I clean up my evap coz the dirt would clog up and the water will spill through the mat (normaly underneath the engine bay) .(experienced once my mat got wet!)
Mga sir ano po tips to prolong Compressor,Condenser and Evap? or whatsoever A/C parts sa aircon..
regularly replace or keep your AC filter clean to prevent contamination of your AC components.
and regular AC system cleaning/servicing will keep your AC in good running condition for a considerable amount of time
