Thanks to this forum/thread, I was able to make an informed decision on who to pick for repairing my garage door opener. I went with Branch. They came out the same day, and Chuck the technician was both competent and friendly while he went about his business of repairing the opener. The price was reasonable for replacing the gears inside the opener and replacing a frayed cable. I was not even aware of the problem with the cable. He said it would have snapped in a month or two requiring another service call. He also balanced the door, sprayed the parts requiring lubrication and told me to do that twice a year to ensure proper lubrication on the moving parts. Total cost: $150.00 which includes a $80.00 service call.
I strongly recommend Branch and if you can, ask for Chuck to make the repairs. You will be glad you did.
