Islandaire
The PTAC replacement house: drop-in chassis built for dozens of legacy wall-sleeve footprints, including brands that vanished decades ago. When a 30-year-old sleeve needs a unit today, this is the catalog that has it.
What they make
PTAC / PTHP
Lessons carry overThe under-window wall-sleeve unit in hotels, apartments and senior living — cooling with electric heat (PTAC) or a heat pump (PTHP), each serving one room.
Run capacitors, fan motors, plugged drains and matted coils — the RUNS-BUT-WON’T-COOL and GAUGES wings teach the same failures; dedicated PTAC tickets are on the roadmap. Respect the supply: many commercial buildings feed PTACs 265V, which is not the 115V habit you brought from residential.

Tech support
Tech support here is the guided Copilot with your Islandaire info already loaded — one question at a time, evidence before parts, and everything you enter rides into the service report.
Model-number decoding here covers residential and multi-family split systems and package units, 5 tons and under — Islandaire equipment lives outside that scope, so the manufacturer’s literature leads on model specifics. The Copilot still loads the brand for a guided session.
