Air Filter Problems And Their Effect On Air Conditioner Performance

Tammy Terry

Air filters play an important role in keeping air conditioner parts dirt-free. Since they trap dirt and mold particles, they also purify air, something that goes a long way towards improving air quality in a home. However, when they develop problems, they become a liability. The following are some of the most common air conditioner filter problems that have a negative effect on air conditioner performance.

Clogged filters

With time, air filters get clogged with dirt and debris. When this happens, the ability of the filters to let in air into the system is reduced. By restricting airflow into the system, these clogged filters increase the risks of evaporator coil icing. Why? Because an adequate flow of warm air over the evaporator coil is what usually keeps it from freezing. By restricting airflow, clogged air filters cause temperatures in this area to drop below freezing point. This then causes any moisture in air flowing over the coils to not only condense, but also freeze.

The formation of ice layers over evaporator coils insulates the coils. This then reduces the effectiveness with which the refrigerant absorbs heat from air passing over the coils. It therefore reduces the performance of air conditioners.

Torn filters

When an air filter wears out, it develops tears. These tears then allow dirt and debris to get into the air conditioning system. This reduces the ability of the air conditioner to serve as an effective air purification system. Air filters that allow dirt particles and debris into the system also have a negative effect on other parts of the air conditioner. For example, they increase the rate at which dirt accumulates on the fan blades. This in turn reduces the volume of air that the blower unit can suck into or out of the system thereby reducing the overall performance of the air conditioning system.

The dirt and debris that torn filters allow into the system can also settle on the evaporator coil. These then form an insulation layer that comes between the liquid refrigerant and the warm air passing over the coils. As a result, the amount of heat that the refrigerant absorbs at any given time reduces. To achieve a given temperature, the air conditioner will then have to work harder and for a longer period. This reduces the efficiency with which the system uses energy, something that will then increase the energy bills that you will have to bear.

Cleaning a clogged filter with a piece of clothing and soap is usually enough to restore its performance. As for torn filters, you will need to replace them.

Ask your technician, someone from a place Pristine Air Conditioning Corp, what the best option to keep your filters working for your HVAC system is as they install your AC.

About Me
Talking About Air Filtration Systems

Hey everyone, I am Mort Nicholas. Since I have allergies to pollen, dust and chemicals, I must filter the air blowing through my home day and night. The air filtration systems hook straight to the furnace and air conditioner to provide my home with fresh air at all times. The filters used for these systems capture the tiniest of particles to keep them out of my airways. As a result, I often wake up feeling healthy and refreshed. I hope to share the benefits of having filtered air flowing through your home. I will discuss symptoms caused by contaminated air. In addition, I will share information about air filtration maintenance services provided by HVAC contractors.
