Indoor Air Quality Solutions, IAQS did a good job. I had a tenant who was complaining about mold. I needed to get it checked out so I called Indoor Air Quality Solutions. Lydia and John were very easy to communicate with, and they were very informative. They came out to check out the situation and found mold but were able to determine it was caused by the tenant. I was pleased with the attention they gave to the situation. I recommend them. They were great, and I'm very happy with their work.
