Failing to regularly change air filters can lead to reduced air quality and increased energy costs. When filters become clogged with dust, dirt, and other debris, they restrict airflow through the HVAC system. This blockage can cause the system to work harder to circulate air, leading to higher energy consumption and ultimately increasing energy costs.

Additionally, when airflow is compromised, the system may not effectively filter out contaminants, resulting in poorer indoor air quality. Pollutants, allergens, and dust can accumulate in the living space, adversely affecting the health and comfort of occupants. Regularly changing air filters is essential for maintaining optimal airflow, efficiency, and air quality in indoor environments.
