Ask a proOn a two-pipe system, the building supplies either hot or chilled water, not both. In spring and fall, your fan coil may be getting the “wrong” water until the building changes over. On a four-pipe system, the cause is more likely a valve or control.
A clogged condensate drain or overflowing pan is the usual cause. Cleaning the drain and pan each year prevents most leaks onto the floor below.
PTACs in converted buildings can rattle from worn fans or loose panels and let in cold air around the sleeve. Resealing and service help.
Ask management whether your building has a two-pipe or four-pipe system and when it changes over between heating and cooling. That answer explains many spring and fall complaints before anyone opens a unit.
Most buildings require a certificate of insurance from the technician’s company, set hours for work and a freight elevator reservation for replacing equipment. Getting those arranged first avoids a wasted trip.
