Just like the previous posts...Advanced Air DOES NOT do what they say! 2 weeks ago we too had a mitigation system installed. They said they would leave the mitigation tester at my home for 48 hours. Well they didn't leave it. I called right away with no answer. They never answer the phone or return any of my calls. I have called at least a dozen times to no avail. It now has been 2 weeks with no response from them at all. Don't know how these guys can stay in business. Terrible experience! HIGHLY NOT RECOMMENDED! TERRIBLE !
