About Us
air condition repairsOur company has been working under the name HVAC Specialist LLC., since March 1, 2003. We were formerly Gary Service Co. that was owned by our Dad, Gary Gaddy. He started the business in 1977 with both his sons, Doug and David, riding along in service trucks with him at a very young age. Later, both of the sons became employed with Gary's while still in high school. They both worked by there Dad's side for over 25 years. In 2003, due to Gary's health he went on disability causing us to change the name. With over 40 plus years of experience together, we hope that you will still put your trust in us. After all, we learned from the very best...our Dad.
