Check the room and the installation together
The guided selector combines an approximate room-capacity estimate, actual electrical answers, heating and manufacturer sleeve relationships. An old-model replacement is one of its installation paths. Missing or disputed facts remain checks rather than passing a filter.
Research with a visible paper trail
We organize manufacturer manuals and technical documents into model and sleeve records. We identify the sources and conditions behind a compatibility claim and distinguish missing information from a known conflict.
Our current scope
The catalog includes reviewed profiles with incomplete requirements. They can help identify an option, but cannot become a confirmed selector result until the relevant requirements are established. PTAC equipment and contractor matching are outside this catalog.
Wall AC Fit is an independent research project. We do not claim to have physically tested products or performed installation work.
