Air Conditioning Information


Preventative Maintenance

Preventative Maintenance starts with a regular check of your system. Including the following:

  • Visual Checks of the pipework & service ports
  • Check the tension of the drive belts
  • Check for signs of corrosion & damage to the Condenser (Front radiator on the air conditioning systems)
  • System standing & running pressure checks
  • System output temp check
  • Check for odours in the vehicle
  • AIR CON FILTERS - Condition checks
  • 12 to 18 Month Re-Gas Including oil replacement

With regular checks to the above you will minimize the chance of expensive repairs, keeping fuel costs economical or at least reduce the inconvenience of a summertime failure whilst helping to keep your impact on the ENVIRONMENT.




New Legislation comes into effect Jan 2011

Jan 2011 begins the phase out of R134a gas (the gas in your cars air con system, post 1993 cars). Certain catogories of new vehicles manufactured will have a new refrigerant with a GWP (Global Warming Potential) of less than 150 (probably HFO-1234yf ), with a total ban on R134a by 2017.

Another alternative refrigerant being considered is CO2, Whatever happens the result will more than likely mean more exspense to the service guy that will most surely be passed on to the clients, so be warned now look after you systems, service regulary, fix problems before they escalate.

In General

Since the invention of the automotive air conditioning system many things have undergone considerable improvements, such as "Climate Control" which allow you to set the desired temperature and have the system adjust automatically and improvements to overall durability.

The times of "DIY" repair to these systems, is a thing of the past. Extensive studies have proven the damaging effects of R12 Refrigerant to our ozone layer and its manufacture has been banned by the U.S. and many other countries that have joined together to sign the MONTREAL PROTOCOL, a landmark agreement that was introduced in the 1980's to limit the production and use of chemicals known to deplete the ozone layer.

Should a major problem arise from your air conditioning, you may hear words like "retrofit" and "alternative refrigerant" are now in the air conditioning technicians vocabulary. You could be given the option of "retrofitting" as opposed to merely repairing and recharging.

Retrofitting involves making the necessary changes to your system, which will allow it to use the new industry accepted "environmentally friendly" refrigerant R-134a. This new refrigerant has a higher operating pressure, therefore your system dependant on age may require larger or more robust parts to counter its inherent high pressure characteristics. In some cases will add significantly to the final cost of the repair if not performed properly may reduce cooling efficiency which equates to higher operating costs and reduced comfort.





The Ban

Strict laws govern the use of refrigerants used in air-conditioning systems and in October 2000, R12 was banned because it is an ozone depleting gas. If for any reason a vehicle with an R12 based air conditioning system requires replacement refrigerant, the system must be upgraded to take the more environmentally-friendly R134a gas.

R12 gas, sometimes called freon fitted in vehicles before 1993 produces phosgene (Mustard gas) when burnt with a naked flame. It has been banned in America and new EUROPEAN UNION LEGISLATION is being replaced here by the new gas R134a. The legislation has meant two things

From 1 October 2000 gas suppliers were no longer allowed to sell R12 refrigerant and From 1 January 2001 R12 can no longer be used in the servicing of air-conditioning systems.





The Importance Of Servicing

By spending a small amount on an annual or bi-annual basis you are limiting the risk of having to find a major fault.

Gas leaks naturally from all systems at 10 - 15% per annum. If this is left untreated, fuel economy is affected when the system is run. The compressor (which uses fuel) has to work harder to generate the correct temperatures when the gas level is low. This costs you money as it uses more fuel. In addition, the lower the gas level the greater the likelihood of component failure.





Allergies

With many people suffering from hay fever and other allergies it is perhaps not surprising that more and more people are discovering the value of air conditioning. Air conditioning allows for a comfortable and controlled driving environment. The removal of pollen particles is just one of the major benefits enjoyed by drivers of air conditioned vehicles.

Most people will be aware that air conditioning cools the air entering the driving compartment. On hot summer days this means that you arrive at your journey's end as cool, calm and collected as is possible!

In actual fact the benefits of air conditioning certainly go beyond this. In fact air conditioning does three things and it is worth keeping this in mind at all times throughout the year.

It cools the air - It dries the air - It filters the air.




Pollution

With high fuel prices,CONGESTION CHARGES, CONGESTION on the increase and occurrences of "road rage" it is perhaps not surprising that more and more people are discovering the value of air conditioning. Air conditioning allows for a comfortable and controlled driving environment.

The removal of particles and types of pollution are just part of the significant benefits enjoyed by drivers of air conditioned vehicles.




Winter Use

Many people will have at some time owned cars that simply do not like being stuck on a drive. When they are used frequently they sound better and are more responsive and operate with greater fuel economy. An air conditioning system is very similar. In addition good working order is best maintained through constant usage. The major risk of not using air conditioning for long periods is that system seals can dry out.
