So which aircon would you recommend for 1 room?
For 1 room, there are 3 ways of installing an aircon.
1. Window aircon ( Square little box at the bottom of the room ) - Provided your room has that.
2. Casement aircon ( vertical units sitting on the window )
** To both the above, you cannot install this 2 if your room window is facing the corridor.
3. Single split wall mounted unit. ( Must have a space to put condenser units.[ Aircon Ledge/Bracket] and power point to install. )
If you already have a aircon condenser in place, you will need to check with HDB if you can install another aircon unit.
With regular servicing, an Aircon's lifespan is approx 8-10 years
