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

The Friedrich RD18AY48AJVC is a ducted split system heat pump outdoor unit with a rated cooling capacity of 43,500 BTU/h (about 3.5 tons) and a variable-speed (inverter) compressor running on R-454B refrigerant. ENERGY STAR lists 216 certified indoor-unit pairings for it. In cold weather it still delivers 38,000 BTU/h at 5°F — 79% of its 47°F output, above the 76% median across the 308 models we track (better than 56% 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

  • Efficiency depends on the indoor unit: SEER2 ranges 16–19, so ask which pairing you're quoted

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.
