When the seasons shift, most people focus on staying comfortable by shutting off the AC and turning on the heat. However, that change can also affect your indoor air quality in ways you might not expect.
Your Airflow Is Changing
After months of cooling mode, your HVAC system has been circulating air in a specific pattern. Once you switch to heating, airflow changes. That shift can stir up dust, allergens and buildup inside ducts, especially if the system hasn’t been cleaned recently. It’s also when humidity levels start to fluctuate indoors.
Time for a New Filter?
Filters work hard all summer trapping pollen, dust and debris. When heating season starts, that same filter now handles slower, warmer airflow. If it’s already clogged, it can’t trap particles as effectively, which means more contaminants in the air just as your home closes up for the season.
Humidity Swings Can Throw Things Off
AC naturally reduces moisture, but once heat kicks in, especially from a furnace or heat pump, indoor air can become dry fast. That dryness can lead to irritated sinuses, dry skin and a dustier home. On the flip side, a damp fall can lead to too much moisture, creating a breeding ground for indoor allergens. Balancing humidity is key.
Your Ductwork Might Be Hiding More Than You Think
Over the summer, dust and pet dander often settle inside ductwork. Once heating starts, that debris can blow right back into your living space, triggering allergy symptoms or unpleasant smells. If your ducts haven’t been checked in a while, it might be time.
Signs of Poor Indoor Air
Watch for these common signs during the switchover season:
- Musty or stale odors when the system turns on
- Dust building up more quickly than usual
- Dry or irritated sinuses, eyes or skin
- Increased indoor allergy symptoms
- Uneven humidity or comfort in different rooms
Why Fall Is a Good Time to Reset
Fall is a great time to prep your system and improve air quality. Replacing filters, checking ductwork or installing IAQ solutions can help avoid bigger issues later. A small investment now means a more comfortable and healthier home all season long.

Indoor Air Quality FAQs
What is indoor air quality?
- IAQ refers to the condition of the air inside your home, including allergens, pollutants, moisture levels and airborne particles.
Can poor indoor air affect my health?
- Yes. Poor IAQ can trigger allergies, dry out your skin and sinuses and lead to fatigue or breathing issues.
Do I need to clean my ducts every season?
- Not always, but if you notice musty smells, extra dust or worsening allergy symptoms, it may be time to schedule an inspection.
