Press Release

Many vehicle models have a history of AC compressor failure. Here's how to identify a faulty AC compressor.
You can understand the value of having a working A/C system in your car no matter what country you live in.
Unfortunately, because the AC system has so many distinct components, many of them could malfunction. It is sometimes advisable to not self-diagnose and go online, look for car garages in Reading and let the experts handle the proper examination and repair or replace any defective parts.
When your air conditioner stops delivering cool air, how can you know if the compressor is to blame? Learn right now! Let's first quickly review the cautions.
The most typical indications of a malfunctioning AC compressor are temperature changes or hot air. You might also hear odd noises coming from the AC compressor if you open the bonnet. On occasion, refrigerant leaks near the compressor can also be seen. If so, search online for vehicle service near me garages to locate a qualified mechanic who can identify the issue.
An expanded list of the most typical signs of a failing AC compressor is provided below:
1. Warm Air from The AC System - It could appear that this should be the list's initial option. But if your air conditioner suddenly stops working, there are a few things to watch out for that could indicate a broken compressor is to blame. If your car tells you that the air conditioner should be on, but you don't sense a temperature change, the problem may be with the compressor. To find and schedule a technician to diagnose and repair the problem with your vehicle, search online for garages in Reading.Checking your A/C compressor's power feed is a good technique to see if the problem is with your compressor. On the outside of the body of the compressor is typically where the 2-pin connector is located. You ought to have a live feed going to the pump when the car is driving, and the air conditioner is turned on. If your compressor has the proper feeds yet isn't operating, this could indicate a broken air conditioner compressor.
2. Noise from AC Compressor - As is to be expected, the internal components of the pump are working exceptionally hard to meet demand when the compressor clutch is engaged. After the bearings and other metal parts inside the compressor start to degrade and become noisy, you'll often start to hear a harsh grinding sound coming from the engine. You may determine if the noise is coming from your compressor by turning on and off your air conditioner and listening for changes in the grinding sound. The noise ought to stop when the pump is switched off, indicating that your compressor's internal components need to be changed because they are worn out. Go online and complete a MOT history checker to establish previous reasons for MOT test failures.
3. Compressor Clutch Not Moving - The majority of ac compressor pulleys have two components, which is why the compressor clutch is not moving. The engine will always spin the inner pulley without rotating the axle into the compressor. This pulley also includes an outside clutch that engages when the AC compressor should turn on. This clutch won't engage and turn the compressor axle if it has failed. It must be properly diagnosed because the compressor may also experience this if there is no electrical power.But rather than a faulty AC compressor, this is more of an indication of a defective AC compressor clutch. However, you frequently need to repair the compressor if the ac compressor clutch is damaged. Most modern vehicles have variable AC compressors, which spin continuously and do not have this clutch.
4. Engine Bay Burning Rubber Smell - If you notice an engine bay burning rubber smell when you try to switch on the air conditioning, it may indicate that the AC compressor is seized and that the drive belt also known as the auxiliary belt will not spin on the compressor pulley. However, if you have been observing it for a while, there is probably something else wrong with your car. This will make the drive belt snap off pretty soon.
5. Auxiliary Drive Belt Excessively Wearing - If you recently had to replace your auxiliary drive belt and observed that the new one is wearing out quickly or is creating a screeching noise, it could be worthwhile inspecting the pulley on your air conditioner compressor. The pulley on your compressor may develop excessive bearing movement as it ages and run at different angles due to the pulley's bearings. This motion frequently results in clutching and pulling of the rubber auxiliary drive belt, which hastens the belt's premature wear. Or the excessive movement may cause the rubber belt to scrape against the misaligned pulley, emitting a high-pitched screech.Remove the auxiliary drive belt from the air conditioning compressor and examine the pulley physically to see if there is any excessive play before concluding that it is your fault. Sadly, this is rarely the case, and replacing a worn pulley will frequently necessitate replacing the compressor itself. Some compressors allow their pulleys to be changed without having to replace the entire device.
6. Refrigerant Leak - The air conditioning system in your car features sensors that can measure how much refrigerant is present in the piping. Your lower pressure switch will recognise a leak on one of these pipes in your car and turn off the compressor to prevent damage from the refrigerant running out. Due to the components being out of reach, it can frequently be challenging to locate a refrigerant leak on a vehicle. But if you're looking for a leak, the compressor body itself is a decent place to start.Due to an intrinsic flaw, the compressor may start to over compress the refrigerant, which can lead to an excessive build-up of heat and pressure inside the compressor's body and the eventual rupture of its seals. causing your A/C to stop working by releasing its refrigerant.
What an AC Compressor Does
The compressor for your car's air conditioning is actually the system's heartbeat. It functions like a little compressor and is often powered by your auxiliary drive belt. The pulley on your A/C compressor receives power from your crankshaft as your engine rotates over through the auxiliary drive belt.
Your A/C compressor has a clutch built into the pulley since not everyone uses their air conditioning exclusively when driving. As you turn your air conditioning on and off, this clutch will engage and disengage the compressor. Therefore, the compressor pulley will turn even if your air conditioner is off without turning the compressor's internal components.
The purpose of the air conditioner compressor is to increase the temperature and pressure of the refrigerant in the system when cooling. In order to release the heat that it has absorbed from your evaporator as it reaches your car's condenser, gas-based refrigerants are packed closely together.
Location of the AC Compressor
On the auxiliary drive belt, your air conditioner's compressor will typically be somewhere. Two refrigerant pipes will be attached to its body, and an electrical connector will supply power.
You can normally find the AC compressors around the bottom of the engine, below the alternator and power steering pump, so you can go underneath your car to find it.
