What temperature approx, should the air at the front central main air vent be, in vehicle with a fully gassed a/c, working near its max efficiency, given average outside ambient temp [eg. 20 Degrees Celsius App.].
Just after an approx. Guideline, to work towards, I realise there are a lot of variables.

Many Thanks,
G.K.

Hi there,

If you can get it down to 3-4 Deg C your doing well, more like 6-8 Deg C will depending on dew point Humidity, refrigerant, T X valve and about a dozen other variables, just as long as it's cold. Any way the temp at the vent is a false reading, it should be take at the floor with a wet bulb thermometer to be accurate.
