 Trustindex verifies that the original source of the review is Google. The technician was on time and courteous throughout the service. He was prepared with shoe covers as I do not allow shoes in the house. I am grateful that no problems were reported. I have been using this company for three years and will continue.

I have a grandson that I'm raising that has Cerebral Palsey and is in a wheelchair.  Anytime we have problems they always get to us quick as possible and I appreciate it. They are good people and we appreciate them.
