Experience efficient, customizable comfort without the need for professional HVAC installation with the MRCOOL DIY® 5th Gen Multi‑Zone 4‑Zone 48,000 BTU Mini‑Split System. This advanced ductless heat pump system pairs a powerful 48,000 BTU multi‑zone condenser with a thoughtfully balanced set of two 6,000 BTU, one 9,000 BTU, and one 12,000 BTU indoor air handlers—perfect for homes with a mix of bedrooms, offices, medium‑sized living spaces, and more.

Backed by advanced inverter technology, Gold Fin® corrosion protection, and smart home compatibility, it delivers quiet, efficient performance year‑round.
