1.5 Ton Rheem 15.2 SEER2 R454B Two Stage Heat Pump System RP15AY18AJ2NA, RH2TY2417STANNJ
This Rheem Endeavor® Line Classic Plus® system pairs the RP15AY18AJ2NA two-stage heat pump with the RH2TY2417STANNJ multipoise air handler for 15.2 SEER2 heating and cooling on low-GWP R-454B refrigerant. Certified under AHRI #215486995, it is the smallest system in the RP15AY series and brings two-stage comfort, normally found in larger homes, to condos, small houses, and additions where a single-stage unit would cycle on and off constantly.
Is a 1.5 Ton Heat Pump System the Right Size?
At a nominal 1.5 tons, this system is rated by Rheem at 17,100 BTU/h of cooling and 17,100 BTU/h of heating at 47°F. That fits compact floor plans, well-sealed newer construction, and single-level units with modest window area. Because the compressor can run on low stage, it handles mild days without overshooting the thermostat.
The right size still depends on the house: insulation, window orientation, duct leakage, ceiling height, and local climate all change the real load. If you are replacing an older system, do not assume the same tonnage is correct. Start with our AC tonnage and BTU calculator and confirm with a Manual J load calculation.
Ideal for: Condos and apartments, small single-family homes, in-law suites, finished bonus rooms, and additions on their own duct system.
Need more capacity? Step up to the 2 Ton Rheem 15.2 SEER2 R454B Two Stage Heat Pump System RP15AY24AJ2NA, RH2TY2417STANNJ, which shares the same air handler and outdoor cabinet size.
Recommended system sizes are general guidelines only. Actual heating and cooling requirements depend on insulation, climate, windows, ductwork, ceiling height, and occupancy. A Manual J load calculation is the best way to confirm sizing. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Rheem's RH2TY2417STANNJ covers both the 1.5 and 2 ton sizes, and here its two-stage constant torque blower is matched to the 1.5 ton outdoor unit so airflow steps up and down with the compressor. The outdoor unit ships with 83 oz of R-454B, enough for 15 feet of line, and works with a 3/4" x 3/8" copper line set. Add one of our Rheem heat strips (5, 8, or 10 kW on this listing) for backup heat and a two-stage heat pump thermostat to complete the system.

Frequently Asked Questions
What size home fits the 1.5 ton RP15AY18AJ2NA two-stage system?
It suits homes and spaces with an 18,000 BTU/h nominal load, such as condos, small houses, and additions. A Manual J load calculation is the best way to confirm the fit.
Why is a 2 ton RH2TY2417STANNJ air handler included with a 1.5 ton heat pump?
The RH2TY2417STANNJ is Rheem's air handler for both 1.5 and 2 ton systems. Its airflow is set for the 1.5 ton outdoor unit, and the pair is certified together under AHRI #215486995.
What does two-stage operation mean for a small home?
The compressor runs on low stage most of the time and only switches to high stage on the hottest or coldest days. That means longer, quieter cycles, steadier temperatures, and better humidity removal than a single-stage unit.
What thermostat do I need for a two-stage heat pump?
You need a thermostat that supports two compressor stages (Y1 and Y2) plus auxiliary heat. Options on this listing include the Honeywell T6 Pro 3H/2C, Honeywell T10 Pro, ecobee Smart, and Nest Learning thermostats.
How much heating does the 1.5 ton system deliver in cold weather?
Rheem rates this match at 17,100 BTU/h of heating at 47°F and 10,000 BTU/h at 17°F. A heat strip provides supplemental heat when outdoor temperatures drop.
What breaker size does the RP15AY18AJ2NA require?
Rheem lists a 13 A minimum circuit ampacity and a 20 A maximum overcurrent protection, using an HACR-type breaker or fuse. The air handler and heat strip are on a separate circuit.
