A/C Maintenance and Repair

During the summer months your car’s air conditioner can be a necessity. As with all other aspects of your car, a little preventative maintenance can save you a lot of money in the long-run. Keep your car cool and increase your gas mileage with regular AC checks and maintenance services at Splendour Auto Care Center, Al Qouz, Dubai.

Car A/C - Time to get a Check Up?

Car air conditioning units are rather sensitive. They are, of course, very good in their work, which means that they are equally hard to fix. We at Splendour Auto Care Center, located at Al Qouz, Dubai would advise you to get your car A/C checked before it breaks down on a hot and sweltering day. It is not nice: take our word for it.

Things that can go wrong

With a car air conditioner, there are hundreds of things that can go wrong. But we are going to cover a few of the most common things that can go wrong.

·         Weak Airflow

A very common problem with old car air conditioners is the reduced airflow. Of course, the heat can be very distracting, but we shall ignore that aspect. The most common reason that this can happen is because of condensation forming in the pipes, preventing the air from reaching the vent. Another thing that can go wrong is in case the hose connecting it is loose. In the worst case scenario, the ventilation fans could also have stopped working.

·         Not Cool Enough

It is not cool to have a problematic A/C (pun intended). The main causes of an air conditioner which is not as effective as it used to be can be something as small as the gas leaking out to something much bigger like a failed compressor or a faulty evaporator. Of course, it can also be things like the vacuum seals leaking or a clogged expansion tube, which you can take care at your garage if you are experienced enough. But we at Splendour Auto Care have seen owners coming with A/Cs that have broken down further due to amateur efforts to fix them. Our advice is that when you see a problem with your air conditioner, take it to experts.

·         Bad Odour

A moldy odour coming from the A/C vent might be because of just that: mold. Due to missed servicing dates, evaporation cases can often accumulate water, which is a heaven for molds. Get that cleaned. While you are at it, check your air filter as well. A dirty air filter does not bode well for the cabin.

·         Leak

Air conditioner fluids can leak out. While this is not a very common problem, the effects can be very hazardous in case there is a leak in your air conditioning system. The leak can create pressure in the compressor, which will breakdown next, causing the black metal particles to get sucked into you’re A/C system, causing a chain reaction, thus taking the whole thing down.

What to Do?

While there are a few cars out there which can indicate that there is a problem with your A/C, most vehicles do not have any specific indication. This means that if you suspect something is wrong, it is best to bring it to a professional repair center unless you want to spend more money on getting it fully replaced.

How to Repair Your Own Car A/C

Repairing a car A/C is not as easy as it sounds. In fact, it is a lot harder than most of the other things that you can do by yourself in our car. Why? First off, your car air conditioning system has a LOT of different parts. This includes a lot of mechanical parts, electrical modules and connector pipes, all adjusted to function at specific temperatures and pressures. Secondly the car A/C is quite a complex machine. However, we will still go forth with this article where we have put together a DIY for fixing your car air conditioning unit.

Starting The Work

The very first thing you should do after popping up the hood for your AC repair  in Dubai is check if there is any feedback in the car A/C. By feedback, we mean checking for pressure. For this, you will need a pressure gauge.

Simply put, the pressure gauge measures the pressure in a tube. There are 2 cases which can occur here:

·         The first is that you get an indication of some pressure. This is the better alternative, since it implies that the system has not been inactive too long.

·         The alternative is a completely flat A/C unit, which has a very high probability of having moisture condensation inside the system.

An air conditioning unit with moisture, especially when it has been sitting there for a while should be immediately handled with a dryer system, because it can cause complications if not dealt with at the beginning. Next, if the system is empty, denotes a leak somewhere in the system. We need to find exactly where this is. This is the simple part. We simply need to find the valves in the A/C unit. There are 2 removable valves, corresponding to the low pressure side and the high pressure side. Once you are absolutely sure that there is no pressure in the system, open them up and get your vacuum pump.

A vacuum pump essentially works by creating a vacuum. You would need a full gauge set for doing anything related to A/C. Hook these up to the 2 valves and start it up. As soon as this starts up, if there is a leak, you will see condensation leaking out. Keep an eye out as spotting it immediately can be a little tricky.


Once you have determined the air conditioning line that is at fault, it becomes easier. You have to simply remove the said line and repair it to get it back up. However, that is easier said than done. First thing you have to do is get your wrench out. This is needed in order to unscrew the faulty pipeline. Before going any further, make sure that all the components are properly secured. Do not drop them and damage them in an attempt to fix your A/C. After it is properly unscrewed, be careful not to get any dirt or moisture in the system.


Fixing the delivery system is done via the good old soldering. Note that an amateur soldering would not hold the line very well, and in case of a big enough leak, a soldering would not even work properly. However, once that is done, what you need to do is check if it works. Get your vacuum pump out again, and connect the system to the pump and turn it on. Leave it for a little while (around 30 minutes) to make sure that if there is any moisture in there, it would boil away. Once that is done, simply close both valves. If the pressure holds, you know you are successful. Otherwise, there is still a leak somewhere.

Finding the Leak

Take the manifold gauge system and take the middle hose off (usually yellow in colour). What you need after this is UV dye. This is a very common thing often used to find leaks, and can be found at any shop specializing in AC repair in UAE. Pour a little of it into the hose and then use it to charge the A/C system just enough with refrigerant to work. Now comes the refrigerant. Take that, put the valve that is used to plug the refrigerant into the hose and fix it on the top of the container. Make sure the other valves in the manifold gauge are completely closed.

Once this is done, plug it into the hose and puncture the container so that the refrigerant is running. After this, turn on your car, put the A/C on vent and turn it on. Get back out, to the gauge and slowly turn the low pressure valve so that the refrigerant circulates through the whole system. As soon as you hear it get into the system, start shutting the valve off. You simply need enough to circulate the system, not enough to fill it. You will see the high pressure counter climbing at this point as well. Once this is done, shut down the refrigerant by closing the pin again and get eh car up to 200 rpm and opening the low pressure valve to suck out the rest of the refrigerant in the hose. After all is done, close it, open the hoses and shut down the car.

Last but not the least, use your UV light and shine it over the system and you can find your hidden leak. Close that up, and you just repaired your own car A/C.

Be Careful

First off, make sure to take proper care at all times while handling the car. This includes using gloves and safety goggles at all times. Next, make sure that nothing is rattling or loose while you are operating. Check for dirt at all connections, and always oil them up before reconnecting. Caps should be always on to seal in the refrigerant. While filling up the refrigerant, make sure not to come in contact with any of it. It is not a nice thing to freeze off your skin.

Finally, unless you know what you are doing, handling your car is not recommended. Opt for a professional AC repair in AL Qouz Dubai if you are in doubt.
