Get the lowdown on your car’s air conditioning

If you live in the UK, you’ll be loving this great weather. After a long winter, the rising temperatures and sunshine are very much welcome. But one thing that you’ll suddenly notice is that your air conditioning may not be up for the job. You turn it over and are greeted by a blast of hot air. Not exactly the best way to cool down on a hot day, is it?

But the good news is that at Bryan Swales Motor Repairs, we know how to get the best out of your car’s air conditioning. Our article can keep you cool and comfortable during the spring and summer.

An Air Con Recharge – Why You Need It

Just like anything else in your car, your air conditioning system needs regular services.

Why? Well, the main reason is the loss of refrigerant. This happens because your A/C system uses rubber hoses to complement the fixed aluminium pipes. Over time, this can lead to loss of gas or what is commonly known as refrigerant.

This is essential for your air conditioning to cool you down during the warmer months of the year. Otherwise, low refrigerant will mean heat can’t be efficiently removed from the cabin.

Another problem that happens with your air conditioning is that the system will not operate where the refrigerant is too low. This can lead to component malfunction and expensive repairs. That’s why we always recommend operating your air conditioning throughout the year to keep the system ticking over.

Understanding How Your Air Conditioning Works

We love some car science. So, we thought we’d share with you how your air-con system works to cool you down. Let’s take a look at the steps:

  1. It all starts when refrigerant passes through the air-con system thanks to the compressor.
  2. This liquid refrigerant transports through the expansion valve and boils. This is where it turns into gas and the cabin air from your vehicle passes over the evaporator.
  3. During the boiling of the liquid refrigerant, the heat from your car is absorbed. Of course, this is where you need sufficient levels of refrigerant for this to work.
  4. The refrigerant gas goes into the compressor where the pressure and temperature of it rises.
  5. The refrigerant gas in your air-con system now heads to the condenser where ambient air blows thanks to the condenser fan.
  6. The heat is taken from the refrigerant and dispersed into the outside air.
  7. There you are! Your air conditioning system has now moved the heat from the cabin to the outside of the vehicle and cooled the air in the cabin as part of the process.

Is there an Air Con Check or Is It Part of the MOT?

A lot of your car is checked during an MOT. But unfortunately, this doesn’t include your air conditioning system. It’s also not standard practice for manufacturers to check the air con during a service. This means that you have to arrange an additional service for your air conditioning.

This is a service that we offer at Bryan Swales Auto Repairs. We can make sure that your air conditioning is in good condition and that it is going to keep you cool when it’s hot outside. 

We would advise you to have your A/C system checked every 12 months, and serviced every 24 months to ensure that the system remains in good condition and keeps you cool when you need it most.

The Refrigerant – Why Your Air Con Can Stop Working

Are you wondering what is the most common cause of an air conditioning system breakdown? It’s down to the refrigerant. If your car doesn’t have the right quantity in the system then it’s not going to be able to cool down the cabin.

The refrigerant leaks through a natural loss or system fault. A natural loss of refrigerant is one of the easiest problems to rectify, replacing this and can return your system to full health in many instances.

How We Can Replace Your Refrigerant

Do you want to know more about how we re-gas your vehicle? Well, we’ll take you through the steps you need to know about.

  1. A performance test is completed – we check the temperature in your cabin, as well as the ambient air.
  2. We remove the refrigerant – it’s weighed to see if it’s the correct level for your specific vehicle.
  3. A vacuum leak is completed.
  4. Pressure Leak is completed.
  5. We use a vacuum pump – this removes any moisture from your A/C system.
  6. A dye is added to your system – this can indicate future leaks.
  7. Oil is added where it’s needed.
  8. We weigh in the correct refrigerant.
  9. Finally, a performance check is performed – this makes sure your air conditioning is now working.

Don’t Forget the Air Con Service

It is recommended to get an air-con service every 24 months. This is to ensure that the other components of your air-con system are cared for, as well as a re-gas. This can make sure that the cabin stays cool and there aren’t any unpleasant odours in your vehicle. This is what’s involved with an air-con service:

  1. A/C Condenser inspection.
  2. Compressor drive belt inspection.
  3. A/C pipes under the bonnet inspected.
  4. A/C condenser cleanout for better heat exchange.
  5. Refrigerant receiver dryer or accumulator replacement.
  6. Pollen filter inspection.
  7. A/C debug treatment completed for killing bacteria.

The Way to Keep Your A/C System Healthy without Problems

A lot of car owners think that the air conditioning system is only going to be used during the warmer months of the year. Sure; this maybe when it’s used the most.

But your air conditioning system can be enjoyed all year round for dehumidifying the cabin air. You can clear misty windows that are blocking your vision. But doing this can also make sure that your air-con works at its best and stays healthy. It can keep the compressor working and keep away faults.
