My Mitsubishi System 3 compressor (MSYGE24VAR3) that's nearly 5 years old, control board is a bit faulty, causing one of the expansion valve to not fully close, so whenever I switch on my bedroom's aircon, the aircon in another bedroom is dripping water from the condensation (aircon gas continue to supply to the aircon unit despite it being switched off) and putting pails/towels under the water drips is not a long term solution and run risk of damaging the wooden floor.
My usual aircon company advised that although ultimately it is my choice, in their opinion it is not economical to repair/change the outdoor unit's control board and the faulty expansion valve. The cost would not be far off from paying $1k+ to buy a new outdoor unit (supposedly no stock now if buying outdoor unit only).
However if I choose to buy a new outdoor unit alone, Mitsubishi does not provide any warranty (can't understand the logic from Mitsubishi though, a consumer buying a new product but no warranty is granted). If I want the standard warranty, I have to purchase a full set of outdoor unit with 3 aircon units.
While the aircon units are still working fine and is a waste to replace, I do suppose it makes some sense to change the outdoor and indoor units together, effectively I'm "renewing" 1 year spare parts and 5 years compressor warranty. Anyone has a different opinion?
They recommended the Starmex FN series for reliability and alternative option of Daikin iSmile series (only $100 more than Starmex so price difference is negligible for me) if I want smart control capabilities.
Anyone using Daikin iSmile series can share if the smart control capabilities are really useful? Practically I can only think of 2 benefits:
1) Use mobile phone to change temp/fan speed instead of remote control.
2) Can switch on aircon remotely in advance, but then this only makes sense if you are switching on your living room aircon provided balcony doors & kitchen windows are fully closed or if you are switching on your bedroom aircon provided the bedroom doors are closed (most people's habit is probably to leave it open when aircon is not in use).
Also I can't seem to find on Daikin's website to confirm that their warranty for compressor is also 5 years. Only mention 1 year for spare parts.
