What is the impact of dirty filters on HVAC system efficiency?

Improves overall efficiency
Has no effect
Decreases efficiency
Increases overall air flow

The correct answer is: Decreases efficiency

Dirty filters have a significant impact on HVAC system efficiency by decreasing that efficiency. When filters become clogged with dust, pollen, and other airborne particles, they obstruct the normal airflow through the system. This restriction forces the HVAC system to work harder to pull air through the filter, which can lead to increased energy consumption and potentially higher utility bills. Additionally, the strain on the system can lead to premature wear and tear on various components, including the blower motor and other mechanical parts. As a result, a system with dirty filters not only operates less efficiently but may also require more frequent repairs and maintenance. Therefore, maintaining clean filters is vital for optimizing HVAC performance, ensuring better indoor air quality, and extending the equipment's lifespan.
