According to a report by the Asthma and Allergy Foundation of America, more than 25 million people in the US live with asthma. The most common type is allergic asthma. With that in mind, improving the quality of air in your home is an important consideration. When the air quality in your home is good, it can reduce common symptoms like shortness of breath, red eyes, and wheezing.

Allergens in your home like pollen, pest droppings, dust mites, and pet dander often aggravate asthma symptoms. HVAC systems are built to filter these allergens but if the system is not optimized, it could do more harm than good. 

Here are four basic but effective ways to allergy-proof your HVAC system:

Schedule annual maintenance

Schedule a visit with a licensed professional every year to ensure your HVAC system is running clean and efficient. Ensure the service call includes replacing air filters and cleaning ductwork.

Clean or replace your HVAC filters

A typical HVAC filter should be deep cleaned every two to three months. A HEPA (high-efficiency particulate air) filter does not need to be cleaned as often, upgrade to save some maintenance time. Generally, a filter must get rid of at least 99.97% of the contaminants in the air to acquire a HEPA rating. If you choose a HEPA filter, select one with a MERV rating of at least 10. MERV ratings grade the quality of the air filtration on a scale from 1 (lowest) to 20 (highest). The higher the score, then the more satisfying the quality of the air. 

Run your HVAC system regularly

Run your HVAC system for at least 30 minutes each day to help with air circulation. The air conditioner moves air in your home by bringing in the fresh outdoor air. If you own a smart thermostat, consider programming your system to run at a specific time and duration.

Install a UV light near your HVAC evaporator

An HVAC contractor can help you install a UV light close to your system’s evaporator. A UV light can control mold growth and other bio-organisms that might be present in your HVAC unit.

For more effective ways on how to allergy-proof your HVAC system, contact a professional HVAC contractor. Let your professional real estate agent know if you've optimized your HVAC system for allergen control.
