My garage door opener would only blink at me and would not lift the door. Trevor Rickson showed up from Precision Door and consulted with me on a possible bad conductor or a faulty motor. After a test ruled out the conductor, I opted for a new opener (mine being 16 years old). Trevor had it installed within one-half hour. The new one (the PDS 800) is super quiet. Trevor was very polite and professional – I’d ask for him again when I next need service. I’m completely satisfied with the service I received.
