Most everything over 5 tons is going to be 3 phase

If I were engaged by your landlord, I'd be advising them that you've been
adding considerable heatload to his premises and have been using spot
coolers with the heat being extracted to the base building air conditioning
via the return air and thus compromising conditions for other occupiers. I
would also make sure that the additional operating costs including added
wear and tear plus any service calls which could be attributable to your
compromisation of the thermal comfort of other users all be billed to you.
You've got the load (fact), yet you're still farting around getting advice
from a bunch of techs who do domestic servicing of HVAC and very little
commercial and maybe they've been in a datacentre once or twice in their
career (yet still know little about vapour sealing, which you obviosly don't
have and sensible heat load which you have bucketloads of). So get on the
phone and take your problem to a proper expert who can measure, assess and
design a proper solution. In any electronic equipment room in the US I'd
have to say the best call would be to get in Liebert who at least understand
just how horrible a job you're currently doing and may even take so much
pitty on you that they'd actually give proper advice.

Assuming this is a multi-dwelling rental?
