However, if you have to recharge the AC once a year or more because its not cooling anymore, there is likely a leak somewhere, and you should have it checked. Don't overfill the system. When an engineer creates an air conditioning compressor, he constructs it to precise tolerances, which necessitates the use of a specific type of lubricant viscosity, friction characteristics, and wear additives in order to get the desired results. Suction hose: 0.3 oz. of supercoolness The price range is $2-$12 per item. Because of this, manufacturers guarantee that replacement parts, such as compressors, are shipped with a predetermined amount of oil. How much pag oil you add will depend on the size of the accumulator. Using the incorrect oil might cause the compressor and other A/C components to fail, as well as other problems. The compressor system of this kind is lubricated using Polyalkylene Glycol (PAG) Oil. It is critical to choose the right compressor oil for your car in order for it to run smoothly on the air conditioning. Always pay attention when adding fluids because too much will cause overheating which could lead directly into costly repairs down the line such as vandalism caused by collateral damage from firefighting efforts.. on February 13, 2005 Initiation date: May 2003, Junior Member Chesapeake, Virginia, United States of America The number of posts is 189, and the number of likes is 0. , or what has been done to them in the name of madness. The process of refilling oil in the AC system is fraught with difficulties, and doing so incorrectly can result in additional damage. If you just had a new compressor installed, keep in mind that many new compressors are pre-filled with oil. Should I add oil to a new air compressor? It will be awhile before I need AC here in the N. East, as Spring has taken the year off. CAUTION: Do NOT overfill the the A/C system with too much compressor oil. Here is the amount of PAG oil needed for its smooth operation by different AC components: Its suggested to flush the whole system before adding oil or refrigerant. Oil logged in the evaporator will coat the inner wall of the coil and reduce heat transfer through the walls. Adding the right quantity of oil to your air conditioning system is critical when installing a new compressor or any other components in your system. It is exerting considerable effort to compress the refrigerant in the system, and it requires oil to assist with heat regulation and lubrication, among other things. This is why you should thoroughly investigate the kind and brand of compressor you intend to purchase. After that, you may have the device sucked to remove any air and moisture, either by returning it to a mechanic shop and using their recovery machine, or by using your own vacuum pump. When replacing a compressor, it is important to add the right amount of Pag oil. Using these PAO oils is permitted by certain manufacturers, although the vast majority do not. You can not run the engine without Freon in it. So, checking the manual is a good idea to be sure of the exact amount and to avoid over- or under-filling the system.
