The technician, Robert Helton, was very pleasant, helpful, and professional. He repaired the garage door opener expeditiously and explained why it hadn't worked properly. He also checked the chain mechanism and the door itself and showed me how to manually work the door should I need to do that in the future. I was very pleased with this repair work.
Good customer service is important for any product, but it is especially important for the class of garage door openers we considered. We looked primarily at models designed to be installed by a homeowner, not a professional. Even if you consider yourself to be pretty handy, you are sure to have questions at some point along the way. As such, we looked for companies that respond to all inquiries as well as for resources, such as a downloadable manual, to help with installation.

First and foremost, a garage door, by design, contains springs designed to balance your door and make it easier to lift. Those springs are under incredible amounts of tension. If a spring breaks or is improperly released, it can cause incredible and potentially fatal injuries. Keep in mind, when working on a garage door spring, it is likely that your face and head will be close to it, meaning that your most sensitive area will be in the direct path of the released spring.
