“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!

“Long night flight from Indiana to Florida and lost our beacon lens. Found Horizon and they solved our issue promptly. Nothing in aviation is cheap, but you get what you pay for. Prompt service, clean facility, polite, and caring staff. They had us ready to fly by the time we got back from lunch. Thanks to them, we stayed on schedule for our return home.”
