Recently we had a Heat pump installed in our master bedroom and the job went very well. Our salesman Matt focused in on the product we wanted and made a solid pitch to provide us with what we requested and more. The crew of Joe, Jordan and Francisco were punctual and professional. They provided a quality install and left no mess. Based on our experience, I would recommend AirZone for any Heat Pump installation. Thanks boys!

Kudos to the installation team of Felix and Dylan. Arrived on time; explained the process; and installed the Amana inwall units in a professional manner. Also took the time to explain the remote. Recommend this team for future installs. Taylor Lewis was a delight to work with. Teamed up with me to order the units and work with me throughout the process. I would recommend AirZone to anyone who is looking for A/C installation and service.

The Airzone representative was very efficient friendly and quickly discovered the cause of our problem. He quickly got me a quote to repair the problem.

Putting 5 stars purely for the service! I haven't actually gotten to test the air conditioner since it hasn't warmed up enough yet but I'll update once I do! Everyone that came into my house or I interacted with on the phone was extremely friendly and respectful. The guys who installed my AC were thankfully very patient with me since we live in a condo townhome so we had to be very careful where to install stuff and where they could secure stuff. They came up with a great solution that the condo board was totally on board with so I greatly appreciate it!

I am extremely pleased with AirZone and in particular Max. Our furnace was red tagged by another company and I had doubts of its legitimacy. Max completed a visit and confirmed my suspicions and was able to reverse the red tag. I will be working with the sales team to discuss purchasing new equipment in the future and so far the vibe is good (not pushy).
