What the published numbers mean before you compare every spec.
12,000 BTU is closest to ENERGY STAR’s 450–550 sq. ft. room-size row.
ENERGY STAR sizing chart ↗At 5°F, certified output is 6,500 BTU/h — 54% of its 47°F rating.
ENERGY STAR ↗The cited fields do not confirm a pre-charged line set or DIY-line designation for this model.
115V equipment; confirm the dedicated circuit and disconnect requirements with an electrician.
Manufacturer spec ↗HSPF2 10 is below the 10.5 average among 128 models in the same rounded capacity class.
ENERGY STAR ↗Your room is near 450–550 sq. ft. under the ENERGY STAR starting-point assumptions, and a load calculation agrees.
Your electrical plan does not yet account for 115V equipment, or your room falls outside the sizing range above.
Room guidance is a screening estimate for standard conditions. Check your room inputs; use Manual J for final sizing.
