Thermo Cool Mechanical

We've used Thermo Cool a couple times since purchasing our 8-year-old condo, two years ago. This company is one of the contractors recommended by our condo. They were here this week to investigate a persistent annoying noise coming from our fan coil unit. The technician was prompt, professional, and thorough. He was able to rapidly identify and fix the problem, explaining everything as he worked. (The issue was a loud "water hammer" noise every time the cooling water valve closed, at the end of a cooling cycle. A slight adjustment to the opening position of the valve stopped the sound). No attempt to "upsell" me on unnecessary parts/services (which I have heard other companies try to do), and I think that $160 for the first hour of work is reasonable for downtown Toronto.
