    Gary Mertz

    CEO

    Gary started in the HVAC Industry over 12 years ago, following more than 20 years in construction and the Hospitality Industry. He has been happily married to his wife, Shelley, for almost 27 years and they have lived in the Flower Mound/Double Oak area for 16 of those. Gary is a huge baseball fan – not easy to maintain when you root for the Mets! In his free time, he loves to cook, read, workout at Every Level Fitness Highland Village and hang out with friends and family. He’s also teaching himself to play guitar. He says his favorite thing about owning Aire Serv of Flower Mound is the chance to meet so many home and business owners in the area and improve the enjoyment level of their home and office surroundings!
