Question: 1 / 400

What happens if an HVAC system's air filter is dirty?

It increases energy efficiency

It improves indoor air quality

It restricts airflow, leading to inefficiency and possible damage

When an HVAC system's air filter is dirty, it significantly restricts airflow. This restriction can lead to several issues. First, when the airflow is reduced, the system must work harder to maintain the desired temperature in the space. This overexertion can cause the system to consume more energy, ultimately leading to increased utility bills and reduced energy efficiency.

Additionally, restricted airflow can lead to imbalanced pressure within the system, potentially causing the compressor or fans to overheat. This may result in mechanical failure or a decrease in the system's overall lifespan. Furthermore, poor airflow affects the distribution of conditioned air, which can lead to uneven temperatures throughout the space.

Thus, recognizing the importance of maintaining a clean air filter is crucial not only for ensuring efficiency but also for preventing potential damage to the HVAC system.
