When your air-con system isn’t performing because it ought to, it is very important troubleshoot the problem and decide the trigger. One potential problem might be a scarcity of oil within the compressor. Oil is crucial for lubricating the transferring components of the compressor, and with out it, the compressor can rapidly seize up and fail. Including oil to the air-con compressor is a comparatively easy activity that may be accomplished in a couple of minutes. Nonetheless, it is very important observe the producer’s directions rigorously to keep away from damaging the compressor.
Earlier than you start, you will have to assemble a couple of provides. You will want a can of air-con oil, a funnel, and a wrench. You may additionally wish to put on gloves to guard your arms from the oil. Upon getting gathered your provides, you’ll be able to start the method of including oil to the air-con compressor. First, find the compressor. The compressor is often situated on the skin of the home, close to the condenser unit. Upon getting situated the compressor, you will have to seek out the oil fill port. The oil fill port is often situated on the aspect of the compressor. Upon getting discovered the oil fill port, you’ll be able to insert the funnel into the port and start including oil.
Add oil to the compressor till the oil degree reaches the sight glass. The sight glass is a small window on the aspect of the compressor that lets you see the oil degree. As soon as the oil degree reaches the sight glass, you’ll be able to cease including oil. You should definitely tighten the oil fill port cap securely after you might have added oil to the compressor. For those who overfill the compressor with oil, it will probably trigger the compressor to leak or fail. Upon getting added oil to the compressor, you’ll be able to activate the air-con system and examine to see whether it is working correctly.
Figuring out the Compressor
To find the air-con compressor, start by figuring out the outside unit of the air conditioner, usually positioned on a concrete pad or on a stand. It’s often a steel box-shaped unit with a fan seen on one aspect and numerous pipes and wires linked to it. Upon getting situated the outside unit, observe these steps:
- Entry the Inside:Find and take away the entry panel, often secured by screws or bolts. This panel supplies entry to the compressor and different inner parts.
- Determine the Compressor:Throughout the outside unit, seek for a cylindrical or box-shaped part with a big spherical object (the compressor head) connected to it. The compressor head is the place the refrigerant gasoline is compressed.
- Test the Label:The compressor will usually have a label or nameplate connected to it. Check with the label to substantiate that it’s certainly the compressor. Moreover, the label might present details about the kind of refrigerant used and different specs.

It’s essential to make use of the right kind of oil to your compressor, as utilizing the mistaken oil can result in untimely put on and injury to the compressor.
Evacuating the System
Evacuating the system is an important step in including oil to an air-con compressor. This course of includes eradicating all air and moisture from the system to create a vacuum. This vacuum will enable the brand new oil to be correctly distributed all through the system.
To evacuate the system, you will have a vacuum pump and a manifold gauge set. Join the vacuum pump to the service port on the compressor and switch it on. The manifold gauge set will present you the vacuum degree within the system.
Permit the vacuum pump to run for half-hour to 1 hour, or till the vacuum degree reaches 29 inches of mercury (Hg). As soon as the vacuum degree has been reached, flip off the vacuum pump and shut the service port valve.
Figuring out the Oil Kind
Earlier than including oil to the compressor, it is very important determine the kind of oil that’s required. The oil kind can be specified within the producer’s directions for the compressor.
The commonest kinds of oil utilized in air-con compressors are mineral oil, artificial oil, and polyolester oil. Mineral oil is the least costly kind of oil, however it isn’t as sturdy as artificial oil or polyolester oil.
Artificial oil is dearer than mineral oil, however it’s extra sturdy and has an extended lifespan. Polyolester oil is the most costly kind of oil, however additionally it is probably the most sturdy and has the longest lifespan.
Calculating the Quantity of Oil
The quantity of oil that must be added to the compressor will rely on the scale of the compressor. The producer’s directions will specify the quantity of oil that’s required.

4. Cleaning soap Bubble Check
Combine dish cleaning soap with water to create a soapy answer. Apply the answer to potential leak factors utilizing a brush or spray bottle. If bubbles kind and persist, there’s doubtless a leak.
5. Stress Check
Join a vacuum pump to the system and evacuate the refrigerant. Shut the valves and monitor the strain gauge for a number of hours. A drop in strain signifies a leak.
6. Nitrogen Check
Inject nitrogen into the system and pressurize it to round 300 psi. Pay attention for any hissing sounds or use an digital leak detector to detect leaks.
7. UV Dye Inspection
Add a fluorescent dye to the refrigerant and run the system for a number of hours. Examine the parts with a UV gentle to determine any leaks the place the dye has amassed.
8. Infrared Digicam Inspection
Use an infrared digicam to scan the system whereas it’s working. Warmth or chilly spots might point out a refrigerant leak, because the refrigerant expands and contracts at totally different charges than the encompassing air.
9. Stress Drop Check
Run the system for a brief interval and observe the excessive and low strain readings. A major distinction in strain might point out a leak.
Operating the Compressor
Earlier than you add oil to the compressor, it is necessary to run the compressor for a couple of minutes to flow into the present oil and guarantee correct lubrication. This is find out how to do it:
- Flip off the facility to the air-con system.
- Find the compressor and disconnect the facility leads.
- Join a jumper wire between the “C” and “R” terminals on the compressor.
- Activate the facility to the system.
- The compressor will begin working, circulating the oil.
- After a couple of minutes, flip off the facility and disconnect the jumper wire.
- Reconnect the facility results in the compressor.
- Activate the facility to the system and check the operation of the air conditioner.
- Monitor the oil degree within the sight glass and add oil as obligatory.
**Word:** For those who would not have a sight glass, you’ll be able to examine the oil degree by inserting a dipstick into the oil fill port. The oil degree must be between the “min” and “max” marks on the dipstick.
| Oil Kind | Viscosity | Quantity |
|---|---|---|
| POE (polyolester) | 32 cSt | 6-8 oz. |
| PAO (polyalphaolefin) | 46 cSt | 8-10 oz. |
| Mineral oil | 100 cSt | 10-12 oz. |
