We had an excellent experience with AirZone. From start to finish, everything was smooth and professional. Matt was fantastic as our first point of contact. He provided us the necessary information for us to make a decision on the HVAC unit and was responsive to our requests for amendments. The installation team -- Stephen and Jordan -- were efficient, courteous, and knowledgeable. We highly recommend AirZone.

Airzone has been a pleasure to deal with! Matt took his time and explained the different products and the website backed up everything he presented. Sam in the office was a pleasure to deal with while booking the install. The technicians did a great job installing and cleaning up after themselves. Fantastic local family company!

Outstanding work. Joe and Francisco supplied and installed 2 new air purification systems and a humidifier. They took the time to fully explain how each of the 3 systems worked, and left the area cleaner than before they started. Well done!

We have got our Heat pump installed and this was a great job done by Graham and Anthony. They know their job and explained all questions and I learned a lot from them too :-). Very professional attitude, they listen and I found them very patient plus they are problem solvers, I mean it, problem solvers. They installed an Ecobee thermostat for free! Highly recommend their service.

The Airzone technician that showed up to repair our furnace was very friendly and professional. He explained exactly what the issue was and what needed to be done. One of the nicest services techs we have ever had. The follow up from the office was quick and concise. Definitely going back to Airzone for any future HVAC needs

Our furnace broke down one night in -20 weather. Airzone sent someone quickly and the services provided were great. We dealt with an employee named Rob. He was very professional, knowledgeable, and provided a great service. He diagnosed the problem immediately and presented solutions. He also explained everything really well.

Had maintenance service done on my 6 year old York LX furnace. Our service person Rob inspected and fixed a couple of things that the original installers missed. Very happy customer and will be using Airzone in the future for all my HVAC needs.

Furnace stoped producing heat. Called in the morning, tech came out that afternoon and fixed the problem. Will need some follow up work and fully explained what was needed. Great service, value for money and would absolute recommend.

Couldn't be happier with the service I received. I had a faulty Honeywell thermostat and Airzone was able to recommend and provide me with a brand new Ecobee replacement, fully installed for $395. Jordan the installer was very helpful and walked me through all the operation. All is perfect now and I completely recommend AirZone for anything like this.

I recently had AirZone conduct annual maintenance for my furnace and heat pump system. The hvac tech, Rob, was very knowledgeable and thorough, and addressed all of my questions. I couldn't have asked for a better experience.

AirZone has been great to work with, from the front desk who answers calls, to Matt who came and assessed my needs and gave me quotes, to Jordan and the install crew, everyone was friendly and extremely professional. I went with AirZone because not only did they provide competitive prices, but they are local and their approachable professionalism made them stand out over the bigger companies. Highly recommend.

Great experience with Airzone, to replace my 20 year old furnace. From the initial technical evaluation of the old furnace, to prompt and efficient installation of the new furnace, plus any follow up concerns/questions with new furnace were acknowledged and dealt with professionally and kindly. I would highly recommend Airzone.

I was squeezed in at the request of a friend. They arrived during the time they said. The service provider was efficient and personable, and explained things in terms I could understand. It was amazing to have my issue fixed on-site with no up-selling or pressure. Would absolutely recommend your services.

Last summer, my AC stopped working, and AirZone sent a technician, Diego, to my place the very next day. He fixed the issue at a very low cost – amazing! Today, Diego came by to check my HVAC system, and once again, he did an outstanding job. I’m keeping AirZone on speed dial for any future HVAC needs!

I think AirZone HVAC is an amazing company. The service is really high quality. Rob was so pleasant and professional when he came to do our yearly maintenance work for our heating pumps. I can't say enough about their quality work and the service that AirZone HVAC provides! It is so refreshing to have these types of companies around. Thank you Rob and AirZone HVAC!

Long time customer, AirZone previously installed a new gas furnace and central air. Recently had my yearly service contract updated, my Tech (Abdula) was on time and explained everything in great detail. You can't go wrong with this company.

I recently contacted AirZone to schedule our 2nd-year free maintenance appointment for our HVAC system and was booked right away. Samantha and Chelsea were helpful and professional.

Their technician, Rob, performed the maintenance and was very pleasant. He was approachable and answered all my questions thoroughly and patiently. I'd be happy to have him back for our next appointment.
