ENERGY STAR ↗

DIY status not confirmed

The cited fields do not confirm a pre-charged line set or DIY-line designation for this model.

Electrical service

208/230V equipment; confirm the dedicated circuit and disconnect requirements with an electrician.

Manufacturer spec ↗

Heating efficiency in its size class

HSPF2 8.5 is below the 10.2 average among 125 models in the same rounded capacity class.

ENERGY STAR ↗

Good fit if…

Your room is near 700–1000 sq. ft. under the ENERGY STAR starting-point assumptions, and a load calculation agrees.

Think twice if…

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.
