I have two units near ASU in Tempe and the A/C wasn't working. A friend of mine recommended Cornell. Cornell knows what he's doing and beat the big companies in price by a lot. The big companies were trying to get us to buy 2 new units at a 200% mark up. Cornell got the units working perfect. He also did a clean up on the units that made them more efficient. Cornell is now my go to AC guy. It helps he's friendly person and a good all around guy. He's the best in AZ!

We highly recommend CJB Comfort!
CJB Comfort is our new go to HVAC service provider, and I am recommending CJB Comfort, to everyone I know in Phoenix.

CJB Comfort worked to identify the issue with our existing AC, and offered a very fair price to repair it, without tacking on extras. Later, when we established it was more worthwhile to replace a different AC unit we own, over fixing it, CJB offered very competitive pricing, no pressure sales tactics, was very detail oriented during the install, and worked late into the night to make sure our unit was installed on the same day.

Cornell is a great guy. He is very professional and proficient at his job. He installed a new wet section on my evaporative cooler and did a great job. Also did a service on my AC unit. He arrives on time and treats you fairly. I highly recommend using this company

Cornell is amazing!! I’ve referred so many of my friends and family. We heard a loud sound coming from the ac unit. We had a veteran owned and run company come out and say we needed a new ac unit, and if don’t act now, the prices will increase in the summer, it was June at that point. Had a second opinion, they took pictures, went over the diagnostic readings… but same conclusion, we need a new ac unit. Our third consult was Cornell, he fixed the problem for $350 and our ac has been working great a year later! He really knows his stuff and you can tell he just wants to help, and not scam you.
