Dean Mechanical Inc responds quickly and gets the job done. I own a restaurant and had an exhaust fan quit working. I called Dean Mechanical Inc and within an hour and a half, they had it up and running. I recommend them because they are prompt, courteous, and they don't overcharge. They take care of the maintenance of our refrigeration unit and our heating and air. They keep everything running smoothly. They offer fantastic service. I recommend them all the time.
