True or False: Accumulation of dirt on condensers can lead to reduced efficiency.

Accumulation of dirt on condensers does lead to reduced efficiency, making the statement true. When dirt and debris build up on the condenser coils, they restrict airflow and act as an insulating layer that prevents effective heat exchange. This results in the system having to work harder to remove heat from the refrigerant, ultimately leading to increased energy consumption, higher operational costs, and potential overheating issues. Maintaining clean condensers allows for optimal airflow and efficient heat transfer, which is crucial for the overall effectiveness of the HVAC system. Regular maintenance and cleaning are essential practices to ensure that condensers operate at peak performance, highlighting the importance of keeping them free from dirt accumulation.
