You cannot legally dispose of Freon yourself by releasing it into the air. Under Section 608 of the Clean Air Act, venting refrigerants is a federal violation, and the EPA requires that Freon be professionally recovered using certified equipment before any appliance containing it is scrapped or sent to a landfill. In practice, this means you need to either hire a licensed HVAC technician or bring your appliance to a facility equipped to handle refrigerant recovery.
Why Freon Can’t Go in the Trash
Freon is a brand name commonly used for refrigerants like R-22 and R-410A, the chemicals that cycle through your air conditioner, refrigerator, or freezer to produce cold air. R-22, the most widely used residential refrigerant for decades, has a global warming potential of 1,810, meaning one pound released into the atmosphere traps as much heat as 1,810 pounds of carbon dioxide over a century. It also damages the ozone layer, which is why its production was phased out in the U.S. in 2020. R-410A, its common replacement, doesn’t harm the ozone layer but is actually worse for climate change, with a global warming potential around 2,088.
Beyond environmental damage, Freon is directly dangerous to handle. Inhaling refrigerant can cause throat swelling, breathing difficulty, irregular heart rhythms, and severe lung damage. Skin contact with liquid refrigerant causes burns and tissue damage. The compound is especially lethal when concentrated, and accidental exposure during amateur removal attempts is a real risk.
What the Law Requires
EPA regulations under 40 CFR Part 82 lay out two tracks depending on the type of equipment you’re disposing of.
Large systems that get dismantled on-site, like central air conditioning units, commercial refrigeration, and chillers, must have their refrigerant recovered by a technician before disposal. These technicians need EPA Section 608 certification: Type II for high-pressure systems (most residential and commercial AC), Type III for low-pressure systems like large chillers, or Universal certification to work on everything.
Appliances that typically enter the waste stream intact, like household refrigerators, freezers, window AC units, and car air conditioners, follow a different rule. The final person in the disposal chain (the scrap metal recycler, landfill, or appliance recycler) is legally responsible for making sure the refrigerant gets recovered before the unit is crushed or buried. If someone drops off an appliance that’s already been drained, the receiving facility must keep a signed statement on file with the name and address of whoever recovered the refrigerant and the date it was done.
One important exception: if you’re recovering refrigerant from a small appliance, window unit, or car AC specifically to prepare it for disposal, you don’t need to be a certified technician. However, the recovery equipment you use must meet the same EPA performance standards as professional servicing equipment. In other words, you can’t just cut a line and let the gas escape.
Your Options for Getting Rid of It
Hire an HVAC Technician
This is the most straightforward path if you’re replacing or decommissioning a central AC system, heat pump, or any large unit. A technician with EPA 608 certification will connect recovery equipment to your system, pump the refrigerant into a storage cylinder, and either reclaim it for reuse or send it for proper destruction. Labor for this type of service typically runs $200 to $700 depending on the system’s complexity and how much refrigerant is involved. If you’re also having the system replaced, refrigerant recovery is usually bundled into the installation cost.
Use an Appliance Recycling Program
If you’re getting rid of a refrigerator, freezer, or window AC, your easiest option is a recycling program that handles the refrigerant for you. The EPA’s Responsible Appliance Disposal (RAD) program connects utilities and municipalities that commit to best practices for recovering Freon and other harmful materials from old appliances, including the insulating foam (which also contains greenhouse gases in older models). Many utility companies will pick up your old refrigerator or freezer for free as part of energy efficiency programs, and they handle the refrigerant recovery as part of the process.
To find a participating program, search for RAD partners in your state through the EPA’s website, or call your electric utility and ask if they offer appliance pickup or recycling.
Drop It Off at a Scrap Recycler or Transfer Station
Many scrap metal recyclers and municipal waste transfer stations accept appliances containing refrigerant. Under federal law, the facility takes on the legal responsibility for recovering the Freon before processing the unit. Call ahead to confirm they accept refrigerant-containing appliances and ask about any fees. Some facilities charge a small disposal fee; others accept them for free because of the scrap metal value.
If you’ve already had the refrigerant professionally removed before dropping off the appliance, bring documentation. The facility is required to keep a signed statement showing who recovered the refrigerant, their address, and the date of recovery.
Retailer Take-Back
When you buy a new refrigerator, freezer, or AC unit, many retailers will haul away your old one as part of the delivery. Big-box stores and appliance dealers typically have contracts with recycling facilities that handle the refrigerant recovery. This is often the lowest-effort option if you’re already buying a replacement.
What You Should Never Do
Cutting refrigerant lines, puncturing sealed systems, or simply leaving an old unit outside with its lines open are all forms of venting, which is illegal regardless of the refrigerant type. This applies to every refrigerant, not just ozone-depleting ones like R-22. The prohibition covers newer refrigerants like R-410A and R-134a as well.
Pouring liquid refrigerant down a drain or putting pressurized canisters in household trash is also prohibited. Small disposable refrigerant cylinders (the kind used for car AC top-offs) should be completely emptied of both liquid and vapor, then taken to a metal recycling facility. Some local hazardous waste collection events accept partially full canisters.
If You Have Loose Refrigerant Cylinders
Contractors sometimes end up with partially used cylinders of refrigerant, and homeowners occasionally inherit them when buying a house or cleaning out a garage. Full or partially full cylinders of R-22 still have value because the refrigerant is no longer manufactured but remains in demand for servicing older systems. An HVAC supply house or licensed technician may purchase it or accept it for reclamation. For other refrigerants, contact a refrigerant reclamation company, which will test and purify the refrigerant for resale or arrange for its destruction if it’s contaminated.
Never attempt to empty a pressurized cylinder by opening the valve outdoors. Even in a well-ventilated area, this constitutes illegal venting and can result in EPA fines.
