Ducted split systemVariable-speed (inverter)ENERGY STAR cold-climateENERGY STAR Most Efficient (some pairings)

The Rheem RD18AY24AJVC is a ducted split system heat pump outdoor unit with a rated cooling capacity of 21,400 BTU/h (about 2 tons) and a variable-speed (inverter) compressor running on R-454B refrigerant. ENERGY STAR lists 77 certified indoor-unit pairings for it. In cold weather it still delivers 18,400 BTU/h at 5°F — 77% of its 47°F output, above the 76% median across the 308 models we track (better than 51% of them). Its HSPF2 of 10 is higher than 77% of models in our database, and its best certified SEER2 of 19 beats 67%.

Our take in 30 seconds

Best for: mixed climates with occasional hard freezes

Strengths

  • Heating efficiency (HSPF2 10) beats 77% of models
  • Variable-speed compressor: quieter, steadier temperatures and better humidity control
  • Uses newer, lower-impact R-454B refrigerant
  • Also sold under 2 other badges, so you can compare more quotes for the same unit

Good to know

  • No notable drawbacks in the certified data.

Same equipment sold under other brands

These listings share the same certifying manufacturer (Rheem Sales Company, Inc.) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.
