The two guys who came out from Francis Air Conditioning were great. They came in and looked around, explained what they would do. It was a mold issue and he wanted to put sanitizer in the fiberglass. He was just very informative. At first he gave me a quote that was way out of my league, but then he gave me a 15% discount which brought the price down to something I could handle. Then they went and did the work. It was all just one big ducts, so it only took them a couple of hours. Then they put the vents back up. I got a card from them and will recommend them if I know anyone looking for this kind of work. They were very thorough and cleaned up after themselves too.
