The Role of HVAC in Indoor Air Quality

Depending on the age and status of your HVAC system, it can either help or hinder your indoor air quality. Whenever you have your HVAC system running, which is most of the time in El Paso, all of the air inside your home circulates through your HVAC system. Therefore, anything that is in your air ducts and filters will enter your home, and you’ll inhale it. As such, it’s vital that you have a well-maintained HVAC system if you want high-quality indoor air.

How Your HVAC System Can Improve Indoor Air Quality 

If you want the air inside your home or business to be as clean and pure as possible, here’s how your HVAC system can improve it. 

Ventilation and Circulation 

The main job of your El Paso HVAC system is to circulate the air inside your home or business. As it’s doing this, the system provides ventilation and keeps air constantly moving. During this process, stale air gets sucked into the HVAC system, circulates through your furnace and ducts, and gets conditioned accordingly. This is also the process by which hot and cold air is produced and circulated into your home or business. 


If your HVAC system is too old, small, or lacks maintenance, it won’t do a good job of providing ventilation and circulation. As such, your indoor air quality will be poor due to stagnant, dirty air. 

Proper Filtration

As air is circulating through your furnace and air ducts, it passes through an air filter. The job of this filter is to remove dirt, debris, pollen, and other harmful contaminants from the air before it gets circulated back into your home or business. 

Over time, however, the air filter will block so much debris that it starts to clog and block airflow. When this happens, it will also start releasing contaminants back into your duct system, where it’s then passed into your home or business. To keep this from happening, it’s important to inspect and replace your air filters every one to three months or as needed. 

Humidity Control

The third way that your HVAC system affects air quality is in its ability to remove humidity from the air. When your air conditioner is turned on, its primary job is to supercool the air inside your duct system, where it then gets passed back into your home or business. 

As it’s doing this, your HVAC system also removes the humidity from the air so that it doesn’t feel as damp or moist. When your HVAC system is too small, too large, or inadequately maintained, it won’t be as effective at humidity control.
