Can I add R134a to a R12 system?
To be able to use R134a in an R12 system, the R12 system needs to undergo a retrofitting so that it's able to handle and process R134a refrigerant. This also means that some refrigerant conversion needs to be done in order to drop R134a into a R12 system. via
What refrigerant is compatible with R12?
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. via
How do I switch from R12 to R134a?
Is it legal to sell R12 refrigerant?
Is it legal for me to sell? 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. via
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. via
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. via
How much does it cost to convert R12 to R134a?
It will generally cost you about $200 to have a mechanic convert an AC system for you. If you want to replace a vehicle's AC system, it will cost between $1,500 and $4,000 with an average cost of $2,750. If you decide to have a professional work on your car, you will have several options for where to get the work done. via
How can you tell if you have R12 or R134a?
To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is R134a. And you can also look for R134a adapters, which would be located on the charge parts. via
What is the ratio of R12 to R134a?
A charge level between 75% and 85% is recommended when converting from R12 to R134a refrigerant. via
Is R12 colder than 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. via
Can anyone buy 410a refrigerant?
R410a IS NOT one of those. ANYONE can purchase and handle 410a. NO certification or license needed. This 50-question exam covers proper safety, handling, and application of R-410A refrigerant systems. via
Can I sell my R22 refrigerant?
R22 refrigerant is illegal to import and manufacturer in the U.S. But it's not illegal for anyone to buy R22 freon. And it's not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company. via
What is a 609 certification?
Section 609 of the Federal Clean Air Act requires technicians who service motor vehicle air conditioning “MVAC” systems to be certified. Required to service motor vehicle A/C systems. Required to purchase small containers (under 20 lb) of regulated refrigerants. via
What component Cannot be flushed?
Accumulators, receiver driers, lines and hoses with filters and mufflers CANNOT be flushed and must be replaced. via
Can you mix R12a and R12?
Unfortunately I'm now out of R12, and this time I'm going to try a substitute, environmental friendly Red Tek R12a refrigerant. The manufacturer claims it's compatible with R12 and there are several positive reviews on it. via
Can I use R12a in a R12 system?
Unlike R-134a, HC-12a is completely compatible with the hoses and oils used in R-12 systems, making the conversion much easier to accomplish. HC-12a is also patent-free due to its non-synthetic nature. via
Can I replace R12 with r600?
R600a is a good replacement for R12
With regard to R600a, it has a lower molecular weight, 58.1 kg/kmol in comparison to R134a, 102 kg/kmol, which results in a lower charge for Isobutane. R600a also has lower operating pressures than R134a, improving reliability and extending life of the compressor. via
What year did R134a replace R12?
Vehicles manufactured before 1994 used R12 for air conditioning. Vehicles older than 1994 started using R134A instead of R12. So what if you have a car that was made in 1994 or even earlier? Well, if you have a car that old, you have two options. via
What happens if you put R134a in a R22 system?
Using R134a in Systems Designed for R22
If you have a home or auto air conditioner designed to work with R22 refrigerant, and the system needs a recharge, a number of issues prevent the direct substitution of R134a. R134a swells the rubber components in the refrigeration system and causes leaks. via
Do cars still use freon?
The U.S. Environmental Protection Agency (EPA) has gradually phased out the R-22 refrigerant, commonly known by its trade name of Freon, also called HCFC-22. Vehicles manufactured before the 1994 model year used R-12 (also referred to CFC-12 or Freon). Newer vehicles rely on R-134a refrigerant, also known as HFC-134a. via
Is refrigerant a liquid or gas?
The refrigerant, a chemical compound that changes easily from liquid to a gas. When the refrigerant is pushed into the compressor, it is a low pressure gas. via
How do you know what type of refrigerant?
To know which type of refrigerant your air conditioner uses, take a look at the label on the compressor unit outside. It'll clearly tell you which type of refrigerant the unit uses. The newer type is R-410A, and the older type that I've been talking about is R-22, also identified as HCFC-22. via
How much PAG oil do I put in a compressor?
Here is the amount of PAG oil needed for its smooth operation by different AC components: Compressor = 1.4 ounces. Evaporator = 1.5 ounces. via
When retrofitting a system from R12 to R 134a what is required to be done?
Sanden Procedure for Conversion from R-12 to R134a
Recover all R-12 refrigerant from the vehicle's A/C system. Evacuate the A/C system for at least thirty (30) minutes to a vacuum of 29 in. Hg, using R-12 equipment, to remove as much R-12 as possible from the residue mineral oil. Remove all R-12 service equipment. via
When was R12 phased out?
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. via
How cold can r134 get?
That fact explains why compressor manufacturers limit the condensing temperature for R407C to around 145–150°F (60°C–65°C) whereas for R134a compressors, the top limit for condensing temperature is 158–175°F (70–80°C) for air condi- tioning applications. via
