Air Ducks cleaned my air ducts and dryer vent this week and did an absolutely great job. The Air…read moreDucks technician Chris did a thorough, detailed job and really went above and beyond. Chris also found an issue with the roof cover of our dryer vent and took the initiative to fix that. I've had a lot of workers in my home and by far, this is the best experience I've had. Also, we were able to schedule the visit within a couple days of reaching out to Air Ducks, pricing was competitive and we were not up-charged (I had 3 other Air Duct cleaning companies that either quoted me outrageous prices or kept pushing add-ons. Air Ducks gave me a price over the phone and that was the price I paid. I'm so pleased with this company that I've already given their name to several friends and my next door neighbor has already booked a cleaning with Air Ducks. This is a great company, Chris is an outstanding tech, and I will use this company whenever I need duct cleaning for many years to come.
