"I wasn't so sure about his 41 google reviews and all 5 stars...I figured something was off. However after working with him on my Aspen ProMax1000 upgrade, I now get it. Thom is a rock solid guy and knows his stuff. He will do whatever is right to make sure your plane is exactly how you want it. My only complaint is that the word is getting out about him so any project is at least six months out.."

"WOW! The best service and competency in the industry. Thom and his crew installed dual G-5's last year and followed up with new GTN750xi this past month. Work was accomplished expertly with no squawks. Integration with my S-Tec 60-2 autopilot in my Bonanza Debonair was seamless. If you want the best installation right the first time, then Thom Duncan Avionics will deliver.​​​​​​​
– Henry Feldhaus, Google ★★★★★

"Thom and his crew did an incredible job for me in my 1964 Mooney! Professional, efficient, and cost effective. I felt well-cared-for and trust them completely. ** Upgrade to new Aspen! And it is FINE! They know what they're doing.​​​​​​​"
