Is Your HVAC System Making Your Allergies Worse?

Understanding the Link Between HVAC Systems and Allergies

If you suffer from allergies, you might think that staying indoors will help reduce exposure to allergens. However, your HVAC (Heating, Ventilation, and Air Conditioning) system could actually be making your symptoms worse by circulating dust, mold, pet dander, and other allergens throughout your home.

How Your HVAC System Can Trigger Allergies

1. Dirty Air Filters

HVAC filters trap dust, pollen, and other airborne particles. If not replaced regularly, these filters become clogged and allow allergens to recirculate in your home.

2. Mold and Mildew Growth

Excess moisture in HVAC ducts creates the perfect environment for mold and mildew growth. Spores from these contaminants can spread through the air, triggering allergic reactions and respiratory issues.

3. Dust and Debris Buildup in Ducts

Over time, dust, pet hair, and other debris accumulate in air ducts. When the HVAC system operates, these particles are blown into your living space, worsening allergy symptoms.

4. Poor Ventilation

An improperly ventilated home can trap allergens inside, reducing fresh air circulation and increasing indoor air pollution levels.

5. Pest Infestations in Ducts

Rodents and insects can find their way into HVAC ducts, leaving behind droppings and dander that contribute to poor indoor air quality.

Solutions to Improve Indoor Air Quality

1. Replace or Upgrade Air Filters

• Use high-efficiency filters with a MERV rating of 13 or higher.
• Change filters every 1-3 months to ensure they effectively trap allergens.

2. Schedule Professional Duct Cleaning

• Hire experts like Nevada Pure Air to remove dust, debris, and mold from your HVAC ducts.
• Regular duct cleaning prevents allergen buildup and improves airflow.

3. Control Indoor Humidity

• Maintain humidity levels between 30-50% using a dehumidifier.
• Prevent mold growth by fixing leaks and ensuring proper ventilation.

4. Install an Air Purifier

• Use a HEPA air purifier to capture airborne allergens and improve indoor air quality.

5. Keep Your HVAC System Well-Maintained

• Schedule annual maintenance to inspect and clean the system.
• Ensure the evaporator coils and condensate drain are free from mold and debris.
