A home's HVAC system can significantly impact air quality, both positively and negatively.

Positive impact

• Filters: When working properly, HVAC filters can trap dust, pollen, and other allergens. 

• Fresh air: HVAC systems can circulate fresh air from outside. 

• Humidity control: HVAC systems can help control humidity levels. 

  
  

Negative impact

• Poorly maintained filters: Dirty or clogged filters can contribute to indoor air pollution. 

• Poor ventilation: Poorly ventilated systems can lead to a buildup of harmful gases like carbon monoxide. 

• Mold and bacteria: Poorly maintained systems can foster the growth of mold and bacteria. 

• Inadequate maintenance: If not properly maintained, HVAC systems can contribute to poor air quality. 

  
  

How to improve air quality

• Change your HVAC filters regularly, especially during allergy season or when it's very hot or cold. 

• Have your HVAC system professionally tuned up and maintained. 

• Consider using HEPA filters, which are the most effective type of air filter for fine particulate matter.
