5 Signs Your Home Has Poor Indoor Air Quality

Indoor air quality has a real impact on how you feel at home — your sleep, your allergies, even your energy. Here are five signs yours could use some attention.

1. Persistent dust

If surfaces get dusty again almost immediately after cleaning, your ducts may be recirculating it.

2. Musty or stale odors

Lingering smells often point to moisture, mould, or debris in the system.

3. Allergy flare-ups indoors

If symptoms are worse at home than outside, indoor air may be the culprit.

4. Uneven airflow

Rooms that feel stuffy or never quite get comfortable can signal blocked ducts.

5. You can't remember your last cleaning

When in doubt, an inspection is the easiest way to know for sure.
