Will a new air conditioner help with indoor air quality?

Yes, a new air conditioner can significantly improve indoor air quality through two main functions:

1. Filtration: All ACs have air filters that trap airborne particles like dust, pollen, pet dander, and mold spores. A new system often comes with a clean filter, and you can choose filters with higher MERV (Minimum Efficiency Reporting Value) ratings (e.g., MERV 8-13) for better filtration of smaller particles, including some bacteria and viruses. Regular filter replacement is crucial for this benefit. Subscribe for our Annual Maintenance Reminder that makes life easier for you!
2. Humidity Control: Air conditioners remove excess moisture from the air as they cool. High indoor humidity creates an ideal environment for mold and mildew growth, which can release spores and VOCs (Volatile Organic Compounds) that negatively impact air quality and health. By maintaining optimal humidity levels (typically 30-50%), your new AC helps inhibit this growth.

Some advanced systems also offer features like UV lamps to kill mold and bacteria on coils, or specialized air purification add-ons for enhanced cleaning.
