Marietta price range against the U.S. range, with the climate and housing numbers behind it.

Marietta Weather and HVAC Load

In a normal year, Marietta racks up 3,050 heating and 1,309 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. Count on roughly 64 nights below 32°F and 10 afternoons past 90°F in a typical year. Snowfall averages about 1 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

Marietta Housing Stock

The median Marietta home dates to 1986, according to the Census ACS. That makes the typical house about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 47.2% of occupied homes, roughly 12,000 households. The median home value is $401,100, and median household income is $70,086. We use both figures to adjust labor and pricing for this page.

Cobb County had 9 hail days and 27 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Cobb County also had 3 tornado days in that period.

Symptoms Worth a Service Call

  • The outdoor unit hums, but the fan doesn't spin
  • The AC runs, but the air coming out is warm
  • The system cycles on and off every few minutes
  • Water pooling around the indoor unit
  • The breaker trips when the AC kicks on

What Moves the Price

  • Whether the equipment sits in a tight attic or on a roof
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Refrigerant type and how many pounds it takes
  • Nights, weekends and holidays
  • The service call or diagnostic fee

We kept the national figures close to unchanged for Marietta using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • A test run
  • Replacing the failed part
  • Diagnosis and electrical testing
  • Checking refrigerant pressures
  • Clearing the drain line if it's clogged

Georgia Licensing and Efficiency Rules

Georgia is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Georgia license or registration number before the visit.

Before You Hire

  • Swap the air filter and check the breaker before you call anyone.
  • Ask for the per-pound refrigerant price before any work starts.
  • If you see ice, shut the system off. Running it frozen can kill the compressor.
