6 Best 12,000 BTU Portable Air Conditioners of 2026
We compared six 12,000 BTU single-hose portable air conditioners on real-world cooling, room coverage, noise, smart features and drainage.
By Daniel Brooks
Updated October 17, 2026
12,000 BTU portable air conditioners sit in the sweet spot of the single-hose range. They have enough capacity for a large bedroom, home office or average living room, and they are usually lighter and cheaper than the largest models. Our list of the best 12,000 BTU portable air conditioners compares six of them on real-world cooling, room coverage, noise, smart features and drainage. For other sizes and every single-hose model we cover, see our Single-Hose Portable Air Conditioners page.
The 12,000 BTU figure is an ASHRAE rating. Brands that also list a SACC or DOE figure put it around 8,000 BTU for this size, which is a better guide to real-world cooling. All six run on a standard household outlet and come with a window kit.

Top 3 12,000 BTU Portable Air Conditioners Reviewed
#1 BLACK+DECKER 12,000 BTU Portable Air Conditioner: Best Overall
Why We Picked It
The BLACK+DECKER BPT08WTB is the most dependable 12,000 BTU unit in this guide, with a 4.2 rating from 216 ratings from a brand that has sold portables for years. It delivers 12,000 BTU of cooling for rooms up to 550 sq ft, and BLACK+DECKER pitches it for apartments, cabins and larger living spaces.
It combines an air conditioner, dehumidifier and fan in one machine. The highlight is the full-function remote with a FOLLOW ME function, which turns the remote into a thermostat so the unit cools to the temperature where you are rather than at its own vent. An auto water evaporation feature helps limit emptying the bucket, so upkeep stays low through the summer. You wheel it near a double hung or sliding window and install it with the included exhaust hose and window adapter, and the listing gives a window opening width of 20.5 to 48 inches. The filter is washable, and it weighs 55.4 pounds.
Key Specifications
- Cooling Capacity: 12,000 BTU
- Room Size: Up to 550 sq ft
- Noise Level: 53 dB
- Remote: FOLLOW ME thermostat
- Drainage: Auto water evaporation
- Weight: 55.4 pounds
| Pros | Cons |

Things to Consider
BLACK+DECKER does not list a SACC rating for this model, so you cannot compare its real-world output directly with the LG or Frigidaire. It is a remote-only unit with no app.
Best For

Check the current price and availability of the BLACK+DECKER 12,000 BTU Portable Air Conditioner on Amazon.
#2 LG 8,350 BTU (DOE) Portable Air Conditioner: Best for Smart Control
Why We Picked It
The LG LP0825WSSM is the best-connected unit in this size class. It has a 4.2 rating from 29 ratings.

Traditional electronic controls and a remote are included too.
LG rates it at 12,000 BTU ASHRAE and 8,350 BTU DOE, one of the higher DOE figures here, and says it is ideal for medium rooms of 350 sq ft, about 14 by 25 feet. It lists 48 dB and a SEER of 7.4, both good figures for a non-inverter portable. It is a 3-in-1 unit with Cool, Fan and Dry modes and 2 cooling and fan speeds, and an auto-swing air vent and a 24-hour timer round out the features. It uses R-32 refrigerant and runs on 115 volts.

You manage it through the app or the included remote, adjusting mode, temperature, wind speed and timer, or use the top LED panel directly. It is a 3-in-1 unit with cooling, fan and dehumidifier functions, and a built-in smart sensor adjusts compressor use for better efficiency. The self-evaporating system reduces draining, and dual drain options let you run a top drain for continuous use or empty it from the bottom. The window kit fits vertical or horizontal windows from 25.6 to 50.2 inches, and 360 degree wheels and side handles make it easy to move. It is also slim at 11.8 inches wide, and the listed SEER is 6.7.
