Product Description 

Model: DIYM248HPW01D07    

 

Small Room + Large Space Master Combo — Powered by the 48K Double-Stack DIY System

The MRCOOL DIYM248HPW01D07 delivers elite, whole-home comfort performance using the most powerful DIY condenser MRCOOL makes — the 48K 6-Zone Multi-Zone — paired with two perfectly sized wall air handlers for dramatically different spaces:

✔ 9K Wall Unit — Zone 1 (Small Room Comfort)

Designed for:

• Bedrooms
• Offices
• Guest rooms
• Small enclosed spaces

 

✔ 36K Wall Unit — Zone 2 (Large Space Heating & Cooling

Built for:

• Large living rooms
• Open-concept areas
• Basement living spaces
• Workshops
• Oversized bonus rooms

This bundle provides precision climate control everywhere — from a small, quiet bedroom to a large, high-demand zone — all with true DIY installation.

And with the 48K double-stack condenser, you still have 4 more zones available for future expansion.

 

✔ The perfect “small + huge” two-zone layout

You get:

• Soft, quiet comfort in the 9K room
• Massive airflow & heating power in the 36K room

 

✔ 16ft line sets = perfect for close-range installs

The included 16-foot Quick-Connect line sets are ideal for:

• Back-to-back installations
• Same-wall connections
• Garages, workshops, attics
• Rooms close to the outdoor unit

This reduces install time and gives you a stronger SEO ranking for “short line set” searches.

✔ True DIY system — no vacuum, no gauges, no EPA license

Every line set is pre-charged with R-454B, the 2025+ compliant refrigerant already required by federal regulations.

This puts your store ahead of older R-410A systems still being pushed by competitors.

✔ 48K condenser = 2,000+ sq ft potential

Even with 9K + 36K connected, the remaining 4 ports can be used for:

• Wall mounts
• Ceiling cassettes
• Ducted units
