Allergies and Your Air Conditioner

Spring and summer are prime candidates for allergens outdoors.  Grass, tree, and flower pollen is a concern for seasonal allergy sufferers.  Your HVAC system can help prevent allergic reactions while inside your home. We’ve put together the top tips for preventing allergies with your HVAC system.


1. Change the Filter

Your filter does a lot of work for your HVAC system.  It should be changed regularly, from monthly to yearly, the type of filter impacts the schedule.  However, if you are prone to allergies, you may find you need to be on a more rapid schedule.  Changing the filter keeps your system in top condition, but also the filter catches particles like pollen.  The filter is the best defense for stopping the pollen from circulating in your home.

2. Leave the fan “ON”

The fan on your unit can be set to “auto” or “on.”  Setting the fan to “ON” sends the air through the filter more often which will allow it to better filter allergens from your home.  It will also keep the house more comfortable.  Setting the thermostat to fan on will allow the air in the home to constantly circulate.  This is good for creating a consistent temperature throughout the home, but also allows allergens and debris to constantly move toward the filter to be removed from your environment.

3. Leave Windows/Doors Closed

It can be tempting to open windows on a cool evening to enjoy “fresh” air.  However, this allows allergens such as pollen to enter the home.  These allergens can lead to an uncomfortable night of sleep as your body reacts to the allergens you’ve allowed in the home.
