Based on the excellent job they did for us recently fixing a water heater emergency we have asked them to put us on their regular maintenance program. Service has been on time or early, Devin, our service tech, was courteous, polite, listened and explained things clearly and most importantly, got the job done and the problem resolved. Lily, in scheduling, was empathetic and knew how to pull the strings and juggle techs to get them to your home quickly. Lastly, prices were fair and reasonable in my opinion. Thanks Devin, Lily and MM Comfort Systems!
