The Importance of Replacing Air Filters

Dec 12, 2014


Why is it Important to Change my Filters in a Timely Basis? 

A homeowner is advised to change their HVAC filters on a regular basis in order to keep the air in the home clean. This should be done regularly in order to decrease the chances of pollutants and allergies from entering the home.

The best thing about changing a filter is that it is an easy task and very inexpensive to achieve. Here is more information on changing the filters for the heating and cooling system:

Effects Of Not Changing HVAC Filters

Most homes use a heating pump or furnace in order to provide ventilation in the home. This includes the heating and air-conditioning system. Each of the filters have their own screen used to prevent dangerous particles from clogging up the system. When the filters are not regularly changed, dust and soot can enter the system and damage the machinery.

The system may also experience a pressure drop which can lead to a reduction of air that blows out of the system into the home. This adds a lot of strain on the machine, causing it to malfunction or work incorrectly.

This can cost the homeowner thousands of dollars in repairs or for a replacement. Dirty filters may also become damp and produce mold. Mold can lead to serious long-term health damage, such as cancer, lung disease and respiratory infections.

Some units come with a pre-fixed label that will show the consumer how to replace the unit. It is always recommended to hire a professional to take care of repairs and replacements.

How Often Should a Filter To Be Changed?

Filters should be changed at least once a year. Most HVAC and furnace units contain many moving parts, which is why it is important to make sure there are no cracks in the belts. Other issues that can occur due to not regularly changing the filter include; ventilation ductwork damage, clogs in the fan and coils and much more.

Homeowners should run their units six months out of the year. Filters should be changed once a month if there are pets in the home or if there are a large amount of occupants in one residency.

If there are smokers in the home, fireplace, large garden, construction taking place, or an occupant with a respiratory condition, it essential to change the filter at least once a month. If the filter is damaged, damp, or has mold spores on the filter, it should be changed immediately.
