Disclaimer: Sunrisent.com is a free service that attempts to connect customers with the right local contractors. Most of the time, we do that very well. However, we work in more than one area and with more than one company. We currently have no way to police the HVAC companies we work with as they are independent contractors of Sunrisent.com and we cannot warrant or guarantee their work. It is the responsibility of the homeowner to verify that the contractor they hire has the necessary license and insurance paperwork required in Arizona (with him) before allowing the work to begin.
