The presence of airborne particles can cause clogging of the evaporator coil, reducing its ability to effectively absorb heat. This can lead to decreased cooling efficiency and higher energy consumption. Additionally, when dust and debris accumulate on the fan blades, it can disrupt the airflow, causing strain on the motor and potentially leading to motor failure.

It’s important to note that some airborne particulates can also trigger allergies or respiratory problems, making it imperative to maintain good indoor air quality. Without an air filter, these particles can circulate throughout the house, exacerbating allergies and potentially causing health issues.

Reduced Efficiency From Contamination In The Air

One of the primary functions of an air conditioner is to improve indoor air quality by removing contaminants and maintaining a comfortable environment. However, running an AC system without a filter hampers its ability to perform this function effectively.

Contaminants present in the air, such as:

  • dust
  • allergens
  • mold spores
  • bacteria

can freely enter and circulate throughout the AC system. This can compromise the efficiency of the system, as these contaminants can settle on critical components like the evaporator coil. When the coil becomes dirty, it becomes less efficient at absorbing heat, resulting in reduced cooling capacity and increased energy consumption.

Lack Of Protection Leads To Long-Term Damage

Operating an air conditioner without an air filter leaves the system vulnerable to long-term damage.

The absence of a filter allows dirt, debris, and contaminants to settle on key components of the AC system, including the blower motor and condenser coil.

Over time, accumulated dirt and debris can obstruct airflow, leading to reduced performance and efficiency.

Additionally, if particles settle on the condenser coil, it can hamper the system’s ability to release heat, causing the AC unit to work harder and potentially leading to component failure.
