Shortly after buying a 2 year old home I discovered two problems I needed a solution to. The first was smoker's odor caused by the previous owner's in-house smoking habit. The other was a need to replace a broken down air exchanger system that was only one month beyond warrantee service. I called a number of service providers and found that Advanced Air had answers to all of the questions I could think of and a few I had not known to ask. The rep I spoke with took the time to explain, in simple terms, all the specifications and the jargon which made me feel quite confident in my choice of their duct cleaning service as well as their Life Breath air exchanger system. I found their prices VERY competitive especially when considering the quality of service AND the superiority of their exchanger product and warrantee. When Mike, the duct cleaning technician came, he was friendly, courteous and respectful. He explained what he was doing and what I could expect at every stage of the process. He even went so far as to give me a before look at the ducts (yuk!) Given the youth of the house, their condition surprised me. Then he gave me an after look. What a difference!! As part of the service, I chose to have a deodorizer sprayed into the duct system in the hopes of eliminating the nicotine odor. Mike was kind enough to do a double application of the deodorizer as he judged the need for it. He assured me that if at some point I was not completely satisfied that he was willing to come back and give the system another shot. Mike left the work site spotless. Some weeks later I called and Mike came back for one last shot which did the job. Then came the replacement of my broken down air exchange system. The installation technician Ryan came and provided the same kind and level of awesome service. The whole experience left me feeling good about placing my trust in Advanced Air, their products and especially their service personnel Mike and Ryan. I have taken every opportunity to recommend Advanced Air to anyone looking for duct cleaning service or air exchanger equipment. Many thanks guys!
