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.

Our technicians are NATE certified and trained on a wide range of systems, including heat pumps, mini splits, traditional heating and cooling equipment, electrical panels, and Generac generators. We invest in continuing education on a regular basis, so our team stays current as equipment and technology change. That training means we can service and repair most any system we encounter, regardless of brand or age.

We cover a large stretch of northeastern California, including Susanville, Portola, Chester, Greenville, Alturas, Lake Almanor, Graeagle, Janesville, Standish, Milford, Beckworth, Doyle, Westwood, and Taylorsville. Whether you're dealing with a heating failure in the middle of a Sierra winter or an AC system that quit during a summer heat spike, we're close by and available. Our team is on call 24/7 for emergencies, so you're not left waiting when it matters most.

Beyond repairs, we handle full system upgrades and new installations for residential and commercial customers. If your current equipment is aging out or you're ready to move to a more efficient heat pump or mini split system, we'll walk you through your options honestly and help you choose what fits your home, your budget, and your climate.

Integrity isn't a slogan for us. It's the reason we've kept growing since 2006 in a region where word travels fast and your reputation is everything. We hold ourselves to a standard of quality work, fair pricing, and straight answers because that's what we'd want if we were the customer.

If you're ready to find out what Advanced Comfort Control can do for your heating and cooling needs, give us a call or send us an email. We look forward to getting to know you.

What you can count on

Family-Owned Accountability

Bill, Crystal, and their sons run this business and live in the same communities they serve. When your name is on the truck, every job matters.

NATE-Certified Technicians

Our technicians hold NATE certification and complete regular continuing education. That means accurate diagnostics and repairs done right the first time.

Honest, Fair Pricing

We treat every customer like a neighbor, because most of the time they are. You get straight answers and fair pricing, not upsells you don't need.

Wide Service Range

From heat pumps and mini splits to electrical panels and standby generators, we service and repair most system types so you don't need multiple contractors.

Emergency On-Call Coverage

Heating and cooling problems don't follow business hours. Our team is on call around the clock for urgent situations when you need help most.

Ongoing Training Standards

We invest in regular technical training so our team stays current with the latest equipment and methods. That knowledge shows up in the quality of every service call.

I had an excellent experience with Advanced Comfort Control. They came out the same day I called, quickly diagnosed the issue, and completed the repair during the same visit. After the repair, they thoroughly tested the system to make sure everything was working properly before leaving. The technician was professional, polite, and transparent throughout the entire process. He clearly explained what was wrong, what needed to be repaired, and answered all of my questions without any pressure. I really appreciated the honesty and quality of service. I’m extremely happy with the entire experience and would definitely recommend them to anyone needing HVAC service.

Advanced Comfort Control recently repaired my air conditioner, they came out the day after I called them. Which was wonderful, diagnosed and came back in a few days and installed a new fan motor. Very professional and I couldn't be happier with the prompt response and repair. They also worked on my furnace last winter and did a great job then too in a timely manner. Thank you very much to the Harkness family and associates of Advanced Comfort Control, Inc.!!

Had a solar system put in by the team. They did great work, also had a heater installed in our shop. Works fantastic. We also have had repairs to our heater hoses lines, under house and repairs on our heat pumps/ air conditioning units. The guys at Advance Comfort always were on time, helpful, and curious. When needed will call again. Thanks Bill.

These guys were on it within a half hr they were at my place and in another half hr they had my place nice n toasty with heat . They are awesome and good at what they do. Good price house call.. I definitely recommend them.

Debra Barker Google review · March 2026

I have used Advanced Comfort Control for 3 different installations. 2 mini-split systems (one at our home and one at our church, and a home generator system). I rely on them for their honesty, quality and reliability. They are easy to contact in an emergency (I had to get heater working for my dad in middle of winter). They do warranty work when there was an issue with the manufacturer product. Zero problems after 7+ years of service. When you call an hvac company, remember, they will be going through your entire house for the installation, warranty work and maintenance. Get someone you trust.
