Advanced Air Quality Inc

$350 + tax . I had about 13 registers including two cold air returns and an accessible crawl space. So pleased I decided to go with these guys as opposed to my original choice. Price was right on the market. Ryan arrived on time, worked efficiently and left on time- everything clean. He looked professional and acted professional. He took before and after pictures for me. Amazing work. In a house with 2 large dogs...I won't be waiting 4 years for the next cleaning and I will hire this company again. Great job. M smith, Ottawa
