Inverter - Expensive, but in the long run you will save more money.
Non-inverter Not expensive, but it will cost you in a long run because of the high consumption on your electric bill
Note: there are non-inveter aircons that are not split type so it's not space consuming.
Depende sa ts sa kung ilang oras mo gagamitin ang AC mo, kung 4 hrs lang pababa ang oras na gagamitin mo siya mas ok ang non-inverter, pero kung mas matagal sa 4 hrs ang gamit mo sa AC, mas ok ang inverter
