Which maintenance task is critical for maintaining heat pump efficiency?

Regular cleaning or replacement of air filters is crucial for maintaining heat pump efficiency. Air filters play a vital role in ensuring that the heat pump operates at optimal performance levels. When filters are clogged with dust, dirt, and debris, they restrict airflow, making the heat pump work harder to circulate air throughout the space. This increased strain leads to reduced efficiency, higher energy consumption, and potentially increased wear and tear on the system.

Maintaining clean filters not only enhances efficiency but also improves indoor air quality by trapping airborne particles. It's recommended to check and replace or clean the filters regularly—typically every one to three months, depending on usage and environmental conditions. This simple maintenance task can significantly extend the life of the heat pump and keep it running effectively.
