I was referred to Four Star Mechanical Services Inc. After contacting them I hired them to install a floor furnace in my home. While they were doing that I also needed a wall furnace installed and a pipe repaired under the house. They accommodated me with short to little notice and did the two extra jobs with zero complaint. I have no complaints about the job they did at all. They were very accommodating and courteous. The work itself of course could be somewhat noisy but you can't do anything about that. they completed these jobs in a timely manner and were very tidy about their work. If I needed this type of service again I would definitely give them a call. I gave them an overall 4.5 star rating because I left a 1/2 star for improvement, because, well no one is perfect.
