Your Vehicle’s AC Compressor, and How it Works.

Posted: January 25, 2012 in Welcome

Most consumers, and many mechanics think the AC Compressor makes the A/C in your vehicle cold. That’s simply not true. Although this is a common belief, the A/C Compressor actually creates heat as well as high pressure. When the A/C Refrigerant is under high pressure, it is hot. The cool effect is actually created elsewhere, and we will talk about that in just a bit.

Your A/C Compressor also has an Air Conditioning pulley, or AC Clutch. In the AC Compressor, there are two ports. One is the Suction port and the other is the Discharge Port. The Suction Port is the Inlet, and is the bigger diameter of the two. The Discharge Port is the Outlet and is the smaller port of the two. Air Conditioning Freon is suctioned into the A/C Compressor, then it is further compressed, and lastly it is discharged out of the outletport of the Compressor. Your Air Conditioning AC Compressor encases a variety of components that allow the refrigerant to enter, compress and then exit the A/C Compressor.

The A/C Clutch is at the very front of the AC Compressor, and consists of a Hub, Pulley and Coil. The Hub is at the very front part of the Compressor and is what engages physically engages the internals. The Compressor Pulley is where the belt sits, and the Coil is the electronic part that engages the hub. Once the A/C Compressor is engaged, the inside components begin to move the Freon through the A/C Refrigerant system.

Turning whenever then engine is cranked, the A/C Compressor Clutch Pulley will spin even if the AC Compressor is off. If the A/C System is turned on, power is sent to your A/C Compressor Clutch and it will then engage. However, if the pressure in the system (or the refrigerant level) is either too low or high, switches will kill power to the Compressor to keep from damaging it.

Keep in mind, most late model vehicles use the A/C system for Defrost Mode. That’s because the air conditioning system is not just for cooling, it’s also for dehumidifying.

Once your AC Compressor is engaged, it brings the lower pressure freon in, and ironically compresses it. Your refrigerant then moves into the AC Condenser. In the Condenser, refrigerant moves through the small tubes in the A/C Condenser. Air that blows through the Condenser helps to cool down the refrigerant pressure. When your vehicle is moving at higher speeds, the natural movement of the outside air does a good job at cooling the freon. When an automobile is not moving, the Fan Clutch or Cooling Fan Assemblies engage to move air through the A/C Condenser. Once the Refrigerant is cooled down, it then moves towards the Evaporator. Prior to entering the Evaporator, it must move into an Expansion Device. As the refrigerant travels through the orifice in the expansion device, it is restricted. As the refrigerant passes through this orifice, it expands very quickly, and turns to very cold liquid.

2002 Jeep Liberty AC Compressor Issues and Problems

We get calls every day, where a fine customers says something like this:

2002 Jeep Liberty AC Compressor“The A/C on our 2002 Jeep Liberty also went out. We were quoted $1900 to repair last summer. I couldn’t swallow the repair price-tag, so we toughed it out through the summer. I am also convinced that the A/C can be repaired for much less. I am researching pricing for a new compressor and condenser and how much the labor would be to replace. I imagine this might come out much less than what the dealership is telling us.”

The 2002 Jeep Liberty AC Compressor fails quite frequently. We’re not exactly sure if it’s an issue within the A/C System that causes premature failure, or if these 2002 Jeep Liberty A/C Compressors are just prone to breakage. What we do know is that we sell a bunch of them! Many times, the A/C Compressor Clutch will go out. Replacing it is an option, but the Clutch is only available through the Jeep Dealer and typically costs more than our Complete 2002 Jeep Liberty AC Compressor Assembly! Imagine that????

Moreover, swapping out the Compressor Clutch does not mean that your 2002 Jeep Liberty A/C Compressor has been replaced. In fact, if you think about it, it still has the same mileage on it as your Liberty does. These days, many AC Compressors are not lasting more than 100,000 miles (sometimes it’s quite a bit less than that).

Our Aftermarket 2002 Jeep Liberty Replacement Compressors are designed to be an exact fit and are of OEM quality. Usually under $179 (with shipping), our prices for the 2002 Jeep Liberty AC Compressor are fantastic and we still offer a full one-year warranty on the part. Please remember that when replacing the Compressor in your Jeep Liberty, it is imperative that you also install a new AC Accumulator and Expansion Device. Doing so ensures you are completing the job the right way and also maintains your warranty. For more information on why you should always replace the Accumulator or Receiver Drier and Expansion Device, visit here.

AC Receiver Drier or Accumulator

Replace that AC Receiver Drier or Accumulator!!

The Air Conditioning Receiver Drier , sometimes referred to as the Filter Drier, functions just as its name would indicate: as the filter for the refrigerant system. There will always be an Inlet Hose and there will always be an Outlet Hose and both are typically cylindrical in shape. Receiver Driers are always used on AC systems which also have an Expansion Valve. When locating your Receiver Drier , you’ll find that they look similar to a metal tube or can, and will always be found on the high-side of the refrigerant system, usually between the Expansion Valve Inlet and the Condenser Outlet. If you have a late model vehicle, your Receiver Drier will likely be built into the AC Condenser. If your Drier is made into the Condenser, it can sometimes be serviceable, although sometimes it may need to be replaced with the Condenser.

Air Conditioning Accumulators are just like Filter Driers. They are both filters. The AC Accumulator is found on the low side, whereas the Filter Drier is found on the High Side. If your system has an Accumulator, you will also need to replace the Expansion Device for the system. In this case, it will always be an Orifice Tube.

There will always be a Dessicant Bag inside of either your Accumulator or Receiver Drier . As mentioned before, the purpose of the Dessicant Bag is to filter out both moisture and debris. When you take your AC System apart, you are allowing moisture to enter the System. This moisture is very harmful to the Dessicant because it diminishes its ability to filter properly. Because of this, it is highly advisable that you always replace eithe ryour Receiver Drier or Accumulator when opening the Air Conditioning System.

Replacing your Receiver Drier or Accumulator is similar to properly doing an oil change. If you go to your local garage to get your oil changed, they always replace the filter, right? This also applies to your vehicle’s AC System. If it is necessary to remove and replace an AC Compressor or any other AC part, make sure to also replace the Accumulator or Receiver Drier. Doing so also ensures you preserve your warranty.
