Is your air conditioning system making you sick?

Share This Post

It’s a common concern, but let’s set the record straight. No conclusive evidence suggests that a properly maintained air conditioning system can directly cause illness. However, certain factors, such as neglected maintenance, dirty filters, and excessive moisture, can contribute to health issues by circulating irritants and pathogens. 

In this article, we’ll delve into the details of what some refer to as “air conditioning airborne pathogens sickness” and provide tips on how to avoid potential problems.

Understanding the Role of Air Conditioning

Cold air from your air conditioner itself doesn’t make you sick. However, air conditioning can indirectly affect your health in several ways:

  1. Airflow: Air conditioning units circulate air throughout your home, which can move particles like dust, dander, mold, bacteria, and viruses. It’s important to note that having a primary AC filter ensures that the air coming out of your forced air system is often cleaner than the air it draws in.
  2. Mold: Poorly maintained air conditioning systems can create ideal conditions for mold and bacteria to thrive, especially in dark and moist environments.
  3. Cold Air and Dryness: Cranking up the AC can reduce indoor humidity levels, potentially causing dryness and irritation in your eyes, nose, and throat. While this might affect a small portion of the population, it’s not a widespread concern in most areas where high humidity is the primary issue.

Common Symptoms of Air Conditioning System-Related Health Issues

Symptoms of air conditioning-related discomfort can vary from person to person but typically include:

  • Dry, itchy eyes, nose, and throat
  • Dry skin
  • Coughing or wheezing
  • Fatigue or dizziness
  • Nasal congestion
  • Headaches

If you experience increased respiratory problems that you suspect may be related to your AC, it’s advisable to consult a healthcare provider. Maintaining exceptional indoor air quality can help reduce these symptoms.

Preventing Air Conditioning-Related Health Issues

Homeowners can take proactive steps to prevent respiratory problems associated with air conditioning:

  1. Regular AC Maintenance: To lessen the chance of moisture accumulation, which can promote the growth of bacteria and mold, schedule routine AC maintenance.
  2. Change Your Air Filter: Replacing your home’s air filter every 1-3 months significantly reduces airborne irritants, enhancing indoor air quality.
  3. Optimal Humidity Levels: Maintain indoor humidity levels between 30-50%, as the EPA recommends, to prevent bacteria and mold growth. If you spot mold, take immediate action with the help of a mold remediation expert.
  4. Keep Your Space Clean: Regularly clean, sweep, dust, and vacuum your home to reduce dust, dander, and pollen levels, minimizing the potential for irritants to spread via your air conditioner.


Even though your air conditioner isn’t making you sick, skipping routine maintenance could put your family at risk for health problems and high levels of airborne particulates. Your HVAC system may become crucial for enhancing indoor air quality and ensuring a healthy living environment by prioritizing routine maintenance and cleanliness.
