Control temps in extra-large spaces with quiet comfort, dual zones, and a simple install that skips HVAC pros.
The MRCOOL DIY Multi-Zone 48,000 BTU Mini Split gives you serious climate control for large homes or open-plan areas—without paying a pro to install it. This 2-zone setup includes a 12K BTU air handler (up to 550 sq ft) and a 36K BTU air handler (up to 1,650 sq ft), powered by a high-capacity 48K BTU condenser.
Designed for simple DIY installation, this system is perfect for anyone upgrading their HVAC setup with smart controls, high efficiency, and the ability to heat, cool, or dehumidify through every season.
Note: Pricing doesn't include the Line Sets. Available to purchase separately.
Coverage Area
Please refer to this coverage chart to determine the required BTUs for the area you wish to cool or heat.
- Square Feet: 180-375 | BTU = 9K
- Square Feet: 376-500 | BTU = 12K
- Square Feet: 501-750 | BTU = 18K
- Square Feet: 751-1,000 | BTU = 24K
- Square Feet: 1,001-1,500 | BTU = 36K
Note about condenser sizes versus total air handler capacity: The total capacity of the combined air handlers may exceed the capacity of the condenser in certain configurations. While this provides more flexibility in your setup, you will need to either shut off one of your air handlers (zones) or reduce the output of all zones.
