As every user of the ac system, you must ensure that you have enough oil in your ac system. It is essential because the ac system will work properly as expected. It will allow the cooling system to achieve better optimal cooling conditions.
The correct amount of the oil in the ac system will ensure that all other parts of the compressor are lubricated and will help ensure that the rubber seals are protected. This will help ensure that there is no refrigerant leakage, but some vital view roles are essential.
Therefore, to be safe when using the ac cooling system, you must keep an eye on the oil overcharge. It is essential because you may have added excessive oil into the cooling system by mistake when working with the system if you are not familiar with it. The article below will discuss some precautions for using the ac cooling system and how to remove excess oil in the system.
Signs of excess oil in the ac cooling system
Below are some of the possible signs that one using the ac cooling system might encounter. Some of the symptoms may indicate that the ac system is flooded with oil.
1. Oil coming out of various parts
If, in any case, you add an excessive amount of oil into the ac system than the recommended amount in the system, the excess fat could spill out from a couple of parts of the system. It can also coat the condenser coils and the walls of the evaporator. Check Amazon for the best condenser coils
The issue could raise so many problems that will affect the overall performance of the entire cooling system. It diminishes its ability to absorb and dissipate, making you experience some downtown in the overall cooling performance.
This is one of the most common and straightforward signs that your ac cooling system has excess oil; therefore, you should check around the system and see if the oil has collected in some strange places.
2. When there is high AC pressure
Sometimes, there might be hidden excess oil in the AC cooling system that can cause surplus pressure inside the system. Though the elevated Ac pressure means that the airflow in the condenser is set to be zero, this also may be caused by a broken condenser fan of the motor. It can be a problem that can cause the issues to occur, but you can not only rule out that the possibility of the problem is an oil glut being a source of the problem.
Therefore solve and identify the problem earlier. You should start by testing the condenser fan motor and ensure that you clear any dust particles and other unwanted material inside your condenser unit before concluding the problem.
3. Not sufficient cooling
One of the most common indications that the oil in the ac cooling system is overfilled is when there is inefficient cooling in the system. When there is some internal coating inside the cooling system, it leads to reduced heat transfer.
The first sign for this is that you will start to notice that the time of cooling things is more than usual and therefore the windows will stop deforming correctly as expected.
You can now assume that everything is working well as expected, but that is not the case since the condenser fan is working fine and there is enough refrigerant in the system, but the air trapped in the air is the factor that leads to low pressure in the cooling system.
The vital tip that needs to be taken here is to ensure that the oil-saturated inside the system must be corrected before taking any action so that problems such as this are not faced when using the AC cooling system.
The good thing that you need to follow is to ensure that any surplus or excess lubricant in the system is restored to the optimum level to experience the best performance of your cooling system. The steps below will help and guide you to remove or reduce excess oil in the AC cooling system.
Steps on how to safely remove excess oil from AC cooling system
It is critical and necessary that you remove any extra oil in the AC system that is saturated to avoid any problems when using the cooling system.
Therefore, some proper methods can help one to drain excess oil in the cooling system so that you can leave the required amount needed. But you should have to start from scratch so that you can correct the mistake.
| Technique | Function | Essential product |
| Dismantle and flush the system | To remove air trapped in the system | |
| Drain out the compressor | To ensure that the compressor is drained | Check Amazon for the best compressors |
| Fill the system with the correct amount of oil needed | To provide enough oil needed by the system | |
| Recharge the system | To ensure the system is fed with what it needs |
Step 1: Dismantle and flush the system
The first evacuation is removing the air and moisture trapped inside the system. Therefore, it is recommended that you take parts of the system and then flush the parts and components that are permitted with oil to remove the excess fat. You use some quality flush chemicals, and you can combine them with compressed air to flush the different parts of the system.
Step 2: Drain out the compressor
After flushing the system, the next step is to ensure that you drain out the compressor, and it is not a strenuous exercise at all. You do this by simply putting the system upside down, possibly on a table or any clean surface and ensuring that you place a rag underneath the cooling system for some time so that all the excess oil is out of the compressor.
Finally, ensure that you recover the refrigerant during the entire process for some environmental factors. Check Amazon for the best compressors
Step 3: Fill the system with the correct amount of oil needed
After draining and cleaning the system, ensure that now you follow the manufacturer’s instructions so that you add the recommended amount of oil required. You can find special containers that will help you add the correct quantity or amount of oil into the system.
Tip: to avoid some future problems and issues with the AC components, ensure that you use the lubricants that will properly mix with your particular cooling system’s refrigerant without any problem.
Step 4: Recharge the system
Here is the final stage in that you have to recharge the entire cooling system so that you can see if it is running as expected.
Factors that determine the amount of oil that you have to add to your compressor
There are so many factors that you have to rely on when you are adding to filling the AC compressor with the
- The number of tags inside the compressor
This factor should be the first issue that you must address first. It explicitly indicates the actual amount of oil you have to add to your system before proceeding.
- Check on the manufacturers; website
It is applicable when you don’t know how to use the AC cooling system and the amount of oil you must add. You now look for the manufacturer’s instructions and guides on their website so that it can guide your model reference. You can also check the blog sections to see if you can sometimes get ideas out of them.
- Measure the oil manually
Here is where you can measure the oil you drain out of the AC cooling system to refill it with the exact amount of fat you have drained.
You will note the following when you have measured; this will be straightforward guesswork that you are only required to add the same amount of oil you have drained.
Tip: you should know at the back of your mind that some compressors nowadays come with pre-filled oil, and therefore you must drain the necessary amount of oil before installing the entire system.
Frequently asked questions:
- When there is too much oil in the AC cooling, does it cause high AC pressure?
Excess oil in the coolant system will cause higher pressure in the ac pressure readings; therefore, the answer to this question is yes. Although the extra fat is not the only issue that will lead to excessive pressure, there are other culprits, such as the debris close to the fan and the faulty condenser fan motor.
Therefore, you should ensure that you check these, jumping to the conclusion that the system is oil-logged.
- Is evacuating the Ac system removing the oil?
I have already mentioned above that evacuation only will occur and be successful when removing both air and moisture but not oil.
Therefore you must start from scratch when you want to remove the oil and refill it with the correct amount of oil needed.
Conclusion
In conclusion, any oil overcharge or excess will trigger and cause some other severe problems in the overall performance of the ac cooling system. The system’s excess oil can lead to severe issues such as premature compressor failure and sometimes inadequate cooling.
Therefore, any user of the ac cooling system should be able to monitor the oil level, so such problems will not affect you and your plan. Too much oil in your cooling system can cause some severe issues.
