What is a PTAC?
A PTAC (packaged terminal air conditioner) is a self-contained heating and cooling unit installed through an exterior wall, usually under a window. PTACs typically heat with electric resistance heat. A PTHP is the heat pump version. You'll find them in hotels, senior and assisted living, dorms, older apartment buildings, and offices where each room has its own control.

PTAC vs. split systems for apartments
PTACs are fast to replace (pull the chassis, slide in a spare), they keep one failure from affecting the whole unit's ductwork, and they need no indoor air handler closet. The trade-offs are noise, efficiency, and how they look. Split systems are quieter and handle humidity better but cost more to install. We cover this in detail in PTAC vs. split systems for apartments.
Keep turns moving with a spare-chassis plan
For buildings with many PTACs, the fastest repair is often a swap. We can help you decide how many spare chassis to keep on site and rotate repaired units back into stock. That keeps a failed unit from holding up a make-ready.
