Air Conditioning Heating Ventilation Certify HVAC

I can give Certify HVAC only 5 stars, I would give more. Ulises helped me out with a project that I had in mind for quite some time. The project was completed in a breeze, no stress and everything met my expectations. Ulises did a great installation job, came on time, executed flawlessly the project, left the area clean and perfect. I have to say, over the years I used many A/C companies and the service that Ulises offered me was above and beyond. I highly recommend Certify HVAC. The quote I received was very competitive, the job execution just superior when compared to many other A/C companies in the valley. I wish I found Certify HVAC earlier: would have saved me many headaches. Good job!

Certify HVAC was recommended to us by a neighbor who had a new system installed last year.
Ulysses arrived ahead of a scheduled visit for a quote on a new HVAC system. By the time he left 2+ hrs later, he didn't feel we needed a new system yet, and instead replaced a small part he found to not be working as expected.
He is very polite, very honest, and will be our only HVAC person to call for future HVAC needs!!

I really don’t want to give a great review because he will probably be overwhelmed with new customers.

Only problem was that his service was beyond beyond exceptional.

Honesty, professional, excellence are just a few of the adjectives that come to mind.

I engaged Certify HVAC to re-route my clothes dryer vent. Ulises understood exactly what to do, and even improved on the idea. Two days before the vent work was scheduled, my AC stopped working. Ulises came a day early, and identified what the AC problems were, and repaired everything. He also solved a long-time problem with wiring to the Nest thermostat.The next day the vent project was completed nicely right on schedule. Ulises is a great listener, problem solver, trustworthy and keeps to his word.

Ulises installed minisplits in three rooms for us. He went the extra mile to find equipment given supply chain issues, and also to do things like paint the line set covers prior to installing them. He is very responsive and does great work. We'd hire him again in a heart beat.

Ulises and his team did a great job installing my mini split system. They are professional, courteous and do a great job! They also do repairs and are very knowledgeable on diagnosing and addressing the problem.

You'd be well served in hiring this firm to handle your hvac needs! Ulisses is very thorough, competent, patient, and above all honest. I found this firm via Facebook, and am in the process of collecting bids to changeout a 4 ton split heatpump. My installation presents couple of unique challenges, and Ulisses has been very wise in layout and addressing options. I've seen his work and it is excellent! Very refreshing to see in a world served by mostly corner cutting, overpriced hacks. His changeouts re-use what's practical, but replace everthing that is otherwise tired. His pricing is among the best you'll find too! Also look at his bid sheet! He delivers much more for your $ in his changeouts than most. You'd pay well over double for comparable services performed by the "big bow tie corporate van" guys!

Ulises Ruiz Owner of Certify HVAC LLC is DEFINITELY the BEST! I have called many hvac services and Ulises is the best one I have called. I would highly recommend him to anyone.

Thank you again Ulises!

Came the same day! Explained everything he was doing & how to maintain the system! Reasonable prices! We were pleased!

Very professional and made us feel comfortable with the service & care we were getting.
Would highly recommend Certify HVAC
