After 6 years owning my house my garage door finally needed repair because one of the rollers had fallen off. I know the owner and immediately contacted A1 to set up an appointment. They offered to send someone the next day but I needed to wait until the day after so I could be home and they setup a window from 8am-10am. They were supposed to call in advance when the technician was on his way but I didn't hear from them. However, he showed up around 9am, right in the middle of the appointment window. Ed was friendly and thorough, checking the entire door, cables, etc and even replaced my burned out light bulbs. He told me the rollers have a lifetime warranty and showed me how to lubricate the rollers to ensure the warranty isn't voided.
