3.5 Ton Rheem Select 14.3 SEER2 R454B Two Stage Heat Pump System WP14AY42AJ2NA, RH2TY4821STANNJ
This 3.5 ton Rheem Select system steps up to the 21" RH2TY4821STANNJ air handler and its 3/4 HP blower, paired with the WP14AY42AJ2NA two-stage heat pump. Rated 14.3 SEER2 under AHRI #214592591 on R-454B, it gives larger homes the airflow they need at a value price, and it is the first Select size with a 7/8" suction connection.
Is a 3.5 Ton Heat Pump System the Right Size?
Rheem's tested data lists 40,000 BTU/h of cooling, 39,500 BTU/h of heating at 47°F, and 24,800 BTU/h at 17°F. It fits larger homes, open layouts, and hot-climate homes that land between 3 and 4 tons.
Return air and supply duct design have a big effect on comfort and noise at this size, so make sure the ducts can carry the extra airflow before upgrading from a smaller system. Climate, insulation, and occupancy still drive the load, so pair a Manual J calculation with a duct check.
Ideal for: Larger single-family homes, open-concept layouts, homes with large window areas, and replacement of an existing 3.5 ton system.
Need more capacity? Step up to the 4 Ton Rheem Select 14.3 SEER2 R454B Two Stage Heat Pump System WP14AY48AJ2NA, RH2TY4821STANNJ, which uses the same air handler and outdoor cabinet.
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.
