Furnace filters are designed to trap airborne contaminants from entering into the air you breathe. Great for air-quality control. But did you know that furnace filters also help in keeping those same airborne contaminants from entering in your heating and cooling systems? If your filter is neglected, physical and financial damages will be inevitable.


Here are some reasons why you should remember to change your filter.


Change your filters every 90 days.


There are different variations of filters that require specific attention for each. It really depends on the thickness of the filter and the air quality of where you live. However, a three months rotation is generally recommended.


What happens if you forget to change your filter?


Disaster can strike your home if due diligence is not played out. Both heating and cooling equipment are sensitive machines. Without proper filtration, dirt and debris will clog the unit chambers and cause worsening performance and damage.


If your filter remains contaminated and clogged, the HVAC equipment will struggle to keep up with its duties.


The dirty filter will cause blockage that results in water damage to the HVAC system and excessive indoor humidity. If the airflow is blocked by debris, the HVAC equipment can overheat, causing increased excess energy consumption, short cycling, total system failure—all of which will make your bank take a tumble.
