Read guideHow to choose the right portable AC guide
Use the general not-cooling guide when you need the broad checklist. Choose the fan-runs-but-not-cooling page when air movement is obvious but real cooling never arrives. Choose the room-hot page when the machine runs but the space still feels overwhelmed. For water issues, start with the broad leak guide if the source is unclear, the bottom-leak guide if water is under the cabinet, and the floor-leak guide if cleanup and containment are the immediate priority.
Portable AC guides on this site focus on setup, airflow, drainage, room load, and safe shutdown decisions. We do not recommend refrigerant work, compressor work, or opening sealed cabinet sections. If a leak reaches wiring, the breaker trips, or the appliance smells hot, stop troubleshooting and arrange service.
That separation matters because a weak cooling complaint, a room-load complaint, and a water-leak complaint often point to different first checks. Choosing the nearest symptom page gives you a clearer path and reduces the chance of mixing setup problems with actual component failure.
