i went to koolaire sri petaling before...i drive a satria...i think its better not to go there lah...try to find sumother threads...there were sum guys talking bout this before...i kinda forgot where it is...last time i went there...they asked me wanna service my compressor or not...so i said ok lah...u know how much they charge just for taking the compressor out, pour out oil from there...pour in new oil...oil price is not included...they charge me 75 bucks just for that...i thought they said compressor service...they'll open the compressor n cleanup the thing inside...i thought wrong...but nvm, good lesson 4 me...never will go there again...anyway...this is just my opinion...
