3 Ton Rheem 14.3 SEER2 R454B Single Stage Central System RA14AY36AJ1NA, RH1AY3617STANNJ
This 3 ton Rheem Endeavor® Line Classic® system pairs the RA14AY36AJ1NA condenser with the RH1AY3617STANNJ single-stage-airflow air handler, AHRI certified at 14.3 SEER2 (#217232212). It's one of the most popular residential sizes, delivering 36,000 BTU/h on low-GWP R-454B refrigerant. The RA14AY36 keeps a low 25" profile, and the air handler includes Rheem's PlusOne® Refrigerant Detection System™. It's cooling only, with Rheem electric heat strips up to 15 kW offered.
Is a 3 Ton Air Conditioning System the Right Size?
A 3 ton system provides 36,000 BTU/h of nominal cooling. It's often used in 3-bedroom homes around 1,500–1,800 sq. ft. as a general guide. Hot, humid climates and homes with lots of glass may need more capacity for the same space.
At 3 tons, return air and duct sizing matter as much as the equipment. Undersized returns can starve the air handler of airflow. Pair a Manual J load calculation with a quick duct check to be sure the system performs as rated.
Ideal for: 3-bedroom single-family homes, larger townhomes and rental homes.
Need more capacity? Step up to the 3.5 Ton Rheem 14.3 SEER2 R454B Single Stage Central System RA14AY42AJ1NA, RH1AY4821STANNJ for a larger load.
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.
