Auto Air Conditioning-101 Made Easy-An Insight into your cars Air Con System

Auto Air Conditioning

Auto Air Conditioning

Of course, the air conditioners found in the car works similarly to the air conditioners used at present in the offices and houses. In simple words, the air conditioning system of a car is the smaller unit of window air conditioning systems found in many homes.

Although they come out with the same end result. So, the mechanism of a car air conditioning system is quite different from the conventional domestic air conditioning units. The car system in my opinion is a little more complicated.  The car system takes the warm air from out of the vehicles cab and recycles the air. Hence, through the cars air-con system. Returning the air to the cab as cold air.

Auto Air Conditioning-Not for DIY motorists

The system is really a heat exchange unit fitted under the cars bonnet. Therefore the air-con system can be very complicated to repair by the DIY motorist. So if you got certain problems in the car air conditioning system then you need to visit your local car service centre. Such as Pellon Tyre and Auto Centre in Halifax UK.

In order to understand, how the car air conditioning system operates. Then, it is required for you to know some of the various parts of the air-con unit. Although systems slightly differ? so In this system, there are two types of valves. There are expansion and dryer valves, which are required for the correct functioning of the air-con system. The function of expansion valves is to regulate the internal temperature of air, and it controls the refrigerant flow inside the system.

This also reminds me that air-con systems are serviced by specialized equipment. Subsequently, our operators have to attend a course and be certified for using this specialist machines that we use.

Auto Air Conditioning-Leaking gas is the main problem

In general though, if your air-con system is giving you certain problems. So, call a local garage. Off course most of the problems that we encounter ares not a simple job to rectify. I recommend that drivers should have an annual air-con service. Possibly, at the same time as as your cars full service. Leakages take out all the gas present inside the air conditioner unit. This is probably the commonest problem that we encounter. Of course with the passage of time, the system becomes useless.

This attached video gives an excellent description of how the Auto Air Conditioning system works in most models of car.

This video represent a “Typical Auto Air Conditioning System – How It Works” as well shows the potential problem of over-charging systems with TXV Valves. Our solution at AC AVALANCHE is to use SMART CLIP Technology for the correct fill!

Car Air-Con Shock Price Rise-Car Air Con Recharge Prices Increasing Across the Europe

Car Air-Con Shock Price Rise

Car Air-Con Shock Price Rise

Car Air-Con Shock Price Rise

Of course, this came as a shock to me. Hence, when Ryan Linton explained to me about the massive increase in the price of the car air conditioning gas? The increase will be massive? from about £37 to £300 per gas canister.

The increase has come from our beloved European Union although indirectly. Consequently, air-con gas used in many cars is classed as a pollutant. Much of it is produced in China. Because if this the EU in there wisdom have  put restrictions on the amount of gas that the Chinese export in tot the EU.

So, at the moment the reduction is about 11%. Although this only seems a small amount it puts a massive increase onto the resale price of the gas to the garages and the end users. Our customers?

The frightening thing is that the EU in all their wisdom are going to restrict imports further to a wacking 37%. The mind boggles. I suspect that our customers will not bother having their cars re-gassed. In my opinion we are now getting over penalized by these silly emission rules coming out of the EU.

As you may well have noticed, car air con recharge prices have increased all over the UK and Europe. This is due to EU HFC regulations. We explain whats going on and why.

A small light at the end of the tunnel may be the fact that many other influential car nations such as Germany are starting protest against these stringent measures. However, for the time being we in the garage trade will have to pay for the increase in price of the air-con gas. Of course this charge will have to be passed on to the customer.

Unless the EU changes its mind. Which I very much doubt then this will just be an added cost to the burden on the motorist.

Car Air-Conditioning (air-con)-Who would have thought that we Needed It?

Car Air-Conditioning (air-con)

Air-con was one of the last things that you would have needed here in the United Kingdom’s cool climate, but now that we have it in almost every vehicle, I do not know how we did without it? This time of year is when our customers are starting to get their cars ready for the summer and this includes have their Car Air-Conditioning system serviced.

I must admit though that I remember the pre-Car Air-Conditioning days of motoring on a hot summer’s day. In those days, the only way to cool down was to open the car’s windows and stick your head out of the window. Not only that I also remember when the cars windows would steam up in spring and winter, due to condensation, this has now stopped because of car air-conditioning fitted to most cars. We used to arrive at our destination dripping with sweat, with our legs sticking to our trousers and other bits, all because the cars did not have air-con systems

America was way ahead of us here in the UK as far as Car Air-Conditioning is concerned

Although they had far more hot days and they really did need it especially in the Southern states. Air-con in the car was actually invented and used in America as far back as 1939 and Packard were the first car makers to install Car Air-Conditioning as far back as 1940, and although it was a crude system compared to today’s cars Used Cars, it was

Car Air-Conditioning

Car Air-Conditioning service machine

better than nothing at all. In fact, it was Chrysler that was the first to introduce a properly integrated air-con system into their cars in 1953 as an optional extra. By 1970 almost half the cars in America were installed with Car Air-Conditioning and us in Europe were still miles behind.  

Car Air-Conditioning (air-con)

At the same time in 1970 the USA adopted a new “Clean air act”, but the regulations for motor vehicles did not come into force until 1990. This meant that the refrigerants inside the Car Air-Conditioning had to be re-cycled and a different refrigerant had to be used. The gas that we all use at the moment is the R134A, but we think that a newer gas will be used in the near future. European car manufacturers quickly followed suit and air-con was installed in all of the big production cars such as BMW and Mercedes and was quickly followed by the family car market, down to the small cars made by Citroen and the Toyota Yaris.  

Car Air-Conditioning (air-con)

The main parts of the car air-con system consist of the Air Conditioning Condenser Unit, compressor and evaporator and a few other parts that, these all work together to remove and cool the humidity that is in the air and circulate it into and through the car, the warm humid air is replaced with cool air at the temperature that you set it at. That is until things such as the Car Air-Conditioning Condenser start to go wrong.

It is a well-known fact that cars fitted with air-con use more fuel and so some drivers switch of the air-con when the weather is cold. It is in actual fact false economy to switch off your air-con in winter. This is an extract from the Autokool website…http://www.autokool.co.uk/faq_13.html

“It is false economy to turn the system off in the winter. This can lead to deterioration of the seals and gaskets in your system and, even more, rapid refrigerant loss. On the coldest of days turn the system on to ensure that the windows are demisted and the interior of the car is comfortable. Contrary to popular belief this does not greatly reduce your mpg or performance. With modern engines and increased fuel efficiency the cost of using your vehicle air conditioning system has been considerably reduced with modern advancements in engineering”.

Most modern garages are equipped to service your Car Air-Conditioning system on your car

And the members of staff at the garage should all be certified to use the equipment and handle the refrigerant that is used, so check out the air-con before the summer arrives and keep yourself cool and dry.

Skoda Octavia comes in for Air-Con Service including a re-gas after some Hot Sunny Days

The condenser was located behind the dash of the Skoda Octavia, making it a difficult task, with not much room to move and working space was tight Air-Con Service resulted in new parts

This time of year has been very kind to many garages.Up and down the United Kingdom (UK). Therefore,it may seem strange to people who live in other parts of the world. But here in the UK our Summers are very short. So,to be truthful we do not normally get much Sun.

The new Skoda is an excellent car. Space is never an issue.Since there is sufficient room for both front and rear seat occupants. Therefore, it is designed in such a way that it will be a comfortable place to stay in. Controls are properly arranged including the Air conditioning controls.Numerous storage compartments are installed. That will on a hot day  make staying inside comfortable.

Skoda Octavia

Old condenser removed from Skoda Octavia

As a result, after our very cold and snowy March. I did not have much hope of us having good Summers. However, I was completely wrong? and this year has turned out to be hot and Sunny. Including a bonus for us garages.

As a result, our customers have been roasting in their cars. Because, of the recent damp and rainy Summers, the motorists have been neglecting their cars Air-con systems and many did not work, giving us a golden opportunity to make a little more profit. I say little because of the fact that we are all still in hard times and the price of air-con has come down, here in Halifax.

Skoda Octavia air con problem

However, I decided to buy a new sign to put up in the garage, right at a set of traffic lights (very eye catching). The heat carried on from day to day, and air-con inquiries were coming in thick and fast. The only problem with air-con is that it takes about an hour to complete the cycle of checking and re-gassing, however, we did very well and most of our customers went away with a lovely cold car to drive in the 30c temperatures.

I say most of the customers went away happy, because some did not. These were the ones with faulty air-con systems on their cars, including the driver of a 56 plate Skoda Octavia.

He, unfortunately, had a faulty Air Con Condenser. This is the part that looks like a radiator and indeed does the same thing as the radiator. Instead of removing the heat from the engine it removes the heat from the Skoda Octavia and is hidden away, somewhere behind the dashboard in the Skoda Octavia. The air-con systems come in three main parts the condenser,compressor and evaporator all these combined take out the heat and humidity from your car.

Air Conditioning Systems work by the compressor pressurising the gas, which is also the refrigerant and then moves into the Air Conditioning Condenser creating heat, as in the car radiator this flows through the very small condenser tubes cooling down the heat and forming into a liquid again, this circulates around the system, converting the heat from your car into cold air again, it is rather like steam turning back into water again, the system operates under high pressure and the refrigerant used cools the Skoda Octavia again, all clever stuff.

Dale Linton one of my technicians was given the job of fitting the condenser and made the usual good job of it. The condenser was located behind the dash of the Skoda Octavia, making it a difficult task, with not much room to manoeuvre and working space was tight. Most air-con jobs work in very tight spaces. The job was completed and the customer went away in a nice cool car.

Bridgestone Turanza T0025 Tyres Fitted onto this VW Golf

Bridgestone Turanza T0025 Tyres

All this cold rainy weather is bringing all sorts of cars in for different things. As motorists prepare their cars for the summer holidays, coming up in the near future. As you can imagine this can be a busy time for garages all up and down the country. So, as customers want all the little jobs doing that have been put off. Hence, before they set off on their journey.

Bridgestone Turanza T0025 Tyres

New Bridgestone tyres

One of the things that has hit us most, is the number of cars wanting the Air-Conditioning looking at. At times we could have done with two machines. There was such a rush from the customers to get their air-con seen to(no signs of a recession here). Another problem that affects the motorists in hot weather is the brakes.

We will start getting phone calls in the near future from people with noisy and squeaking brakes as the hot dry weather start to take its toll on the brake pads. All the dust from the pads and from the dry roads, start to accumulate between the pads and the discs and build to make the brakes very noisy and requiring attention from the garages.

Wiper blades also wear faster in the heat. The build up of dust and insects require us to use our wipers more often. In the winter time we use the wipers to clear away the water from rain and snow. But in summer we use them to clear away dirt and insects . So they will not use as much water and therefore come under pressure from friction, and friction means greater wear thus they wear out much quicker, so make sure that your window wash bottle is always full and the correct anti-smear washer liquid is used, there is nothing worse than a smeared windscreen with the Sun shining through the screen and you can not see anything.

Special car for a set of new tyres

This week we were asked from a customer for a new type of Bridgestone tyre. Bridgestone are one of the worlds leading tyre manufacturers. As a result we could offer the guy the Bridgestone Turanza T005 tyres for his VW Golf. If you would like a great review about these tyres please click the link.

A second car followed very shortly a stunning Aston Martin. Also wanting replacement Bridgestone tyres. It always makes me proud that customers trust us to have Bridgestone Tyres Fitted . Especially on these very expensive cars. Of course this is why we always keep up to date with the best fitting machines and of course my excellent fitters led by Alex Bray. The tyres were over £1000.00 for the set and the customer let me use a few pictures of his car for my blog, many thanks to him.Bridgestone Tyres Fitted

Air-Con Service-Service your cars AIR-CON the weathers getting hotter ?

America invented Air-Con for cars in 1939 now in almost all UK cars.

Air-Con Service-Our weather here in the UK is forecast to get get hotter this Summer. The weather companies including the BBC have said that a high pressure system is due to start building.

 Although motorists are feeling the pinch.With the economy and the price of fuel. It could be a nightmare stuck in your car with the kids screaming in the back.Just because they are too hot. We all know the feeling. Especially on roads like the A14 and M11, busy holiday destinations. Where there are always traffic jams whatever time of day. You can be guaranteed of getting caught up in a huge snarl up.

 Air-Con Service

If this happens and the temperature reaches 30 degrees. Thus, you will definitely need your cars Air-Con working. Also now is time to have your Air-Con serviced. It is no good leaving it until you are on your journey. If you are driving on the Continent and your AC fails. It could cost you up to 10 times the price as it does here in the UK. In France. A friend of mine , (who lives there). Always waits until he visits the UK to have his Air-Con Service. Also buys tyres and batteries, because of the price difference.Especially, between here and the other European countries.

Just out of interest.The first air con- system for a car was invented back in 1939 by Packard, in America and was the first to be fitted in the factory in 1940. The first refrigerant originally used was highly damaging to the atmosphere, and a safer gas was later used in the 1960s.

Air-Con Service

Here at Pellonautocentre in Halifax GB. We have many customers that have an annual Air-Con service. This ensures that their car performs properly all the year round.It ensures that  their  system works without a hitch. This will clean out all the dirt and germs that have built up in the course of time. It will also recharge the gas as necessary. The other option would be to leave yours on until there is a drop in the  temperature and performance.

This way will leave a risk of leaving yours on  until there is a problem, the problem may arise with the result in a bigger repair and service bill. Either way, in between summers, you do still need to think about your air conditioning system, we recommend that you leave yours on all through the autumn and winter, this stops the gas pressure from falling. Most of the public do not know that you should leave the Air-Con on all year round, but I do understand that the cars now coming out with smaller and greener engines will use more fuel with the Air-Con Service in cooler weather. Any bad smells coming from your air- con system should be checked at your nearest Autocentre for a Car Service, if you do not know of one in your area look online for your nearest Unipart Car Care Centre

air-con service machinewhere you will get free advice on what to do with your car  Air-Con System.

In the Halifax area of West Yorkshire, you can have your Air-Con Service done by experts, and should be looking to pay around £45 for a complete Air-Con service.

Air-Conditioning Time-Service your cars AIR-CON the weathers starting to warm up ?

Air-Conditioning Time; Air-Con was invented in 1939 in the USA

The weather here in the UK has now started to get warmer, and it is generally the Air-Conditioning Time of the year that motorists turn their air conditioning on and find that it isn’t

working as good as they would like. Sometimes the won’t be getting cold, and sometimes there will be a musty sort of smell coming from the inside of the car. It is just not the same driving on a hot day with the windows wound down. You will probably find that your air-con needs to be re-gassed, or a more thorough service and inspection may be required.

Just out of interest, the first air con  system for the car

was invented back in 1939 by Packard, in America and was the first to be fitted in the factory in 1940. The first refrigerant used in air-con was thought to be  highly damaging to the atmosphere, and a safer gas was later used in the 1960s.

Most of our customers know that it is  Air-Conditioning Time choose again and choose to have their air conditioning serviced yearly. This will clean out all the dirt and germs that have built up in the course of time, it will also recharge the gas as necessary. The other option would be to leave your air-con until there is a drop in the air con temperature and performance. There is a risk of leaving your air-con until there is a problem, the problem may arise with the result in a bigger repair and a bigger bill. Either way, in between summers, you do still need to think about your air conditioning system, we recommend that you leave the air-con on all through the autumn and winter, this stops the gas pressure from falling.

Many motorists are under the impression that Air-Conditioning Time is just for hot weather. In fact, you will need to use it all year round, otherwise, it will be highly unlikely to be working properly on the hot days we do have, (as we are experiencing at the moment) In the colder months of winter, you can use your air- con system to warm the car, and it will also remove moisture from the air so that windows do not get misted up, this something that drivers do not know.

If your car is fitted with climate control it is often tempting on really hot days to turn the cold button as far down as it will go, but unless you are on a long journey, the chances are the system won’t be able to achieve the low temperature that you are looking for. Then when you exit the car, you feel like you’re stepping into a hot, steaming forest. Not very comfortable at all. You are much better off aiming for an in-car temperature of just a couple of degrees lower than the outside temperature. You will feel more comfortable in the car, and it won’t be such a shock when you get out of the car, (we have all been there, when we hire a car in say Spain and the inside of the car are nice and cool, then when we get out it’s like stepping into an oven), if you don’t have the inside temperature so cold then your body won’t get such a shock when you hit the heat.

Any bad smells coming from your air-con system should be checked

out by a good auto-centre as soon as possible, particularly if you or any of your family has any breathing problems such as asthma. It indicates that there are bacteria in the car’s air-con system (often caused by leaves going mouldy and blocking up the exterior vents in Autumn, so do remove any that you see there!) you can also smell the bad smell coming in from other cars, this is very common and nothing to worry about.

In the Halifax area of West Yorkshire, you can have your air-con serviced by experts.

conditioning unit is much more complex.

Your cars air- conditioning unit

is a system that works much like your own bodies blood system. The air cons compressor is the heart that pumps a refrigerant called EPA throughout the Car Air Conditioning Service unit .EPA, a combination of gas and liquid, causes the air to cool when it is compressed. When the EPA coolant levels are low your air con will not work, this where an air con check over is required. In the check over the freon levels will be checked. Like your ordinary household air conditioning unit, your auto air-conditioning system will not work as it should when Freon Gas levels are low. Make sure you have a mechanic check Freon levels regularly before the unit experiences a major breakdown.

To make it possible for the EPA coolant to carry the heated air away and leave the car with cold air depends on the pressure that is applied to it. Air coming into the condenser helps in this process. This is the reason why, sometimes, for older models of air conditioners, the temperature is cooler when the car is travelling at full speed than when it stands idle. This allows the compressor to pump EPA coolant harder and faster. Therefore, this helps the air- conditioner system to operate much more efficiently.

As I have said earlier the first time we start having hot weather is when we turn on the AC button and nothing happens. We have all done it ?. The kids are shouting the wife’s boiling hot and shouting at the kids, all because the air-conditioning doesn’t work. More than likely the air-con system will be low on coolant fluid, and this can be corrected by checking with you local auto centre and having an air-con service, this costs around £50, but is well worth the money and leaves your car nice and cool on these few hot sticky summer days.

There are several things that can go wrong with your car’s air-conditioning

but the main problem is that you have had the system switched off for the winter/spring period and the fluid levels have gone lower, once again this will be corrected by a full Car Air-Conditioning Halifax UK service or Portable Air Conditioning Units

Many of us older drivers, will remember the days when air-conditioning, was only available on the top car brands. For this reason, i decided to put a few videos onto my blog. Naturally, most modern cars nowadays are now fitted with AC (air-conditioning). Most modern Autocentres, like Pellon Autocentre, here in Halifax. Accordingly, can now carry out repairs and re-charge many car models AC systems.

Therefore, Air Conditioning in cars came about in the 1940’s. The first ones were fairly basic. Hence moving forward to today’s vehicles, there is modern  technologies. As expected, such things as computerized automatic temperature control. Which allow you to set temperature that you want, automatically. For this reason, this has added a great deal of complexity to today’s modern vehicles air conditioning systems.

Furthermore, we now have tough environmental laws, that regulate car AC systems. Regulated things include, such things as recharging the  AC system with refrigerant. Another rule that regulates the AC system is the  evacuating and charging of the PAG oil needed by the compressor. Scientific studies have proved that there has been a damaging effect of the AC refrigerant to the Earths ozone layer.

Today’s modern garage now to have technicians. As expected, have to be certified on the use of refrigerants. Thus, can also repair your air conditioner system. As expected, we  purchased a special machine for  working and servicing on the cars with AC problems.So, as a motorist, basic knowledge of your air conditioning system is important knowledge to know. because it will give the driver more knowledge about the work that a garage has to carry out when repairing your AC. .

Modern AC or HVAC systems are composed of the following, COMPRESSOR, CONDENSER, EVAPORATOR, ORIFICE TUBE, EXPANSION VALVE, RECEIVER DRIER, or ACCUMULATOR.

Air Con Problems for the owner of this VW Golf ?

4-year-old VW Golf has Air Con Problems

As I have said many times this is the time of year that we can be busy rectifying air con problems on our customer’s cars. This year we are enjoying a nice warm sunny summer and because many of the new model cars have been fitted with air con as standard then the need for the air con to work and cool the car interior has never been more important. Many of our customers also travel to continental Europe for their holidays and so a good cold air con system is imperative for a good and comfortable journey.

air con

VW Golf with the old damaged condenser still fitted in place

There are many reasons why your cars air con can fail you, the commonest being that the customer switches it off in the winter time and when summer comes expects their  air con to work normally, but in over half the cases their system will need a re-gas. After the re-gas is when other problems occur. The main problem is that if the air con system is not used then the system does not get lubricated and consequently will dry out causing common problems such as failed “O” rings and rubber hoses, due to the drying out process.

Sometimes we may get a customer in who says that the car is blowing cool air into the cab, but not cold air. This is usually when the air con is set at high with the fans on high but the car is still only blowing in the cool air, we have all been there, you just can’t get the car cold enough? What we do in this case is first to check that the cooling fans are running on the Refrigeration Condenser (the thing that looks like a radiator usually at the front of the car’s engine) when the air con system is switched on. We also check out the condenser for any debris such as dead leaves, dust or insects that may be clogging the condenser up, you would be surprised what we find clogging the Air Conditioning Condenser Unit up?

We also check out the Pollen Filter or cabin filter as it is sometimes known as, if it clogged up then we will replace it. We then check the pressures of the air con system to see if they confirm what they should be set at in the user’s manual. The condenser is a very important part of the air con system.

It works the opposite way to the radiator (evaporator), it sits at the front of the car and air is blown over the condenser, but the air soaks up the heat and then cools the refrigerant inside the air con system. All this is done under high pressure, the air carries the heat out of your car and the refrigerant converts it back to a liquid. The liquid is then sent back to the evaporator (a low-pressure area) and the taking place of the system moving from a high-pressure area to low-pressure area forces the refrigerants temperature to perform a rapid drop and the cycle starts all over again, super cooling the cab of your vehicle (simple?).

VW Golf had an air con cooling problem

On a day last week, we had a car presented to us with this exact problem, we carry out all repairs and other work on car  air con systems here at Pellon Autocentre in Halifax UK.the air was coming out in the cab cool but not super cool. The car was a 2010 VW Golf (only 4 years old). The

air con

VW Golf with a brand new condenser fitted ready for a re-gas

the customer left the car with us and we proceeded to connect up our air con machine and re-gas the cars cooling system. The problem was spotted straight away because the car started to leak out the liquid from the condenser at the front of the car. After an examination of the condenser, we found out that car had recently had a minor bump at the front end, and consequently damaged the air con condenser. In earlier times this is what happened to car radiators nowadays this is where the air con condenser sits and so takes the brunt of any damage from stones or small accidents.

However this was one of our easier jobs to do and we replaced the condenser with a new one, re-gassed the system and the customer and his VW Golf went on their way, with a nice cold cabin their car.
