From one man's realization that "most companies just swap the box" to a 48-year legacy of fixing whole homes — alongside the most loyal four-legged co-founder in Northwest Georgia.
In 1978, John Anderson started what would become Anderson Heating, Air & Insulation in Calhoun, Georgia. Like most HVAC technicians at the time, he focused on installing and repairing heating and cooling equipment.
But something didn't add up. Customers kept calling with the same problem: "My new unit is installed, but my power bill is still sky high."
"I realized I had to own the whole house power bill — not just swap the box."
— John Anderson, Founder
That moment changed everything. John began studying how insulation, air sealing, and the entire home envelope affected HVAC performance. He became BPI Certified. He invested in a custom sheet metal shop with custom sheet metal equipment right at 519 Pine Street so his team could fabricate perfect ductwork instead of forcing round pegs into square holes.
Today, 48 years later, Anderson Heating, Air & Insulation (formerly John Anderson Service Company) is the only company in Northwest Georgia that truly does it all — HVAC, insulation, weatherization, duct cleaning, IAQ, and in-house custom fabrication — under one family-owned roof.
John Anderson founded the company in 1978 and built the standard Anderson is known for — technical excellence and customer trust. Today, Shyloh leads day-to-day operations, marketing, and the back end of the business — including the recent rebrand to Anderson Heating, Air & Insulation, this website, and the systems that get John's standard to every customer. Together they represent both the founding generation and the next chapter of Anderson Heating, Air & Insulation.
Shyloh is active in the Calhoun Young Professionals Committee, sings with the Community Chorus, performs with Calhoun Little Theater, and square dances with the Cherokee Promenaders. That community-first spirit shapes how Anderson treats every job — as a relationship with a neighbor, not a transaction with a stranger.
John, our leadership team, Gypsy and our dedicated support team — the people who make every home comfortable in Northwest Georgia.
