How To Put Oil In A/C Compressor

Summer is here, and that means it’s time to crank up the air conditioning. But before you can turn on the A/C, you need to fill up the compressor with the correct oil. Here are some tips on how to do just that: 1. Make sure your compressor is properly cooled before you start. Running an overheated compressor can damage its internals, leading to a longer repair time or even a premature failure. 2. Check your oil level frequently. Overflowing oil can cause serious engine damage, so it’s important to keep an eye on it and top off as needed. 3. Disconnect the belt if you’re not going to be working with the compressor for an extended period of time. This will prevent possible engine damage if something happens while the belt is off—for example, if there’s a power outage. 4. Use approved oil brands and make sure they’re compatible with your compressor type and model. Compressors can have different oil capacities, and using an incompatible oil can lead to damage or even a compressor failure.

What is an A/C compressor?

An AC compressor is a mechanical device that helps to circulate air in an enclosed area. The compressor works by using energy to increase the pressure and velocity of air movement. This increased airflow is necessary for cooling purposes in a building or structure.

How does an A/C compressor work?

An AC compressor works by using a rotating fan to push air through a refrigerant. This cold air is then blown into the room where it needs to be cooled, most commonly in an office or home. To do this, the compressor must first be filled with oil. This will help to keep the blades spinning smoothly and prevent them from seizing up.

How can I put oil in an A/C compressor?

One way to put oil in an A/C compressor is to pour it into the air filter. This method is risky because if the air filter becomes clogged, oil will not be able to flow and the compressor will not work. Another way to put oil in an A/C compressor is to use a dipstick. Oil should be added gradually so that the compressor doesn’t overheat.


If you’re like most people, your A/C compressor kicks in every time it gets a little too hot outside. But sometimes the oil can get clogged up and prevent the compressor from working properly. Here’s how to clear out the oil and restore air conditioning all at once:
