Your indoor air quality score is a composite rating based on the factors most likely to affect the air you breathe at home. Unlike expensive professional monitors or lab tests, this quiz uses the same risk factors HVAC professionals look at when deciding whether duct cleaning is warranted.
The score doesn't measure particulate matter or CO2 directly. Instead it weighs the inputs that drive contamination: pet dander load, filter maintenance habits, renovation dust, moisture exposure, home age, and symptoms. It's a reliable first screen before spending money on professional testing or cleaning.
Most homes sit in an acceptable range. But certain conditions push air quality into territory that affects health and comfort:
1. Upgrade your HVAC filter
Switch to a MERV 11-13 filter and set a calendar reminder to change it every 60-90 days. This single change has the highest impact on indoor particulate levels.
2. Get a professional duct inspection
A camera inspection ($75-150) shows exactly what's in your ductwork. For homes that score high on this quiz, it removes guesswork and helps you decide whether full cleaning is warranted.
3. Address moisture sources
Check your condensate drain line and drain pan annually. A clogged condensate line is the most common cause of mold in residential ductwork and is inexpensive to clear.
4. Schedule duct cleaning when justified
The EPA recommends cleaning only when there's visible mold, pest infestation, or significant debris buildup. For homes with pets, renovations, or years of neglected maintenance, those conditions are often met.
