HVAC reviews in Phoenix, Arizona

Thank you for coming quickly to the rescue with our air conditioner and heater needs. Great customer service.

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

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.

This was the easiest, most straightforward interaction I've ever had on an A/C system. Great value and also great quality work, tidied up any mess and checked back after completing the job to ensure all was running smoothly ! Awesome experience all around.

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!

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.

Excellent service. Ulises was great with communications, scheduling, cleaning up and explaining our new heat pump. Will definitely call on them again.

I noticed some water on my AC filter yesterday and reached out to Ulises. He came out ahead of the schedule today. Fortunately, it was a small issue with the clogged drain. He did a drain flush in no time. What's wonderful about him is that he is polite, transparent and knowledgeable. He even showed me the tools he used and where to get them. He also shared a lot of tips and things about my unit. Ulises just got one more repeated customer :).

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!

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 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.

I recently had work done to my AC unit by Certify HVAC. Service was great and very professional. They are very knowledgeable and honest. They will not take you for your money and they will go over all your options to work with you and not break your bank account. I will highly recommend Certify HVAC services to everyone.

I recently had the pleasure of using Certify HVAC for our air conditioning needs, and we couldn't be happier with the service we received. From start to finish, they exceeded our expectations in every way possible.
First and foremost, their punctuality was impeccable. In today's world, where it seems like timeliness is a lost art this company restored my faith. Not only did they arrive exactly when they said they would, but they even managed to fit me in earlier than expected. The technician was able to find a window in their schedule and accommodate our urgent need for AC repair.
The technician who serviced our air conditioner was extremely knowledgeable and professional. He diagnosed the issue quickly and efficiently, explaining the problem to me in a way that I could understand without talking down to me. Even more impressive was the fact that he was able to identify and fix the problem without any additional charge. This level of honesty and dedication to customer satisfaction is truly commendable.
Additionally, my wife and I were pleasantly surprised when the technician provided two mobile AC units to keep us comfortable while the main unit was being repaired. This thoughtful gesture went above and beyond our expectations and made the whole experience even more pleasant.

Furthermore, the pricing was fair and transparent. There were no hidden fees or unexpected charges. Certify HVAC company provided a quote upfront, and the final bill matched exactly what was discussed. This level of honesty and integrity is rare in the service industry, and it's refreshing to find a company that operates with such transparency.

Overall, I highly recommend Certify HVAC company for all of your air conditioning needs. Their commitment to excellence, punctuality, and fair pricing sets them apart from the competition. We will definitely be using their services again in the future, and I encourage others to do the same. Thank you, Certify HVAC and personally Ulysses for a job well done!

It has been such a pleasure working with Ulises at Certify HVAC. He came to our rescue by helping us replace our AC unit with a new and appropriate system. He was thourough to find out that the old unit was the wrong size and insuficiant for our home. He exceeded our expectation when he calculated and implemented a new and appropriate system that is more efficient and sturdy enough to cover our entire home with fresh and freezing cold air. We love and enjoy our new AC and are sleeping so much better now. I wish we would have found him sooner. Ulises is such a nice, knowlegable, and honest person. Thank you Ulises for everything. We are so blessed and honored to know you and entrust our home to you. We recommend everyone to give him a call for your AC needs.

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!

We had a great experience with Certify HVAC. Ulises was so kind and helpful to us. He took the time to make sure we were properly educated about our HVAC unit and what was needed to fix it. We appreciate you and look forward to working with you in the future!

Ulises did an excellent job with replacing the air conditioning and heating unit in our house. He took the time to do the job correctly. He even came back a few days later when a problem arose (not from his work, but from the work performed by the previous owner's people), to correct that issue. It's a family owned business and he and his father were very good, very professional, and very nice. They were also VERY reasonably priced, in fact a couple thousand dollars less than other quotes we received. I can highly recommend them for any air conditioning or heater needs!

Ulises is knowledgeable, professional, courteous, and most important in an HVAC contractor, entirely honest. I've been using and referring Certify HVAC for years. My friend was told by a big name HVAC company that her unit was not worth repairing and needed to be replaced. Ulises replaced a capacitor and had it running later that day.

I had services at my home on 7/11 for AC. Ulysses has great/professional customer service very friendly, & knowledgeable. His prices are reasonable. I would recommend his services to my friends and family. The most I will remember about this service is his hardworking/honesty!!!!!!!!!!!!.
