Air conditioning used to be luxury, now it is fitted to almost 80% of new cars on today's roads. With increasing traffic and road congestion set to worsen vehicle air conditioning makes a lot of sense.

Air conditioning is designed not only to create a comfortable atmosphere during the summer months but by filtering, cooling and drying the air in the winter it can provide a damp free cabin not to mention steam free windows.

There are two commonly known vehicle air conditioning systems - straightforward air conditioning ( A/C ) and Climate control. The principles of both systems are basically the same; climate control however is more intelligent and can be set to monitor the cabin air temperature automatically.

Air conditioning is designed to work along side a vehicles normal system but is often overlooked when a routine service is carried out. Due to natural refrigerant leakage of about 10-15 % per annum most manufacturers recommend an air conditioning system be serviced every two years. Unfortunately it is an ever-increasing fact that most drivers do not realize there is a problem until their air conditioning fails to blow cold. Air conditioning systems if not maintained correctly can be costly to repair, for example, most compressor failures (often the most expensive component in the system) could have been avoided by early diagnosis of a leak which would allow moisture into the system causing unwanted corrosion.

What's involved when HallCraft service an air conditioning system?

Initial Checks : The refrigerant type is identified. Vent operations and temperatures are checked.
The refrigerant is then recovered from the system and electronically weighed.
The compressor oil is checked.

System Check Over : Various components of the system are checked inc drive belt, condenser, pipe work and pollen filter (if fitted). If requested the dryer / accumulator is changed at extra cost.

Evacuation : Evacuation of the system is carried out; a vacuum is applied to remove unwanted air and moisture from the sealed system. The vacuum is then held for a period approx 20 minutes this identifies if there are any leaks in the system. If no leaks are detected we continue.

Re-Gassing : The manufacturers recommended amount of refrigerant is electronically weighed and charged into the system along with specified oil and a leak detection dye.

Final Testing : Vent temperatures are re-checked and if necessary a disinfectant is administered to the ventilation system at extra cost.
