I hired Air-Zona Air Conditioning a year ago. They told me to replace my system. I hired another company for second opinion. They were able to fix it for 1/20th of the estimate Air-Zona had quoted. I wouldn't call this company back or any company that suggest replacing my system. I suggest you do the same. Just because we live in the Phoenix heat doesn't give them the right to take advantage of us. Integrity will always earn respect and repeat business. This company don't deserve my repeat business.
