After a few minutes, there seems to be an annoying hum which can be heard clearly when idle. If I turn the Air Con off it disappears.

 

The air con seems ok, but how much would an air con service cost?

Cool thanks.

ATS seem to have a £29.99 deal on at the moment. That any good?

ATS use a fully automated machine like this.

Never had an issue with either them or Kwik Fit for Air Con regassing. Wouldn't use them for much else though.

Had the a/c regassed and serviced. Seems to be much better now.

For any Wiltshire owners, Halls Electrical in swindon have a groupon deal at the moment. £29.99.
