  • Sizing Chart

    Air Handler BTU Coverage Area (sq. ft.)
    9,000 BTU 375 sq. ft.
    12,000 BTU 550 sq. ft.
    18,000 BTU 800 sq. ft.
    24,000 BTU 1,050 sq. ft.
    36,000 BTU 1,550 sq. ft.

    Understanding your system:

    • Condenser's BTU affects indoor air handlers.
    • For instance, an 18,000 BTU condenser will limit two 12,000 BTU handlers to 9,000 BTU each when used simultaneously.
    • Choose a higher BTU condenser for full power across all handlers.
