AOU24RLXFZH Fujitsu Outdoor Unit/Heat Pump 20 SEER


Fujitsu Ductless Mini Split

AOU24RLXFZH Outdoor Heat Pump 1.5 Ton 25,000 BTU 


AOU24RLXFZH Function 

The Fujitsu AOU24RLXFZH outdoor heat pump for a mini split system is a quiet and slim outdoor heat pump that fits perfectly out of the way and is small enough to cause no intrusion. The Aesthetic, minimalist design delivers powerful cooling abilities while at the same time blending in to any outdoor environment. 

AOU24RLXFZH High Performance Low-Ambient Heating 

The RLS3 ductless mini split models have a larger heat exchanger and high capacity compressor which offers improved low temperature heating capacities. The RLS3 ductless mini split models can operate down to -5F.  The RLXFZH models can heat down to -15F. 

AOU24RLXFZH World Class Performance 

Since ductless mini splits have little to no ducting, they forego those energy losses typically associated central forced-air systems. Duct losses can easily account for more than 30% of energy consumption, especially if the ducts are not sealed tight or in an unconditioned space such as an attic or crawlspace. 

AOU24RLXFZH Inverter Technology 

Through  advanced technology, Inverter air conditioners are more economical to operate and quieter to run than conventional units. They can handle greater extremes in temperature, are smoother and more stable in operation, and reach the desired temperature more quickly than conventional air conditioners.

The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 30% more operating efficiency than conventional models and therefore, is much less expensive to run.     



The Extra Low Temperature Heating ductless mini split series features outdoor condensing units engineered to operate down to -15F, lower than any other ductless mini-split available today.
