How does HVAC affect indoor air quality?

HVAC systems play a major role in indoor air quality. Properly maintained HVAC systems can help reduce airborne pollutants, such as dust, pollen, and mold, by filtering and circulating air. Additionally, HVAC systems can help maintain a comfortable temperature and humidity level, which can help reduce the growth of mold and mildew. Furthermore, HVAC systems can be equipped with air purifiers to help reduce the presence of allergens, smoke, and other pollutants. By regularly changing air filters and scheduling regular maintenance, HVAC systems can help improve indoor air quality and provide a healthier environment for occupants.
