Additional extras

COOL-SHot

Using Cool-Shot will improve the performance of the system, creating a cooler environment, whilst using less energy and increasing the ac systems lifespan saving money in the long term.

Cool-shot comprises of two synthetic catalysts and a lubricating agent, which removes the build-up of oil on the walls, allowing the refrigerant to improve its heat exchange properties.

Using case histories interesting data has emerged using cool-shoot.

  • Up to a 5-degree improvement in cooling at air vents.

  • Faster cooling performance

  • 73% better heat exchange

  • 20% reduction in fuel costs to run the compressor

  • 54% increase in compressor lubrication

  • 50% increase in compressor lifetime.

  • A decrease in compressor vibrations and noise.

  • Cool-shot acts without causing any chemical changes to the oils or refrigerant and is 100% ecological.

Using Cool-shot will pay for itself in no time at all, using less energy to run the compressor and fewer maintenance costs and quieter operating noises.

Anti bacterial treatment £10

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.

 

  • Kills the mould and fungi that can affect your health and driving comfort

  • Improves air quality

  • Deodorises the interior of the vehicle

  • Removes build-up of bacteria colonies.

  • Includes a complete inspection of the entire air conditioning system.

  • Gives you and your family the peace of mind that you're travelling in a cleaner and healthier environment.

How Car AC works

c84f44dd422fbffc3c714b65e600b214.gif

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!
