The A/C market
Yesterday considered as luxury equipment, the
air conditioning widely became more democratic
today and now equips 90% of new vehicles in Europe.
As a consequence, inquiries for Air Conditioning main-
tenance and repair follow the same evolution and
are a real opportunity for workshops to increase their
revenues.

equipment leadership
to aftermarket excellence
In this framework of important and continuous
growth, Valeo Service is proud to present you the
2013 Air Conditioning technical handbook,the first
step to a fully renewed technical collection. More
and more customers are expecting to be advised

ponents, this book will allow you to rediscover the
air conditioning system. More focussed operations
on the A/C system will be treated through techni-
cal bulletins and videos.
