- Normally you do not need to add oil to your AC compressor after it is installed, unless your installing a new compressor or if their is a leak in you AC system.
- If you do need to add oil check the compressor specifications on how much oil is needed.
Thus, Can you put too much oil in AC compressor? If you add too much oil to the system, it may pool in various places of the system and can coat the inner walls of the evaporator and condenser coils. This will diminish their ability to absorb or dissipate heat, thereby bringing down the overall cooling performance.
Additionally What happens if your AC compressor is low on oil? Without enough oil in the crankcase to properly lubricate the load-bearing surfaces, wearing and scoring happen. There just isn’t enough refrigerant mass flow in the system to return oil to the compressor as fast as it is pumped out. Without enough oil, those surfaces become visibly scored or worn.
Where do I put oil in my AC compressor? There should be a valve on the rear of the compressor. Unscrew it to let the old oil flow out. Add new oil. Check your owner’s manual to see how much oil your specific compressor needs to function.
Can low oil affect air conditioning? Oil helps cool and lubricate the compressor, and seals every nook and cranny to prevent leaks. Without oil, friction will cause the compressor to heat up and will cause the air conditioning system to shut down.
How do you know if your AC has too much oil?
Inefficient Cooling The most glaring sign of an overfilled AC system is poor cooling because an internal coating forms resulting in reduced heat transfer. For instance, you might notice that it’s taking way too long to cool things or your windows stop defogging properly.
What happens if AC compressor has no oil?
Without enough oil in the crankcase to properly lubricate the load-bearing surfaces, wearing and scoring happen. There just isn’t enough refrigerant mass flow in the system to return oil to the compressor as fast as it is pumped out. Without enough oil, those surfaces become visibly scored or worn.
Where do I put the oil in my AC compressor?
Use of an AC compressor oil injector to refill the compressor. Another way of adding oil to the compressor is by use of an oil injector. Simply fill it to the required level and clip the injector’s valve to your compressor’s lower side pressure valve. All that remains is to push in the oil slowly.
What happens if too much oil in AC system?
Oil logged in the evaporator will coat the inner wall of the coil and reduce heat transfer through the walls. This will cause a loss of capacity and poor performance. The compressor will be robbed of some of its crankcase oil and will run with a lower-than-normal oil level.
How do I fill my AC compressor with oil?

How do I add oil to my air conditioner?
After that, you can follow these steps to refill your compressor with the correct amount of oil:
- Remove the compressor from the vehicle. …
- Clean out the old fluid. …
- Add new oil. …
- Reattach the compressor to the vehicle. …
- Cycle the belts on the compressor to ensure the oil cycles properly.
Does r134 have oil in it?
R12 systems used mineral oil, but unfortunately mineral oil doesn’t dissolve in R134a. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil.
What happens if you add too much PAG oil?
If you add too much oil to the system, it may pool in various places of the system and can coat the inner walls of the evaporator and condenser coils. This will diminish their ability to absorb or dissipate heat, thereby bringing down the overall cooling performance.
Do I need to add oil when adding R134a?
R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.
How long should you evacuate an AC system?
The time allowed for decay depends upon the size of the system, but generally, 10 minutes minimum with 1 minute added per ton is a good guideline. The moral of the story is this: A proper evacuation may take 15 minutes, 15 hours, or 15 days, it simply takes what it takes.
Do I need to add oil after replacing condenser?
When replacing a part like the condenser it is a good idea to add some extra oil with the new refrigerant. Most refrigerants do have some oil in them which should be enough. The majority of the oil in the system stays in the compressor so you should not have any issues if you do not add any more.
Does 134a have oil in it?
So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. Note that there is another kind of oil called Polyol Ester Oil (POE). The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.
