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.

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.
