Best Heating System Working in Phoenix AZ

These guys are absolutely ROCKSTARS!! When my AC decided to break down, they were at my door with a portable AC to keep my family cool until they were able to install the new one on the roof. Very clean, professional, and very friendly. I highly recommend them to anyone who is looking for any HVAC services. Forever a customer!

Had an energy audit done with reeis. They're were very informative and helpful in find out what I wanted to know in order to improve my energy efficiency

We have used Preferred Air for both a mini-split installation (2020) and they just wrapped up replacing the whole home A/C system and I couldn't be more pleased. We got multiple bids for both projects from companies large and small and each time Preferred Air was honest, had a great price, great products and quality service. Their people are prompt, clean, courteous and just plain ol nice. I wouldn't hesitate to use in the future and will definitely use for yearly maintenance.

Was beyond awesome. SHANE WAS Early!! My place was 82 and climbing. Got it fixed quickly!!!

Today, this company provided me with an exceptional repair service. Their technician was very knowledgeable, personable, and upfront as he addressed my maintenance for central ac and dryer vent cleaning. He didn't try to upsell me and gave me some advice on maintaining the good working condition of my system. Thank you very much!

Our home owners insurance sent these people to us and we were totally ripped off they did not fix the AC they used the wrong part and we were charged for 11 pounds of freon when our AC only holds 5.1 tried resolving this matter with them they offered us $200 of are $715 bill The Tech that performed the service released freon into the atmosphere just got done filing report with EPA News channel 3 is next Do not use these people

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.

If you need A/C pros, these are the folks to deal with!
