I plan to fit the unit myself i am a maint eng but have no experience with a/c basicaly my question is do i have a pope in hell of fitting it myself will be pre gassed (how do i tell) will 1200btu be enough to cool your average 3bed semi

A 12 000 btu will not cool a house. It will cool one room
And I would not advise you to try attempt fit it yourself
