is an (and in this case, the only other) isotope, it is designated with the letter “a”. The same type and amounts of atoms are used..they are just attached differently (CF3-CH2F) is all.

R134a

, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.

Can you use R134a in a HFC-134a system?

What happens when you mix R12 and R134a?

R134a

systems work at higher discharge-side pressures than R12

systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

Why is R134a being phased out?

HFC-134a

: a Potent Greenhouse Gas

It is the most abundant HFC in the atmosphere. 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 42870 ).
