Where It Started
Raised Behind a Calhoun Grocery Counter
Before there was ever an Anderson truck on the road, there was a neighborhood grocery store in Calhoun, back when folks still saved their Green Stamps. JD and Amanda “Bobby” Anderson ran it, and their kids, John, David, and Susan, grew up behind the counter: bagging groceries, greeting neighbors by name, and learning the look-you-in-the-eye kind of service small towns run on.
When the store’s coolers broke down, JD showed John how to bring them back to life. Something clicked. John wanted to know how things actually worked, and how to make them work right. That curiosity carried him from the store’s coolers into refrigeration, and from refrigeration into heating and air.
John was already serving heating and air customers before John Anderson Service Company, Inc. was formally incorporated in 1978. That date marks the company’s incorporation, with roots in the work he had begun earlier.
The Turning Point
“My New Unit Is In. Why Is My Power Bill Still So High?”
As John installed and repaired heating and cooling equipment, a recurring frustration stood out: a brand-new system could still leave a family with uncomfortable rooms and a painful power bill.
Most contractors would have shrugged and moved to the next job. John didn’t.
“I realized I had to own the whole-house power bill — not just swap the box.”
So he went looking for the real cause. And found it in the house itself: leaky ductwork, thin insulation, and air escaping through gaps nobody was measuring. He learned the building science, became BPI Certified, and built a custom sheet-metal shop on Pine Street so his team could make ductwork that actually fit. Anderson is still a BPI-certified HVAC and insulation company in Gordon County today.
The result: one family-owned company that handles your heating, air, insulation, and whole-home comfort, instead of three contractors who each fix a third of the problem.
Proof, Not Promises
We Don’t Guess What’s Wrong With Your Home. We Measure It.
Anyone can swap a unit. Finding out why your home is uncomfortable or expensive to heat and cool takes testing equipment most HVAC shops have never owned. We test first, show you the numbers, and fix the cause.
-
6
Blower Doors
We measure exactly how much air your home is leaking. Most HVAC shops own zero.
-
6
Duct Blasters
We test your ducts for leaks, so the air you pay to heat and cool actually reaches your rooms.
-
Air-Quality Meters & Leak Detectors
Precision gauges, temperature probes, and indoor-air-quality meters to pinpoint the real problem.
That’s what “building science” means in plain English: test the home, share the numbers, fix the cause, not just the symptom.
Our Promise
If It Can Be Repaired, We Repair It
Here’s an open secret in our industry: telling a homeowner their system is “done” and selling a new one is easier, and more profitable. We don’t work that way. When your system can be repaired, we repair it, and we’re upfront about the price.
That’s how we earn the bigger jobs: by being honest on the small ones. It’s why families in Calhoun, Resaca, Adairsville, Fairmount, and across Gordon County have stayed with us for decades.

Good Work Comes Back Around
When You Hire Anderson, You Help a Neighbor Stay Warm
The same building-science skills we bring to your home go to work for families who couldn’t otherwise afford them. Through weatherization and energy-assistance programs, we insulate and seal homes across Northwest Georgia, keeping those families warmer in winter, cooler in summer, and paying bills they can actually manage.
So choosing Anderson isn’t just buying a repair. It’s backing a local company that puts its skills where they’re needed most.
The People Behind It
A Lasting Friendship. A New Chapter of Leadership.
In 2019, John reached out and asked Shyloh to come to work at the shop. John had long been candid about where his strengths lay: “I can fix anything — I’m just not good at running a business.” Shyloh joined a business with three or four vans running daily and took on the work of organizing and growing its operations.
Under Shyloh’s leadership, the daily operating fleet has grown to nearly a dozen vans. He has led the rebrand and the expansion into Rome and Dalton, building on the technical work and relationships established over the company’s history.
Who Leads Anderson Today
Shyloh Chavez leads the company as General Manager, Vice President and CFO, with responsibility for all daily operations, the team, finances, marketing and business direction.
John has stepped back from daily business management and remains an active member of the Anderson team. Working on his own schedule, he helps troubleshoot technical problems, supports the crew and spends time on shop and personal projects.
You’ll find that same neighbor-first spirit outside of work, too. Shyloh serves on the Calhoun Young Professionals Committee, sings with the Community Chorus, and performs with Calhoun Little Theater, and the whole crew treats every job like a relationship with a neighbor, not a transaction with a stranger.
John & Gypsy

The Shop Pickleball Court
Out in the big lot behind the shop, we painted our own pickleball court: red edges and white kitchen lines, courtesy of a can of Dollar General spray paint. Half the crew plays nearly every day, drivers honk as they pass, and once a year we close for a half-day employee tournament with hamburgers and a trophy. It’s where the Anderson camaraderie lives.
“The Dog Truck”
Our logo is John holding up a finger with his loyal dog Gypsy in his lap. That familiar image became part of the 2023–2024 rebrand led by Shyloh, honoring John’s legacy. The pose started as a happy accident the day our branding came to life, and it stuck because it reflects our down-to-earth, neighborly character. Around town, kids spot the bright purple-and-orange truck and call it “the dog truck.” Gypsy is the mascot behind the Paws-itive Choice.

New Name. Same Family. Same Handshake.
During 2023–2024, Shyloh led the rebrand from John Anderson Service Company to Anderson Heating, Air & Insulation. The name reflects everything we do today, while the image of John and Gypsy honors the company’s roots. Our legal company remains John Anderson Service Company, Inc., formally incorporated in 1978.
In 2026, Shyloh led the opening of our Rome and Dalton offices, expanding from our Calhoun headquarters. Anderson also purchased two electric vans in 2026 to help reduce the fleet’s carbon footprint. Energy efficiency matters in how we run our business as well as in the homes we serve.
