Elevate your home comfort with the MRCOOL 48K 6‑Zone DIY Mini Split Bundle With 9K + 36K Air Handlers (16ft Line Sets) — a powerful, flexible HVAC system designed for both small and large living spaces with true do‑it‑yourself installation ease. This bundle pairs MRCOOL’s robust 48,000 BTU 6‑Zone Multi‑Zone condenser with a 9K BTU wall mount and a 36K BTU wall mount air handler for targeted temperature control throughout your home. With up to six zones available for expansion, this system gives you the freedom to customize comfort room by room — from cozy bedrooms to open living areas — without the need for professional refrigerant tools, wiring gauges, or vacuum pumps.

Delight in energy‑efficient performance backed by a 21.8 SEER2 rating and the low‑global‑warming potential refrigerant R‑454B already pre‑charged in the line sets. The outdoor condenser unit is engineered to handle homes up to ~2,000 sq. ft., while providing whisper‑quiet operation and smart connectivity features compatible with the MRCOOL SmartHVAC® app, Amazon Alexa, and Google Assistant. Whether you’re keeping a guest room comfortably cool or warming a large living space in winter, this bundle delivers consistent, reliable performance.

The included 16‑foot Quick‑Connect line sets are ideal for installations with the condenser close to indoor units — perfect for back‑to‑back rooms or spaces near the outdoor unit. These pre‑charged, factory‑sealed line sets simplify the installation process and eliminate the need for additional tools or professional refrigerant handling, making this system a top pick for experienced DIYers and first‑time installers alike.

Backed by MRCOOL’s commitment to innovation and quality, this mini split system delivers advanced inverter technology, efficient climate control, and scalable expansion potential. With four unused ports remaining on the condenser, you’re ready to add additional zones as your comfort needs grow.
