Have your indoor air quality tested every 2 to 3 years, or sooner if you’ve had any major changes (renovation, new pets, new diagnosed allergies, water damage, recent HVAC replacement). Homes with chronic allergy, asthma, or respiratory issues should test annually until baseline air quality is established.
Testing frequency
- Most homes — every 2–3 years
- After any renovation or remodel
- Following water damage or mold remediation
- Annually for asthma or allergy-sensitive households
- When buying a new home
See our indoor air quality service for testing and treatment recommendations.
