What effect does a dirty air filter have on an air conditioning system?

A dirty air filter significantly restricts airflow within an air conditioning system. When the filter is clogged with dust, dirt, and other particles, it cannot effectively pass air through. This restriction leads to several issues, including reduced cooling efficiency, because the system has to work harder to draw air through the obstructed filter. As a result, it can lead to increased energy consumption, as the system operates for longer periods to achieve the desired cooling effect. Furthermore, this added strain on the system can cause wear and tear, potentially leading to mechanical failures and higher maintenance costs. Therefore, maintaining clean air filters is vital for the efficiency and longevity of an air conditioning system.
