Cool air is a relief on a hot summer day, but there are some air conditioner parts that may trigger allergies. Usually air conditioners help allergy sufferers. They seal the home, keeping outdoor allergens outdoors. However, not all allergens are found outdoors - many are found, and grow, in the home. Air conditioners do nothing for the dust and other allergens that are already in your home. Dust, for example, is mostly composed of human skin. Unless you were to seal the home and not allow anyone inside, you could not prevent dust from accumulating. Dust mites feed on this skin and are the cause of most allergies. The following guide will help you better understand which air condituoner parts are related to allergies.
Filter
The filter on your air conditioning unit needs to be cleaned regularly. The collected dust can be sent back into the house, circulating until it finds the perfect victim. When the air conditioner is off, the filters may get wet. This moisture makes the dust an ideal place for mold to grow. Once the mold matures, it secretes small spores that are spread throughout the house by the fan. It is possible to purchase a hepa filter for your unit. This filter is hypoallergenic and will help remove dust from the air, but it still needs to be replaced regularly.

Evaporation Tray
Another place that allergens gather is the evaporation tray. The tray is located on the inside the condenser, underneath the evaporation coils. It is not easily visible, but this doesn’t prevent it from getting dirty. It needs to be cleaned and dried on a regular basis. Consistently wet conditions will give rise to mold. Most molds are irritants, but some can become deadly if a person is exposed for too long. If you see any mold, completely clean the area to remove it. If that doesn’t work, you may need to replace the tray.
Coils
Moisture can condense on the inner coils of an air conditioner. If allowed to sit to long, the moisture may lead to mold growth. The coils need to be checked for mold and leaks at least once a year. This will prevent the mold from becoming to prolific. If you find a crack, call a professional to repair it. The refrigerant inside the coils is toxic and should not be allowed to continue leaking.
Allergens should not be allowed to collect in your conditioner. Dust in the filters not only inhibits proper energy utilization, it can become a breeding ground for mold. Mold can collect on the moist surfaces inside the air conditioner and the spores spread by the fan. Check your air conditioner yearly, repairing any leaks and removing any dust or mold.
