Fall Allergies in Virginia: How Your HVAC System Can Help

As temperatures cool down in Portsmouth and across Virginia, fall brings relief from the summer heat—but for allergy sufferers, a whole new set of challenges begins. Ragweed, mold spores, and dust can all flare up in the fall, especially as we spend more time indoors.

The good news? Your HVAC system can be your secret weapon against seasonal allergies—if it’s properly maintained and equipped.

Here’s how to make sure your system helps, not hurts, your air quality this fall:

• Install a high-efficiency air filter.
  Upgrade to a MERV 11 or higher filter to trap smaller particles like pollen, dust mites, and pet dander.

• Schedule duct cleaning.
  Dust and allergens can build up in your ductwork over time. A professional cleaning removes those irritants and helps air flow more freely.

• Add an air purifier or UV light system.
  Whole-home purification systems work with your HVAC to neutralize allergens, bacteria, and even viruses.

• Maintain proper humidity levels.
  Fall often brings fluctuating humidity. A whole-home humidifier or dehumidifier can help keep moisture levels in the allergy-safe zone (30–50%).

• Keep your system maintained.
  A clean, well-running system is less likely to circulate allergens. Fall is the perfect time for a tune-up to ensure filters, coils, and components are in top shape.
