A heat pump repair in Cobb County starts with a question a contractor has to answer before they can price the job: what wore this component out? 105 severe weather events were recorded in Cobb County, Georgia between 2015 and 2024. At that rate, severe weather is a standing feature of what every system here runs against, and it shows up in the equipment. Capacitors, contactors, and refrigerant lines all absorb that load over the years. A contractor who skips that assessment and replaces a part without tracing the cause is likely to see the same failure again.

Ductwork and wiring installed when many of these houses were new have been carrying heat pump loads through revision after revision, and what a technician finds inside a unit here often reflects that layered history. Half the homes in Cobb County, Georgia were built in 1990 or earlier (2020-2024 ACS 5-year). By the time a heat pump in stock this old needs a repair call, the capacitors, contactors, and refrigerant lines have typically been working hard for a long time, and what the opened system contains drives the scope of the job far more than the initial symptom does. A coil showing corrosion, a contactor worn past its rating, or a refrigerant circuit that has lost charge slowly over years each points to a different repair and a different parts list.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. These are the pieces a contractor reaches first when something goes wrong. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each stop the system in its own way.
Inside the house, the air handler hangs in a closet, attic, or utility space and moves conditioned air across its own coil. The reversing valve, which lives in the outdoor unit, tells the system which direction to run. The expansion valve and refrigerant lines that connect both units are also on a contractor's checklist when the outdoor and indoor symptoms do not point to one obvious part.
The drawing shows a representative layout, and a licensed contractor determines which components apply to your specific house and system.

Outdoor conditions put cumulative stress on heat pump components, and that stress compounds over time. Repair needs in Cobb County track closely with what the local climate actually demands of the equipment.
