HVAC Tips

Why February Is the Worst Month for Indoor Air Quality

By February, most Bel Air homes have been sealed up for months. Windows stay closed, heaters cycle regularly, and fresh air circulation is limited. While this helps keep homes warm, it also allows indoor air pollutants to build up—often unnoticed.

Many homeowners assume poor air quality is only a spring allergy issue, but February is when indoor air is often at its worst.

What Causes Poor Indoor Air Quality in Winter

Stale, Trapped Air:
With limited ventilation, airborne particles linger longer inside the home.

Dust and Dander Buildup:
Pets spend more time indoors during winter, increasing allergens in the air.

Humidity Imbalances:
Dry winter air can irritate sinuses and skin, while excess moisture can encourage mold growth.

Overworked Filters:
HVAC filters collect more debris during winter months and may become clogged if not replaced regularly.

Signs Your Home’s Air Quality Needs Attention

Persistent Dryness or Irritation:
Dry throats, itchy eyes, or frequent nose irritation can signal poor air balance.

Lingering Odors:
Cooking smells or musty odors that don’t dissipate quickly point to inadequate air circulation.

Increased Allergy Symptoms Indoors:
Sneezing or congestion that improves when leaving the house is a common red flag.

Excess Dust on Surfaces:
If dust returns quickly after cleaning, it may be circulating through your system.

How February Is the Ideal Time to Improve Indoor Air

February offers a window to address indoor air issues before spring allergens arrive. Solutions may include:

  • Upgrading air filtration systems
  • Installing air purifiers
  • Adjusting humidity levels
  • Evaluating ventilation performance

Improving indoor air quality now helps create a healthier home environment year-round.

Local Insight

Bel Air homes range from newer builds to older properties with tighter winter seals. While energy efficiency is beneficial, it can also reduce natural airflow. Understanding how local home designs impact ventilation is key to improving indoor comfort.
