I called Arizona's Dukes of Air and they were very responsive. Dustin showed up, diagnosed the problem and offered options. Dustin temporarily charged our AC system while we waited for a new installation. On the day of installation, the crew (Manny and Luis), called beforehand and arrived on time. These guys were awesome! They were both professional and very knowledgable. Thank you Arizona's Dukes of Air, we will be referring our family and friends to you!
