- Heating and ventilation problems
- Bacterial treatments
we sell & fit quality products that we and you can have complete confidence in to do the job they were made for.
Automotive cooling services is a Diavia & Eberspacher auto air conditioning installer plus a Hella air conditioning centre
Air conditioning kits.
Why do air conditioning systems need to be serviced?
:Because up to 10 % of the refrigerant is lost every year.
:Because, otherwise, the compressor oil supply is no longer guaranteed.
:Because humidity in the system can cause expensive repairs.
In contrast to what some vehicle manufacturers say, vehicle air conditioning systems must be serviced regularly. Every year, up to 10 % of the refrigerant is lost from the system naturally through hoses and connection elements. This means that the cooling capacity is noticeably reduced after only three years. In addition, the refrigerant that circulates through the air conditioning system serves as a carrier medium for the oil which is also in the system. The air conditioning compressor requires this oil as a lubricant. If there is not enough refrigerant in the system, the compressor may no longer be sufficiently lubricated. This can lead to complete compressor failure. The necessary repairs can quickly run up a bill of
£ 700 and more. This can be avoided if the air conditioning system is checked once a year. In addition, the refrigerant absorbs humidity from the outside via the hoses. Part of this humidity can be trapped by the dryer in the air conditioning system. The saturation point can be reached after 2 years of operation. If the dryer is not replaced regularly, the high water content in the system will lead to corrosion. Increased wear and mechanical damage to system components are likely to follow. The expansion valve could also ice up. This can lead to considerable problems, possibly to complete failure of the air conditioning system.
High repair costs can be avoided by replacing the dryer regularly

The Air Conditioning System components
The vehicle air conditioning system is a combination of vehicle heating and refrigerant circuit.This makes it possible to create the required climate conditions, completely independent of outdoor conditions.This makes the air conditioning system a major factor for safety and driving comfort. The individual components of the refrigerant circuit are connected through hose and from a closed system. Within the system the refrigerant circulates, driven by the compressor.The circuit is divided into two sides:
:The part between the expansion valve and the compressor is the low pressure side (blue)
:On the over side of the expansion valve and the compressor is the high pressure side (yellow/red)
The gaseous refrigerant is compressed in the compressor and thus heated up considerably.It is then pressed into the condenser under high pressure.This results in heat to be withdrawn from the heated refrigerant,which leads to condensation i.e its state changes from a gaseous to liquid.The dryer is the next step in the system,which separates pollutants and air inclusion from the now liquid refrigerant.This ensures the effectiveness of the system and protects the components from damage.From the dryer the circuit continues to the expansion valve.This valve can be compared to as barrage.In front of the barrage it maintains consistent pressure, whereas this pressure is allowed to relieve behind the barrage,due to its change in volume. Since the expansion valve is located in front of the evaporator,the refrigerant relief passes into the evaporator. During evaporation i.e when changing the state of aggregation from liquid to the gaseous,latent heat (evaporated cold) is released.This evaporative cold is now blown into the vehicles interior.At the low pressure side the refrigerant now flows back to the compressor to start the circuit from the beginning.
