That is an interesting topic about lack of qualified engineers to work on Warm Air Units..

When i revalidated my uk licence ACS...I definately felt a lack of interest in the WAU licence..

All other ACS classes had over 60 participants where as the WAU class had myself and 3 others???????

True enough i service and repair 10 systems a day an id guess that ive only saw 4 WAU this year ..

I hear that alot of Warm Air Systems are being removed..

Is this a concern over the whole of the UK or is it just windy auld Scotland??
