Extended warranty : should cover indoor & outdoor PCB main board & fan motor else, wires is never covering is guess, outdoor compressor was standard 5 yrs from argent.
Like installation PVC outlet pipe was clog & maintainance by serving only.
Thanks for the reply. I tried reading the term and conditions on gain city website for the extended warranty. It does not say anything about quarterly servicing/maintenance is required to qualify for the 5 yrs warranty. But I searched this huge thread and came across one post that claims that quarterly service is required for the 5 yrs extended warranty by gain city. Only 1 bedroom aircon will used mostly the rest will be used occasionally only so servicing quarterly is abit too much and the main purpose I get mitsubishi is coz its easy to clean so that I can clean it myself.
