If you don't change your air filter regularly, it can lead to several issues:
Reduced Airflow: A clogged filter restricts airflow, making your system work harder.
Increased Energy Bills: The extra effort required by your system increases energy consumption, leading to higher bills.
Poor Air Quality: Dust, allergens, and pollutants circulate in your home, worsening indoor air quality.
System Strain: Over time, the strain can cause components to wear out faster, potentially leading to costly repairs or even system failure.
