3 Ton Rheem Select 15.2 SEER2 R454B Central System WA14AY36AJ1NA, RH2TY3617STANNJ
This Rheem Endeavor® Line Select™ system covers the most common residential size. It pairs the 36,000 BTU/h WA14AY36AJ1NA condenser with the RH2TY3617STANNJ air handler at 15.2 SEER2 (AHRI #215232532). It's the first WA14AY size with a two-row outdoor coil, which adds surface area in the same 33.66" cabinet footprint as the 2 and 2.5 ton models. It suits homeowners replacing an original 3 ton system who want R-454B, PlusOne® leak detection and a compact 17.5" air handler that fits most existing closets. Heat strip options go up to 15 kW.
Is a 3 Ton Air Conditioning System the Right Size?
Three tons (36,000 BTU/h) typically serves mid-size homes, often around 1,500–1,800 sq. ft. as a loose rule of thumb. It's also the size many homes were originally built with, so replacements are common. Still, it's worth confirming the load if the home has been upgraded.
New windows, attic insulation or sealed ducts can lower the load, while additions and converted garages raise it. Two-story homes and large west-facing glass tend to need the full 3 tons. A Manual J calculation keeps the replacement right-sized.
Ideal for: Mid-size 3–4 bedroom homes, two-story homes with moderate loads and original 3 ton system replacements.

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 changes between the 2.5 ton and 3 ton WA14AY?
The WA14AY36AJ1NA adds a second outdoor coil row in the same 33.66" cabinet, carries 116 oz. of R-454B versus 73 oz., and draws 18 MCA with a 30A max breaker.
What size is the RH2TY3617STANNJ air handler?
Rheem lists it at 17.5" wide and 42.5" tall, with a 96 lb unit weight. Its 3/8" liquid and 3/4" vapor sweat connections match the WA14AY36.
Can this 3 ton system use 15 kW of electric heat?
Yes. We offer heat kits up to 15 kW for this system, and Rheem's airflow limits allow up to 18 kW with a 3 ton RH2TY application.
Is the 3 ton WA14AY louder than the smaller sizes?
No. Rheem rates the WA14AY36 at 71 dBA, the same as the 2 and 2.5 ton models and only 1 dBA above the 1.5 ton.
Can the RH2TY3617STANNJ go in an attic or other unconditioned space?
Yes, with care. Rheem's manual warns that cabinets sweat more in unconditioned spaces and gives extra guidance for those installs. Leave at least 24" in front for access.
Does the WA14AY36 need a crankcase heater?
It isn't factory installed on the 3 ton. Rheem lists the 44-101884-08 crankcase heater as an accessory and recommends one when the low ambient kit is used.
