The guys from Mechanical Man, Inc. were both very nice and pleasant to work with. The office staff is nice too. I've already recommended them to other people. I called Mechanical Man when my furnace broke. It turned out to be a broken plastic tube on the exhaust tube. The first guy tried to fix it but a week later it broke again. So a second guy came out and replaced the tube. At least they didn't have to replace the whole furnace. They told me I had a few more years to go before I have to look at a total replacement. For that I am grateful. It's no fun to spend money on broken things in the house! I am glad I called Mechanical Man, Inc. and will continue to recommend them. They are nice people.
