At Comfort by Design your air duct cleaning starts with an inspection of the ducts that lead to the return and supply registers. This allows the technicians to inspect the ductworks for leaks or possible kinks. The next step is to create a negative pressure using a large vacuum that will pull the dust and debris captured inside your home duct system. After the duct system has been cleaned your Comfort by Design technician will then clean the rest of the components as well as changing the filters to make sure your system is operating at its highest efficiency.
