What a shop. I was approaching the end of the long warranty the shop provides after a rebuild when a thermostat issue sent me in. After repair, Drew and team noticed a small leak and took extra care to fix it. Then they found another, and fixed that. Didn't charge me a dime. MJM is the only shop I'll ever visit.
