Ozone friendly refrigerant HFC134a.....
According to my repair manual the refrigerant is HFC134a.
No
When recovery recycling equipment is used to remove refrigerant from a mobile AC system, it typically removes a small amount of lubricant along with the refrigerant. The exact amount can vary depending on the system design and the condition of the components, but generally, about 1 to 3 ounces of lubricant may be recovered. It's essential to monitor and manage this lubricant to ensure proper system function and prevent damage.

414B refrigerant is compatible with polyolester (POE) oil, making it suitable for use in systems that employ this type of lubricant. However, it's essential to ensure that the entire system is compatible with 414B and that any necessary adjustments or retrofits have been made. Always consult the manufacturer's specifications and guidelines before making any changes to a refrigerant or lubricant in a system.
The lubricant needs to be collected and properly handled by placing it in a designated container for lubricant disposal. It should not be mixed with other materials or released into the environment.
Yes, R134a and HFC-134a refer to the same refrigerant, which is 1,1,1,2-tetrafluoroethane. Therefore, if a vehicle specifies HFC-134a, you can use R134a as it is the same chemical compound. However, ensure that the refrigerant meets the manufacturer's specifications and that it is handled properly during servicing.
PAG (Polyalkylene Glycol) refrigerant lubricant is a synthetic oil commonly used in modern refrigerant systems, particularly those employing R-134a and R-1234yf refrigerants. It is designed to provide excellent lubrication, thermal stability, and compatibility with various materials used in HVAC and automotive applications. PAG lubricants have good moisture resistance and help improve the efficiency and longevity of the compressor systems. However, they can be hygroscopic, meaning they absorb moisture from the air, which can be a concern if not handled properly.
Generally very little, if any
During the AC recovery process, typically about 80-90% of the lubricant in the system is removed along with the refrigerant. The exact amount can vary depending on the system design and the efficiency of the recovery equipment used. It’s important to replace the lubricant after recovery to ensure the system operates effectively and to prevent damage. Always refer to manufacturer specifications for precise lubricant quantities.
