The Functions Of An Air Conditioner In Vehicles

Air conditioning in a car is an absolute necessity, especially when you’re on a long drive during those hot summer days. Not only does it provide the people in the vehicle with the right amount of air, it also stops you from having the window opened and inhaling the fumes from the cars around you.

You may be wondering how the cooling unit in your car works, or up until clicking on this article, may have never thought about it. Cooling systems were first placed in cars in 1939, and since then, most vehicles are fitted with one.




Automotive air conditioners are made-up of four parts. The compressor is the core of your air conditioning unit, it takes the refrigerant gas and pressurises it, making it nice and cool.

The condenser is at the front of the car and is like a radiator, as the compressed warm air passes through the condenser, it gets cooler. The evaporator does the opposite job, as the cool liquid passes through the tubes; air is pushed through and gets cold. As soon as it warms up, it then turns back into a gas.




The thermal expansion valve controls the flow, allowing you to decide on how much or how little air you want to be coming out of the valves.

Maintaining your cooling unit and ensuring that it’s functioning to its full capacity is important, especially throughout those warmer days.

Why You Must Get Your Car Checked

Owning a car comes with not only a large amount of responsibility while on the roads, but also ensuring that your car is maintained and receiving the right amount of care. While the amount of services required for your vehicle depends on the manufacturer, on average it’s recommended that you allow for a mechanic to check it every 12 months.

As a car owner, to ensure that your vehicle continues to provide a form of transport, taking you from A to B, the best thing you can do is to know your car. One of the worst things you can do is to avoid getting your car maintained, and fixed when necessary. Prolonging repairing a part of your vehicle can cause more damage, as well as increase your mechanical bill.

Just like eating healthy foods is good for your body, up keeping your car is important. There are some simple ways to see if a mechanical check is needed for your car.



In between getting your car serviced, there are some tasks that you can do that will allow you to see if there are any obvious issues that need to be immediate attention. Turn your vehicle on, check that the lights are all working, see if the tyres are pumped up and listen out for any abnormal noises that may be coming from your car.

Unless you’re a qualified mechanic, we suggest that you leave the job to an expert, who has a large amount of experience in handling vehicles of all types, as trying to fix something you have no idea about can cause major damage and can put your well being in danger. Depending on how often you use your car and the type of roads you drive on, having your tyres functioning properly is very important.



It can be dangerous when driving in wet conditions, which is why all drivers must take extra care on the roads. The air pressure of your tyres should be checked at least once a month, to ensure that it’s at the right number. If the pressure is incredibly low, than you must go to the nearest petrol station to pump up the tyres, if it continues to decrease, there could be a hole and needs to be looked at by someone in the mechanical industry.

If you feel that there is some part of your vehicle that requires an examination by a professional, make an appointment to see your local mechanic.
