Share ko lang yung AC repair with my Adventure.
Six years na yung Adventure sa amin, yearly ko pinapalinis yung evaporator, since walang cabin filter yung AC ng Adventure.
Recently, hindi na talaga sya ganon kalamig. Kahit na bagong refill pa ng freon (actually 2x ako nagparefill).
Pinapalitan ko yung expansion valve at dryer, ayun, bumalik na yung dating lamig.

CMIIW, if you have your car serviced sa CASA, SOP na nila yung pinapalitan yung expansion valve and dryer. These two parts are wear-and-tear items, unlike the evaporator, condenser and compressor. The dryer is like an oil filter. Every time you have an oil change, pinapalitan yung oil filter. So ideally, everytime na pinapabukas mo yung AC, kelangan magpalit ka ng dryer dahil nacocontaminate ng hangin yung materials sa loob ng dryer.

HTH.
