SOURCE: can R12 be used to add freon to a refrigerator

No it can not. You have different oil in the different refrigerant. Really isnt recommended to repair at all.

SOURCE: how to refill freon gas into a compressor of a

Unless you have a line tap valve you cannot get into the system, The question is why?. Do you want to refill with freon?. Have you had a leak?. If so has it been repaired?. If it has do not forget to put the system under a deep vacuum first otherwise there will be moisture in the system and this will freeze at the expansion point creating a high pressure before it causing the compressor to cut out. Let me know why you want to put freon in first. then I may be able to help.

Can 134a refrigerant be put into a R12 a/c system?


no --it cannot. R12 gas operates at a far lower pressure that r134a so if you want to use r134a gas you will have to replace compressor ,evaporator and condenser and have a cooling fan for the condenser fitted

Ac problem at idle after converting over to 134a from r12


to convert from r12 to r 134 a the entire system has to be changed
that is condensor, compressor, evaporator, hoses ,the lot because r134a runs at much higher pressures than r12 ( nearly 3 times higher in psi)
it needs different gauges and has different fill connections so that the gasses cannot be mixed
to make it worse the oil used in the compressor is different because of the different gas and is not compatible with the r12
there was nothing wrong with r12 gas but companies and customers were "hoodwinked" into believing that the r12 was bad for the atmosphere and r134a was the answer
just as you have been " hoodwinked" by the person into getting a gas change over without being fully informed of what was involved and why
with r134a gas there has to be a fan in front of the condenser that works immediately the ac is switched on as the temp of the gas being converted back to liquid is much higher because of the higher pressure need to convert it back from gas to liquid
without that fan the system starts to circulate gas and so the evaporation of the liquid at the evaporator in the car is lost and no heat from the car is transferred back outside
what it means is this --- if you can get r12 gas , change the compressor back to an r12 compressor, have the system completely flushed, vacuumed down for at least 1/2 hour and then refill with r12
If on the other hand you have to use r134a because that is the only compatible compressor available then the evaporator , hoses and condenser have to be changed as well and that means a new ac kit basically
find yourself an accredited ac specialist shops and get quotes

Convert r-12 to r134a


if the compressor is r12 and want to use it with 134a you need to change the oil in the compressor before you do the change, and while you change if make sure that he 1st 50oz of gas you charge it with the compressor off. its recommended r12 because it works better at high temperature.

Refill ac


first you must determine if you have r12 or r134a to find out find the compressor follow the 2 hoses on should go tward the radiator and one should be heading back tward the firewall. you should find a valve on each line. now to determine which coolant r12 will have a small valve that looks like the valve on a bicycle tire. r134a will have a bigger valve that has a ring around it as to accept a snap clip. your local parts store should be able to show you the difference. if you have r12 then my suggestion would be to have a shop do the retrofit for you for around 100/150 dollars. hope this helps

Hi,my compressor is running on r12 gas, is it possible to repair it


Good day,
The problems that occur on R12 systems are no different than the newer R134A units.If it involves using R12 it would be a little more expensive, but since they use approx. 6 to 8 ounces it really isn't that bad.

What is the refrigerant in my 1991 LS400 Lexus?


R12 is not sold no longer so look on the compressor for a tag of what freon to use. Conversions kits are sold for older cars to use R134a

Need a replacement compressor < 8 " high for older refrigerator


How can you have a R134a Compressor that is 32 years old. That gas was not even available then. What you are asking is impossible, unless you are asking can you change from possibly R12 to R143a. The answer is yes but it would probably be too costly. you see R12 ran with mineral oil whereas R134a runs with Polyolester oil. the system would have to be completely flushed out of old oil, and the expansion device ( capilliary tube ), would have to be changed and cut to the correct length to appropriate the correct displacement of gas.

Need replacement R12 refer and freezer compressors. OEM Americold compressors no longer available. URS 48 DT model should also work. Thank you.


You can use R134a compressors with the Poly oil in them and use R12 or R134a (flush the remaining old mineral oil out of the system first). Match your BTU requirements.
