Indoor Air Quality Guides
27 guidesIndoor air quality covers everything you breathe at home: dust, pollen, pet dander, VOCs, moisture and odors. With cedar season, long cooling months and homes built tighter every year, Austin households have good reason to understand what their HVAC system can and can't do for the air.
Start with How to Improve Indoor Air Quality with Your HVAC System, then learn about filters in What Are MERV Ratings, and How Do They Affect IAQ? and compare options in Air Purification Systems: Choosing the Right One.
For an overview of whole-home air cleaning, filtration and duct cleaning, see our indoor air quality services page.
