We hired them to install a basement in-floor heating, main floor - in-floor heating, split unit air con, new (replacement) rads on 2nd floor and a humidifier system. This type of work is not typical of the work they do. They work mostly on forced air systems. Accordingly, this review is likely unusual for them I presume. In fact, our sales rep - Darren - as we later realized and became evident - had never done work on a hydronic system. This became very evident as I note below. Further, as he left the company, the ball was somewhat dropped on our job in terms of management. Eventually, it was completed. The owner - Mathew - came out to view the job in order to push along the work when our contact left. I would trust Mathew to ensure a job is completed. He appears to be someone who stands behind his word. We have since purchased a humidifier from Aire One.
The price we paid for our job was competitive. It was on the lower sides of tenders but not unequaled. Estimates ranged from about $35,000 to $45,000 for our scope of work.
The work was contracted out which resulted in some 'broken telephone'. There are some cold spots in the floor in key areas including in front of basement kitchen sink, bottom of basement stairs and one basement bathroom. These problems are not fixable due to the nature of in-floor heating.
Our air conditioning (split unit on 2nd and main floor) work as expected.
Aire One has a very large of products ie boilers, indirect water tanks, etc which was a factor in our decision to use them.
Overall, I would recommend using them.
