The first step in troubleshooting a heat pump system is often to clean or check the air filter. A dirty or clogged air filter can significantly impact system performance by restricting airflow, which can lead to issues such as reduced heating or cooling efficiency, increased energy consumption, and the potential for the system to malfunction. Ensuring that the air filter is clean helps to establish a baseline for the heat pump's operation and can sometimes resolve issues without further investigation. This maintenance task is typically straightforward and should be done regularly as part of routine system upkeep.

While inspecting the outdoor unit for debris, checking electrical connections, and measuring refrigerant pressure are all crucial parts of troubleshooting a heat pump, they generally follow the initial step of addressing the air filter. Cleaning or replacing the filter can eliminate airflow issues and clarify if further diagnosis is needed.
