If you don't change your AC filter regularly, several problems can arise:
Reduced airflow: A dirty or clogged filter restricts airflow, making it harder for your AC system to push air through the ducts. This can lead to reduced cooling efficiency and uneven cooling throughout your space.
Decreased energy efficiency: Restricted airflow caused by a dirty filter forces your AC system to work harder to maintain the desired temperature. This results in increased energy consumption, higher utility bills, and unnecessary wear and tear on the system.
Poor indoor air quality: The primary function of the AC filter is to capture dust, pollen, pet dander, and other airborne particles. A dirty filter loses its effectiveness in trapping these pollutants, leading to poor indoor air quality and potential respiratory issues.
System malfunctions and breakdowns: If a filter becomes excessively dirty and clogged, it can cause strain on the AC system. This can lead to overheating, freezing of the evaporator coil, or even system shutdowns and breakdowns.
To avoid these issues, it's essential to regularly change your AC filter according to the manufacturer's recommendations. This ensures proper airflow, improves energy efficiency, and promotes better indoor air quality.
