Unless homeowners have invested in routine HVAC maintenance, the air filter is an often overlooked aspect of AC efficiency and indoor air quality (IAQ). Changing the air filter regularly is important to your health and the health of the HVAC system. The effectiveness of filters in general depends on the type of filter being used. However, new air filters do wonders for system performance and IAQ. The following points outline why HVAC air filters should be higher on your list of priorities.
Importance of HVAC Air Filters
The air filter captures dirt and other contaminants before they get to HVAC system and cause damage. However, it also removes contaminants from the air you breathe, reducing allergies, asthma, and other illnesses.
If you do not change the air filter regularly, it will not be able to effectively trap contaminants. Additionally, a clogged filter impedes air flow through your home, forcing the system to work harder to heat or cool it effectively. This puts undue strain on the HVAC unit, causing damage, and ultimately shortening its life span.
Changing HVAC Air Filters
How often you should change the air filter depends on several factors, including the type of filter you use and activities within your home. It is important to follow the manufacturer’s recommendations specified for your type of filter. You may need to replace it more frequently if:
- There are pets that have a lot of fur
- There are persons who smoke frequently
- Door or windows are opened frequently
- You notice a lot of dust around the house
Turn off the system before replacing the air filter. If there is a lot of dirt on the filter, it is certainly time to replace it. Your HVAC technician will be able to provide advice regarding the best type of filter for your system, and how often it will need to be changed.
