While most air conditioners are single stage, meaning they're either on or off, this air conditioner can heat or cool at two different speeds. Most of the time the unit will meet cooling needs at its lower speed, resulting in balanced and consistent temperatures with lower energy use.
Efficient and Affordable
The ML17KC2 offers energy efficiencies of up to 18.00 SEER2, delivering comfort and energy savings at a more affordable price.

AC evaluation
January 10, 2026Unit works well and although hard to pull its electricity separate from all other home use, I think the monthly bill has lowered a bit. That is difficult to calc as our weather this winter is hotter than ever before so there are more days in which AC is needed than normal for November and December. This is the sort of review that should come 6 to 10 months after it is put into action.
