Tim, the technician had…read morethe best customer service, he was pleasant, engaged in conversation, and knew exactly what he was doing. This is a new company start up. We were not concerned they were new because it is part of Mr. Electric, who we use and trust, and pricing is very good compared to other small type businesses. Their customer service model carried over to All Systems Go! I recommend their value, and quality. Use them, you will not be sorry! Rich Oliver

We have been a customer of First American for 10 years and AAS HVACR serviced our house a couple of…read moretimes. Unfortunately this time their service was poor. Let 3 messages last week to ask a question and no return. Today paid them $208 for a line modification and since they were not able to fix the outside unit asked to check the attack and although I asked them to be careful, one of their young employee was not careful and had his feet through your ceiling. I am glad that he is okay but instead of wait to talk with me they just drove off and after call twice and ask to talk with the owner have received an unreasonable email. I try to support local firms but this type of pos sale is extremely poor. Waiting now for first American claim resolution, but based on that management style I do not want this company in my house anymore.

When I asked them to come back they said they could not show favortism and would be next available. I can assure I have not received any favortism. Also, they cannot seem to give me a time. They are rude, condescending and incompetent. It is impossible to speak to a person. They are quick to send rude and nasty texts but will not give their name. The text number is 423-251-2442.
