Steps for an AC Compressor Oil Change
The steps below will guide you through the AC compressor oil change process.
Step 1: Turn Off Power
It is crucial to turn off the electrical power to your AC unit before you start working on it. Locate your circuit breaker and switch off the power to avoid any electric shock or injury.
Step 2: Locate the Compressor
The compressor is usually located in the outdoor unit of your air conditioning system. You’ll need to use a screwdriver to open the access panel. The compressor typically looks like a large black or metallic cylinder.
Step 3: Drain Old Oil
Draining the old oil is a critical step in the AC compressor oil change process. This action removes the old, degraded lubricant, which may contain contaminants, from the system. Here’s how to go about it:
Locate the Drain Plug: The drain plug is usually found at the bottom of the compressor. This plug is what keeps the oil in the compressor. You may need to remove a cap or covering to access it.
Place an Oil Drain Pan: Put an oil drain pan under the compressor, making sure it’s large enough to hold the amount of oil that will be drained. This will catch the old oil as it comes out, preventing spills.
Unscrew the Drain Plug: Using the appropriate size wrench, gently unscrew the drain plug. Remember to wear gloves to protect your hands from the old oil.
Drain the Oil: Once the plug is removed, the old oil will start to flow into the drain pan. It’s crucial to let all the old oil drain out to ensure that the new oil doesn’t mix with it.
Dispose of Old Oil Properly: Once draining is complete, safely dispose of the old oil according to local regulations, as it can be harmful to the environment.

Step 4: Add New Oil
Adding new oil to the compressor replenishes the lubrication system, ensuring smooth and efficient operation. The steps are as follows:
Select the Right Oil: Check the manufacturer’s specifications for the type of oil compatible with your compressor. Using the wrong type can lead to operational issues.
Measure the Amount: Also, based on the manufacturer’s guidelines, measure the amount of oil needed. Typically, this information can be found in your AC unit’s manual.
Use a Funnel: Insert a funnel into the hole where the drain plug was removed. This will help you pour the oil cleanly, minimizing spills.
Pour the Oil: Slowly pour the new oil into the compressor. Make sure to follow the manufacturer’s guidelines on the quantity. Overfilling or underfilling can cause problems.
Step 5: Seal and Test
This final step ensures that the oil stays in the compressor and verifies that the system operates correctly with the new oil. Here are the specific actions you need to take:
Reattach the Drain Plug: Put the drain plug back into the hole at the bottom of the compressor. Use a wrench to tighten it, making sure it’s secure to prevent leaks.
Close the Access Panel: Once the plug is in place, close the access panel on your outdoor AC unit. Use a screwdriver to fasten any screws you had removed earlier.
Restore Power: Turn the power supply back on by switching on the circuit breaker.
Test the AC Unit: Finally, turn on your AC to circulate the new oil and ensure that everything is working correctly. Listen for any unusual sounds and monitor the system for any signs of oil leakage.
