Thanks so much to Alien Air Conditioning and Heating for the fast, honest service that you provided me. Tech Christian was just the nicest guy and explained everything to me that needed work on. He also checked to see if the part was under warranty and luckily it was. You can't find a better Company to trust in the Valley than them.. I would never give my service to any one but them. Thanks Chris

We choose George Brazil to install our air conditioning unit because of their excellent reputation. Their technician, Matt B, proves our inclination was right. Matt provided excellent diagnosis skills and exceptional service. He is the best example of how great employees make a company great.

Mark was a little late. I only mention that because he called to let us know. That was very much appreciated and showed professionalism. He asked questions, examined our AC units and diagnosed the problem in just a few minutes. Then made the repair in no time and explained what he did. Even though this was covered under our home warranty, the price was reasonable. Thanks to our experience with Mark, I highly recommend this company.

Very professional and trustworthy company.. highly-qualified employees.

Best company ever!!! I just Love them!!!

Tom and his crew are very knowledgeable and professional. I wouldn’t hesitate to use them again. Highly recommended !!

I sit near it, but don't know anything about it. Guess they keep Sky Harbor cool/warm.

Premier did the first of my 5 evaporative coolers 7 years ago. They have are fast, efficient and very responsive whenever there is an issue. Their coolers are made from stainless steel - so no rusting out, ever. Their technical support is excellent. Prompt and always on point.

5 Stars! Sometimes I go there and help them with their EMS items. Shortly after, I get a donation to my family's well being. They are a great business to assist in helping both commercial customers and school districts save money, while ensuring their partners (employees) are taken care of!

My first experience with this company was very good. Then I called them back for another issue. Felt the assessment was very incomplete, was charged $79 for the visit and never received an estimate! When I called, she said the techs phone wasn’t working to send the estimate? They cashed my check anyway- not happy!
