How do I uninstall R12?
The only way to reliably convert from R-12 to R-134a is to remove the compressor and flush out all the old oil with the new type of oil; then replace the old Receiver-Dryer or Accumulator with a new one; then flush out all the lines, the evaporator, and the condensor with special cleaner then vacuum to a steady vacuum; …
Is R12 illegal?
R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.
What happens if you put R12 in a R134a system?
R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. R12 systems used mineral oil, but unfortunately mineral oil doesn’t dissolve in R134a. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil.
Can I replace R12 with R134a?
R134a is a safer replacement for R12. Another major difference is the type of oil both refrigerators require. R12 is compatible with mineral oil, and most R12 systems use this. R134a uses Polyalkylene Glycol (PAG) oil.
Can R12 still be purchased?
Anyone with the required EPA R-12 certification still can buy the 1-pound cans at auto-parts stores, but the cans are kept in the back and guarded like gold.
Is R12 toxic?
A) Freons are very toxic when inhaled in high concentrations and/or for extended periods. At lower concentrations or brief exposure, freons may cause transient eye, nose, and throat irritation.
Can I sell my R12 refrigerant?
Yes, you can still sell R-12 and other CFC refrigerants. Although these refrigerants can no longer be manufactured, it is perfectly legal to sell to an EPA certified buyer.
Can you still recharge R12?
No you can not recharge an AC system equipped with R-12 unless you are a licensed technician. You can convert your AC system to R-134 yourself, once the R-12 is dealt with correctly.
How much does it cost to convert R12 to R134a?
If you have a professional convert the R12 to R134a, you may spend about $250 for the entire service. However, this is much more cost-effective than replacing the entire air conditioning system.
What replaces R12 refrigerant?
R134a
There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.
Which is better R12 or R134a?
R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. As a result, a perfectly functioning R12 system will blow colder and reduce temperatures faster than a system that was converted to R134a.
Why did they get rid of R12?
In conclusion folks R-12 Freon was banned due to the damage that it caused to the Ozone layer. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.
How do you flush an R-12 system?
Take the vehicle to a repair shop licensed for A/C work that can evacuate the system of R-12 and recover it properly. Using an A/C flush kit, flush the evaporator and condenser to remove any remaining mineral oil in the system. Empty oil from the compressor and flush oil from high-pressure and suction lines.
When did they stop using R12 in cars?
By international agreement in 1987 (the Montreal Protocol), the use and production of CFCs such as R12 began to be phased out, with automobile manufacturers required to stop using it by the end of the 1994 model year. International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.
How do you convert R12 to R134a?
Steps To Convert R-12 to R-134a Take the vehicle to a repair shop licensed for A/C work that can evacuate the system of R-12 and recover it properly. Using an A/C flush kit, flush the evaporator and condenser to remove any remaining mineral oil in the system.
Can I use R12 instead of R12 in my car?
R12 Replacement for the Vehicles In most of the vehicles, the air conditioners use the R12 refrigerant, which is now getting difficult to get and expensive. For vehicles also the most appropriate alternative is R-134a refrigerant. It has been approved by all the vehicle manufacturers for replacing the R12 refrigerant.
