MRCOOL DIYM236HPW02D00 – 36k 5th Gen DIY Multi-Zone Bundle with 9K + 18K & 16ft Line Sets
The MRCOOL DIYM236HPW02D00 bundle is a 5th Generation multi-zone DIY system built around the DIY-MULTI5-36HP230D-O 36,000 BTU condenser, paired with a 9,000 BTU wall-mount air handler, an 18,000 BTU wall-mount air handler, and two 16-foot R-454B Quick-Connect® line sets. It’s a perfect configuration for homeowners who want true DIY installation, quiet comfort, and room-by-room control without paying HVAC labor rates.
Use the 9K indoor unit for a bedroom, office, or flex room up to about 400 sq. ft., and the 18K indoor unit to handle a medium-to-large space up to about 800 sq. ft. The 36k multi-zone condenser can support up to 5 total zones, so you can always add more indoor units later as your needs grow.
Because every major refrigerant connection is handled by pre-charged R-454B Quick-Connect® line sets, installation is vacuum-free and gauge-free—exactly what serious DIYers want.
