My garage door was giving me grief. I phoned Action and they pretty much diagnosed it over the phone that it was a broken internal spring and was 2 weeks delivery. They recommended installing just a regular spring for 1/2 the cost. I also had them install new weatherstripping. The service guy showed up on time, explained different things to me and showed me how to maintain the garage door (who knew that you actually had to lubicate hinges, rollers, etc). They we professional and their diagnosis was spot on. The door has worked flawlessy for the past year.
