Can AC Make You Sick?

Can Air Conditioning Make You Sick?

While air conditioning itself doesn’t inherently make you sick, certain factors associated with its use can contribute to health issues. Poorly maintained AC units can harbor dust, mold, and bacteria, which can be circulated throughout your home, leading to respiratory problems, allergies, and other health issues in addition to needing ac repair. Additionally, excessive cooling can cause discomfort and exacerbate certain conditions, such as dry skin and respiratory issues.

Factors Contributing to AC-Related Illnesses

  1. Lack of Maintenance: Dirty filters and coils can harbor dust, mold, and bacteria.
  2. Humidity Levels: Improper humidity control can lead to dry air or excessive moisture, both of which can cause health problems.
  3. Temperature Fluctuations: Sudden changes in temperature can stress the body, leading to discomfort and illness.

    Coughing can be a common issue associated with air conditioning use. The primary reasons for this are dry air and the circulation of allergens and irritants.

    Causes of Coughing from AC

    1. Dry Air: AC systems can reduce indoor humidity, leading to dry air that irritates the throat and respiratory tract.
    2. Allergens: Dust, pollen, and other allergens can be circulated by the AC, triggering respiratory responses.

    Tips to Prevent AC-Related Coughing

      Risk Factors and Prevention

      • Ensure AC units are clean and free of mold and bacteria.
      • Avoid drastic temperature changes to reduce stress on the respiratory system.
      • Seek medical advice if experiencing persistent respiratory symptoms.

      Several of my HVAC units were struggling to cool given the 95+ degree temperatures. I called Hay’s and they sent Brad out to see what was going on. Hay’s installed the HVAC units 15 years ago. Brad wore a mask. He cleaned all of our units and added refrigerant. Brad worked swiftly and efficiently.

      Brad was AMAZING!!! When our air conditioner stopped working last night, we were worried that it would be days before someone would be out to look at it. We woke up and the house was 10 degrees warmer than when we went to bed. We were told that someone would be out at noon…
