I believe I have done business with Four Star Mechanical Services on multiple occasions now, they originally worked on some plumbing for me a while back and I enjoyed their services so much that I called them again for a water heater installation. Both of our service dates with them went very smoothly and I really don't have any suggestions because of the excellent service they provided me. They are very professional, hard-working, and communicate very well regarding the service they are completing. I would highly recommend their services to anyone.
