It’s a beautiful time of year, but also one that can see allergy symptoms spike as the weather changes. Sneezing, coughing, congestion and itchy eyes aren’t a given, especially if you can harness your HVAC system intelligently. Here are some tried and true methods for ensuring you enjoy a comfortable, allergy-free autumn: 

1. Change your air filter regularly. A dirty air filter can trap allergens and pollutants in your home, which can worsen your allergy symptoms. Change your air filter every 1-3 months, or more often if you have pets or live in a dusty environment. An automatic reminder from ENASTAT based on your systems’ runtime is one way to make sure you don’t forget this crucial safeguard. 
2. Seal any air leaks. Cracks or gaps around windows and doors can let in allergens from outside. Use a sealant or, if the issue is significant enough, consider replacing doors and windows. 
3. Clean your ductwork. If your ducts are dirty, they can trap allergens and pollutants. Have your ducts cleaned by a professional every two to three  years to help keep your home allergy-free.
4. Use an air purifier. An air purifier can remove allergens from the air in your home. This is a good option if you have severe allergies or if you work in an area with high levels of allergens.Options exist both for single-room purification systems as well as whole-building options. 
5. Cycle your fan. As temperatures moderate, you may be inclined to turn off the HVAC system. Leaving the fans running, however, can prevent the air from stagnating and becoming an irritant. 

In addition to these tips, there are a few non-HVAC things you can do to help prevent fall allergies:

• Stay indoors on dry, windy days. Pollen counts are typically higher on these days, so avoiding exposure = avoiding possible symptoms.
• Take a shower after being outdoors. This will help to rinse away any allergens that may have gotten on your skin or hair.
• Change your clothes after being outdoors. This will help to remove any allergens that may have gotten on your clothes.
• Use a saline nasal spray. A saline nasal spray can help to clear your nasal passages and reduce allergy symptoms.
• See an allergist. If your allergies are severe, you may need to see an allergist for treatment. An allergist can help you identify your allergens and develop a treatment plan.

By following these tips, you can help to prevent fall allergies and keep your building comfortable and allergy-free for occupants. Happy heating!
