Years Serving
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.
We keep the process straightforward and transparent. From your first call through completion, we treat you like a neighbor, not just a customer.
Contact us at (530) 254-6571 or email office@advancedcomfortcontrol.com to describe your heating or cooling issue. We'll find a time that works for you, including emergency calls anytime.
Our NATE-certified technician will inspect your equipment, diagnose the problem, and explain what needs to happen next. We answer your questions and walk through all options.
Once you approve, we perform the work using the latest technology and methods. Our team handles the job thoroughly and keeps your space clean throughout.
We confirm everything runs properly and review maintenance tips with you. You have our contact info for any questions or future service needs.
