  • Gary

    Gary Mertz


    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!

    Shelley started her working life in the Hospitality Industry (that’s where she and Gary met almost 32 years ago!). In addition to staying home to raise their kids, Shelley worked as a first-grade teacher and started a baking business called Eat Cake, as well as keeping the books for their other businesses, Harvest Moon Energy and Summer Sun Heat & AC. She started in the HVAC business full time when they purchased the Aire Serv franchise in 2016. In her spare time Shelley likes to read, bake, watch football, travel and enjoy time with friends. Of course, her favorite time is spent hanging out with Gary and their kids, Clay and Zoe.
