Verdict: The Hisense HLAW0825TW is a well-equipped 8,000 BTU inverter window air conditioner for bedrooms and offices up to about 350 square feet. Its compact indoor profile, Wi-Fi controls, supplied installation bracket and claimed low-noise design are compelling. However, the exact model lacks an independent published noise test, so the widely quoted 43 dB figure comes from an older related Hisense model and should not be treated as a direct HLAW0825TW result.
What is the Hisense HLAW0825TW?
The HLAW0825TW is Hisense’s current 8,000 BTU UltraSlim smart inverter window air conditioner. Costco lists it for rooms up to 350 square feet, with Energy Star certification, Wi-Fi control, a timer, washable filter, four-way airflow and three fan speeds.

Hisense introduced the UltraSlim line on March 21, 2025, describing a low indoor profile, advanced cross-flow fan, optimized air profile, large louvers and an updated heat exchanger. Those are manufacturer claims, not independent test findings. Hisense also says its supplied bracket uses adjustable sliding arms, while the side curtains seal gaps and block light.

Is the Hisense UltraSlim actually quiet?
Hisense markets the UltraSlim as “Ultra-Quiet Operation,” attributing lower noise to inverter technology and sound barriers. The manufacturer says its advanced inverter system helps the compressor vary output instead of repeatedly switching fully on and off.

There is no direct independent laboratory or hands-on noise measurement for the HLAW0825TW in the available evidence. The best directional data comes from Tom’s Guide’s August 4, 2022 review of the related AW0822TW1W. That reviewer measured 43 dB from six feet away in ultra-quiet mode and 55 dB on high, and wrote: “I could barely believe my ears at how quiet the Hisense A/C was; in its ultra-quiet mode, I heard more noise coming from outside the window than I did from the air conditioner.”
Tom’s Guide considered that older model among the quietest smart window air conditioners. Because the AW0822TW1W is not the HLAW0825TW, those readings indicate what Hisense’s inverter platform may deliver, not a guaranteed result for this newer unit. Room acoustics, compressor speed, window sealing and outdoor traffic will change what you hear.

What room size can the Hisense HLAW0825TW cool?
Costco’s stated maximum is 350 square feet. That is a reasonable target for a bedroom, home office or similarly enclosed room with average insulation and moderate sun exposure. A room with high ceilings, extensive afternoon sun, poor insulation or frequent door opening may need more capacity or may cool more slowly.
Tom’s Guide reported that the related 8,000 BTU AW0822TW1W quickly cooled an 8-by-10-foot room. That is a small-room result and should not be extrapolated to every 350-square-foot space.

Will it fit your window?
The listed fit range is 25 to 38.6 inches wide with at least 15.2 inches of window height. The unit itself is 20.3 inches wide, 20.5 inches deep and 14.6 inches high. Its 51.8-pound weight makes installation a two-person job for most households, especially on an upper floor.
Recommended Free Tools
- Measure the clear opening between the window jambs, not the outside trim.
- Confirm that the sill can support the supplied bracket and that the sash can close against the unit.
- Check that the window opens at least 15.2 inches vertically and falls within the 25–38.6-inch width range.
- Plan a two-person lift, secure the adjustable sliding-arm bracket, then extend the side curtains to close gaps.
- Use a properly grounded 115-volt outlet. Avoid an extension cord unless the installation instructions explicitly permit it.
Hisense says the bracket’s sliding arms simplify positioning and the curtains reduce air leaks and outside light. In practice, careful sealing still matters: gaps can increase drafts, noise and cooling time.

How do Wi-Fi, Matter, Alexa and Google work?
The ConnectLife app provides remote monitoring, scheduling and control, according to Hisense. That lets you change settings before arriving home, set a timer or check operation without reaching the unit.
Hisense’s March 2025 announcement also says the UltraSlim line is Matter-certified. Matter certification indicates support for the cross-platform smart-home standard, but the available product information does not establish exactly which Alexa or Google Home features are enabled for this model, or whether every regional firmware version exposes the same controls. Confirm compatibility in the current ConnectLife app and retailer documentation before buying for a specific smart-home setup.
Efficiency and everyday ownership
The HLAW0825TW is rated at 700 watts and is listed as Energy Star certified. The washable filter lowers recurring replacement costs, but it still needs regular cleaning because a clogged filter restricts airflow and can reduce comfort.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Tom’s Guide reported an EER of 15.4 for the older AW0822TW1W. That number belongs to the tested 2022 model and should not be assigned to the HLAW0825TW. Likewise, an official sheet for the non-inverter AW0822DR1W lists 53/57 dB, CEER 10.9 and a two-year warranty; those specifications do not transfer to this product.
Who should buy it?
- Best fit: A bedroom or office up to roughly 350 square feet where a less-obtrusive indoor profile, app control and inverter-style operation matter.
- Good installation candidate: A standard double-hung window within the stated dimensions, with a sturdy sill and nearby 115-volt outlet.
- Look elsewhere if: You need independently verified HLAW0825TW noise figures, a clearly documented Alexa or Google feature set, or a unit for a large, highly sun-exposed or poorly insulated room.
Before purchase, verify the current retailer price, stock, window measurements and local Energy Star listing. Prices and inventory can change, while the 43 dB and 55 dB figures often repeated online refer to the older AW0822TW1W rather than this model.
