What causes compressor overheating in a heat pump?

Compressor overheating in a heat pump can be caused by several factors, including insufficient refrigerant levels, which leads to inadequate cooling; mechanical issues such as worn bearings or misalignment; and poor airflow due to dirty filters or blocked ducts. Additionally, high ambient temperatures can exacerbate the problem, pushing the compressor to work harder. Electrical issues, like voltage imbalances or faulty components, can also contribute to overheating. Regular maintenance is essential to prevent these issues.
