Why is my AC Broken?

AC broken driving while your AC is broken, when heavily relying on your car, can quickly become a nightmare. Having to take the kids to school, run errands, and drive to work with windows rolled down can make things uncomfortable fast.

No matter the time of the year, if your car aircon system decides to stop working, it can make travelling in the car unbearable.

Are you worried the auto mechanic or auto electrician are just making up problems while trying to take advantage of you, and quoting you the highest possible price for parts that may not even need replacing when your AC Broken?

Perhaps you are too busy to do adequate research into the problem?

We will discuss the most likely reasons your AC Broken, helping you understand the issue so you can stay cool and get it fixed as soon as possible.

There are many different causes of a AC broken, which include the following:

Electrical Issues
Failed compressor
Low or no refrigerant
Foul or clogged system
Ventilation system

If it sounds like I’m speaking a foreign language, no need to worry.

Unless you’re passionate about cars or work as an auto mechanic, you likely wouldn’t know what these issues are or why they might be causing your AC Broken system.

Let’s break them down, and take a look at each more closely.

Failed Compressor

One of the most common causes of a AC broken is that the compressor has failed. Wait, what exactly is a compressor? Think of a compressor as the heart of your car’s air conditioning system, as it pumps it produces cool air. If it can’t beat anymore, then the system work properly.

Why did the compressor fail?

Wear and Tear – A compressor in your AC Broken system can fail due to general wear and tear accumulated over many years and thousands of kilometres.

Oil – Another cause may be that there is not enough oil in the system.

Debris – It’s also possible there is debris in the air conditioning system.

How to check for a failed compressor?

So, how do you check if the compressor is why your AC Broken? You need to measure the pressure rise across the compressor. If the pressure is lower than normal, it’s a clear sign the compressor has failed or is close to failing.

If it’s a failed compressor, you simply need to get the compressor replaced, and you will have your car AC system working again in next to no time!

How to fix it?

If it’s found that the refrigerant level is low, the best fix for your AC Broken system is to add more refrigerant to restore proper function. They’ll also seal any leaks to prevent future refrigerant loss.

Ventilation System

A problem with the ventilation system can be one of the most misleading and confusing causes of a AC broken.

But why? The ventilation system has a blower, which moves air through a series of ducts and directs it through different passages depending on the vent chosen and the temperature setting.

What Causes a Ventilation problem?

If the ducts end up clogged, or the ventilation doors break they can no longer direct the ventilation air, which can cause the cool air to become warm.

This makes it seem as though you have a problem with a malfunctioning car aircon system even though the AC broken is still working perfectly.

How to check the Ventilation System

To check if it’s a ventilation problem instead of an AC Broken issue, you can check the feed line to your evaporator. Does it feel cold under the car hood, even though there is warm air blowing into the car from the vents?

If this is the case, then it is a ventilation problem, and replacing the damaged ventilation components will fix the problem.

Foul or clogged system

Another possible problem leading to a AC broken is caused by fouling or clogging your system. Uh, say what?

Using low-quality leak stop agents may be the cause. Or if your AC system has recently been opened, debris may have gotten into the system doing damage.

If the AC Broken system is clogged, it will cause pressure changes in the wrong sections and reduce the cooling efficiency of the AC.

How to check for clogs

To check for clogs, a mechanic will inspect the pressures around the system, and look for any abnormalities. If they discover a component is clogged, then it’s advisable to replace that component.

Leaking Refrigerant

Perhaps the most common cause of an AC Broken system is a leak, which can cause the refrigerant level to drop or, worse, become completely empty.

What Causes Leaks?

Due to the nature of refrigerant used in a car air conditioning system, it is highly common that leaks occur, which is amplified by the operating environment the system is exposed to.

How to check for leaks?

To check for a refrigerant leak in your AC Broken system, they will measure the low-side pressure. If the pressure is lower than normal, it’s highly likely there’s a leak causing the low refrigerant level.

Electrical Issues

There are countless electrical issues that may be the cause of your AC Broken or malfunctioning, such as:

– If the ventilation system does not give the compressor the signal to turn on, then the air conditioning won’t cool the vehicle.

– The electric fan cooling your condenser has blown a fuse, burnt out, or has a bad relay, which will result in the car aircon system malfunctioning at low speeds.

– One of the sensors in the AC Broken system may fail, causing incorrect readings and preventing the system from working properly.

Following these tips and regularly having your AC Broken system inspected for potential issues can help prevent future problems, ensuring a reliable car you can trust. Enjoy time with your family and loved ones without worrying if your car will endure a hot summer journey.
