FAQ:

Q: Does R-134a have a phase out date?

A: So, to answer your question the phase out date for R-134a is set for 2023. However, with that being said there is one important thing to point out. Unlike with the CFCs and HCFCs phase-outs of the past the R-134a phase-out is not seeing a mandatory reduction in imports or production.

Q: Does AC Stop Leak sealer work?

A: The AC stop leak works when injected into the system as a liquid. This liquid reaches the leaky area and becomes a coating there that works as a seal to prevent further leakage. Now, the sealer liquid turns into a layer only at the leak because the moisture is present there. When the sealer reacts with the moisture, it becomes a seal.

Q: Does Freon leak stop or Freon leak sealer work?

A: These type of stop leaks rarely work due to the high pressure in your air conditioning system. One can of Super Seal is all you need to seal pinhole-sized leaks in your system. However, if the system cannot hold a charge for 24 hours, the leak is too large and probably needs manual repair. ….
