My employers are moving offices, and part of their lease terms are that
they must return the premises to their original condition prior to
handing back the keys. 7 air conditioning units were installed at some
point since we moved in, and potentially they are required to remove
these before moving out (long story, but its 4 small units knocked
through together, however the external air-con units are sited on the
balconies of the 2 end units, meaning the middle 2 units external air
con units are 'tresspassing' if you see what I mean).

I've seen aircon units on ebay - but I wondered whether there was a more
formal 2nd hand market available for these units (4x flat ceiling
mounted Daikin + 2x wall mount Fujitsu + 1x flat ceiling Fujitsu).

Any ideas?

Thanks

David
