The HVAC air filter plays a major role in keeping your energy bills low, ensuring better indoor air quality (IAQ) and lengthening the life of your cooling and heating systems. When the filter is covered with dust, the airflow slows through the air handler. It may create any of these problems throughout your system:
- Dust inside the air handler. When filter is covered with dust, the air handler pulls it inside and it can cover internal components. Should the blower motor get covered with dust, it will run hotter, which shortens its life. The airborne particulates also can cover the evaporator coil through which the refrigerant flows.
