The size of a Mitsubishi heat pump depends on factors like square footage, insulation, and climate. For smaller spaces up to 500 sq ft, a small single-zone unit with 6,000-12,000 BTUs may suffice. Larger spaces of 2,000-3,000 sq ft may require a large single-zone unit with 36,000-48,000 BTUs. For even larger areas, multiple units or a multi-zone system may be necessary. Consulting a professional is recommended for precise sizing.
