What symptoms might indicate a dirty filter in an HVAC system?

A dirty filter in an HVAC system restricts airflow, which can lead to reduced system efficiency. When the airflow is compromised, the system has to work harder to maintain the desired temperature, resulting in higher energy consumption. This increase in effort typically translates to higher energy bills for the homeowner. Additionally, reduced airflow can cause inconsistent temperature control throughout the space, creating further issues with comfort.

Monitoring these symptoms is crucial for maintaining an efficient HVAC system. A proper routine of filter maintenance helps ensure that airflow remains unrestricted, minimizing energy costs and optimizing performance. Therefore, noticing reduced airflow alongside higher energy bills is a strong indication that the filter may need cleaning or replacement.
