DIY 5th Gen Multi-Zone

The MRCOOL® DIY® 5th Generation Multi-Zone system lets you heat and cool multiple rooms from a single outdoor condenser — without requiring an HVAC license, vacuum pump, or professional installer. Each condenser supports 3 to 6 independent zones, all controlled separately via the SmartHVAC app, Amazon Alexa, or Google Assistant. R-454B refrigerant and Quick Connect® technology mean no vacuuming is required at installation.
