Air conditioning units and dehumidifiers contain coolant. Homeowners must hire a HVAC technician or Freon removal service before recycling an appliance with refrigerant or coolant.

Refrigerant gas, welding tanks and medical cylinders should be disposed or recycled through the company it was purchased or received from. Contact the company where you made the purchase or search for a list by zip code in the Yellow Pages.

Tanks of refrigerant are not typically found in a household and are not accepted in the household hazardous waste disposal program.

Businesses can recycle refrigerant through specialized companies or choose a licensed environmental services company for proper disposal. See our Business Recycling Directory.
