Everything looks great!

Thank you again for fitting this project in last week. The crew was awesome and everything looks great!


Did a terrific job

Imagine my surprise as I walk into the entry of our small place in town and find a couple big Starlink boxes !

On another note Clancy did a terrific job of all the rest of the network stuff today. Really a smart guy

Let me know when you want to schedule the rest


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!

Great Job Today!

Your team did a great job. The music is amazing. Nick was also very proactive and helpful setting up DirecTV for success by initiating a diagram to follow. I really appreciated it!


Really great service – very much appreciated

Just wanted to send a note to thank the Granko team and Clayton in particular. He came by this morning and got us going, handled things with Comcast (and ever offered to take the 2 Comcast modem/hardware items we had been sent back to the UPS store to get them back to Comcast). Really great service – very much appreciated.


Wishing you and everyone at Granko even more success than you’ll obvious have in 2021! 

If there was ever a moment when my faith in American business was restored, it was when Nick Johnson walked in the door to enlighten and install the new television gifted to me by my sister—an amazing thing unto itself. I cannot forget that my dear friends Kelsey and Erick gifted the installation on this project, and that, too, was a beautiful thing.

Although in the late 1970s I was on the first wave of the desktop and microcomputer revolution, and I can master a new app pretty quickly, I am a complete and total idiot when it comes to television, radio, video: all the fun stuff. I could no more turn on a television and choose a station outside Turner and the top three broadcasters than I can run a marathon. “Clueless” would be a compliment.

Nick, with intelligence, patience, kindness, and expertise, brought me into the twenty-first century. And I so appreciate it.

But it was more than that: he made sure that Comcast did the right thing. Nick followed through to the bitter end with them and the results were astonishing. At one point, I saw the Comcast guy (who had no clue what he walked into) and Nick outside near the Comcast van in a long discussion about something.  I was the beneficiary of that conversation, in which Nick pointed out that I had been charged for years with services it would’ve been impossible for me to enjoy as I didn’t have the equipment and could never have known HOW to use it if I had it. Nick’s conversation, and his insistence on being present until the changes were implemented, saved me hundreds of dollars a month.

Further, he made sure I could point the damned clicker at the TV and get this or that or the other thing to happen! After I gave up feeling like an eedjit, I realized his patience had been the key. He didn’t condescend or even giggle (which he so could have!) and he made sure I could manipulate the monster before he left after the second, follow-through appointment.

All of this is to say that Nick truly embodies the kind of employee that every business—large or small—dreams about. He is an asset to your business in every way: from his open, friendly walk through the door to his expertise and attention to business detail. He represents Granko beautifully. What a fortunate firm to employ him! Don’t tell him, of course…wait, yes, maybe you should. Add money and tell him.

I also want to thank Robin for her communication and follow-through. Delightful, and right on top of everything, especially when Comcast tried an end-run around Granko by making appointments without telling you or me. Thank you for sending him to handle much more than the installation of a home system. I wish I had some inside and insight from my misspent youth and could direct you to a huge black ops contract, alas!

Wishing you and everyone at Granko even more success than you’ll obvious have in 2021!

I am sure that we will be calling you again.

Thank you Robin for sending Anthony. He was mellow, patient and helped us with all our little tech problems and activated my apple tv and saved me the application. I can send it back to Amazon.
I am sure that we will be calling you again.

You guys are impressive!

Thank you, I sincerely appreciate everything, I’d like to tell the whole state about the courtesy, professionalism, timeliness etc.. you guys are impressive!


Incredibly patient and determined

Thank you so much for sending Clancy over.  He totally fixed a vexing email problem, and was incredibly patient and determined in doing so.  I’m so glad you have someone with his skill set on the team – incredibly helpful.


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.
