Heating Capacity Comparison (4 Ton)
This chart illustrates the heating capacity (BTU/h) of the "M-1 Ultra" model against "Company B" and a "16 SEER" benchmark across a temperature range from -22°F to 48°F. The "M-1 Ultra" demonstrates superior heating performance, maintaining a higher capacity at colder temperatures, particularly from -22°F up to 18°F, compared to the other models.
Heating Capacity Comparison (5 Ton)
This chart presents a similar comparison for the 5-ton model. The "M-1 Ultra" again shows a distinct advantage in heating capacity at low ambient temperatures, outperforming "Company B" and the "16 SEER" benchmark from -22°F through 38°F.
