Is a 2 Ton Air Conditioning System the Right Size?
Two tons (24,000 BTU/h) is common in 1- and 2-bedroom apartments and condos around 900–1,200 sq. ft. as a general reference.
Corner units, top floors and large sliding doors raise the load. A Manual J load calculation is the best way to confirm 2 tons before replacing an existing wall mount system.
Ideal for: 1- and 2-bedroom apartments, condos and townhomes replacing an existing wall mount air handler.

Frequently Asked Questions
What do the B05 and B08 endings on the RF1PY model mean?
They identify the factory-installed breakered heater: B05 is 5 kW and B08 is 8 kW. A "417" ending means a factory float switch is also included.
Can the RF1PY2421STANSJ be installed horizontally?
No. Rheem configures all RF1PY units for vertical upflow only. They can be set up for a front or bottom return.

Rheem lists it at 21.5" wide, 36" tall and 17" deep, with an 80 lb unit weight. It's built to fit typical apartment and condo closets.
What filter does the RF1PY2421STANSJ use?
Rheem lists a 20" x 20" x 1" filter for the 21" RF1PY cabinet. Rheem also requires 24" of clearance in front of the unit for filter and coil service.
How does the RF1PY compare to the RF2TY wall mount air handler?
The RF1PY uses a two-speed PSC motor with single-stage airflow. The RF2TY adds a five-speed constant torque motor and two-stage airflow, which lifts this match to 15.2 SEER2. See the RA14AY24BJ1NA, RF2TY2421STANSJ system.
