My only experience with them is that they parked in front of my car for more than 2 hours so I couldn't leave. I figured when I went out and started my car and saw the guy that it would give them the hint I needed to leave and that they needed to move their van. I even saw the guy when I started my car and asked him 'how are ya' only to have him not respond and continue into my neighbor's house where he was working. After twenty more minutes I had to repeatedly knock on my neighbors house to finally get an answer (we're in small townhomes so they were right by the door) and JM mechanical's response wasn't 'oh we're so sorry' it was 'oh'. If my experience is any indication of how they treat customers they must be very inconsiderate. I was looking for someone to check my furnace and now I definitely won't call them or recommend them to anyone. Not impressed at all.
