When preparing for your air duct cleaning, please make sure that we have access to all of your supply and return vents. This typically means we will need access to every room in your home. Some supply vents (the floor registers) may be covered by furniture. Please make sure you have the furniture pulled out of the way prior to your air duct cleaning. Please also remember that because we use a truck mounted power vac unit, that we will need to have a door propped open to the outside. If you have any pets that may attempt to make a run for it, please make sure you place them in a secure location before we start our process. Thank you for your help!
