The Holiday Season and the Air We Breathe

As we transition into the cooler months in Charleston, our windows stay shut longer, the A/C flips to heat, and families spend more time indoors preparing for gatherings, holidays, and cozy nights. But while you’re focused on turkey recipes and guest lists, there’s something else lingering in your home that deserves attention: your indoor air quality (IAQ).

In this guide, we’ll walk you through what IAQ really means, why it’s especially important during the holiday season, and how Charleston-area homeowners can protect their families, guests, and homes from the hidden pollutants floating indoors.

What Is Indoor Air Quality (IAQ)?

Indoor Air Quality refers to the condition of the air inside a building — in this case, your home. It considers everything from humidity levels to airborne contaminants like:

  • Dust and pet dander
  • Mold spores
  • Pollen and outdoor allergens
  • Volatile Organic Compounds (VOCs) from cleaning products or scented candles
  • Carbon monoxide
  • Tobacco smoke or fireplace emissions

These elements build up even more as we seal our homes from the chilly fall and winter air.

Why IAQ Gets Worse in Fall and Winter

The very act of staying warm can reduce your indoor air quality. Here’s how:

  • Reduced ventilation: Closed windows mean less fresh air circulation
  • Heat mode = dust mode: Kicking on the heat stirs up dormant dust in ducts and vents
  • More time indoors: Family, pets, and guests all contribute to airborne particles
  • Holiday products: Scented candles, cooking fumes, and fireplace smoke contribute to VOCs

What the EPA Says About IAQ

According to the Environmental Protection Agency (EPA), Americans spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations. In some cases, indoor air has been found to be up to 100 times more polluted than outdoor air.

Why is this a problem? Because poor IAQ has been directly linked to:

  • Increased asthma and allergy symptoms
  • Cold-like illnesses and respiratory infections
  • Headaches and fatigue
  • Long-term lung and cardiovascular health concerns

How IAQ Affects Charleston Homeowners

Charleston and Lowcountry homes face unique IAQ challenges:

  • High humidity encourages mold and mildew
  • Older homes may have outdated or dirty ductwork
  • Pollen and outdoor allergens linger longer in the region
  • Hurricane season can leave behind water damage or electrical issues

Many homeowners are unaware that their HVAC system, especially if unmaintained, can contribute to poor indoor air quality.

Signs Your IAQ May Need Attention

  • You notice dust build-up quickly after cleaning
  • You or your family frequently sneeze or experience congestion indoors
  • There’s a musty or stale smell in your home
  • Guests have allergy flare-ups when visiting
  • You haven’t had your system inspected in over a year

How to Test and Improve Your IAQ

Testing Options

  • Hire a licensed HVAC professional to evaluate your IAQ during a system check-up
  • Use at-home IAQ monitors for humidity, VOCs, and carbon monoxide
  • Check your filters monthly for excessive build-up or discoloration

Improvement Solutions

  • Upgrade air filters to high-efficiency pleated, electrostatic, or HEPA filters
  • Install UV lights to kill mold, bacteria, and viruses in your air handler
  • Clean your ducts professionally to remove years of build-up
  • Add a whole-home air purifier for advanced allergen and odor removal
  • Install a dehumidifier to keep humidity between 30–50 percent
