As temperatures heat up, air conditioners are kicking on. Many of us don’t think to have them checked out before summer, but we should. What's lurking in our air conditioners can make us sick.
Moisture can build up in air ducts, giving mold and mildew a place to grow. Just turning on the air conditioner can spread it through your house.
Dust can also be a problem. It accumulates in your air ducts if the filters aren’t changed often.
Experts say all of that dust and mold can make you sick, especially if you already have allergies.
They suggest you have your air conditioner and ductwork cleaned every five to ten years and checked and sanitized for mold and mildew every two to three years. They also say to change your air filters at least once a month.
