The Mitsubishi MFZ-KJ18NA / MUFZ-KJ18NAHZ is a floor mounted single-zone mini split. With its high 21 SEER efficiency rating and its 18,000 BTU output, the MFZ-KJ18NA / MUFZ-KJ18NAHZ is a good option for any installation where a low-wall installation is required, as it only needs to be 3” off of the floor.
The Mitsubishi MFZ-KJ18NA / MUFZ-KJ18NAHZ can be used to heat and cool a medium-sized room in ideal climates, with its output of 18,000 BTU. The unit’s efficiency is rated at 21 SEER, saving you money over many other brands due to its high efficiency.
Mitsubishi provides a 5 year parts and 7 year compressor warranty from the factory. When the unit is installed following your state and local codes and is registered online through the manufacturer, the warranty is upgraded to a 10 year parts and compressor warranty.
The Mitsubishi MFZ-KJ18NA / MUFZ-KJ18NAHZ is engineered with automatic adjustments to keep the room’s temperature at the operator’s desired setting, keeping you more comfortable in the space you are trying to heat and cool. With Mitsubishi’s optional Kumo Cloud Adapter, found here, this unit can be controlled from anywhere that you have Internet access—from across town at work to across the world on vacation—bringing ease of control to Mitsubishi’s enhanced comfort systems.
The Mitsubishi MFZ-KJ18NA / MUFZ-KJ18NAHZ’s air handler is manufactured as a slim, low-clearance system, with a bottom clearance of only 3” since the system is designed to have a top output. This small form factor and clearance allows the unit to be installed for more applications, all the while still able to easily heat and cool the room in which it is installed.
