Air conditioners, both window units and installed, contain Freon, a substance which can contaminate the groundwater and is poisonous to humans and pets.
It is illegal to place air conditioners in the trash. It is also illegal to cut a freon line and evacuate this substance onto the ground.
Air conditioners, refrigerators, dehumidifiers or items with refrigerant are accepted at both of the Keep Northern Illinois Beautiful Recycle Centers. There is a $20 fee for the removal of the refrigerant by a licensed professional. Cash or debit/credit card is preferred.
