The Honeywell 11,000 BTU Slim Portable AC is built for rooms where floor space is tight. Honeywell rates it at 11,000 BTU on the ASHRAE scale and 8,000 BTU on the SACC scale, and says it covers rooms up to 500 square feet. The body is only 13.18 inches wide and 11.22 inches deep, which is narrow for this capacity. It is a newer entry among the single-hose portable air conditioners we cover, with a 4.1 out of 5 average across a small number of ratings so far.
The model number is HX2CESAWG8. It runs on 115 volts, draws 1200 watts, and works as an air conditioner, a fan or a dehumidifier.
Our Verdict
The Honeywell HX2CESAWG8 is the pick when you need real cooling but have little room for the unit. It fits between furniture or in a narrow corner, and 8,000 BTU SACC is enough for a bedroom, office or small living room. Honeywell includes a full window kit plus bonus foam insulation, which helps with a cleaner seal.
The drawbacks are noise and a lack of smart features. The listed 56 dB is louder than many rivals, and control is by touch panel and remote only. If footprint matters most, it is a strong option. If you need quiet nights, look at a lower-noise model.

Cooling Capacity and Room Size
Honeywell gives 11,000 BTU on the older ASHRAE scale and 8,000 BTU on the SACC scale. The SACC figure accounts for the heat a single-hose portable pulls back into the room, so it is the better one to compare with other portables.
Honeywell rates the unit for rooms up to 500 square feet. In practice, 8,000 BTU SACC is a comfortable fit for a bedroom, home office or small living room, and it will be working hard in a large or sunny space near that upper limit. The compressor is a non-inverter type that cycles on and off. You can set the temperature from 61 to 88 degrees F.
Installation and Fit
The slim body is the reason to buy it. At 13.18 inches wide, 11.22 inches deep and 27.48 inches tall, it fits into spots where a typical portable will not. At 50.7 pounds, it is also lighter than many units of similar capacity, and grab handles and caster wheels make it easy to move.
The box includes a complete window installation kit plus a bonus foam insulation kit for a tighter seal. Keep the exhaust hose short and straight, and use the foam to block gaps around the window panel so less warm air leaks in.
Noise, Energy Use and Efficiency
The listed noise level is 56 dB. That is on the louder side for a single-hose portable, so it is better suited to an office or living room than a bedroom for a light sleeper. Three fan speeds let you trade cooling speed for lower noise.
The unit draws 1200 watts and carries a certified CEER of 7.2. That is a fair figure for a non-inverter portable of this size. The 24-hour timer and customizable schedules on the digital thermostat let you limit run time and save energy.
Controls and Features
A top-mounted LED display and touch controls sit on the unit, and a full-function remote lets you adjust settings from across the room. The digital thermostat starts the unit based on pre-set conditions, and the 24-hour timer covers on and off times.
There is no app or voice control. For many buyers, the remote, timer and three fan speeds are all they need for daily use.
Dehumidifying and Filter Care
Dehumidifier mode is strong for a portable, with a listed capacity of up to 76 pints per day. That helps in damp basements, humid climates and muggy summer evenings. Fan mode moves air when you do not need cooling. Follow the manual for draining in very humid weather.
The mesh filters are removable and rinse easily under the tap. Clean them regularly to keep airflow strong.
Who It Suits Best
This Honeywell suits apartments, offices and compact rooms where every inch of floor counts. It is a good fit beside a desk, between a bed and a dresser, or in a narrow window bay. Buyers who want a known brand with U.S. customer support will like the backing behind it. It also suits humid homes, where the strong dehumidifying capacity helps a room feel more comfortable even at a moderate temperature setting. Light sleepers and smart home users are better served by other models.
