What Goes Wrong When You Have Clogged Air Filters?

Did you know that when air filters are clogged with dirt, dust and other particles, the chance of system breakdown is high? If you have not known it yet, here is a list of dangerous possibilities when your system’s air filters are blocked:

High Energy Bill

Your system’s blower fan is essential for consistent recirculation of your heating and cooling system. With clogged air filters, however, the fan finds it too hard to draw air throughout your home. As it struggles to move air, the higher energy bill is consumed by your system which leads to higher costs. Cleaning air filters can help homeowners decrease their overall energy use by 15 % according to the US Department of Energy.

Frozen Evaporator Coils

One of the most common HVAC issues during summer is a frozen evaporator coil which is typically caused by clogged air filters. When particles hinder proper air flow, there is not enough air flow in the coil to disperse the condensation. If this happens, the condensation collects in the coil and eventually freezes. A frozen evaporator coil prevents your system from removing heat in the air and may cause it to shut down completely.

Uneven Heating and Cooling

Clogged air filters cause too much stress in the blower fan, making it inefficient in doing its job. If the filters are obstructed, the blower fan has to blow harder to let the air pass through. This can cause inadequate heating or cooling inside your home. You will also notice the occurrence of hot and cold spots and find it hard to get the temperature set on your thermostat.

Poor Indoor Air Quality

Dirty air filters contribute to unhealthy indoor air. When you start to use your system, all the dust and dirt that are blocking the filters will be blown back and recirculate in your home. This triggers allergy symptoms and respiratory problems to the people who dwell inside. The situation is even worse if you are living with pets or you are using harmful chemicals in your home.

System Failure

A clogged air filter can cause system failure due to the internal damages it brings. Aside from an overworked blower, obstructed air flow can also lead to major problems in the system.
