It's one of the most affordable ways into a 3 ton Rheem R-454B system, with a low 25.17" condenser profile and a fully louvered steel cabinet. 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.
At 3 tons, return air and duct sizing matter as much as the equipment. Pair a Manual J load calculation with a duct check to make sure the system performs as rated.
Ideal for: 3-bedroom homes, rentals and budget-focused replacements.
Need more capacity? Step up to the 3.5 Ton Rheem Select 14.3 SEER2 R454B Single Stage Central System WA14AY42AJ1NA, 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.
