how often do you need to have your ducts cleaned?
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?
