Air Treatment System's owner and operator Andrew Hapanowicz is a great guy and most importantly honest. I was having this horrible problem in my apartment, there was a foul odor in my room and I could not find the source. I called Andy and he came out to my house to give me a free estimate. He was prompt and professional. When he couldn't find the source of the problem, he was kind, courteous and understanding. He never acted as though it was a waste of his time to drive out to my apartment. He even suggested that I buy a simple air purifier to ventilate my room, which so far, has worked!!!! I appreciated that he didn't make attempt to take my money because he knew he couldn't guarantee that the smell would be gone, since he didn't find the route cause. Andy is a real stand up guy, and I think if you have any type of odor, mold, or bacteria in your home, he is definitely someone who won't jerk you around! read more
