[quote=dealermate;1305508]General cleaning lang po ng evaporator kailangan mo kaya humihina blower mo pag long run kasi nag yeyelo ang evaporator dahilan para di makalabas ang hangin[/quote

i agree with dealermate, this points out to evaprator icing caused by any or more of the following:
dirty, clogged evaporator
low charge and pressure
marginal operation of an expansion valve (expansion valve system)
restricted orifice tube ( closed cyle orifice tube type)
dirty or partially clogged inlet air filter
