Jan. 7, 2020, Clancy Coakley, Granko AV Senior Programer, reprogramed our Universal Remote TV control. Then he integrated our audio system with the TV. Next he tweaked two Amazon Taps so they worked perfectly. Then Clancy reprogramed our upstairs AT&T TV control. He did all this in two hours for $300. Amazing! I called Robin Granko, the office manager, six days later. Granko boldly guarantees 100% satisfaction. I told Robin I was only 98% satisfied. Clancy returned Jan. 14th to tweak AV system. He cheerfully changed CNN on Universal Remote from standard definition to HD. Then he switched downstairs TV audio from TV set to ceiling speakers. It took 15 minutes to 100% satisfy me. No charge. Thanks to Granko, my AV system works flawlessly. What can I say? They're great! I highly recommend them. Ray Brown Jan. 11, 2021, Clancy Coakley, Granko AV Senior Programer, made a return visit. He tweaked both Amazon Taps so they worked perfectly once again. He also showed me how to update our Marantz audio system. Granko is excellent! I continue to highly recommend them. You won't be disappointed. Ray Brown

I have worked with Ryan Granko and team for 20 years. Both on 2 commercial installations and 2 of my own home installations. They are the best.. they don’t leave until it is working correctly. And I would have any member of his team sit down at my dinner table as a guest.
