MFZ-KJ Floor-Mounted Indoor Unit
The MFZ-KJ Floor-Mounted Indoor Unit evenly heats and cools a single zone of your home, or you can invest in multiple units for whole-home heating and cooling. A single unit is ideal for open-plan spaces, additions, garages, and parts of your home not connected to your central HVAC system. Or, multiple units can work together as your home’s primary HVAC solution.
The floor-mounted design means this unit sits close to the floor, near the bottom of your wall. It can be partially recessed to ensure a seamless look. Wondering if this is the right indoor unit for you? Take a look at its specs and features.
Features of the MFZ-KJ Floor-Mounted Indoor Unit
The MFZ-KJ Floor-Mounted Indoor Unit boasts features that help reduce your heating and cooling bills while making your home as comfortable as possible. If you’re tired of inefficient, uneven heating and cooling, you’ll love these great features.
Multi-Flow Vanes
Multi-vane technology allows warm air to flow in both an upward and downward direction to improve efficiency and quickly heat up cold spaces.
Fast Heating Ultra Start
For low indoor temperature starts, the rapid heating technology of this unit angles the multi-vane downward to direct warm air into the return. Then, the air is reheated before being released through the top portion of the multi-flow vane.
Econo Cool
The Econo Cool feature uses fans to strategically improve airflow through the zone. When you select this setting, the thermostat increases by a few degrees, reducing the energy used by the system. But the airflow ensures that the room’s occupants stay just as comfortable as they were.
Nano Platinum Filter
Using a platinum catalyst, this filter absorbs cells at a molecular level. It improves your indoor air quality by removing unpleasant odors, viruses, bacteria, and pollutants from the air.
Swing Fan
The swing fan feature ensures that the air from the MFZ-KJ Floor-Mounted Indoor Unit reaches every corner of your area. Enjoy even heating through your whole zone thanks to the swing fan.
Powerful Mode
When you engage Powerful Mode, this floor-mounted unit kicks into high gear. A perfect option when you want to quickly bring a room to temperature, this mode shuts off automatically after a while to preserve efficiency.
