Check price on AmazonHow we picked
We compared window air conditioners in the 5,000 to 8,000 BTU bedroom range using published specifications only. No unit was handled. We prioritized the maker's listed noise figure, room coverage in square feet, control options, and efficiency features such as inverter compressors and ENERGY STAR certification. A product that states more relevant specs wins a tie. For more on how noise is listed, see window AC noise and our bedroom cooling guide.
Why noise matters in a bedroom
A window air conditioner sits in the room with you, so its published noise figure is often the first spec to check for a bedroom. The units above range from 37 dB to 52 dB in the maker's listings. Lower figures generally mean a less intrusive hum overnight, though the actual sound also depends on installation and fan speed. Inverter models often hold a lower steady level instead of cycling loudly.
BTU and room size for bedrooms
For a bedroom, match the unit's stated BTU figure to the maker's square footage coverage. A 5,000 BTU unit typically covers up to 150 sq ft, a 6,000 BTU unit up to 250 sq ft, and an 8,000 BTU unit up to 350 sq ft. An oversized unit can cool the air before removing enough moisture, leaving the room feeling damp. See choosing BTU for room size for the full sizing logic.
Controls and smart features
Remote control is useful from bed, and app or voice control lets you adjust settings without reaching the unit. Several picks above add Wi-Fi, app, and voice support, while basic 5,000 BTU models may rely on touch or push buttons only. Check whether the control panel can be dimmed or muted if the display light bothers you at night; some maker manuals describe a light off function.
Modes that help overnight
Sleep mode, where listed, adjusts the set temperature during the night, and eco or energy saver mode cycles the fan with the compressor to reduce runtime. Timer functions can switch the unit off before morning or on before you return. Dry mode removes moisture on humid nights without heavy cooling. Not every bedroom unit includes all of these, so compare the listed special features.
Efficiency and ENERGY STAR
Seasonal efficiency figures and ENERGY STAR certification point to lower electricity use over a cooling season. In this range, listed seasonal efficiency figures vary from about 11 to 15.1, with inverter and ENERGY STAR models at the higher end. A higher figure means more cooling per watt; these listings label it SEER, while the federal rating for room units is CEER. See ENERGY STAR room AC criteria for what the badge requires.

Questions people ask
What BTU window air conditioner is right for a bedroom?
Match the maker's square footage figure to your room. A 5,000 BTU unit usually covers up to 150 sq ft, a 6,000 BTU unit up to 250 sq ft, and an 8,000 BTU unit up to 350 sq ft. ENERGY STAR adds 10 percent to the capacity for a very sunny room and suggests a larger unit for ceilings above 8 feet.
Is a 5,000 BTU window unit enough for a bedroom?
It can be, if the bedroom is about 150 sq ft or smaller and is not unusually sunny or poorly insulated. For larger bedrooms, the 6,000 BTU picks list 250 sq ft and the 8,000 BTU picks list 350 sq ft.
Are inverter window air conditioners quieter?
Not always. ENERGY STAR says a variable speed compressor lets a room AC cool quietly, and the Hisense Inverter 8,000 BTU lists 37 dB and the Frigidaire 8,000 BTU Inverter 41 dB, but the Midea Inverter 8,000 BTU Window lists 50 dB. Compare each listed figure.
Is Wi-Fi or app control necessary in a bedroom AC?
Not necessarily, but app or voice control lets you adjust settings from bed or away from home. If you only need basic cooling, a remote or touch control model works fine. The LG LW6024RSMX 6,000 BTU and Midea Inverter 8,000 BTU Window add smart controls.
What is sleep mode on a window air conditioner?
It depends on the maker. On the Midea MAW06R1WWT, sleep mode raises the set temperature by 2°F after 30 minutes and by another 2°F later, holds it for 7 hours, then returns to the original setting.
