Major Mechanical was recommended to me by a friend.
I called to make an appointment for my boiler to get looked at before winter, since I was having difficulty last year. He arrived on time; I showed him where my boiler was located. He checked it from top to bottom, he was able to diagnose the problem within 10 minutes. He explained what he found, the price that it would cost and what he needed to do to fix the problem. He told me he had the part and asked if I wanted to move forward or set up another appointment. I said if he had time to do it, then do it right away.
He was very friendly, polite and he even cleaned up after himself. Highly recommend!

The best in the area! Major Mechanical was able to figure out what was going on with my AC and fixed it quickly! I was impressed with his response time and knowledge, and he explained exactly what he was doing. I appreciate everything! So glad I made the decision to call!
