Indoor Air Quality in Phoenix, AZ

Why is there so much dust in my Phoenix home?

Phoenix sits in a designated PM-10 nonattainment area, so outdoor particulate levels here are high by federal standards. That dust enters through doors, through building leaks, and through unsealed ductwork in the attic. Filtration catches some of it, and the rest recirculates if the filter is undersized or overdue. Sealing the ducts usually makes a larger difference than any single product.

How often should I change my air filter in Phoenix?

More often than the package suggests. Valley dust loads filters faster than the national averages those intervals are based on. Checking monthly during the cooling season is a good habit, and replacing the filter when it looks loaded is better than following a calendar. Leaving a filter in too long restricts airflow and hurts comfort and equipment life.

Does duct cleaning actually help?

It helps when the ducts are actually dirty, and the system is otherwise sound. Cleaning removes accumulated debris that would otherwise recirculate. It does not fix leaks, crushed runs, or a dirty coil, so cleaning alone rarely solves a persistent problem. We inspect first and tell you which of those is driving your complaint.

What does a UV light do in an air conditioning system?

A UV lamp installed at the coil limits microbial growth on the wet surfaces inside the air handler. Those surfaces stay damp through the cooling season and are a common source of musty odors. A UV lamp targets that specific problem. It does not replace filtration, and it does not remove dust.

Will better filtration hurt my airflow?

It can, if you choose a filter without regard for the system. A denser filter catches more particulate but also creates more resistance. Systems not designed for that resistance lose airflow and can ice the coil. We match filter rating to the equipment rather than defaulting to the highest number available.

Do you handle indoor air quality for commercial spaces?

Yes. We hold an Arizona CR-39 license, which covers commercial and residential air conditioning and refrigeration work. Offices and suites carry the same dust and duct problems as houses, usually across larger systems. We inspect and quote commercial air quality work the same way.
