"Most companies just swap the box. We fix the whole house."
— The Anderson Difference
An oversized AC short-cycles, won't dehumidify, and burns out compressors years early. An undersized one runs nonstop and never catches up. Either way, you pay for it on your power bill and in repairs.
Before we quote a replacement system, we perform a Manual J residential load calculation — the ACCA industry-standard sizing method that accounts for your home's insulation, windows, orientation, duct losses, infiltration, and Georgia's actual climate data. Not a square-footage rule of thumb. Not a "your old system was a 3-ton, so the new one is a 3-ton" shortcut. The real math.
It takes us longer up front. It saves you money for the next 15-20 years. That's the Anderson Difference on every install.
We don't just fix your HVAC. We test your insulation, air sealing, and ductwork to make sure your system performs at its best.

Every Anderson replacement install starts with a Manual J residential load calculation — the ACCA industry-standard sizing method. We measure your home, account for insulation levels, window orientation, duct losses, and air infiltration, then run the numbers against Georgia climate data. We do not size by square footage or by matching your old unit's tonnage. Wrong-sized systems short-cycle, don't dehumidify, and fail early — getting this right is one of the most important things we do.
