Carrier D5FUHAH36XAK Air Handler 36000 Btu/h 3 Ton R-454B

Product Description

The CARRIER D5FUHAH36XAK is a 3-ton crossover air handler rated at 36,000 BTU/h, designed for residential split-system applications using R-454B refrigerant. Built on a galvanized steel cabinet finished in gray, this unit serves as the indoor section of a split or heat-pump system, circulating conditioned air through the duct system after the refrigerant coil and any supplemental heat strips do their work. At 21.5 inches wide, 58.125 inches tall, and 17.5 inches deep, it fits standard residential closet and utility-room installations. HVAC technicians and installing contractors are the intended trade audience for this equipment.

The D5FUHAH36XAK is positioned in the ICP family of air handlers, which spans the Carrier Corporation brand portfolio including units marketed under the Comfortmaker and Tempstar names. Parts and components are shared across all ICP brands, so a unit received may carry the Comfortmaker or Tempstar label depending on dealership affiliation — performance and construction are identical. This handler suits residential new-construction and replacement projects where a floor-mount or upflow crossover configuration is required and where the system refrigerant circuit has been specified for R-454B.
