It is with great pleasure that I recommend Tri-Air. I have had the distinct pleasure of working with Tri-Air in the capacity of Environmental Services in a Retirement Residence Facility.

Tri-Air has always displayed a high degree of integrity, responsibility, and ambition. Tri-Air Systems are definitely leaders in their profession. In addition to their excellent work ethic, project accomplishments and their high level of efficiency, they have proven their leadership ability by coordinating and assisting in projects and assignments within our Health and Wellness, Life Enrichment, Dietary as well with our Administration Departments.

Tri-Air has an aptitude for social interaction with everyone they encounters. Tri-Air Staff engage well with our seniors, our guests and family. Tri-Air Systems are dependable and team players. Their good judgment and positive outlook ensure a logical and practical approach to all their endeavors.

I believe Tri-Air will be an asset to any organization who contracts them, and I am happy to give them my wholehearted endorsement.

Many kind thanks to him & everyone at Tri-Air!! 🙂

Dr. Tse

Tri-Air did an excellent job explaining everything clearly and answering every question

We are very satisfied with the attention to detail and thorough level of review and maintenance done to the building's equipment. I feel confident that arising issues will be handled promptly as well. Please let me know if you have any further questions.

Property Manager

Martin always does a good job of communicating any or no issues when he's on site.

He's very good at that.


TRI-AIR is at another level compared to the competition.

Condominium Manager

Your technician is a good representative for your firm. He communicated well and was very responsive to our needs.


Everything was great. He came in, introduced himself (we had met before) and went to work. He found a problem this time, sourced parts and got the problem fixed. Good sense of humor too.


Just thought I would share this (from a staff member) yesterday ....... kinda makes all the hard work worth it!“
“We love Paul, this morning we had heat!”

Staff Member

Martin was punctual and managed to diagnose the issue with the Ecologizer unit. Our Ecologizer unit had been unable to properly extract the heat and smoke from the kitchen for several months. The next day Martin brought proper filters from the supplier and the kitchen was once again a safe and comfortable work environment.


Your techs are the bomb! They were able to pin point the problem extremely fast and had it fixed pretty quickly too. They are very professional and knowledgeable.

Purchasing/Admin Manager

My experiences with you technicians has been amazing for myself and my super as well. Their knowledge and ability to explain their concerns with us is exactly what we were looking for.

Property Manager, Jan 2020

Your company did an excellent job of servicing our commercial rooftop unit. You came in less than 24 hours of our call for no heat.
