Why Indoor Air Quality Matters During Flu Season in Rowlett, TX

Why Indoor Air Quality Matters During Flu Season in Rowlett, TX

When flu season rolls into North Texas, the quality of the air inside your home matters more than ever. According to the U.S. Environmental Protection Agency (EPA), most people spend nearly 90% of their time indoors—often in spaces where pollutant levels can be higher than outdoor air. For homeowners in Rowlett, Dallas, Rockwall, Wylie, Garland, and Plano, TX, maintaining clean indoor air plays a big role in keeping families healthy and reducing the spread of seasonal illnesses.

Common Sources of Indoor Air Pollutants

Indoor pollutants come from everyday activities and materials. Biological contaminants—like viruses, mold, bacteria, pet dander, dust mites, and pollen—are especially common throughout homes in the Dallas–Fort Worth area. Chemical pollutants such as carbon monoxide, radon, and volatile organic compounds (VOCs) from paints, cleaning supplies, and building materials also linger in the air.

Simple actions like cooking, heating, or even walking across the room can push particles into the air. Without proper ventilation or filtration, these pollutants continue circulating and impacting your indoor air quality.

How Poor Indoor Air Quality Affects Your Health

Breathing polluted indoor air can lead to symptoms such as throat irritation, headaches, dizziness, or fatigue. Long-term exposure may contribute to more serious problems like respiratory diseases or cardiovascular issues.

During flu season—especially when North Texas residents spend more time indoors—poor indoor air quality can worsen flu symptoms and increase vulnerability to viruses. Fine particles irritate the respiratory system and weaken natural defenses, making it easier for illness to spread.

The Benefits of Indoor Air Quality Testing in Rowlett, TX

Professional indoor air quality testing helps identify what’s floating around your home’s air. At StevenSons Heating & Air Conditioning, we test for mold spores, VOCs, dust mites, pet dander, carbon monoxide, and other pollutants. Knowing what’s in your air allows you to take targeted steps toward cleaner, healthier living.

For example, if mold spores are detected, you can act quickly to address moisture issues and reduce allergy or respiratory symptoms.

How HVAC Air Filters Help Keep Your Indoor Air Clean

Your HVAC system’s air filters play a major role in capturing pollutants before they spread. When filters get clogged, they can no longer trap contaminants effectively—and your heating and air system has to work harder, reducing energy efficiency.

Most homes in Rowlett, TX and surrounding areas benefit from changing air filters every one to three months. Factors like pets, allergies, and system usage can affect how often replacements are needed.

Why Air Duct Cleaning and Inspections Matter

Over time, dust, debris, pet hair, and even mold can accumulate inside your air ducts. When your HVAC system runs, these pollutants travel through your home, affecting indoor air and overall comfort.

Duct cleaning is especially important when:

• You notice visible dust or debris around vents
• There are signs of pests in your ductwork
• You smell musty odors when your system runs
• You’ve recently completed remodeling or construction

Regular duct inspections help ensure your HVAC system isn’t circulating contaminants—and can help improve airflow and system performance.

Controlling Indoor Humidity for Healthier Air

In Texas, humidity swings can be dramatic. Ideally, indoor humidity should stay between 30% and 50%. Excess humidity encourages mold and dust mite growth, while overly dry air can irritate nasal passages and make viral transmission easier.

Humidifiers and dehumidifiers help keep your home balanced year-round and prevent common indoor air quality issues.

Air Purifiers: An Extra Layer of Protection

Air purifiers—especially those with HEPA filtration—can remove very fine particles that standard HVAC filters might miss. While they don’t replace proper ventilation or maintenance, purifiers can significantly reduce allergens and airborne contaminants in your Rowlett or Dallas-area home.

The Importance of Proper Ventilation

Introducing fresh outdoor air dilutes indoor pollutants and improves air circulation. Whether you open windows during mild weather, use exhaust fans, or simply adjust your HVAC settings, better airflow helps reduce the spread of flu viruses and enhance indoor comfort.

Simple Habits to Improve Indoor Air Quality

• Avoid smoking indoors
• Use kitchen and bathroom exhaust fans
• Choose low-VOC cleaning products
• Vacuum frequently with a HEPA-filter vacuum
• Change HVAC filters regularly

Flu season is a great reminder that the air inside your home matters. With proper ventilation, clean filters, balanced humidity, and regular HVAC maintenance, your home or business in Rowlett, Dallas, Rockwall, Wylie, Garland, or Plano can enjoy cleaner, healthier air all winter long.
