What can be a consequence of not replacing air filters as recommended?

Not replacing air filters as recommended can lead to decreased system performance and air quality. When air filters become clogged with dust, dirt, and other contaminants, they restrict airflow through the HVAC system. This reduced airflow can cause the system to work harder to maintain the desired temperature, which in turn increases energy consumption and ultimately leads to higher utility bills.

Additionally, as the filter becomes more saturated with particles, it is no longer effective at capturing allergens and pollutants, allowing them to circulate in the indoor air. This can significantly degrade indoor air quality, leading to health issues, especially for individuals with respiratory conditions or allergies. Therefore, regular replacement of air filters is crucial for maintaining the efficiency of the HVAC system and ensuring a healthy living environment.
