Francisco and his team are great! My go to HVAC guys!

Scott P.
We’ve been lucky to have worked with Francisco for 8 years for our various HVAC issues. He’s provided very high quality service and excellent communication. He explains what is happening and provides clear options and prices. Many professionals have a convincing sales pitch but on the back end (I.e after payment) the quality of service/availability disappears. This is not the case with AZ tech. Highly recommend!

S S.

I had a great experience with this HVAC company from start to finish. The team was professional, punctual, and very knowledgeable. They took the time to explain everything clearly and made sure all my questions were answered before getting started. The work was completed efficiently, and everything was left clean and in excellent condition. I really appreciated their attention to detail and commitment to quality service. It’s not always easy to find a company you can trust, but they definitely exceeded my expectations. I highly recommend them to anyone needing reliable HVAC services!

Had an emergency where my HVAC wasn't cooling and he came in less than 20 min and fully resolved our issue within 30 min. He even followed up the next day. Amazing, quick, friendly service. Would definitely recommend.

Ben T.
This is second time we use Mr. Galvis from AZ Tech. Very professional, honest and hard working technician. Only recommending services that are actually needed. He changed the motor for the fan and added more refrigerant to one of the HVAC units. Always with a good disposition. Carries many parts so the repairs were completed the same day. Always recommend him to our friends. Gracias Francisco 👏👏👏

Monica R.
I do a lot myself, but when it was looking like a bad fan motor, I called AZ. Francisco confirmed the motor, then did the part I didn't want to do - ordering and replacing it. We worked good together.
