  Thom and Kevin added a GARMIN GDL 69A and rear seat 6 pin headset jacks to my pristine Cessna T182T. I could not be happier with their attention to detail, devotion to doing things correctly and willingness to accommodate my schedule. Super smart, extremely well organized and able to communicate thoughts in an understandable language. This avionics shop knows their stuff. Good people!

  Incredible responsiveness. Best in class service. My Flight Director was repaired and back on line in a matter of days. Thanks to Thom and his knowledgeable staff

  Last October we were planning a trip out west and my Aspen failed on me. We have an avionics shop on our home field but they were too busy to get me in. I got a recommendation for Thom Duncan. Thom told me he was also very busy but took the time to find out what was going on with the Aspen. After troubleshooting it over the phone he gave a couple of options. One was an upgrade to the Max Aspen with a loaner due to the backlog of new units. The loaner came pretty fast and Thom took time out of his busy schedule and we were able to make out trip out west. When the Max unit arrived he again took time out of his schedule and installed the new unit. A few days ago I had a hiccup with the Aspen and again got me fixed just a few days after my call to him.

  Thom & the guys are AMAZING! They are our "go to" people for anything avionics! We've had them do everything from minor service & repairs when our transponder went out to a complete panel upgrade & we are on the books for an autopilot install in the not-too-distant future. Communication has been great throughout. He is incredibly thorough from initial quote to changes/modifications to the final checklists he uses to ensure everything is as he said it would be. From the time we dropped it off to the time we picked it up they were working on it! It didn't sit there in line. When he said I was scheduled to drop it off that meant they were gonna be working on it! I can't say enough about Thom & his entire staff! That's why we keep using him. They're top notch!

  Short-notice repair of a problematic Aspen system. Timely, good communication. No complaints.

  I have known Thom for almost 30 years and cannot say enough about his knowledge and professionalism when it comes to avionics installs and repairs, not to mention he is a heck of nice guy. Duncan Avionics is an outstanding choice for your avionics needs. Clean, professional installs and located at a very friendly GA airport.

  Thom installed a projector bulb in my Sandel SN 3308 HSI. I described the problem over the phone and Thom got the part ordered and we scheduled the appointment. The repair went great, no surprises! Thom made it easy. The HSI now works and I couldn't be happier. Thanks Thom!

  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.

  Outstanding install of G-5s in L-19 and autopilot repair in Super Viking.

  Thom and Kevin did my Aspen 1000 MAX PFD upgrade - quality work at the price they promised, and worked around their busy schedules to get me in when the winds were better for the cal flight. Cannot recommend highly enough; would give six stars if possible.
From David Greene on 13-Oct-2020

  Five stars!!! I cannot say enough good things about Thom Duncan. He has done much of the work on my Solitaire, both during my ownership, as well as during the years it was owned previous to my purchasing it in 2011, and I have been extremely happy with the quality, workmanship and Professionalism. Most recently, I had a serious issue with my autopilot- it would not engage at all in flight, (but tested fine on the ground checks). Due to my being situated in New England I was unable to get the plane down to Thom this time, but over the course of the last two weeks through multiple phone calls back-and-forth he methodically walked me through a systematic troubleshooting process until we finally found the cause. Thom took the time out of his busy day multiple times for me, even on weekends, to take my calls and patiently help me get to the source of the problem, (all at no charge I might add). I highly recommend Thom Duncan for any avionics related work you might need.
From Gary Bond on 29-Jun-2020

  Thom is professional, experienced, and very focused on getting it right the first time. I had a pretty minor issue with the altimeter on my Aspen PFD but he treated me more than just another customer. Cannot recommend him highly enough.
