Eek! Don’t Ignore These Signs of Black Mold Growing from Your AC Unit

There are an estimated 1.6 billion air conditioning units in the United States. Only 42% of these homeowners get their air conditioning systems serviced regularly. Without proper maintenance, you put your family at risk for black mold related illnesses.

What Causes Black Mold in Air Conditioner Units?

An air conditioning system uses evaporator coils. These coils cool the air and remove moisture. The moisture in a well-maintained air conditioner passes through a drain and flows from the unit.

Air conditioning systems that have dirty evaporator coils will not drain properly. When this happens, the trapped moisture can begin to grow bacteria and harmful black mold.

Sometimes black mold can invade your air ducts. Trapped moisture and higher summertime temperatures create the perfect conditions for black mold. This is a serious problem that needs a trained professional.

Once black mold is in your air ducts, it’s very difficult to remove on your own.

Removing Black Mold from Air Ducts

Hardware stores sell commercially made mold removal kits. There are also many do it yourself mold killing recipes. If the mold has gotten into the air ducts, however, you are better off hiring a professional service.

Black mold remediation services involve highly trained technicians. These professionals use specialized equipment, including special respirators and eye protection. They wear hazmat suits to keep the mold off of them as they work.
