Anderson Heating, Air & Insulation isn't a chain that arrived in Calhoun last year. We've been at 519 Pine Street since John Anderson founded the company in 1978. The technicians who show up at your house went to school here, raised their kids here, and probably have an Anderson sign in their own front yard.
When you call us, you're not getting a call center routing you to whichever subcontractor has open capacity. You're getting the same family business that has done HVAC, insulation, and ductwork for thousands of Calhoun homes — including, very likely, several houses on your street. That's why 640+ of your literal neighbors have left us five-star reviews.
The trust signal you can verify yourself — earned over decades from real Northwest Georgia homeowners.
Calhoun is home for us. Our shop at 519 Pine Street has been the same address for nearly five decades. We've serviced HVAC systems on every street in the Old Town district, every neighborhood off Highway 53, and out toward Dews Pond Road. We know which homes around the Mohawk and Shaw plants are running 1980s ductwork that's leaking 30% of conditioned air into the attic.
Calhoun's mix of older Craftsman homes downtown and newer subdivisions off Hwy 41 and Hwy 156 means we see every kind of HVAC issue. Older Calhoun homes often need duct sealing and insulation before a new system makes sense — the typical 1950s-70s ranch loses 35% of efficiency to envelope leaks. We perform the BPI-certified blower-door test that nobody else in Gordon County offers.
When you call us in Calhoun, the technician who shows up probably lives a few miles from your house. Same crew, same trucks, same family business since John Anderson founded it. That's why we have 640+ Google reviews from your literal neighbors.
