After a couple of years of suffering from heat exhaustion in the polo because i thought the compressor had snuffed it, i decided to bite the bullet and get someone to have a look at it.
I called in CoolCar, a company found on the internet and he came out to have a look at it. Straight away he said it looks like a gas problem as his test instrument was bouncing around like a good un. He did a full check of each component associated with the air conditioning to make sure they were all working properly which they were (a big bonus for me as i didnt need to replace any parts).
He did a full service which included draining the system, checking all the components out, re-oil the compressor and insert a dye in the system so it can pin point any leaks, then he re-gassed the system and BINGO........I have freezing cold air conditioning again
It cost me a total of £60 for the service and re-gassing of the system and he even came round to the house to do it.
Cant recommend these guys enough, really nice chap
