1.5 Ton Rheem Select 14.3 SEER2 R454B Single Stage Heat Pump System WP14AY18AJ1NA, RH2TY2417STANNJ
The only single-stage model in the Rheem Endeavor® Line Select™ Series, the WP14AY18AJ1NA heat pump pairs with the RH2TY2417STANNJ air handler in this 1.5 ton system for simple, budget-friendly heating and cooling on low-GWP R-454B refrigerant. Rated 14.3 SEER2 under AHRI #214568788, it is a practical choice for landlords, condo owners, and homeowners replacing a small system who want a dependable brand at an entry-level price.
Is a 1.5 Ton Heat Pump System the Right Size?
Rheem's tested data rates this match at 17,100 BTU/h of cooling and 16,600 BTU/h of heating at 47°F. That suits compact spaces with lighter loads: condos, apartments, small single-level homes, and additions with their own ductwork.
Single-stage equipment runs at full output whenever it is on, so correct sizing matters even more than with a two-stage system. An oversized unit will short-cycle and leave the air clammy. Insulation, windows, duct condition, and climate all shape the real load, so start with our AC tonnage and BTU calculator and confirm with a Manual J calculation.
Ideal for: Rental units, condos and apartments, small single-family homes, in-law suites, and room additions.
Need more capacity? Step up to the 2 Ton Rheem Select 14.3 SEER2 R454B Two Stage Heat Pump System WP14AY24AJ2NA, RH2TY2417STANNJ, which adds two-stage operation and more capacity with the same air handler.
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.
