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, and furnaces and heat pumps in Marietta put in far more hours than the air conditioner. Count on roughly 64 nights below 32°F and 10 afternoons past 90°F in a typical year. Snowfall averages about 1 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

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 burners light, then shut off a few seconds later
  • Cold air coming out of the vents
  • The thermostat calls for heat and nothing happens
  • The blower won't stop running
  • A yellow or flickering flame instead of a steady blue one

What Moves the Price

  • The furnace's age and brand, which affect parts availability
  • Which part failed: a flame sensor costs far less than a control board or blower motor
  • Night, weekend or holiday rates
  • Whether the part is still under the manufacturer warranty
  • The diagnostic or service call fee

We raised the national figures about 4% 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 safety and combustion check
  • A test run through a full heating cycle
  • A diagnostic check
  • Replacing the part that failed

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

  • Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
  • Have the model and serial number from the furnace label handy. Parts get ordered faster.
  • Ask whether the diagnostic fee comes off the repair bill.
