The best portable air conditioners for apartments where a standard window vent kit will not fit, covering sliding doors, casement windows, and no-window rooms, ranked by venting flexibility, cooling capacity, and noise.

Honeywell
- ✓14,000 BTU cooling, dehumidifier and fan modes, rated up to 550-700 sq ft
- ✓Dual filtration system: washable pre-filter plus activated carbon

Best for quiet apartments. Honeywell HL14CESWK for buyers who prioritize noise level and filtration over app control.
LG LP0621WSR 6,000 BTU Portable Air Conditioner
LG
- ✓6,000 BTU DOE (8,000 BTU ASHRAE) cooling, rated up to 250 sq ft
- ✓3-in-1 operation: cool, dehumidify, fan
- ✓Easy-roll casters and auto-swing air vent
- ✓Washable air filter with filter alarm
- ✓LCD remote and window installation kit
Pros
- Smallest footprint and lightest weight in this list, easiest to move room to room
- Washable filter cuts down on replacement filter costs over time
- Quieter running than the larger 14,000 BTU units in this list
Cons
- 250 sq ft coverage is meaningfully smaller than the 14,000 BTU models here
- Single-hose design, less efficient in high-heat rooms than dual-hose units
- No smart app or voice control
Best for small rooms. LG LP0621WSR for a studio bedroom or single room where a full-size unit is overkill.
Most portable AC listings assume you have a standard double-hung window and a straightforward vent kit install. Apartment reality is messier, sliding doors, casement windows, or a bedroom with no window at all.
The good news is that every unit still needs to vent heat somewhere, but the kits and workarounds vary more than the spec sheets suggest.
The Whynter ARC-14S 14,000 BTU dual-hose unit tops this list because its outside-air intake recovers cooling faster than single-hose designs, worth the extra setup of a second hose opening.
For renters who want app control from a phone, the BLACK+DECKER BPACT14WT adds Wi-Fi and voice assistant support on top of solid single-hose cooling.
And for a single small bedroom, the LG LP0621WSR's 6,000 BTU output and rolling casters make it the easiest unit to move between rooms as needed.
The Best Portable ACs for Apartments at a Glance
Best overall: Whynter ARC-14S, dual-hose 14,000 BTU with the fastest real-world cooling recovery and a 500 sq ft rating.
Best smart pick: BLACK+DECKER BPACT14WT, single-hose 14,000 BTU with Wi-Fi, Alexa, and Google Assistant support.
Best for quiet apartments: Honeywell HL14CESWK, dual motor design rated at 49 to 52 dB with dual filtration.
Best compact pick: LG LP0621WSR, 6,000 BTU for a single small room, lightest and smallest in this list.
Venting Without a Standard Window
Sliding glass doors need a dedicated vertical slider kit. Most brands sell one separately if it is not included, check before ordering.
Casement windows (crank-open, no horizontal slider) generally cannot use the standard slider panel kit. A few brands sell casement-specific kits, but many renters in this situation instead vent through a nearby wall port or drop ceiling tile if the building allows it.
No window in the room at all rules out a standard portable AC. The only workable options are a through-wall vent (if permitted by the lease) or moving the unit to an adjacent room with a window and running ducting, which is inefficient and not something we recommend as a primary solution.
What Matters Most for Apartment Installs
Hose length: most kits include 5 to 7 feet of hose. If your unit needs to sit more than a few feet from the window, check the included hose length before buying, since extension hoses can reduce airflow.
Noise, if you share thin walls: the Honeywell HL series' dual motor design at 49 to 52 dB is noticeably quieter than single-motor units at the same BTU rating.
Weight and casters: apartment moves are more frequent than homeowner moves. The LG LP0621WSR's smaller footprint and rolling casters make seasonal storage and room-to-room moves easier.
