I had a problem with my garage door opener and Chris and assistant came by the next morning and very quickly diagnosed the problem and replaced some parts and got it working properly. Helped to replace batteries and program the remotes as well. He also mentioned that LED lights in the Opener sometimes interfered with the signal to the built-in car remotes (which we experienced). Replaced with non LED lights. Found Chris to be knowledgeable, helpful, straight shooter and someone you can trust to do a good job. Highly recommended.
