How to change HVAC air filters
Most maintenance and repairs should be left to the professionals when it comes to HVAC units. However, most homeowners can easily replace the air filter themselves without any issues. All in all, it should take less than a few minutes to swap out the filter.
Why you need to change the filter
It’s easy to forget about changing the air filters in your home. However, you will feel the consequences of old and dirty filters. They compromise the efficiency of your HVAC systems and negatively impact your health. Typically, air filters need to be changed every three months but check your specific manufacturer’s instructions.
The filter is to trap airborne contaminants such as dust, spores, pet dander, and spores. Over time, the filter becomes clogged with debris. As a result, your home can be dustier, and you may experience allergy-like symptoms or asthma inside. A clean filter can help.
Air filters also play a vital role in the efficiency of your HVAC system. Dirty and clogged air filters restrict airflow throughout your home, forcing your HVAC to work harder with poorer results. Consequently, you will experience uneven heating and cooling with higher energy bills. The strain on your HVAC system can reduce its longevity.
How to change an outside AC unit filter
Turn off the AC unit.
Locate the old filter and remove it from the main unit or air return duct. Otherwise, it could be in your home's access panel, walls, or ceiling.
As you remove the old filter, pay attention to its orientation. You must insert the new air filter in the same way. Furthermore, the new filter must be the same size as the old one. The existing filter should have the size marked on it.
Use a vacuum or damp cloth to clean the part of the AC that houses the filter.
Insert the new filter! If your AC unit has a reusable filter, then wash it thoroughly. It must dry completely before being re-inserted into the AC.
This is also a good time to clear immediate surroundings of any dirt or debris that has accumulated.
How to change a furnace air filter
Turn off the HVAC unit.
Locate the air filter. The location will vary depending on the HVAC model. Look for it behind the main panel, the side, or the bottom of your HVAC unit.
Pull out the old filter. There will be a number printed on it that indicates its dimensions. The new filter must be the same size as the original. Additionally, pay attention to the airflow arrow. This arrow must be pointing into the furnace.
Using the airflow arrow, insert the new filter.
