In 2006, our apartment building's steam heating system was in bad shape, long neglected, run by an uninformed superintendent. We hired Cordell, and Aron took a personal interest in bringing the system back into a state of good repair. He recommended suitable additional controls, fixed the 60% of rad traps that had failed, fixed the 100% of F&T traps that had failed, tuned the system, and worked with me to ensure that we had the most efficient system possible. Our gas bill is half what it was, the system is now quietly reliable, and residents are happy.
Aron knows his stuff. (On the other hand, some of the guys working for him are a few coupons short of a blender.) But if Aron's your guy, you're in good hands. He's reliable, knowledgeable, and keeps his commitments.
Cordell is not the cheapest contractor; but you get what you pay for. (Or as my Newfie roofer said 25 years ago at my house, "you pays for what you gets." Pay a little for a bad job, pay a lot more to have it fixed.)
Overall, we are happy with Cordell and continue to have them maintain and service our heating plant. (25-suite apartment building, downtown Toronto).
