How Does An AC Filter Work?

The AC filter is made up of fiberglass material and is usually situated near the furnace or return air duct. The filter acts as the barrier to prevent debris and dust from entering the AC system and the air. The AC filter mainly serves two functions:

  • To prevent air contaminants: AC filters prevent air pollutants from entering the AC unit. If dirt penetrates the unit, the cooling functioning of the system is hampered. This calls for AC Replacement Katy TX.
  • To maintain purified air: As air passes through the ductwork and filtration cooling tubes, the dispensed air is purified. The air filters are designed to maintain the quality of the indoor air.

Adverse Effects Of Running AC Without A Filter

Poor Indoor Air Quality

A lack of an AC filter triggers the accumulation of dust and debris in the AC system. These air contaminants get circulated throughout the home, negatively impacting your family members.

Compressor or Motor Issues

Compressor and motor malfunctions are caused by trapped dirt, dust, or debris in the AC unit. The absence of an AC filter will not restrict the air contaminants’ entry into the system. This will strain your system’s efficiency.

Higher Electricity Bills

The compressor or motor issues will make the AC unit work harder to generate cool air into the rooms. This will consume more energy leading to an increase in electricity bills.

Frozen Evaporator Coils

Frozen evaporator coils will generate less conditioned air in the rooms due to trapped air contaminants in the system. It also causes dirty ductwork, thereby restricting airflow.

Is It Necessary to Change AC Filters?

Yes, it is necessary to change the AC filters routinely. This ensures high-quality indoor air. Routine checkups of the AC filters will decrease the chances of frequent AC repairs or replacements.


Hence, it is essential to install an AC unit with a filter. This will prevent your AC system from premature damage.
