I came to sears because I googled air duct cleaning and my zip code. all the reviews said how great Andy and Zach were, so I called and quickly got my service scheduled for the following day. I am so happy with the services that I received. I too got Zach and Andy as my technicians, and low and behold, they are super to work with! They guided me through the process and were in and out within an hour, and that included additional services I chose to purchase while they were here. I am so glad I added the UV light into my system. Later that afternoon, someone walked into my house and mentioned 'how good it always smells' in my home, and they were smelling the deodorizer. It smells so clean and feels more pure in my home. My cat who has been sneezing a lot lately stopped sneezing immediately after this service. The only thing that would be more helpful is a more specific window of time when they'd get here. The time window I received was 10-1 and they showed up at 12:55. All in all, a great, thorough, and pleasant service. THANK YOU!
