We have been customers of Arizona Refrigeration for many years. Their prices are excellent, and their service is simply top-notch. Whether they're doing regularly scheduled system checks or responding to the rare issue with our unit, their service techs and office staff are unfailingly polite, efficient, competent and friendly. They don't push us to buy things we don't need, and always answer quickly and fully any questions we have. I would heartily recommend them to anyone who needs quality care for their heating and air conditioning systems.
