I called Overhead Door on a Wednesday afternoon, described my problem the best way that I could, and the gentleman on the other end diagnosed the problem while I was on the phone. He had a technician out the next day, and he confirmed the original diagnosis and went straight to work. In one hour he had the overhead door working beautifully. Sending the bill in the mail. I would highly recommend this company based on my experience. The technician, Patrick, was excellent in every way. Well mannered, professional, and efficient. Thanks so much.
