What happens if you put R134a in a R12 system?

The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used. R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak.

Can you use r134 instead of R12?

Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.

How do I convert R12 to R134a?

Is R12 compatible with R134a?

No. Federal law prohibits topping off an R12 system with a different refrigerant. Your options are to locate some R12, however you must be certified to purchase, and add it with an R-12 recharge hose.

What can I use instead of R12?

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.

What is the best replacement for R12 refrigerant?

The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.

Can you still buy R12 Freon?

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.

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. If you were thinking about getting an R134a system installed, your cost would be around $2,000 to $4,000.

Can you still use R12 refrigerant?

So carmakers were mandated to stop using R12 after the 1994 model year. The current replacement refrigerant is R134a, which serves the same purpose as Freon but is less harmful to the environment.

How much is R12 worth?

What is a pound of r12 worth? “Freon” is a commonly known brand of refrigerant, though it is not a descriptive or generic term. Companies have quoted prices ranging from $35 to $175 per pound for R-22.

When did R134a replace R12?

R12 and 134a are refrigerants used in car air conditioning systems. R12 was used in most cars and trucks until 1995 when it was replaced with 134a. Other than new car manufacturers over the last few years having switched to 1234yf, it’s remained in use ever since.

Which is better R12 or R134a?

Understand that R12 has its advantages. R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. R134a systems require larger condensers and higher operating pressures than R12 systems because R134a doesn’t have as high of a heat transfer rate as R12 (which has a heavier molecular size than R134a).

How much does r134a cost?

Current new. The average current price for new “r134a freon price per pound” is $445 from the last 237 listings.

Is refrigerant finders a legitimate company?

Is R134A phased out?

HFC-134a: a Potent Greenhouse Gas

HFC-134a will no longer be approved for use in new light-duty vehicles manufactured or sold in the United States as of model year 2021 as a result of EPA’s July 2015 final rule under SNAP (July 20, 2015, 80 FR 42870Exit Exit EPA website).

What refrigerant is replacing R134a?

To date, most auto manufacturers are using the hydro fluoro olefin (HFO) refrigerant R-1234yf as the replacement of choice for R134a. The 2013 Cadillac XTS was the first U.S.made vehicle to use the new refrigerant. With a GWP of 4 (instead of 1,430 for R-134a), R-1234yf is more environmentally friendly.

What certification do I need to buy R134a?

Auto body shops wishing to buy the common 10- or 30-pound tanks of R-1234yf or R-134a refrigerant will need to have at least one air conditioning-certified technician by Jan. 1, 2018.

Are all brands of R134a the same?

Yes, all R134A is the same thing, stay away from leak stopper, not to be confused with leak detector, the leak detector is alright to use.

Can I use R290 instead of R134a?

R290 is also an excellent alternative to hydroflurocarbon (HFC) refrigerants R134a (used in refrigerators) and R404a (used in freezers). Using this refrigerant can also reduce overall energy costs by up to 28%.
