What can happen if there is a blockage in the A/C system?

A blockage in the A/C system can lead to high-pressure levels due to the insufficient flow of refrigerant or airflow throughout the system. When a blockage occurs, the refrigerant cannot circulate properly, causing pressure to build up in the system components such as the compressor, evaporator, or condenser. This elevated pressure can result in the A/C system becoming less efficient and may lead to mechanical failures or even compressor damage if the pressure exceeds safe operating levels.

The other outcomes listed do not accurately reflect the consequences of a blockage. Rather than energy savings, a blockage typically reduces the system's efficiency, leading to increased energy consumption. Similarly, a blockage does not enhance cooling effectiveness; it usually hampers the cooling process. Lastly, a blockage will hinder, not promote, proper airflow, leading to reduced performance or uneven cooling in the space served by the A/C system.
