Our Story Neighbors serving neighbors,
Our Full Story
Neighbors serving neighbors,
since 2006
Advanced Comfort Control, Inc. started in 2006 when Bill Harkness set out to build something the region genuinely needed: a local HVAC company with real skills, honest pricing, and a long-term stake in the community. Bill wasn't coming in from outside. He lives here, works here, and knew that doing right by customers meant doing right by neighbors.
Over the years, the business grew into a true family operation. Today, Advanced Comfort Control is owned and run by Bill, Crystal, and their three sons, Colby, Orrin, and Destry. That family structure shapes how we work. When we show up at your door, we're not just completing a job ticket. We're taking care of someone we're likely to run into at the hardware store or the gas station next week.
