"Great family business, highly recommend !"

"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."

"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."

"I can’t say enough good things about Thom and his entire team. Excellent communicators, excellent service, excellent work, and an excellent story involving a sensationally folded one dollar bill. This shop will be the first call for my avionics work from here forward."

Thom was very helpful, honest, and thorough. There were no hidden costs and everything was completed very quickly. I can't thank Thom enough for working me in to his busy schedule for a very intricate battery replacement. Even after my visit Thom called to check up and make sure everything was working well. Top quality service. Thanks again Thom.

"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." 

"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."

"Excellent experience with Thom and his crew. We had him do an Aspen PFD install and general panel cleanup in our Piper Cheyenne, it was done with precision and quality."

"Thom and his crew did a fantastic job with my Cherokee with new avionics! It was so pleasant to have someone that was honest and fixed it all correctly the first time. Thom was very transparent on everything and communicated very well! I will always take any aircraft to Thom Duncan!" 

"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. Upgraded to new Aspen! And it is FINE! They know what they're doing. Happy to share my experience with anyone who wants first-hand reporting."

"Thom and his crew are awesome! He got my comms working top notch and helped me with a few burnt out dash panel lights. He was able to squeeze me in and get it done quickly. He also got me the best price on parts and shipping! You won’t go wrong having him and his crew work on your aircraft."

 

"Great avionics upgrade, service, and warranty. Friendly staff and airport facilities. Very comfortable leaving my aircraft with the shop." 

"Highly recommend Thom Duncan Avionics. My first experience was yesterday. He personally replaced and calibrated a TSO's PAI700 compass and calibrated it. He then calibrated my dual Aspen PFD/MFD 1000s for directionality, very accurately according to the GNS 430W GPS."

“The Thom Duncan Avionics team delivered what they said they would do on time and under budget. Thanks again, guys. I highly recommend giving Thom a chance if you’re looking for an avionics shop.”

“Thom is an outstanding technician with incredible customer service skills. Would, gladly, recommend Thom Duncan Avionics to any pilot!”

“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".

"What makes Thom Duncan Avionics stand out in avionics?

Thom and his entire team will take the time to review all of your issues. Then, discuss all of the options.

Before the work on my airplane, Thom must have spent at least two hours on the phone going over my onboard avionics. We discussed software issues and updates. Hardware recalls and warranty coverages. I needed the pitot-static system checked and the ELT battery replaced. I wanted to have the ability to select the flight director display to either single cue or duel cue at the pilot's discretion on my GFC 500. His team also updated some software that required updating.

I Flew in at 7:50 a.m., and the work was all completed by 1 p.m.

Call ahead if you are thinking of using him. His schedule fills up. I highly recommend Thom Duncan Aviation."

"Was having issues with a tail beacon ads-b. THOM and team were able to quickly troubleshoot the issue and work with the manufacturer to get me a replacement. The work was done quickly and the best part was everything they told me they would do was accurate. Additionally, they performed a VFR pitot static check on my airplane. These are great people and I’m so glad I found them."

"Thom Duncan has avionics in his blood. You talk, he listens and responds with what YOU need, NOT what he needs to sell you! A first class, straight shooting, knowledgeable gentleman. 5 star all the way! "

"Thom has helped me out twice now. This is a highly competent shop who also doesn't mind explaining things to us, speaking for myself, dumb pilots."

"Thom offers quality repairs and installs at fair prices. In my experience, he delivers on time as promised."

"The absolute BEST avionics repair and installation shop east of the Mississippi! Thom Duncan and his staff are experts at their craft. From the second I walked into their shop, I felt like part of their family. The technical knowledge and skills that ALL OF THEM possess is the best I have ever seen. DO NOT GO ANYWHERE ELSE for avionics repair or installation."

"You cannot do better than the team at Thom Duncan Avionics. Excellent communication, easy to work with, and they have integrity: The will get it done when they said they would and like their tagline says, they get it right the first time. No one else is touching my bonanza's panel from now on but Thom's shop"

"First class Avionics Service and Install facility. From the Avionics install on my Cessna A185F to diagnosing and repairing our Beech D18S autopilot, outstanding. And, the support and consultation once the job is complete, "the best". I consider them friends!"

"Thom and his team are very neat and organized with all aspects of the job. I’ll definitely use them again!"

"Great avionics shop. Thom commits to a schedule and sticks with it! We’ve used him for small and large projects over the last several years."

"I have worked with Thom to fix multiple avionics issues on my aircraft. He has always worked me into his schedule efficiently. He has spent a significant amount of time over the phone diagnosing the issues prior to my flying over to reduce the number of trips necessary. Definitely planning on continuing to use him for my avionics work.."

"Excellent Work"

"Great Service. "Right the first time"
Highly recommend."

"On time, In budget, Excellent craftsmanship, Tidy, Neat and extremely knowledgeable as to what works best for any mission and any pilot!!"

"Right the first time. You don't see a motto like that unless they mean it. Thom and his team are the definition of right the first time. He kept in touch with me throughout the whole install process, from sending progress photos to asking about where I wanted something located before drilling holes. They took extra care to square up the holes without damaging the panel paint. This made the project go a little longer than planned, but it was well worth it!! Everything fits so nice, it's like it was meant to be. His door is always open if I ever have any questions while I enjoy my new toys. If you are interested in a panel upgrade check him out! Be sure to get on the schedule if you are serious as he can get booked out."

"I called Thom Ducan Avionics to get a price on installing dual G5's in my C210 and to my surprise Thom answered the phone. I shared with him a few of my questions and concerns and he gave me an hour of his time talking about G5's, Gi-275's, my STEC 60, 430 and roll steering. His knowledge and concern for understanding what I was trying to accomplish was off the charts.
I am smarter after talking to him. Thom did not owe me all of that, but he certainly earned my future business because of it.
Thank you Thom."

"I recently relocated to Tennessee. I needed to find a new "Avionics guy". Thom was suggested, and I set up an appointment for warranty replacement of GFC500 servos. Thom completed all the warranty work, updated all of my firmware at my request (some under warranty, some on me, but he saved me a bit by taking the time to check on warranty availability). He also informed me of the new CO detector available for my GTN 750. He showed me the detector and described the process without being overly pushy, just let me know its an option ( I added it). Thom completed all the work ahead of schedule, at a very reasonable price. He exceeded all of my expectations. I think I found my new "Avionics Guy" !!"

"Thom and his guys do a great job! Corrected some issues with the nav system and autopilot. Everything is working perfectly! I highly recommend!"

"I contacted Thom with an auto pilot issue. He took the time to explain everything and some cost upfront. He diagnosed the problem and we got the auto pilot fixed and reinstalled and the it works like a champ. The timeline was what he said it would be or even sooner and did great work. I’ll definitely be a customer in the future."

"Thom is a very precise individual and really focuses on the details so the work goes smooth. They have a great facility. Definitely recommend them for jobs large and small."

"Great working with Thom. Quickly diagnosed the problem. Took care of my plane while waiting for unit to be prepared. All around great experience"

""Diagnosed and fixed an autopilot problem quickly and efficiently. Very knowledgeable and experienced. A pleasure to work with.

"We recently had Thom Duncan Avionics upgrade the STEC autopilot in our Cirrus SR22 to a DFC90, and I couldn't be more pleased with the experience.
From start to finish, Thom and his team were outstanding. Their attention to detail is second to none, and their customer service is better than just about anything I've experienced in recent years. Thom is incredibly easy to work with, communicates exceptionally well, and was always available when we had questions.

Throughout the project, he kept us informed with timely updates and photos, which gave us a lot of confidence that the work was being done right. While the airplane was in the shop, we also had them tackle several smaller items on our maintenance list. Every one of those issues was addressed perfectly and at a very fair price.

It's refreshing to find a shop that combines technical expertise, honest pricing, and excellent communication. Thom Duncan Avionics has earned our trust, and they'll be our first call for any future avionics or aircraft work. Highly recommended."

"Fantastic autopilot work. Shipped my LRUs to them for repair. They came back and worked great, better than it ever worked."

"I own and operate a very busy flight school in Nashville . We desperately needed a carbon copy airplane of our G1000 diamond DA40 because it was flying its tail off and we were one breakdown away from putting several students out of commission.

An exhaustive search produced what seemed like a turnkey airplane for which we paid a premium , except we were grounding the plane every flight or two due to an avionics issue. Our in house A&P tried everything. We were losing about $800/day every day it sat grounded over the course of the first month of ownership. We couldn’t afford to keep throwing good money after bad and needed *the* fix. No more guessing.

We knew that Thom was the guy to call. Communication was excellent. Our A&P described the issue and everything we had tried over the phone, and Thom knew the one thing we hadn’t tried. Gave us a window to bring it in, promised he’d have it fixed and out the door in a week, and they hit the target. When we brought it down, he knew my name and what I was there for.

Picked the plane up and it’s been flying smoothly ever since. Thom himself has followed up with me daily since we got it back. Not just a guy who runs as many planes through the shop to generate invoices. He genuinely wants to solve your problem.

The kind of business owner I try to model my own business after. Thanks guys!!!"

"Thom is an amazing resource in all things Avionics, take the time to meet him and he will take care of all your current and future needs!"

"Thom is great! I had an HSI issue that he was able to quickly diagnose, and then swiftly fix. Their customer service is great, and the work they did was phenomenal. I will be recommending Mr. Duncan to everyone that needs avionics work."

"Thom has unlimited patience on the phone and in person. Great troubleshooting and customer service skills, to say nothing of the avionics talent of his team. Stellar experience in every regard. Highly recommend - thank you, Thom!"

"Wow! I can’t say enough nice things about Thom and Kevin and the whole crew! My Zlin Savage has a new Garmin 205r radio which I love but it’s never had great reception. They fixed me right up…and quickly! They increased the size of my comm antenna ground plane. I was able to receive an ATIS 65 miles out!! It used to be 10-20 if I was lucky. So happy with the service, knowledge and price."

"Excellence, professional service."

"I highly recommend Thom Duncan Avionics. Was thoroughly impressed by not only the diagnosis Thom himself was able to perform but the fact that he wanted the aircraft fixed as bad as I did. He just so happened to have both parts in stock and opted to spend 4 times the allotted time to ensure I left with an aircraft that didn't have to be brought back. "Right the first time" is on their logo and I can see why. A++ business."

"Absolutely the best shop ever."

"Just wish my transponder/altimeter check was more frequent haha Maybe not but I do always enjoy my time at Thom Duncan. A great spot where I can do work while things get done. Highly Recommend"

"I recently took my plane to Thom Duncan Avionics to have two Garmin G5s and a Garmin GFC 500 autopilot installed, and I couldn't be happier with the experience.

Upgrading avionics is a major investment, and finding a shop you can trust with your aircraft is extremely important. Thom Duncan Avionics delivered a great experience, and I'm very pleased with the upgrades.

If you're considering avionics work on your aircraft, I highly recommend giving Thom Duncan Avionics a call!!"
