- Collect model specs: model number, Cooling Capacity, Input Power, annual energy use and compressor type.
- Verify the units: do not treat BTU/h as electricity use and do not rely on a marketing “18k” class without the official value.
- Run your room: open the checker, enter dimensions, city, sun, insulation and windows, then save the result URL for model-to-model comparison.
- Read the reason: PASS, BORDERLINE or FAIL starts a review of the model; it is not a performance guarantee.
Start with the checker: if you have a specific unit in front of you, use AC Fit Check first, then return to the guide that explains the result.
