Ozone friendly refrigerant HFC134a.....
According to my repair manual the refrigerant is HFC134a.
No
the sys has too much lubricant
the sys has too much lubricant
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.
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
Disposable refrigerant containers are only used for virgin refrigerant.
Can't do it. The lubricant is mixed in with the refrigerant. Converted to air it would be running dry.
Refrigerant compatibility refers to different types of refrigerant being compatible. Not all air conditioners use the same type of refrigerant and not all refrigerants are compatible in every air conditioner.
If you used a recovery equipment to recover CFC-12, you need to separate the lubricant from the recovered refrigerant.
