What could be the result of neglecting the cleaning of air filters in a gas furnace?

Neglecting the cleaning of air filters in a gas furnace can lead to decreased air quality. When the air filters are dirty or clogged, they obstruct the airflow, which makes it harder for the furnace to circulate air effectively throughout the home. This restriction not only reduces the furnace’s efficiency in heating the space but also causes dust, allergens, and other contaminants to accumulate in the air, which can negatively impact indoor air quality.

Additionally, when air filters are not regularly cleaned or replaced, the system can become overloaded, leading to increased wear and tear on components. This can contribute to other problems such as overheating, increased energy consumption, and potentially shorter equipment lifespan. However, the primary immediate concern is the decline in air quality due to contaminants being circulated in the air, which can affect the health and comfort of the occupants.
