How to Handle Allergies Inside Your Home

The last thing you want when trying to stay cool indoors from the hot, triple-digit temperatures in summer is to start coughing and sneezing because of allergies from your AC. Unfortunately, some people can experience air conditioning allergic reactions.

However, the allergic reaction is not from the cold air being blown into the house. Rather, it is caused by one or more allergens in the indoor air.

What Are Allergens?

Allergens are various types of harmless antigens that the body’s immune system perceives as a threat, so it triggers an immune system response, such as:

  • Runny Noses
  • Watery, Itchy Eyes
  • Coughing
  • Sneezing

What Are Some Common Allergens?

The most common allergens people are sensitive to include:

  • Pollen
  • Dust
  • Mold
  • Mildew
  • Pet Dander
  • Dust Mites
  • Pollutants
  • House Plants
  • Chemicals Used in Household Cleaning Products

Reasons You Experience Allergies from Your AC Inside a Home

As cool air is circulated throughout your house, it easily spreads allergens to every part of the home. So, if you are sneezing, coughing, or experiencing other allergy symptoms, you need to track down the source of the allergens to determine how to best resolve the issue. Start by checking the following parts of your air conditioning system.

Is there an air filter in the air return, and is it dirty?

Running your air conditioning without an air filter is never recommended. Dust, dirt, and debris can get inside the cooling system. When it does, it can cause operational issues, shorten its lifespan, and spread the dust, dirt, and debris throughout the ductwork and the home, triggering your allergies.

When the air filter is dirty and not changed regularly, it can become clogged and no longer remove allergens from the indoor air. Therefore, you want to inspect your air filter monthly and change it whenever it is dirty.

What quality is the air filter?

Low-quality air filters will not filter out allergens that well. You want a decent air filter that does not restrict airflow yet can remove allergens from indoor air. To choose the best air filter for your AC system, ask your AC technician to recommend one.

Do you smell mildew when the AC is running?

If you do, chances are your home also has mold. Both mold and mildew thrive in humid environments, including inside your AC system. You should have your AC technician help find the source of the mold and mildew so it can be eliminated.

Do you have air leaks in your home?

Air leaks can occur around doors and windows, allowing pollen and other allergens to get inside. Another cause of air leaks is in your ductwork. You will want to resolve air leaks to prevent outside air from getting into the house.

When was the last time your AC system was serviced?

Regular maintenance is essential to help prevent problems that could contribute to allergens inside your home. For example, when the water drain on the AC is clogged, it can back up inside the unit, resulting in higher humidity levels that can lead to mold and mildew problems.

Your AC may also require cleaning to remove dust, dirt, and debris from the outside unit so that it doesn’t get into the system and into your home.
