Best Full Design Services in Phoenix AZ

Received excellent service from Shawn and Andreas with Howard Air today. They took the time to explain to me some things about my new system I wasn’t otherwise aware of. 100% satisfied

We had a RO system drained and new filters changed as well as did a check on soft water system.
The technicians was fast, thorough and clean.

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!

Work was done to add insulation to attic, with concentration on void spots causing heating/cooling leakage, including a skylight which was not insulated in the attic. Also a heating duct was added to the laundry/extra bedroom to replace poorly performing heating/cooling to that room. Attic ducts and inside vents were also resealed. Installation was done in one day as scheduled. The cost was reasonable with an estimated less than 10 year payback.
The estimator and job manager were very friendly and personable and explained in detail the problems we had and the work to be done. Overall, we are very satisfied with the work and the results to date.

I would highly recommend and use this company again for any electrical work. I am very pleased with the quality service and affordable pricing they provided.
