1.5 Ton Rheem 15.2 SEER2 R454B Central System RA14AY18AJ1NA, RH2TY2417STANNJ

1.5 Ton Rheem 15.2 SEER2 R454B Central System RA14AY18AJ1NA, RH2TY2417STANNJ

This 1.5 ton Rheem Endeavor Line matched system pairs the RA14AY18AJ1NA outdoor condenser with the RH2TY2417STANNJ two-stage air handler to deliver 18,000 BTU of cooling at 15.2 SEER2 on low-GWP R-454B refrigerant. It is the smallest capacity in the RA14AY lineup and the one most often specified for condominiums, garage conversions, room additions, and compact single-story homes where a larger system would short-cycle. The 17.5-inch air handler cabinet slips into the narrow utility closets common in older condo and apartment construction, and the factory-matched pairing carries AHRI certificate 215232472.

Is a 1.5 Ton Refrigeration System the Right Size?

A 1.5 ton system produces 18,000 BTU per hour of cooling. In most of the Southeast that translates to roughly 600 to 900 square feet of conditioned living space, though square footage alone is never the whole answer. This capacity is generally chosen for a one or two bedroom condo, a mother-in-law suite, a finished garage, or an addition served by its own dedicated duct run rather than tied into an existing trunk line.

Ceiling height, window area and orientation, attic insulation depth, duct location, shading, occupancy, and local design temperature all move the load calculation. Oversizing a small zone is a common mistake: a system with too much capacity satisfies the thermostat before it has run long enough to pull humidity out of the air, which leaves the space feeling cold and clammy. A Manual J load calculation is the reliable way to confirm 1.5 tons is correct before committing.

Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, duct design, window area, ceiling height, occupancy, and local design conditions.

What’s Included

Both halves of this package ship as a factory-matched, AHRI-certified pair. The RA14AY18AJ1NA and the RH2TY2417STANNJ each carry Rheem’s PlusOne Refrigerant Detection System, so the A2L sensor and mitigation board are already integrated rather than field-added. Electric heat kits, thermostats, and line sets are ordered separately to suit the installation.
