Common Questions

Heat pump questions, answered

Clear answers on heating efficiency, winter performance, and practical repair options for Cobb County homeowners.

Modern heat pumps deliver up to 3 to 4 times more heat energy than the electrical energy they consume. In Marietta and Cobb County's moderate winters, heat pumps run in their sweet spot almost all season, keeping heating costs noticeably lower than older electric furnaces or outdated single-stage units.

Efficiency tip

For Georgia winters

Keeping your heat pump filter fresh every 30 to 60 days prevents airflow restriction and protects the reversing valve and compressor from premature failure.
