3 Ton Rheem 16 SEER2 R454B Side Discharge Heat Pump System RD16AY36AJVCA, RH2TY3617STANNJ
Three tons of inverter-driven heating and cooling from an outdoor cabinet that stands 31.8 inches tall and weighs 146 pounds — roughly half the weight of a conventional 3 ton condenser. The RD16AY36AJVCA is also the quietest unit in the Classic Plus range at a 58 dBA rating, matched here to the RH2TY3617STANNJ two-stage air handler in a 17.5-inch cabinet. Thirty-six thousand BTU on low-GWP R-454B refrigerant at 16 SEER2, certified under AHRI reference 217349868.
Is a 3 Ton Heat Pump the Right Size?
Three tons produces 36,000 BTU per hour and covers roughly 1,500 to 1,800 square feet in a hot climate. It is the most-installed residential capacity in the country and the size most straight replacements land on. As a heat pump the same equipment handles winter, with the inverter compressor modulating to about 1.35 tons during mild weather instead of short-cycling.
This particular pairing is the one to reach for when the outdoor unit has to live somewhere awkward. At 31.8 inches tall it clears under most windows, sits below fence-line in many HOA setups, and is light enough at 146 pounds for a two-person set without equipment. Combined with the 58 dBA rating — the lowest in this group — it is the configuration that causes the fewest complaints when the condenser ends up near a patio, bedroom wall, or neighbor's property line.
Ideal for: Three-bedroom single-story homes, 1990s and 2000s tract construction, HOA communities with height or screening rules, and installations adjacent to patios or bedroom walls.

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

The 3 ton RD16AY shares its exact cabinet dimensions with the 2 ton model — same 19.8 inch width, same 40.4 inch depth, same 31.8 inch height — and adds only 18 pounds. That makes the two interchangeable from a site-planning standpoint, which is useful when the load calculation is still pending but the pad location has to be committed.

Frequently Asked Questions
Why is the 3 ton rated 16 SEER2 when the 2 ton is 17?
Each matched pair is certified independently. The 2 and 5 ton combinations in this series reach 17 SEER2 while the 3 and 4 ton certify at 16. All four use the same inverter compressor architecture, and all four exceed the federal minimum for the Southeast region.
Will this fit behind a standard HOA screen or fence?
At 31.8 inches tall it clears most 36-inch and 42-inch screening requirements with room to spare. Verify the discharge-side clearance requirement in the RD16AY installation instructions, since side-discharge units need unobstructed space in front of the fan rather than above it.
How heavy is this compared to a conventional 3 ton condenser?
Roughly 146 pounds operating weight. Conventional top-discharge 3 ton condensers commonly run 200 pounds or more. The reduction comes from the 7mm coil design and the compact cabinet, and it simplifies rooftop, balcony, and elevated-platform installations.
Is the air handler the same one used on 2.5 ton systems?
Yes. The RH2TY3617STANNJ serves both 2.5 and 3 ton applications on a 1/2 HP constant torque motor. That shared coverage is why it is the highest-volume indoor unit in the RH2TY family.
Does a quieter rating actually matter day to day?
Three decibels is roughly a halving of measured sound power, so the difference between 58 and 61 dBA is audible rather than theoretical. It matters most when the unit sits within about fifteen feet of a bedroom window or an outdoor living area.
Where can I compare this against other Rheem systems?
Our Rheem catalog covers the full equipment line, and complete split systems lists every matched indoor and outdoor combination we stock, including the higher-efficiency Prestige series units.
