Spring is just around the corner. Unfortunately, so are seasonal allergies. If you’re one of the millions of allergy sufferers in the U.S., warmer weather can mean uncontrollable sneezing, coughing, watery eyes, and difficulty breathing. But did you know that you can reduce your allergy symptoms and improve your home’s air quality with regular HVAC maintenance? Read our blog for 5 HVAC tips to reduce seasonal allergies.

5 HVAC tips to reduce seasonal allergies.

Use high quality furnace filters

Furnace filters are the first line of defense against indoor air pollutants such as pet dander, dust mites, and pollen. Over time, filters become clogged and dirty, which constricts airflow and allows allergens to circulate freely throughout the home. Consider upgrading your furnace filter to a high-qualtiy HEPA (high-efficiency particulate air) filter, which removes at least 99.8 percent of contaminants in the air. Changing the filter every three months (or sooner if you have pets or an older HVAC system) can significantly reduce the amount of allergens in your home and help alleviate symptoms.

Clean registers and vents regularly

Heat registers and air vents circulate air from your HVAC system. If they’re neglected, dust, dirt, and other particles will blow and settle throughout the interior of your home. Consider cleaning your registers and vents at least once a week with a damp or treated cloth before you dust the rest of the house. This will prevent contaminants from returning after you’re finished cleaning. If you have wood floors in your home, you may need to clean two to three times a week. In addition, it’s a good idea to have your ductwork cleaned by a professional every three to five years.

Check for mold and mildew

It’s a fact. Mold and mildew thrive in dark and damp places. A neglected or improperly maintained HVAC system that collects condensation or humidity may lead to the growth of unwanted contaminants. This could exacerbate allergies, asthma, and other illnesses. Schedule a routine maintenance appointment with your HVAC professional to inspect your system and ensure the ductwork is clean. Also, if high humidity is an issue, consider having your technician install a UV light near the system’s evaporator. This will absorb heat drawn into the home, as well as kill bacteria and other harmful microorganisms that aggravate allergies and asthma.

Clean your outdoor unit

Although your HVAC system filters air before it enters your home, you still should consider having your air conditioning unit cleaned on a regular basis. When the consender coil gets dirty, the air conditioner works harder to blow cool air. As a result, the unit performs at a less than optimal level and does a poor job of dehumidifying the air inside. Warm, moist air can worsen allergies as well as cause unwanted bacteria growth. Contact an HVAC professional to have your unit serviced annually.

Regular HVAC maintenance

The best and most cost-effective way to prevent allergens from invading your home is to keep your HVAC system maintained and operating properly. Be sure to schedule regular maintenance by a heating and cooling professional, including ductwork cleaning, to improve air quality and keep the system running efficiently. And, as mentioned earlier, change the air filter at least every 90 days or sooner.
