My apartment, which I own, is split upstairs by two hallways. Each hallway has its own A/C unit, to cool 6 single person rooms each. Recently the south side A/C broke. I have called the repairmen out a few times and a couple days after they leave there's another problem, in the mean time the residents are complaining of the heat.
My question is, can I buy an air duct and connect the North and South hallway air conditioning ducts together? At least until I buy a new unit, or get it fixed.
(Yes, we called a different A/C repair company.)
