The Atlanta market
The City of Atlanta Office of Buildings lists replacing a water heater as plumbing permit work. For existing one- and two-family homes, its exempt list includes repair or replacement of existing air conditioner condensers, but only repair of existing furnaces, so a full furnace replacement is unclear and worth a call. Heat pumps are not addressed. A Georgia-licensed plumbing contractor or the legal owner (signing a homeowner affidavit) may apply, and an adult must be home to let the inspector in. The trade permit form lists $40 per heating system and $40 per cooling system up to 5 tons, plus a $150 minimum base fee whose application to single-family homes is not confirmed. Cooling dominates: EIA counts central air in 86% of Georgia homes and heat pumps as main heat in 27%. Sandy Springs, Roswell, DeKalb and Cobb run separate permit offices.
In Atlanta the air conditioner works much longer each year than the furnace, so it is often the first system to give out. Condenser swaps are routine here, which makes quotes easy to compare on equipment and warranty terms. Ask whether the indoor coil is being replaced to match the new outdoor unit, since a mismatched pair can fall short of its rated efficiency. Ask whether the line set will be flushed or replaced. Get the tonnage, SEER2 rating and model numbers in writing.
