42,000 BTU

The Mitsubishi MXZ-SM42NAMHZ-U1 is capable of handling a total of 42,000 BTU, which is typically the same or greater than the total BTU count across all air handlers paired with this unit. Certified pairings may have a higher BTU count total than this condenser's rating, but exceeding the rating can potentially lower the speed at which the unit heats and cools, and limit the functional outputs of each air handler when running simultaneously.

Warranty

Mitsubishi provides a 5-year parts and 7-year compressor warranty on all their products. By registering the unit online following state and local installation codes, the warranty is upgraded to a 10-year parts and compressor warranty.

Required Equipment

The MXZ-SM42NAMHZ-U1 is designed with one set of line set ports, allowing it to support a higher BTU output than units with multiple sets. Therefore, at least one branch box is required for it to connect to multiple air handlers. Basic installation equipment such as air handlers, controllers, and other accessories are available at an additional cost.

Enhanced Comfort

The MXZ-SM42NAMHZ-U1 comes with a variable speed compressor that provides more precise adjustments to covered spaces with compatible air handlers. This feature improves electrical efficiency by ramping the compressor up and down based on the needs of the unit's air handlers. It also provides a more stable temperature output from connected air handlers, delivering superior comfort.

Intelligent Control

Compatible air handlers can be controlled using any Mitsubishi-brand thermostat or adapter. The Kumo cloud WiFi adapter is the most convenient option, allowing access to each air handler from anywhere with an Internet connection. However, one thermostat or adapter is required per indoor air handler for most applications.
