A compressor is a vital area of the operation of the car's ac system. It compresses the refrigerant (also known as Freon) to heat up, which is then transferred through the condenser, producing cool air. How to exchange AC compressor if this doesn't work anymore? Could it be an elaborate process demanding the involvement of a professional mechanic? Let's get the answers.
Functions of an AC Compressor
A working compressor is essential if you want the vehicle AC to blow cold air. The compressor works like a pump. A belt that is connected to the engine drives this compressor.
This component allures Freon from the evaporator, compresses the coolant gas, and then sends it with the condenser.
Malfunctioning AC Compressor Symptoms
Before knowing how to replace AC compressor, you should know if it even needs the service. How do you know the component is giving troubles?
These are the warnings signs to be aware of:
- AC blowing hot air
- AC isn't cold enough
- Intermittent cooling
- Refrigerant is leaking
- Strong smell of coolant gas
- Loud noises in the compressor
- Compressor bearing failure
- AC system is not turning on
Any of these signs may suggest an issue with the compressor. After diagnosis, if you are completely sure that the said component is malfunctioning, proceed to the following segment to understand how to take it off and install a new one.
How to exchange AC Compressor: Preparation and Process
Replacing the car AC compressor is not super complicated. But you have to have some mechanical knowledge to travel through the procedure.
Things to complete Prior to the Replacement
Before starting the process, you should familiarize yourself with the environment conditioning unit and also the functions of their various parts. In addition, performing these things will make sure an even changing and re-installation process.
Flush the condenser. This will remove debris from this component together with any contaminated compressor oil.
Remove just as much contaminated oil as possible. Also, the compressor oil should not have any moisture. The accumulator in the AC unit accounts for drying from the moisture trapped in to the system. Additionally, it stores liquids like coolant and compressor oil and filters unwanted particles.
The hose assemblies are the other components that you have to clean. There are three hoses you need to remove from their connecting parts after which flush to get rid of oil and debris.
Performing a system flush is the greatest means of cleaning the AC unit's internal parts. It'll clean from the last traces of all debris and contaminants. However, do not ever flush the compressor itself.

How to Replace AC Compressor: The Process
Compressor replacement is an expensive job. The average cost of the whole process, such as the cost of a new compressor and labor costs could be from $700 to $1,000.
So, before tossing the old one, come with an experienced mechanic view it to ascertain if a repair can be done. Otherwise, adopt these measures to take the old compressor off and install a brand new one.
Step #1
The very first thing you have to do is loosening the belt before removing the lines attached to the compressor. There are some bolts that keep your compressor mounted towards the AC system. Take them off too.
Step #2
The next thing is to detach the compressor from the slot. Be careful since the attached line is thin and can be frayed easily. There can be fluids appearing out of the lines. Remember to wear gloves since these fluids can hurt the skin.
Step #3
This stage involves taking the preparation for setting up the brand new compressor within the air conditioner. The new one has to have the same configuration because the old unit. The intake and exhaust sides have refrigerant ports. The dimensions of these ports and also the check belt pulley need to be the same.
How to replace AC compressor easily? Using the products from the old component will make the process easier. Add oil towards the joints for proper lubrication.
This may be the stage in which you have to switch the old O rings and install the new ones. These rings seal our prime and low side lines towards the compressor housing. They fade away over time because of pressure as well as heat.
Step #4
This may be the step where you will install the new compressor. Place the compressor to the engine bay and fasten the products to help keep it connected to the engine block. Install the refrigerant lines by taking out the port dust covers. Fix them with products but not too tightly.
After affixing all of the bolts, it is time to reconnect the electrical connector towards the refrigerant control valve or even the engagement coil. Also, re-install the alternator and the serpentine belt.
Lastly, finish the procedure by mounting all the removed tubes and hoses together with tightening all screws, brackets, and bolts.
