“I’ve had nothing but great experiences with Marks Comfort Tech. When my old furnace died, they came right away with an excellent quote and extremely fast service. Also used them to install central air, which was also very fast and affordable. Now I had an issue with my AC (turned out to be my own fault) and they came and fixed it again right away. Can’t say enough good things about this company!“
