There are other important reasons to recover refrigerant besides the law. It’s beneficial for the environment, as it reduces the amount of harmful refrigerants entering it .
Why do we require recovering and recycling refrigerant?
In addition to disseminating low-global-warming-impact refrigerants worldwide, we strictly manage refrigerants during the production, after-sales, and other stages, and we recover, recycle, and destroy refrigerants at the end of air conditioner life so that we can reduce environmental impact throughout the entire life ...
What do you need to recover refrigerant?
- Start with all valves closed (recovery cylinder, recovery machine, manifold, hoses.)
- Setup hoses as shown in the diagram.
- ZERO/TARE the refrigerant scale.

What is the fastest way to restore refrigerant?
In extreme ambient temperatures, submerging the recovery cylinder in ice or ice water is the most effective way to keep a cylinder cool. A well-cooled cylinder ensures a fast recovery process. It is important to note that rapid heat buildup can be an indication of non-condensable gases.
How much does it cost to recover refrigerant?
Residential Air Conditioner Freon Refill Cost
Freon costs an average of $150 for a Freon refill. Most people pay between $100 and $350 for a refill, depending on the size and type of your HVAC unit. Older large r22 units can reach $600 or more. A 25lb jug of r410a runs $75 to $175.

How long does it take to recover refrigerant?
Usually, it takes about 10 to 30 minutes of chilling to produce some considerable tank cooling, depending on present conditions. Keep in mind, the greater the quantity of refrigerant in the tank, the longer the process.
What do they do with old refrigerant?
In general, if the refrigerant is not contaminated it can be recycled and reused . You can typically take the noncontaminated refrigerant back to the wholesaler for exchange. If the refrigerant is contaminated, you’ll need to send it to a reclamation facility.
How much refrigerant can a recovery tank hold?
NEVER Exceed Refrigerant Recovery Tank Limits
By law, a tank can only be filled to 80% capacity and must be kept under 122°F. It is recommended to fill to 2 lbs less than the 80%. For example, a 30 lb cylinder can hold 22 lbs of refrigerant and a 50 lb cylinder can hold 38 lbs of refrigerant.
Do you need to recover 134a refrigerant?
If you need to crack open your A/C for repairs or parts replacement, then you need to recover the refrigerant first . You should never vent R134a into the atmosphere or the EPA and the Tree Huggers will kick the crap out of you.
What happens if a recovery cylinder is filled with liquid refrigerant and allowed to warm?
Do not overfill the cylinder. Liquid refrigerant will expand as its temperature is increased . If the cylinder somehow becomes completely full of liquid, the pressure can increase dramatically with a relatively small increase in temperature.
What refrigerants do not need to be recovered?
Co2 refrigerant R-744 (Carbon dioxide) is a very high-pressure refrigerant and generally does not need to be recovered.
When recovering refrigerant from small appliances you must recover?
