Air Conditioning

Hi, Does anyone know the expected temperature readings obtained by measuring the central air vents with a temperature probe, whilst the air conditioner is running.

Thanks, Laura....

This will depend on whether you have specified a 'goal' temperature on the climate control or whether you have it set to full cold, also the temperature of the air it's trying to cool, e.g. if its 25 degrees outside and your trying to cool the air it'll have a harder time than if the temperature was 20 degrees.

I did read a while ago though that the temperature when set to full cold running at peak efficiency should be somewhere around 8 degrees.

Just from memory I thought it was 4 deg C at the vents

Most vehicles are between 4-6 degrees at the centre dash vents on manual full cold, max air throughput.

Thanks for all the responses, now need to find a suitable temperature probe for testing.

Maplin do a £20 digital thermometer, or a cheaper £15 probe type.

Why don't you take it into a Kwik Fit site and get them to "service" the AC, they had an offer that if they couldn't get it 10% lower than the initial reading the service was free.....worked on my wifes BMW

I know people shy away from the Kwik-Fit chains but its worth a try....they don't even have to lift a spanner everything else after unscrewing the AC caps is automatic on the machine, the same machine as Lexus use I expect!
