Professional, Knowledgeable, and Efficient

Thank you for jumping on this for us and reacting super fast too. The Sonos Tech you sent was terrific. Very professional, knowledgeable, and efficient. He sourced the problem quickly, made the fix and tuned up the Sonos in both rooms. We plan on using Granko for any future home entertainment needs in the future and will refer whenever possible. Great work!

What can I say? They’re great! I highly recommend them.

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.
