Having CAV Audio Visual do our TV hanging and wiring was a pleasure. Not only were they polite and prompt, but the work was done to perfection. Don didn’t try to sell me things that I really didn’t need and the pricing was very reasonable. They also came back to help me set up the 4k cable box. So I give them A+ for a job well done…and they even took off their shoes, which is a big plus with me. I would definitely hire them again for any electronic needs!

Cav A/V has done several installations at my house over the years; Wired house, hung TV’s, installed Sono’s speakers and Sono’s system inside and outside and installed security cameras. The service, and professionalism is always great. Would strongly recommend to anyone looking for A/V solutions.

I have been doing business with Don and CAV Audio for years. Don installed my family room TV and also wired my entire house. I still get compliments on the TV mount over ten years later. Don has kept me up to speed with SONOS speakers and other smart home updates as well. Finally over the summer I hired them to install an outdoor TV. This was worth every penny and I was extremely happy the way it came out. I highly recommend them for all areas of expertise.

Very highly recommend CAV Audio Video! Don and his team are very talented and knowledgeable. We had them update all of our thermostats and they added home security. Don was responsive to all of our questions we couldn't be happier with the results!!
