"A big thanks to Justin, for wall mounting 4 TVs and installing 2 extra antenna outlets for us. Some of it was a little tricky but he is great at coming up with solutions. The price was great and the results spectacular. Friendly, courteous and excellent communication. Thanks Justin and Hi Definition AV. Highly recommended".

Testimonial for High Definition AV

I have pleasure of writing a few words for Mr Justin Dunn and his team of High Definition AV Company. They recently installed HD television at my home and connected all the sound system, Foxtel , DVD etc. The service was excellent, his charges are reasonable or I would say below what other company charge.

He is the person who goes extra mile to help you and explain all the system as how does it work. He does not charge on minute or hourly basis will let you know a set fee in advance. He is honest and trustworthy and I would highly recommend him for any TV /AV installation and connection etc. His work is excellent.

I could not be happier with my tv installation. I had a 65" tv wall mounted. Justin was able to get it on a perfect angle which I thought impossible with the restricted space and tricky angle. I highly recommend this company. The workmanship is of a high standard and he left the space clean and even retuned my tv to an even better setting. I am beyond happy. Thanks Justin.
