Anti bacterial treatment
(Included in full service)
When air conditioning isn't in use, condensation builds up on the evaporator and becomes a breeding ground for bacteria and fungi. When warmer weather arrives and the air conditioning is turned on, these unpleasant and unhealthy bacteria can be vented into the cabin. You may notice there is a problem because of an unpleasant smell, however quite often you can't tell you are breathing in these harmful bacteria at all.
Have you ever got in your car, pushed the AC button and had a terrible smell fill the cabin? That smell is bacterial growth. A vehicle's air-conditioning system provides the perfect environment for bacteria to grow. The AC system should be kept clean through the use of anti bacterial treatments and replacing the pollen filter. This will keep the air in your car safe and odour-free.

How Car AC works
The Air conditioning system consists of these parts:
-
Condenser
-
Compressor
-
Receiver
-
Dryer
-
Evaporator
-
Expansion Valve
The Refrigerant enters the compressor as a vapor and is compressed by the compressor, where the pressure increases and it enters the condenser at the front of your car (looks like a radiator) where it is collected and it turns into a liquid.
The liquid refrigerant then enters the evaporator under pressure (Look like a radiator, that is hidden behind the dashboard). It then turns back into a vapor, and due to the laws of physics it supercools, and warm air from the interior of the car is blown over the evaporator, which extracts the heat into the refrigerant, It then enters the compressor again and keeps repeating the cycle.
​
​Using your air conditioning system keeps it working efficiently if you do not use it the seals may dry out and cause leaks. And, any moisture trapped in the system can cause acid to attack the components, so use it regularly to keep it working and prevent garage bills!
