How do airflow restrictions primarily affect heat pumps?

Airflow restrictions primarily lead to inefficiencies and increased energy use in heat pumps. When airflow is restricted, the heat pump has to work harder to circulate air throughout the system. This results in decreased performance, as the unit struggles to maintain the desired indoor temperature. The increased workload causes the system to draw more energy, leading to greater operating costs and lower energy efficiency.

In a heat pump, optimal airflow is essential for effective heat exchange; restricted airflow can disrupt this process, causing the pump to consume more electricity while failing to adequately heat or cool the space. Therefore, understanding the impact of airflow on heat pump efficiency is crucial for ensuring proper operation and energy savings.
