Our hot water tank broke down and control air was one of the first company to get back to us. They were able to come quickly to assess our situation. We were quite confident we wanted a tankless water heater. Slawomir provided us with all the pros and cons of the tank/tankless water heater. He was suggesting we should go with the hot water tank. I was actually surprised because most of the other vendors were trying to sell us the tankless, though that was what we wanted anyways. But this guy was looking out for his customer and suggested what was best for the client. We had tonnes of questions and Slawomir took his time to address each of them. After much debate, we went with just the regular water tank. Installation was done within a few hours. Everything looks great. No mess was left. Pricing is competitive. We are extremely happy with Control Air and feel confident we made the right decision with the help of Slavomir.
