of that.

The team that did it said you need to do this every two years, but given that the house was fine before construction, I wonder if it's overkill?

Unless you ACTUALLY have mold or ACTUALLY have vermin living in the ducts or ACTUALLY have duct blockage, a case can be made to not spend your money on duct cleaning per the EPA.

true.
if the system is well sealed there is no need
for duct cleaning.

when they cut the holes in the ducts..did they
screw them shut and mastic seal them?
I've seen systems where duct cleaning holes
were improperly sealed.

keep in mind that they are selling you a service.

best of luck.

Anyone that cuts holes should close them up adequately and correctly.

Why do you think there is material in the ducts that needs to be removed?
