At Marks Duct Cleaning, our certified and qualified cleaners follow an exclusive central duct cleaning process to ensure that you get a flawless service. We arrange of a visit by our cleaners as per your availability once you give us a call. Then our cleaners visit your place for a pre-inspection of your central duct system to notice what kind of work is required. We do pre-vacuuming in some cases and then we check the heater to see it is functioning properly. Then using air guns, we clean the filters and other parts of the duct system including return air vent. The last step is to clean the heating unit comprising motor and fan and then we deodorize and sanitize your ducts. We make your ducts healthier, fresher, and more hygienic.
