2.5 Ton Rheem 15.2 SEER2 R454B Heat Pump Short Apartment/Condo Type System RP14AY30AJ2NA, RB2TY3621STANMJB
This is the efficiency pick of Rheem's short apartment/condo heat pump lineup. It matches the RP14AY30AJ2NA two-stage R-454B heat pump with the 21" wide RB2TY3621STANMJB low-boy air handler and is listed at 15.2 SEER2 (AHRI #216010781). It provides 30,000 BTU of nominal heating and cooling, and the air handler stands about 35 inches tall. That suits larger condos and apartments where the mechanical closet is short but the load is too big for a 2 ton system. The air handler comes with a 1/2 HP constant-torque ECM blower and factory electric heat in 5, 7 or 10 kW.
Is a 2.5 Ton Heat Pump System the Right Size?
A 2.5 ton system serves heating and cooling loads around 30,000 BTU per hour. Typical examples are two-bedroom condos, open living areas with sliding glass doors, and top-floor units that soak up roof heat. This pairing is a step up from a 2 ton system without jumping to 3 tons, which could short-cycle and leave the unit humid in mild weather.
Because the RP14AY30AJ2NA is a two-stage heat pump, it covers a wider range of conditions than a single-stage unit. Low stage handles the mild days and high stage takes over during peak heat and cold. Confirm your load with the heat pump sizing calculator, considering insulation, exposure, windows and occupancy.
Ideal for: Two-bedroom condos, larger apartments with short closets, top-floor and corner units, and efficiency-minded replacement of 2.5 ton low-boy air handlers.
Need more capacity? Step up to the 3 Ton Rheem 14.3 SEER2 R454B Heat Pump Short Apartment/Condo Type System RP14AY36AJ2NA, RB2TY3621STANMJB, which uses the same 21" low-boy air handler.
Recommended system sizes are general guidelines only. Actual requirements depend on climate, insulation, unit location within the building, window exposure, occupancy, and installation conditions. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Who is the 2.5 ton RP14AY30AJ2NA short system best suited for?
Owners of two-bedroom condos and larger apartments with a load near 30,000 BTU and a mechanical closet too short for a full-height air handler. Of the three short systems, it is also the efficiency choice, listed at 15.2 SEER2.
Why does the 2.5 ton system use the RB2TY3621STANMJB air handler?
Rheem builds the 21" RB2TY3621 cabinet to serve both 2.5 and 3 ton outdoor units. Its field-selectable ECM airflow is set to match the RP14AY30AJ2NA, so one air handler size covers both capacities without changing the closet layout.
How does the RP14AY30AJ2NA two-stage compressor help in a condo?
Most of the time the compressor runs on low stage. That gives longer, quieter cycles that even out temperatures between rooms and remove more humidity. High stage only kicks in on the hottest and coldest days.
What filter size fits the RB2TY3621STANMJB?
The 21" cabinet takes a 19.75" x 21" filter, Rheem replacement part 54-23217-03. Check it regularly, because a clogged filter cuts airflow and reduces both efficiency and heating output.
How big and heavy is the RP14AY30AJ2NA outdoor unit?
The RP14AY30AJ2NA is 27" tall with a 33-3/4" x 33-3/4" base and an operating weight of 189 lbs. Use those numbers when planning a balcony, rooftop or ground-pad location and the equipment you'll need to lift it into place.
Does the RB2TY3621STANMJB detect refrigerant leaks?
Yes. It includes Rheem's PlusOne® Refrigerant Detection System™ with a factory-installed A2L sensor and mitigation board. If excess R-454B is detected, the system automatically pauses outdoor unit operation. It works with any 24V thermostat.
