This company absolutely deserves all the positive feedback they have received.
Aaron's knowledge of and experience with tankless water heaters is unparalleled in Toronto. I began researching tankless water heaters months ago and appreciated his assessment of my rental tank at that time (no need to replace, but don't buy it out) and his ability to field my tough questions on the reliability of Navien's new line of tankless water heaters. He made no attempt to sell me anything when my rental system was working but he did predict an early failure of my tank. When the tank did fail a few months later, it was obvious to me who I wanted to install a new system.
I was grateful that AccuServ was able to respond quickly to my sudden loss of hot water. (Thanks Jake!) The installation of the Navien 240 was perfect, including a new, properly sized gas line (something that many contractors neglect.) Of course, by this point, I knew that the installation was going to be done properly because that is the culture of this company.
In the middle of our discussion of tankless systems, Aaron noticed some installation errors in my new furnace done by another company (the furnace was replaced as an emergency over Christmas and we did not have time to research companies.) One of the installation errors led to a red tag which forced the other company to come back to fix it.
I have now had Rahul, AccuServ service technician extraordinaire, do maintenance on both of my furnaces and my air conditioner. Rahul is the most thoughtful, detail-oriented and thorough HVAC maintenance provider I have ever had.
I am so glad to have (finally) found AccuServ. They are professional, knowledgeable, friendly and fairly priced. I would give them 11/10 if I could.
