AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

Atlanta's mixed-humid climate & your HVAC
This Zone 3A (Warm-Humid) climate splits the year between heating and cooling load. Federal SEER2 14.3 (Southeast Region) minimum applies to new AC equipment. A heat pump handles both heating and cooling from one outdoor unit.

Atlanta had an estimated 529,110 residents on July 1, 2025. In Atlanta, the median home was built in 1987 with a current median value of $420,600. Around 46% of homes are owner-occupied. About 40% of households heat with natural gas vs. 58% electric. The Georgia grid averages $0.14/kWh.

HVAC in Atlanta, GA: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Georgia licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Hartsfield-Jackson Atlanta International Airport (KATL) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00013874), Atlanta records an annual mean temperature of 63.6°F, approximately 2,530.9 annual heating degree days against 2,051.0 cooling degree days, 50.43 inches of annual precipitation, and only 2.2 inches of snow. The 1.2:1 HDD-to-CDD ratio makes Atlanta nearly balanced between heating and cooling load — the textbook definition of a dual-need Zone 3A warm-humid climate, where both system halves matter meaningfully.
Atlanta’s 50+ inches of annual rainfall and warm-humid summers make dehumidification as important as raw cooling capacity. Per ENERGY STAR’s right-sized air conditioner fact sheet, oversized units “short-cycle,” and “short operation times do not allow the system to effectively remove humidity”; right-sized units “provide better dehumidification.” For Atlanta homeowners, the practical implication is specifying a system to Manual J load calculations — not the “always bigger” shortcut — and considering variable-capacity equipment that can run at partial load for longer, sustained dehumidification runs.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 House Heating Fuel and B25035 Median Year Structure Built for Atlanta city, Georgia) report 231,504 occupied housing units with a median year built of 1987. Heating-fuel distribution: 58.0% electricity (134,338 units) and 39.6% utility natural gas (91,777 units), with 2,979 bottled/LP-gas homes and 1,502 homes reporting no fuel used. Atlanta’s electric-heat share is notably higher than the U.S. average (40.8%), reflecting the prevalence of heat pumps and electric resistance strip heat in the 1970s–2000s subdivisions that dominate the city’s post-war housing stock.
Georgia Licensing Authority
Georgia requires HVAC contractors to hold a Conditioned Air Contractor License (Class I or Class II) issued by the Georgia Secretary of State’s Construction Industry Licensing Board. The license is the state-level credential every Atlanta HVAC contractor must carry; Class designations reflect permitted scope of work. Verifying a contractor’s active Conditioned Air license before authorizing work is a basic due-diligence step. Permit fees for residential mechanical work in Atlanta are set by the City of Atlanta Office of Buildings (Department of City Planning); contact the Office of Buildings directly for the current fee schedule, as amounts are updated periodically. For an overview of federal and state incentive programs, cross-reference the DSIRE database (N.C. State University / U.S. DOE) or the ENERGY STAR Rebate Finder (EPA).
Georgia Power
Atlanta is served by Georgia Power for electricity and Atlanta Gas Light for natural gas. Per the Georgia Power Home Energy Improvement Program page, current residential HVAC-related rebates (as of September 2026) include: conversion to air-source heat pump — 50% rebate, up to $1,500; conversion to ground-source heat pump — 50% rebate, up to $300; smart/programmable thermostat — 50% rebate, up to $150; duct sealing — 50% rebate, up to $600; HVAC maintenance and tune-up — 50% rebate, up to $75.
