Mini Split for 120 sq ft
Choosing a mini split for 120 sq ft typically means targeting a 2,400 to 3,000 BTU range. This light capacity is ideal for slightly larger small rooms where steady airflow matters, but overpowering the space can reduce comfort. Shopping by room size helps you focus on units that match your square footage without overspending on output you don’t need.
