Terrible A/C units& terrible service. I have a quality home that insists they only use quality appliances and companies. Chas Roberts a/c unit has been completely unreliable going out twice in a year. I had them come do a maintenance prior to the summer just to be safe, the guy said both units are in great condition no problems. 45 days later - guess what? Yes, it went out again. They will be here tomorrow and how would I like to pay for it? Really? Why the heck did I pay you $298 to tell me it's great 45 days ago? Here in PHX there is nothing more important than your A/C unit - go with the best and this isn't it.
