i bought samsung inverter aircond from seng heng...the problem is when i switched on the aircond for sleeping, the next morning i have nasty headache...could be leaking gas?

EER higher on samsung but samsung not really professional or specialist in air conditional line.

Parts or after service may different case.
Just look at their design for triangle design, if you plan for used shorter than 10 yrs maybe that is worth for paying leases TNB bill.

in the 1st or 2nd models launched in malaysia from their casing plastic easily become like powder n really can crack the cover, but that those model has been passed over 10 yrs already & maybe the newer design they has improved a lot... TS why not to try it out..

Thanks

Mitsubishi has new inverter 1.0 and 1.5HP. MSZ-FH25/35 here. I called Melco and was told it cost almost 4K.  The COP and input W is impressive though bringing down the annual consumption to 940kWh and 1480kWh which is leagues better than what's in the market.

If you can afford that price for me is worth it... High COP or EER = pay lesses of monthly bill and also come with bigger outdoor unit size to compare as MSY-GJ10VA model.

Last 3 months ago, my common room just installed that older MSY-GE10VA model for last unit only, if i found it had launched i should instead of MSZ-FH25VE for my common room.
