Do I need to have the duct cleaned even I move to a new house?

Yes, it seems a bit surprising, but we advise you to go for a duct cleaned in case of a new house as well. Because the construction debris get contaminated in the air and the polluted air can make the duct blocked. Those are the fine substances like drywall dust, sawdust and other particulates of construction materials which obstruct the free working of the unit. A professional duct cleaning service can remove those things from your machine.
