      9,300 BTU U-shaped window air conditioner with heat

      GREE GJH09BW-A6DRNL1B

      Excellent efficiency for its size: a CEER of 16.1 ranks #3 of 28 10,000 BTU window air conditioners.

      It cools a room of about 300-400 sq ft, draws about 578 watts and costs about $78 a year to run at typical U.S. use and prices.

      A good fit if…

      • You want low bills - its CEER beats 91% of 10,000 BTU window air conditioners.
      • You want a quieter room and a usable window - the window closes into the U, so the compressor sits outside the glass.
      • You want heat in spring and fall - it runs as a heat pump in reverse.
      • You want to plug it into an ordinary outlet - it runs on 115 V.

      Think twice if…

      • You plan to install it alone - at 116 lb it is a two-person job.

      Questions7
      How many square feet does the GREE GJH09BW-A6DRNL1B cool?
      At 9,300 BTU/h it suits a room of about 300 to 400 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 330-440 sq ft; in a very sunny one it shrinks to 270-360 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the GREE GJH09BW-A6DRNL1B use?
      About 578 watts at full power (9,300 BTU/h divided by its CEER of 16.1), which is 5.0 amps at 115 V. That is 89 W less than the typical unit in its class (667 W), or $12 a year cheaper to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 89% of the 28 units in the class.
      Can the GREE GJH09BW-A6DRNL1B run on a standard outlet?
      Yes. It runs on 115 V and draws about 5.0 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.
      What are the dimensions of the GREE GJH09BW-A6DRNL1B, and will it fit my window?
      26" W × 15.3" H × 27.5" D, 116 lb. It is narrower than 4% of its 27 competitors and lighter than 7% of them. The window closes into the U-shaped slot, so measure the opening height as well as the width: you need at least the unit's 26" width between the frame sides.
      Is the GREE GJH09BW-A6DRNL1B U-shaped design an advantage?
      Mostly yes. The sash closes into the unit, so the window stays sealed and daylight comes in, and the compressor is outside the glass, which cuts noise indoors. The trade-off is a window that must slide up and down, and a few extra steps to fit the foam seals.
      How does the GREE GJH09BW-A6DRNL1B heat?
      It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 6 certified units in its class that heat. Heating output is not part of the ENERGY STAR data, so ask the maker for its heating capacity and lowest outdoor temperature before relying on it in winter.
      Is the GREE GJH09BW-A6DRNL1B worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $140 a year to run at 750 hours and 18.0¢/kWh; this one costs about $78, so it saves roughly $62 a year.

      Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
