2.5 Ton Rheem Select 14.3 SEER2 R454B Single Stage Central System WSA14AY30AJ1NA, RH1AY3617STANNJ
This Rheem Endeavor® Line Select™ Series iC system is the largest small footprint match with the RH1AY air handler. It pairs the WSA14AY30AJ1NA condenser with the RH1AY3617STANNJ single-stage-airflow air handler, AHRI certified at 14.3 SEER2 (#217486292). The condenser delivers 30,000 BTU/h from a 27.63" x 27.63" base and is the quietest WSA14AY at 74 dBA. It uses low-GWP R-454B with Rheem's PlusOne® Refrigerant Detection System™. It's cooling only, with Rheem electric heat strips up to 15 kW offered.
Is a 2.5 Ton Air Conditioning System the Right Size?
A 2.5 ton system provides 30,000 BTU/h of nominal cooling. It's commonly used in 2- to 3-bedroom homes around 1,200–1,500 sq. ft. as a rough guide, though climate and construction shift that range.
West-facing glass, vaulted ceilings and leaky attic ducts can push a home toward 3 tons, while a tight home may need less. A Manual J load calculation gives a reliable answer before you buy.
Ideal for: 2- to 3-bedroom homes, townhomes and infill houses with small pads.
Need more capacity? For more capacity, see the 3 Ton Rheem Select 14.3 SEER2 R454B Single Stage Central System WA14AY36AJ1NA, RH1AY3617STANNJ, which uses the same air handler.
Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.
