M & M Heating and Cooling LLC

After years of dealing with M&M, I have lost all confidence. The technician who attempted to service my furnace told me multiple times that my smart thermostat was the problem. He boasted he had thirty years in the industry but would only refer me to chat rooms if I pressed for a better explanation. As has since been confirmed by a separate HVAC professional, the smart thermostat was only indicating a problem with the furnace itself. M&M charged me each and every time they attempted to service this furnace, and charged me to replace the working thermostat. Still, when the furnace failed hours after their latest attempt, I contacted their emergency weekend services, but was never called back. My furnace is functioning now after minimal service from a separate HVAC professional, and I trust the advice they have given me about the longevity of the system.
