Here's what our customers have to say:
"Great family business, highly recommend !"
— Brian Gill
"We met with Thom more than a year ago to discuss installing a transponder capable of ADS-B in and out.  All of the instruments and radios in our airplane were either original from the 70s or over 20 years old.  We were ignorant about the newer electronics available and Thom spent quite a bit of time educating us on various combinations of Garmin instruments that may serve our wants and needs.  We wanted to upgrade some but not all of our panel, but also didn't want to waste money on certain equipment now that will be wasted in the future if we upgrade the panel further.  Thom helped us strike that balance.  We are VERY happy with Thom's shop's work, their integrity, their communications with us before, during, and after the work.  It's been a great experience and we would highly recommend them."
— Janice Franks
"For my money and for my situation (e.g. a legacy autopilot in a retrofitted glass cockpit) there is no one better. He's not cheap but quality rarely is. He will take the time necessary to follow your issue to its conclusion. Recommended without hesitation."
— Peter Sloan
“Thom is an outstanding technician with incredible customer service skills. Would, gladly, recommend Thom Duncan Avionics to any pilot!”
— Russell Betcher
“Excellent service—5 stars for sure. I had a problem with the ads-b downlink on my RV. Thom and his staff corrected the problem, which required additional wiring behind the panel, in one morning. Pricing was reasonable and most importantly: "It was done right the first time".
— Gene Wells
