In Fulton County we handle AC repair, furnace service and heat pump work across the south half of Georgia's most populous county, where houses range from historic districts built before 1946 to much newer streets. Older homes usually need duct and airflow fixes alongside the repair, while airport-area homes need equipment matched to a tighter shell. We answer the phone 24/7.
Old Campbell County ground and the cities on it
Fulton is Georgia's most populous county, with 1,066,710 residents in 2020, and it absorbed Campbell and Milton counties at the start of 1932. Most of our Fulton work sits on that old Campbell side. Fairburn was Campbell's county seat from 1871 until the merger, and today it is one of several south Fulton cities with very different housing from street to street.
College Park keeps a 606-acre National Register district whose 853 historic resources were mostly built between 1882 and 1946. The city of South Fulton did not exist until 2017, yet it counted 107,436 residents in 2020. Further south, Union City grew from a 1908 incorporation to 11,414 housing units, and Palmetto lies mostly in Fulton with a section in Coweta.
Inside Atlanta's limits we also work the southwest neighborhoods. Cascade Heights, annexed in 1953, has large homes on hilly lots under the city's second densest tree canopy. Shade helps summer loads there, but leaf litter and pollen collect in outdoor coils.
Airport-side homes that were sealed for noise
Hartsfield-Jackson's Noise Insulation Program treats eligible homes built before April 10, 1985 inside the 65 dB DNL contour, including homes in East Point and Hapeville. Treatments can include new windows and doors, air conditioning modifications and exhaust fans.
A house sealed that way keeps its windows closed most of the year, so the AC does more of the comfort work. If a replacement is sized off the old tonnage instead of the tighter shell, it cools fast, shuts off early and leaves the rooms damp. We size from a load calculation of the house as it stands now.
Forty-four hot days, forty freezing nights
Atlanta now averages about 44 days a year at 90F or hotter, up from 37 under the older normals. Long runs like that are where weak run capacitors, worn contactors and dirty condenser coils finally quit. January turns the load around with a high near 52F, a low near 34F and roughly 40 freezing nights, enough to find a cracked hot surface ignitor or a heat pump that never finishes defrost.
When a repair bill on an older Fulton system starts to look like replacement money, the federal floor matters. Since January 1, 2023, new split-system central AC installed in Georgia must meet 14.3 SEER2 below 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h or above, judged by installation date. We lay out both paths so you can compare them on paper.
Heating and cooling work that fits Fulton County
AC Repair
Long 90-degree stretches across south Fulton push capacitors, contactors and fan motors past their limits.
Furnace Repair
Roughly 40 freezing nights a year is when idle ignitors, flame sensors and inducer motors show their wear.
AC Replacement & Installation
Homes sealed under the airport noise program need replacement equipment sized for the tighter shell, not the old tonnage.
Duct Repair & Sealing
College Park's pre-1946 houses had ducts added long after construction, often with leaky joints in attics and crawl spaces.
Whole-Home Dehumidifiers
Closed-up airport-area homes can hold indoor moisture when the AC short cycles.
Heat Pump Repair
January cold snaps test defrost controls and backup heat on Fulton heat pumps.
Fulton County heating and air questions
Because the houses change. A Queen Anne in College Park's historic district usually has retrofitted ducts that limit airflow, an airport-area home may have been sealed for noise and needs smaller equipment than before, and a newer South Fulton house tends to need refrigerant, drainage or control repairs instead of layout changes.
Eligible homes built before April 10, 1985 inside Hartsfield-Jackson's 65 dB DNL contour, in places such as College Park, East Point, Hapeville and parts of Atlanta. Treatments can include windows, doors, AC modifications and exhaust fans. If your home was treated, tell us when you call so we account for it.
You can keep repairing it. The 2023 SEER2 minimums apply to new equipment by installation date, not to fixing a system already in place. The rule only comes into play when you choose a replacement, which then has to meet 14.3 SEER2 below 45,000 Btu/h.
Parts that sat idle all summer: hot surface ignitors that crack on the first start, flame sensors coated with residue, and pressure switches or inducer motors that struggle with a partly blocked vent. With about 40 freezing nights a year, a fall check catches most of them before a cold night does.
Often, yes. Houses built before central heat had ducts added later, so returns are small and runs are long. We check static pressure and duct condition before blaming the furnace, because a healthy furnace on choked ducts still heats unevenly and can overheat.
