So I bought a new one, a Keystone KSTAP14B, which should be powerful enough to cool the whole place, at the very least with the doors closed so that it's only cooling the living room. However by using the collar supplied in the kit I managed to get the end to fit in the original manufacturers end fittings that came with our AC unit which had to be secured with tape supplied in the kit.

I think I'll stay with the existing hose, then, and continue to perch the unit on its box as I've no wish to risk the health of the unit by fitting a longer hose than is good for it.
