5 HVAC Tips to Reduce Winter Allergy Symptoms

Replacing the air filters every two to three months ensures they effectively capture any dust or allergens that can trigger symptoms. Additionally, people with severe allergies should replace their old air filters with upgraded HEPA models. These are specifically designed to capture ultra-fine particles, including dust, dander, and pollen, so they provide more protection against allergies than traditional filters.

When the system runs, the condenser pulls air from outside and circulates it throughout the home. That means it's also drawing in any allergens that are surrounding the unit. Ensure there isn't any debris leaning on the equipment and clear out vegetation in a two-foot radius surrounding the system. You can also have the fins cleaned to remove any contaminants that have gotten lodged in them.

Any allergens that aren't captured by the filters end up in the system's ductwork. When heated air moves through the ducts, those contaminants circulate throughout the home, diminish the indoor air quality, and make symptoms more likely. Have them professionally cleaned in the fall months and regularly dust the registers throughout the home to ensure the allergens don't trigger symptoms.

Even if temperatures are mild, keep the fan turned on to help reduce allergic reactions. If the system is off, the air stays stagnant and traps allergens in the home. Keeping it running forces the contaminants through the system so they're captured by the HEPA filters or directed outside, which bolsters the air quality.

Whole-house air purifiers provide the best protection against winter allergies. They're particularly effective because they clean the air at the source rather than in individual rooms to provide broader protection. Whether this device uses electrostatic filters, electronic filters, or UV filters, it'll remove a host of irritants, including dust mites, mold spores, pollen, and pet dander.
