Diagnosing the air conditioning in your car

Summers or winters, rains or mist the air conditioning of your vehicle keeps you comfortable and relaxed. All its asks in return is for you to ensure that you take care of its maintenance and not let it down whenever it catches a cold. Well, when I say to catch a cold what I mean is when it develops a problem. Many of us will keep the air-con running in our vehicles even when it shows signs of breaking down or has broken down. What we, however, do not do is pop open the hood, take a peek at the air-con systems and look for ourselves what might have gone wrong. There may be many reasons why you do it, for me, there was the simple question of thwarting my ignorance and researching to find out how to check for problems in the air conditioning of a vehicle.

You though are in luck as I am going to share my findings with you.

Let us look at how you can diagnose issues with your car’s air-con and what can be done to fix it. If you feel this is too much there is always the option of taking your car to Air Conditioning Coventry to get fixed.

Switch the air-con on and check the following:

The airflow speed when it is at its max.

check if all the airflow vents are working. Switch the airflow between different vents to check if they are allowing airflow.

Change the temperature settings from cool to hot and back again and see if the AC can handle the changes.

Put a thermometer at the mouth of the air vent to check the temperature. This should be done when the temperature is set at max cooling to check the cooled air’s temperature.

Problems in the airflow could mean there is a problem or blockage in the vents.

If the cooling effect is low then it could spell trouble with the compressor clutch, the gaskets in the pipes or a leakage in the cooling system.

To diagnose issues in one of these systems the following steps can be followed.

Open the hood of the vehicle and check the compressor clutch for slippage. To do this, turn on the engine and the air-con. If the clutch is slipping you will be able to verify it easily.

Check under the belly of the vehicle for leaks. This should be done when the vehicle has been parked overnight or for a long time.

Another way of diagnosing leaks is by connecting a gauge to the gaskets in the cooling system and checking the pressure readings. The desired pressure is different for different vehicles so should be looked for in the owners manual beforehand.

Physically check the pipes and connectors for leaks.

It is best to check the air-con on your vehicle regularly to ensure its proper functioning. Additionally, the air-con should be inspected by a mechanic every time it is taken for regular maintenance run. This will ensure that it is running and can be cleaned up so dust and allergens don’t accumulate in the vents.

Remember the air-con not only keeps your vehicle’s cabin temperature regulated but is also essential in ensuring that the windscreen and the windows do not fog up because of temperature variations. Even if they do fog up a functioning air-con can quickly clean it up and restore visibility. If all these reasons are not enough, keep in mind that if there is a fault in the air conditioning system it can develop over time and cause further damage which may lead to a failed MOT. So keep it maintained and avoid hefty bills and fines. For your vehicle’s MOT Test visit Central Point MOT. They test and fix whatever issues might be unearthed during the test.
