Advice Needed - Split system for 13ft * 10ft room

Hey All,

I need a split system in my home office as it get very hot due to it being a corner room which gets a lot of sun and having a workstation and a lot of electronics running.

I've been quoted $1600 for a 9000BTU system, based around a split system from 'Classic'.

I live in the Cayman Islands - everything is more expensive here so I'll understand if this seems like a lot.

So, a couple of questions;
1 - Has anybody hear of 'classic' air con units? I can't seem to find any info about them. The contractor told me that they were a budget model and they cheapest they had but should be fine for the small area I need to cool.

2- How difficult is it to install one of these? Could I install one with an electricians help?

Thanks in advance,
James
