2 Ton Rheem Select 15.2 SEER2 R454B Central System WA14AY24BJ1NA, RH2TY2417STANNJ
This Rheem Endeavor® Line Select™ system delivers 24,000 BTU/h from the second-design WA14AY24BJ1NA condenser. It's matched with the RH2TY2417STANNJ two-stage-airflow air handler under AHRI certificate #216375606. The "B" design runs on a lower 14 MCA and 20A breaker than the original WA14AY24A. That's helpful when replacing a 2 ton system on an existing circuit. It uses low-GWP R-454B refrigerant with Rheem's PlusOne® Refrigerant Detection System™, suited to starter homes, larger condos and rentals. Optional Rheem electric heat strips add backup heat.
Is a 2 Ton Air Conditioning System the Right Size?
Two tons (24,000 BTU/h) is a common fit for moderate cooling loads. That's often 2-bedroom homes, larger condos and starter homes around 900–1,200 sq. ft. as a general reference. Homes with the same floor plan can need different tonnage depending on orientation and construction.
Before settling on 2 tons, look at attic insulation, the size and direction of your windows, how well the ducts are sealed and how humid the home gets in summer. A Manual J load calculation helps you avoid carrying an oversized system forward from the original install.
Ideal for: Starter homes, 2-bedroom houses, larger condos, rental properties and single-zone additions.

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.

Frequently Asked Questions
What's the difference between the WA14AY24A and WA14AY24B?
This system uses the second-design WA14AY24BJ1NA. Rheem lists it at 10 RLA, 14 MCA and a 20A max breaker with an 82 oz. charge, compared with 12.7 RLA, 17 MCA, 25A and 73 oz. for the WA14AY24A.
How loud is the 2 ton Rheem WA14AY condenser?
Rheem rates the WA14AY24 at 71 dBA weighted sound power, tested to AHRI Standard 270. Its one-piece drawn base pan and fan blade design are part of Rheem's sound-dampening approach.
Which RH2TY airflow stage serves a 2 ton condenser?
Rheem lists the RH2TY2417 at 600 CFM on low and 800 CFM on high nominal airflow. The 800 CFM figure matches Rheem's nominal 400 CFM per ton for a 2 ton system.
Can the RH2TY2417STANNJ be installed horizontally in an attic?
Yes. The RH2TY is 4-way convertible for upflow, downflow, horizontal left and horizontal right. Rheem's manual adds guidance on insulation and condensation for unconditioned spaces.
How long can the line set be on the WA14AY24BJ1NA?
Rheem allows up to 250 ft. equivalent and 200 ft. actual line length. Longer runs may need the accessories listed in Rheem's Long Line Set Guide.
Does buying online affect the Rheem warranty?
Rheem's limited warranty excludes equipment sold via the internet that isn't installed by a trained, qualified HVAC professional. Have a licensed contractor install the system and register it.
