Intro

Changing the air filter is one of the most important things homeowners can do.

What This Means

The air filter keeps dust out of the system. When it is dirty, airflow drops.

Common Problems from Dirty Filters

• Poor cooling

• High energy bills

• Frozen AC

• System shutdown

Safe Things a Homeowner Can Do

• Replace filter every 1–3 months

• Use correct filter size

• Make sure airflow arrow points the right way

If airflow is still weak, call a professional.
