Air Filter Mistakes

September 3, 2020 | Blog

Air filters clean the air that circulates through your AC system by trapping contaminants like dust, dirt and bacteria. However, if there’s something wrong with the air filter, your AC will start to experience problems as a result. To keep your air conditioner in tip-top shape, watch out for these common mistakes the next time you replace your AC filter.

Putting the air filter in backwards

All air filters have one side that is more porous than the other. The porous side allows the filter to trap airborne particles without restricting airflow through your AC. If you put the filter in backwards, air will have a harder time getting into your AC and the unit will be forced to work more to make up for the lack of airflow.

This simple mistake can lead to higher energy bills and an inefficient AC system. To avoid this, always look for the printed arrows on the side of the filter to show you the correct way to install it.

Using the incorrect air filter size

Installing a filter that is too small is almost like not using a filter at all. A small filter leaves gaps around the air vent, allowing harmful air particles to pass through your AC.

Every HVAC filter has its dimensions printed on its side. So the next time you change your filter, make sure you’re replacing it with one that matches the previous filter’s size.

Forgetting to replace dirty filters

Dirty air filters can affect your health and the health of your HVAC system. Clogged filters prevent filtered air from entering the vents. When this happens, your HVAC system’s blower fans have to work harder to circulate air. This will eventually cause your entire system to shut down and could lead to costly repair bills.

To avoid unclean air, unnecessary strain on your HVAC system and higher utility bills, always remember to change out your HVAC filters before they turn grey. Most filters need to be replaced every one to two months. However, if you use higher-efficiency filters, they can last up to three months.
