Why Indoor Air Quality Matters in Fall and Winter

When the Texas summer heat fades and cooler evenings settle in, most of us close our windows and crank up the furnace. It feels cozy, sure—but here’s the catch: with your home sealed tight, the air inside can get up to 5 times more polluted than outdoor air.

That’s why indoor air quality (IAQ) becomes such a big deal in the fall and winter.

What’s Actually in Your Indoor Air?

You don’t have to see it to be breathing it. Common indoor pollutants in Central Texas homes include:

• Dust and pet dander that build up faster once windows are closed
• Mold spores from damp fall weather
• Allergens that sneak in from ragweed and cedar season
• Germs and bacteria that spread more easily when everyone’s indoors together

If you’ve ever noticed headaches, dry throat, or your allergies flaring up in the cooler months, poor indoor air could be the culprit.

How to Improve Indoor Air Quality in Fall & Winter

The good news? A few smart upgrades to your HVAC system can make a huge difference.

1. Media Filters – These high-efficiency filters trap tiny particles your standard filter misses. Think of it as giving your lungs backup.
2. UV Lights & Reme Halo – Installed inside your ductwork, they neutralize bacteria, mold, and viruses before they circulate through your home.
3. Regular Maintenance – A clean, tuned-up furnace means cleaner air and fewer dust particles blowing through your vents.
4. Smart Thermostats – Devices like Ecobee or Nest can monitor air quality and remind you when it’s time for filter changes.
