Hi Jayne123,
I fully agree with you.
I'm sorry, but I can not picture where the units are to be placed. Does anyone have any details or photographs? Will a crane be required to lift the units into place? Will some form of crane (hi-ab) be required to get workmen on to the rooftop?
Is it just the condenser that is up at penthouse level or is the evaporator there too (any A/C engineers out there?)
I do not see it being a big problem to fit A/C units on individual terraces but it will be expensive to retrofit and will involve taking part of the ceiling down to tap into existing trunking. Perhaps this should be at Rudina's expense if access is limited at the original place or the original design suspect.
