According to occupational and health scientists asked by Gizmodo, air conditioners can make you sick. Yet it is rare if one actually does and it’s okay to continue using your A/C. One doctor said one of the issues is condensation and for the A/C to spread that bacteria into the air. He also said that mold can be a big issue because it can trigger an allergic response. Another doctor said dry air conditioners do not cause disease while wet ones are more risky.
