What is one common troubleshooting technique for low airflow in a heat pump system?

Inspecting filters and ductwork is a common troubleshooting technique for low airflow in a heat pump system because blockages or dirty filters can significantly hinder the system's performance. Filters that are clogged with dust and debris restrict airflow, leading to reduced efficiency and effectiveness in heating or cooling. Similarly, issues within the ductwork, such as leaks, blockages, or improper design, can also lead to low airflow, as conditioned air may not reach the intended spaces effectively.

By ensuring that filters are clean and ductwork is free of obstructions, technicians can often resolve airflow issues and improve the system's overall function. This proactive measure addresses the most typical causes of airflow problems and helps maintain optimal operation of the heat pump.
