  • Turn off the power to the compressor unit and disconnect the wires from the terminals
  • Remove any bolts or screws holding the compressor unit in place and pull it out of the engine compartment
  • Place a drain pan under the discharge line fitting on the compressor and remove the cap or plug from this fitting
  • Allow all of the refrigerant oil and Freon gas to drain out of the system before proceeding
  • Reattach the discharge line fitting and add fresh refrigerant oil to the system through this fitting until it starts to drip out ofthe overflow valve located on top ofthe compressor unit

How Do You Drain Refrigerant from Ac Compressor?

When your AC compressor breaks down, you’ll need to know how to drain the refrigerant. Otherwise, you’ll end up with a big mess on your hands. Here’s a step-by-step guide on how to do it:

1. First, turn off the power to the AC unit. You don’t want to be working with live electrical wires. 2. Next, locate the AC compressor.

It will be a small, cylindrical object located near the front of the AC unit. 3. Once you’ve found the compressor, look for the refrigerant lines coming out of it. There will be two lines – one for the suction side and one for the discharge side.

4. Using a wrench or pliers, loosen the bolts that are holding these lines in place. Be careful not to damage them as they can be expensive to replace.

5. Once you’ve loosened the bolts, carefully remove the lines from their respective fittings on the compressor (one line will go into each fitting).

Make sure that you cap or plug these fittings immediately so that no dirt or debris gets into them. 6 At this point, all of the refrigerant should have drained out of the system and into a container placed beneath it (this is why it’s important to have someone help you with this project).

How Do You Drain Water from a Compressor?

Assuming you are talking about an air compressor: Most air compressors have a built in drain valve near the bottom of the unit that can be opened to allow water to drain out. If your model doesn’t have one, you can use a garden hose to siphon water out of the tank.

Just open the release valve and hold the hose end inside the tank until it’s full, then place the other end in a bucket or sink and let gravity do its job.

How Do You Remove Oil from a Compressor?

If your compressor has an oil level sight glass, check the oil level and add oil if necessary. If your compressor does not have an oil level sight glass, do not add oil. To remove oil from a compressor:

1) Place a drain pan under the discharge line of the compressor. 2) Open the discharge valve to allow the compressor to drain into the pan. 3) Close the discharge valve when the pan is full.

4) Remove the drain pan and dispose of the used oil properly.

What Happens If You Don’T Drain Air Compressor?

If you don’t drain the air compressor, the compressed air will eventually become contaminated with water. This can cause rust and corrosion inside the compressor, which can lead to premature failure. Additionally, if moisture-laden compressed air is used for applications such as painting or sandblasting, it can ruin the finish or cause other problems.

How to Drain Ac Compressor on Car

If your car’s air conditioner isn’t working properly, one potential issue could be that the compressor is low on refrigerant. To check this, you’ll need to drain the compressor. Here’s how:

1. Park your car in a safe place and turn off the engine. Make sure the area around your car is well-ventilated before you begin working. 2. Locate the Schrader valve on your car’s AC compressor.

This is usually located near the front of the engine compartment, on top of or next to the compressor itself. 3. Use a wrench to loosen the cap on the Schrader valve, then press down on the valve to release any pressure that may be inside the system. 4. Place a catch pan under the compressor so that any fluid that drains out will be caught and can be disposed of properly.

5. Slowly open up the drain cock (or petcock) located at the bottom of the compressor housing until all of the fluid has drained out into your catch pan. Be sure to keep an eye on your catch pan so it doesn’t overflow!


If your car’s AC isn’t working properly, it may be because the compressor needs to be drained. Draining the compressor is a simple process that can be done at home with a few tools. First, you’ll need to find the AC drain valve, which is usually located near the bottom of the compressor.

Once you’ve found the valve, open it and allow any water or condensation to drain out. After the compressor has been drained, close the valve and restart your car’s AC system.
