Summary
This informational bulletin is for Korea to see normal operation of A/C compressor.
Condition
Some customers may comment on the following:
- A/C compressor may intermittently exhibit higher than usual levels of noise and vibration
- Occasionally a booming sound may be heard between 1500 to 2000 engine RPM
Cause
The A/C compressor working load increases during high ambient temperatures and full A/C load conditions needed to cool the vehicle interior. Under these conditions, it is normal for compressor noise levels to increase.
Correction
If A/C system performance test and pressures are correct, the compressor noise is a normal condition of the system. Many A/C compressors replaced under warranty and returned are NTF (No Trouble Found). Compressor replacement will not improve the noise level.

- Eliminates moisture buildup and acid from A/C system to help extend A/C system life
- Contains acceptable amounts of ingredients: 14oz R-134a Refrigerant (1,1,1,2 Tetrafluoroethane, CAS# 811-97-2) & 8oz of synthetic lubricant enhancer, conditioner, with leak sealer.
- Contains R-134a gas which is acceptable for use in motor vehicle A/C (MVAC) systems
- UNIVERSAL - ZeroR AC Refrigerant is a hydrocarbon that safely bonds with chemicals like R134a, R1234YF and R12. We can only advertise this product to be used in R134a systems due to EPA regulations in the USA on both R12 and R1234YF systems. EPA also prohibits mixing refrigerant types. See the description for all legal disclaimers.
- EASY - This product installs just as easily as any R134a products. Cans even have R134a threads and the majority of R134a can taps will work for these cans.
- 6oz CANS - Refrigerants are compressed gasses and are measured by weight, not by liquid volume such as water. All gasses compress differently and produce a different weight. ZeroR AC Refrigerant is low weight compared to R134a, but its performance is equal to 16oz of R134a.
- ECO FRIENDLY – ZeroR AC Refrigerant is a 100% Natural gas unlike R134a, R1234yf and R12.
- SAFE – ZeroR AC Refrigerant has a class 2.1 flammability rating just like the new R1234YF which is now used in 100% of newly manufactured vehicles. Under normal operating conditions this product presents no danger to its users when handled properly and used in systems approved for flammable refrigerants.
