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.
When It Makes Sense
- Energy bills are higher than you want them to be
- The house heats with electric baseboard, oil or propane
- There's no natural gas service on your street
What Moves the Price
- Electrical panel capacity and wiring
- Variable-speed (inverter) or single-stage compressor
- A ducted system or a ductless mini-split
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Size in tons, and whether the unit is cold-climate rated
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

Georgia Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Marietta; the contractor normally pulls it. Before you sign, ask each bidder for their Georgia license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.

Heat Pump Installation Questions from Marietta Homeowners
How much is heat pump installation in Marietta?
Plan on $5,700 to $14,000, with most jobs near $10,300. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Marietta?
Between late spring and early fall. Marietta averages 64 freezing nights a year, and heating calls spike from November through February.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
