What the published numbers mean before you compare every spec.
18,000 BTU is closest to ENERGY STAR’s 700–1000 sq. ft. room-size row.
ENERGY STAR sizing chart ↗At 5°F, certified output is 11,900 BTU/h — 66% 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.
208/230V equipment; confirm the dedicated circuit and disconnect requirements with an electrician.
Manufacturer spec ↗HSPF2 9 is below the 10.2 average among 125 models in the same rounded capacity class.
ENERGY STAR ↗Your room is near 700–1000 sq. ft. under the ENERGY STAR starting-point assumptions, and a load calculation agrees.
Your electrical plan does not yet account for 208/230V 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.
