The people at Pro-Tech Heating & Cooling were fantastic. They knew their stuff, and if they had any qualms or questions, they had no problem searching for the answer, instead of just throwing parts in there to see if that did the trick. I respect their way of thinking. My furnace was malfunctioning due to a bad control port, and although it took some time to diagnose the problem, they worked hard to get to the heart of the issue, in order to figure out how to fix it. This was my first time using their services, and I would recommend them to everyone I know that may, or may not, have an issue.
