thanks sa mga replies fellow tsikoteers..
i was in the south area the past two days and was able to visit 2 shops...
1st, rapide alabang...lets just say it was the first shop i saw right after my "ac incident" happened and i had no choice.. i know how unhappy a lot of tsikot members are with the rapide shops..true enough, their mechanic did a ten minute or less check up and told me that i needed to have my thermostat changed..estimate 9k...wow...i knew i needed to get a second opinion..buti na lang
2nd, ceejays..read thru the forums and ceejays and mang mario were mentioned..since i was in las pinas earlier, i scheduled a visit to ceejays around 1pm...turns out, cleaning lang pala kailangan... i didnt think ito yung issue kasi the dad of my gf did his diy cleaning about 2 months ago..hindi pa pala cleaning yung nagawa hehe, as i learned from ryan of ceejays...ayun, by 3pm, everything was a-ok! and it cost me 7k less than what rapide estimated...talk about service!
will go back here again next time for cleaning...

got tips from the mechanic as well..
psi, sige next time baka pag urgent malapit lapit lang naman ang marikina sa kin...
ingat tsikoteers!
