Anderson Heating, Air & Insulation (formerly John Anderson Service Company, est. January 1978) — BPI Certified experts in HVAC, insulation, weatherization & whole-home energy solutions across Northwest Georgia.
"Many customers see significant energy savings after combining HVAC upgrades with insulation, air sealing, and duct improvements. Some pay less with financing than they did on their old power bill alone."
— Results vary by home, system condition, usage, and utility rates
Founder John Anderson with the next generation of Anderson leadership and Gypsy — the real-life Paws-itive Choice.
John Anderson founded the company in Calhoun in January 1978. The technician who shows up at your house probably grew up in Gordon County, raised kids here, and has an Anderson sign in their own front yard.
That's different from the big Atlanta HVAC chains pushing into Northwest Georgia. Those companies send a rotating cast of subcontractors and route after-hours calls to corporate dispatch two states away. We answer our own phone. Same crew. Same trucks. Year after year.
It's why 632+ of your neighbors have left us 5-star reviews — and why we've been the #1 HVAC company in Calhoun Magazine for 6+ consecutive years.
Most local HVAC companies advertise "24/7 emergency service" and route after-hours calls to a voicemail no one checks until Monday morning. We do this differently — and we're up front about how it works.
Our 24/7 line is staffed day and night, including weekends and holidays. Live answering on every call. Most competitors send you straight to voicemail after hours — we don't.
If we installed or serviced your system recently and it's failing — we roll a truck, weekday or weekend, day or night. True emergencies (no heat in freezing temps, gas concerns, water damage, vulnerable family) are evaluated by our on-call tech and dispatched when conditions allow.
For repairs that can wait, we take your information and follow up first thing the next business day. Our regular business hours are Monday–Friday, 7:30am–5:00pm. We'd rather get you on the schedule than guess at a window we can't make.
We'd rather tell you the truth and beat the call window than over-promise and miss. That's the Anderson way — same approach we've taken since 1978.
When we diagnose a problem, we'll walk you through what's wrong, what your repair choices are, and exactly what each one costs — before any work begins. You decide what fits your home and your budget. We deliver exactly what you paid for, backed by warranty.
You choose. We deliver. We stand behind our work.
