Best Central Air Unit in Phoenix AZ

Reliable, affordable and courteous. I recommend Mountainside Air for your HVAC system service

Airzona installed our unit in the middle of the summer they were a blessin. Gerald and his guys made us feel valued as customers and that is always appreciated it. Fast, reliable and affordable! Thank you Airzona.

We needed an A/C damper installed. Derek came right away, he was reasonably priced and did a great job. Very professional, highly recommended.

They were terrific! We’ll recommend them to everyone!

I got a Technitian named Lenard(I guess that's the way his name write) He was so profesional and taked almost all morning to fing the root of my problem. I apreciate you still have Technitian like him that takes the time to solve the issue.

Katie and her team were wonderful they were able to find my coil for my ac unit and get it installed within 2 days. Katie and her team are very knowledgeable and gave me fair and honest pricing. I wish I would’ve went to them sooner! They’re fantastic thank you B3!

They did a great job. Would hire again.

John is one of the best technicians I've ever met. He is knowledgeable, fast, friendly and precise. I would recommend this company to everyone, ask for John, you will be happy and cool!

Excellent service very helpful and friendly! Definitely recommend to any friend or family member Daniel was quick to come out and check out my AC problem!. He had a new unit installed by the next day! My AC was working within hours great service!

I needed a very specific piece for my range and appliance repair bros helped me order it and overnight it. They were incredibly helpful and went above and beyond to help with my request! I would definitely contact them again for other needs.

Great company. Very professional. Will definitely be calling them again when needed!

We purchased a new home and the AC wasn't cooling. We knew who to call because A1 Heating & Air llc had done a great job in our previous home. They made scheduling simple, the tech arrived on time and quickly repaired the issue. Overall a great experience.
Highly recommended to all friends & family.

Thomas was early to our appointment. He was absolutely professional and courteous. Took the time to show me what exactly was causing my AC to no perform at optimal levels as well as giving me tips that I could do on my own to make sure things flow smoothly till my next tune up. Can not recommend these guys enough.

Excellent customer service from the office to the techs, they are the best I've dealt with in many years, thanks guys!

RJ, my technician, was incredible! He checked my filter inside the house and also went above and beyond to make sure that EVERYTHING in my A/C was working correctly.
He was awesome. He was knowledgeable and friendly and he answered all my questions about my unit.
Custom Cooling is lucky to have such a great person working for them!

We really appreciated the ease of setting appointment to getting our wine cellar inspected. Professional service! Will definitely continue to use their services.

Thank you so much for the fast response

Outstanding, very informative, professional service, highly honest.
What more can I say but this A/C company anyone needs; forget the others

The A/C had issues. Earl came over and replaced a part and the cooled air began to flow!!! They are now on my who do I call list.

Had our yearly tune-up. As usual technician was professional and informative. Answered all of our questions. Technician made suggestions but not once was high pressure or alarmist. Appreciate good customer service. We are in the market for a new system and will definitely make Scottsdale Air our go to supplier.
