    "Sales and installation was great. Scheduling was a bit of a hassle. It seemed I had to pester them to get any communication from them to get the project moving. I get that they're busy, but radio silence made me suspicious."

    "It s hard to find a dependable heating service company like these guys! I don t normally write reviews but Carnot Heating really answered the call! After a hose broke overnight I woke up to almost 3 feet of water in my basement and my boiler was completely flooded out. My regular service company tried to sell me a new $6000 boiler and after second and third opinions I decided to use Carnot heating to repair my boiler instead. They went above and beyond and easily provided the best value for service. In the end they replaced my burner unit, circulator, air vents, combustion chamber, gaskets, and did a thorough cleaning with oil filter change. They even cleaned off the rust on the outside and touched up the paint! Chris and Mike are honest hard working guys and very knowledgeable experts. They easily saved me thousands and I will continue to use them for all of my future service calls!"
