I talked to several companies about my heater, and none of them were willing to fix the unit. They told me that I needed a new one, and I knew that was not true. Then, a contractor told me to call InMotion Mechanical, Inc. Salvatore, their service tech, was crazy competent! He knew exactly what to do! And, he went above and beyond for me! He replaced a couple of parts, and the unit was good to go! I would unequivocally recommend InMotion Mechanical, Inc.!
