Hi guys, the aircon in my ef fairmontnis doing a shot job at cooling anything. Is this a normal thing or do i need to get the system regased?

Is the compressor engaging? Could be anything... A gas leak (which has to be fixed before you can have it regassed)... Blocked evaporator... Blocked condenser... Blocked line... Shot compressor...

To get it regassed the current gas will need to be pulled out and measured amount go back in because you wont know how much is in there and you can't overcharge the system...

A air con person can probably stick some gauges on the system and at least check the pressures to see if the system is working... Might give you some idea...

Cheers,
Tim
