Needed to get a pitot-static, altimeter & transponder inspection ASAP. Alex arranged for one of his technicians to meet me on a Sunday. On the flight to Knoxville, I was having some CHT issues. Alex couldn't get a mechanic out on a Sunday, on short notice, but I was first on the list for Monday morning. Sandra, the technician who conducted my inspection, kindly gave me a ride to a nearby hotel. It's a busy shop, but they took care of me quickly. read more

I've been using Horizon Avionics for over twenty years with five different aircraft types. During this time I have taken them some very complicated, seemingly unsolvable issues. Some of these involved issues I inherited with recently acquired airplanes. Issues unsolvable by previous owners. One of these was an experimental airplane with a very sophisticated avionics package that basically didn't work, and for which there was no wiring diagram. They have the technical expertise and experience to diagnose really tough issues. In the over twenty years I have been their customer, I don't believe I have ever been overcharged, and they stand behind their work. I feel comfortable doing business with, and taking advice from Horizon Avionics. read more

So I took my Cirrus SR22 to these guys in July. Dealt with Alex Foulds dodging calls, emails, text etc. Finally sent someone to go get my plane and he stated it was shaking on the way back. We get it to Florida and start looking around and realize half the stuff on their $11,000 invoice was never even done. He wanted $1800 for a full detail job, said he was only going to charge $750 because he could get to the wings. I think what he meant to say was I couldn't do any of it but I'm still gonna charge you something. This is just the start. There were little doors under the wings that were corroded but never mentioned in the $4000 Annual and Inspection I paid for that missed this, broken motor mounts, floating gauges, cracked broken dash, holes on the ailerons that had coverings missing to prevent rodents from getting in etc. These guys threatened to keep my plane unless I paid because they knew once I got it I would realize they did practically nothing. I even asked for corroded screws on dash face to be replaced and Alex told me they got that done and I kid you not the plane arrives and its the same corroded screws still in it. I can say this as I am the one who personally dealt with them. I wouldn't let them work on a go-cart much less a several hundred thousand dollar or even multi million dollar airplane of mine ever again. They refuse to give my my money back as the did nothing correctly or at all on the invoice besides easy stuff they felt like messing with such as a oil change, or battery change etc. I have given them ample opportunity to refund my money so I can pay someone to finish the work and they are just ignoring so I guess at this point they are leaving me no choice but to sue them. I have already received feedback from 3 different companies all verifying they did not do the work the said they did and will be subpoenaed to court if litigation occurs. If they think it will be for just the $11,000 they better thing again. Lots of logistical cost, legal fees, etc that are already involved and about to be incurred from this. You would think they would man up and would realize when there are before and after pictures showing work not done, multiple companies saying they ripped me off and the fact that they are now getting public statements posted about the incident they would just refund the money and part ways but no they won't even respond so as a previous customer speaking with previous experience BEWARE!!!! This was my experience that can be proven with pictures and written statements as will be done in court if a refund is not issues before we file suit. read more

Jonathan was a delight to work with from my very first phone call asking questions to me picking up my airplane with work completed...knowledgeable and polite with a can-do, we'll get it done attitude. I had them move some radios around, remove the intercom, install a new GTX-345 (ADS-B in & out) and GMA-35c. On time and he stuck to his quoted price. My airplane had a small avionics anomaly that was only noticed after I took off in the airplane with work complete and paid for. Jonathan was very accommodating in arranging for me to return my airplane to him and he bought my lunch to boot! Many hours of labor and three days later, I again picked up my airplane and was not charged a nickel for the warranty work, everything worked flawlessly and I grinned all the way home! I will most certainly be a repeat customer for Horizon Avionics! Well done Jonathan!! read more

Jonathan Foulds installed a new Garmin GTX 345 in my T210 in June 2018. Included in the cost of the install was an upgrade to the serial RS 232 encoder. Two weeks ago (8/2018) the transponder began broadcasting inaccurate altitudes. Taking the aircraft to a local shop we discovered that the original 9 grey code wiring had a bad connection. There was no RS 232 wiring installed. Horizon failed to do the work they quoted, nor did they complete the work they claimed was required for the transponder installation. I believe Foulds is dishonest. Steer clear of Horrible Horizon Avionics. Don't trust your aircraft with Foulds or his team. read more

Had two G5's installed and ADSB in/out transponder. Took a little bit longer than expected but the wiring behind the panel looks very neat and tidy. The tech. Took the time to walk me through the install and the features of both my new transponder and the G5's. Very pleased with my experience read more

They installed an ADS-b transponder for me. Competitive quote, quick turnaround time. 6 months later, everything still works as advertised. read more

They made my airplane ADSB compliant, and I'm very happy with my Garmin products!

Worst Place Ever, Owner is a cheat and a Liar, he will tell you one thing and turn around and say I didn't say that. Tells you, you have to Comply with unnecessary work. Took my plane somewhere else and they fixed the Problem for $75.00 read more
