What is IAQ (Indoor Air Quality)?
IAQ (indoor air quality) describes how clean and healthy the air inside a building is — particulates, allergens, VOCs, humidity, and ventilation all factor in. In HVAC practice it covers filtration, purification, ventilation, and humidity control working as a system.
Why it matters in Arizona
Arizona homes stay sealed tight for six months of cooling, recirculating the same air while fine desert dust infiltrates constantly — a combination most of the country doesn't deal with. The effective order of operations here: seal the ducts, upgrade filtration, then consider purification.
