I called Preventilation to clean the air ducts at my moms house because they were in need of a serious cleaning. It had to have been over 5 years since she last got it serviced, and it was gross. Marc was professional, answered all of my mom’s «silly» questions, and charged what I felt was a reasonable fee for such a mess. He also left the area clean, which is one of my pet peeves. And it only took 3 days to get an appointment! Would highly recommend.
