Ron is the man! Heater stopped working, house got down to 42 brrrrr, called Ron, he came 15 minutes later, diagnosed the problem, got the part, replaced it and the heater was working as new all within an hour! Couldn't recommend M&M more for anyone with heating issues. Thanks Ron!!!

I’ve used M&M twice now. Once for my wall heater and the second time for my tankless water heater. Arrived within an hour both times, fixed the issue, and reasonable prices. Will use them again!
