LG is one of the biggest names in home appliances, and its air conditioners stand out for smart features: most of its portable models connect to the LG ThinQ app and respond to Alexa or Google voice commands. If you searched for an LG portable AC with 12,000 BTU, you may have noticed a confusing detail on the box. LG, like other brands, lists two numbers: a higher ASHRAE figure and a lower DOE or SACC figure. The same machine might be called 12,000 BTU and 8,000 BTU at once.
Here is the simple explanation. BTU (British thermal unit) measures how much heat an air conditioner can remove from a room. ASHRAE is an older test done in steady lab conditions. DOE, also called SACC (seasonally adjusted cooling capacity), is the newer U.S. Department of Energy test that accounts for real-world losses, such as warm air leaking in through the exhaust hose. That is why the DOE number is always lower, and it is the better guide for sizing. The six LG units below range from a 6,000 BTU window model to 10,000 BTU SACC portables, with two true 12,000 BTU ASHRAE portables in the middle.

LG 8000 BTU
Best for: Bedrooms and home offices up to 350 sq ft
Pros
- 12,000 BTU ASHRAE, 8,000 BTU DOE
- LG ThinQ app plus Alexa and Google
- Washable filter
- Auto-swing vent
Cons
- No inverter
- 51 dB listed
The LG 8000 BTU portable air conditioner, model LP0823GSSM, is rated 8,000 BTU DOE and 12,000 BTU ASHRAE, and LG says it cools rooms up to 350 square feet. That makes it a typical choice for a bedroom, home office, basement room or attic space. It is a 3-in-1 unit with cool, fan and dry modes; dry mode removes moisture on damp days without heavy cooling.
Smart control comes through the LG ThinQ app, and the listing mentions Google Assistant and Amazon Alexa voice control. A top-mounted LED display, 24-hour timer and auto-swing air vent handle daily use. The washable filter slides out, and LG suggests rinsing it twice a month. It uses R32 refrigerant, runs on standard 115-volt power and lists 51 dB of noise. There is no inverter compressor, which means the compressor switches on and off rather than slowing down.
This model suits most first-time buyers looking for a 12,000 BTU ASHRAE portable for one average room. If quiet running is your top priority, the LP0825WSSM or the Dual Inverter LP1022FVSM are better matches.
LG 7,300 BTU LP0725WSSM for Smaller Rooms

LG 7,300 BTU
Best for: Smaller rooms up to 300 sq ft
Pros
- WiFi and voice control
- Remote included
- 50 dB listed
Cons
- Lowest cooling in portable group
- Only two fan speeds
The LG 7,300 BTU portable, model LP0725WSSM, is rated 7,300 BTU DOE and 11,000 BTU ASHRAE and covers rooms up to 300 square feet, about 15 by 20 feet. It offers the same cool, fan and dry modes, two cooling and fan speeds, a built-in dehumidifier, an auto-swing vent and a 24-hour timer.
Controls include the LG ThinQ app, Alexa and Hey Google voice commands, simple electronic controls on the unit and an included remote. The listing gives 50 dB of noise and R-32 refrigerant, with no inverter.
This unit suits a small bedroom, nursery or dorm-style room where a 12,000 BTU ASHRAE model would be more than you need. For rooms closer to 350 square feet, step up to one of the 12,000 BTU ASHRAE models. For more small-room options, our 8,000 BTU portable air conditioner guide is a helpful comparison.

Best for: Light sleepers with larger rooms
Pros
- Dual Inverter compressor
- As low as 44 dB in sleep mode
- Cools up to 450 sq ft
- Up to 40% power savings claimed
Cons
- Larger than a 12,000 BTU need
The LG 10000 BTU SACC(14000 ASHRAE) Portable air conditioner, model LP1022FVSM, is the only model here with LG’s Dual Inverter compressor. An inverter compressor adjusts its speed to hold the temperature steady instead of cycling on and off, and LG claims up to 40% power savings compared with non-inverter models. It is also the quietest unit listed, at sound levels as low as 44 dB in sleep mode.
It cools up to 450 square feet, offers cool, fan and dry modes, connects to the LG ThinQ app and works with compatible smart speakers. The listing adds a washable filter, a filter reminder light and R-32 refrigerant.
Choose this model for a larger living room or for light sleepers who want a quieter unit. It is rated above 12,000 BTU ASHRAE, so for a standard bedroom the smaller 12,000 BTU models are usually enough.

LG 6000 BTU Window Air Conditioner[2024
Best for: Small rooms with a double-hung window
Pros
- Fits 21 to 35 inch windows
- EZ Mount kit included
- WiFi, Alexa and Google
Cons
- Window unit, not portable
- Only 250 sq ft
The LG 6000 BTU Window Air Conditioner, model LW6024RSMX, is not a portable unit. It is a window air conditioner, included here because some shoppers weigh a window unit against a portable one. It cools small rooms up to 250 square feet and installs in a double-hung window between 21 and 35 inches wide and at least 12 inches high, using the included EZ Mount kit.
Features include WiFi control through LG ThinQ, Alexa and Google Assistant compatibility, two cooling and fan speeds, an LCD display, a remote control, a 24-hour timer, a washable slide-out filter with check filter alert and R32 refrigerant. The listing gives 52 dB of noise. LG suggests cleaning the filter every 30 days.
A window unit sits outside the room’s floor space and has no exhaust hose, which is why many people find it more efficient for its size. If your window is a casement or slider, or your lease does not allow window units, stick with one of the portables.
LG 8,350 BTU LP0825WSSM for Quieter 12,000 BTU Cooling
Best for: Quiet bedrooms up to 350 sq ft
Pros
- 12,000 BTU ASHRAE, 8,350 BTU DOE
- 48 dB listed
- ThinQ, Alexa and Hey Google
- 24-hour timer
Cons

The LG 8,350 BTU portable, model LP0825WSSM, is the second 12,000 BTU ASHRAE model in this group, rated 8,350 BTU DOE and covering rooms up to 350 square feet, about 14 by 25 feet. Its DOE figure is slightly higher than the LP0823GSSM, and it lists 48 dB of noise compared with 51 dB.
It has the same smart features as its sibling LP0725WSSM: LG ThinQ, Alexa and Hey Google control, electronic controls on the unit, an included remote, two cooling and fan speeds, a 24-hour timer, a built-in dehumidifier and an auto-swing vent. It runs on 115 volts with R-32 refrigerant and no inverter.
This is a strong pick for bedrooms where both cooling and a bit less noise matter. For more 12,000 BTU ASHRAE choices across brands, see our 12,000 BTU air conditioner guide.
LG 10,200 BTU Cool and Heat Portable for Year-Round Use
Best for: Rooms needing cooling and winter heat
Pros
- Cools and heats
- Up to 450 sq ft
- Wheels for moving rooms
- Washable filter
Cons
- No inverter
- Specs call it a window install
The LG 10,200 BTU portable air conditioner adds heating. It is rated 10,200 BTU for cooling (14,000 ASHRAE) and 12,000 BTU for heating, covering rooms up to 450 square feet. Modes include cooling with dehumidifying, heating in cold weather and fan. Wheels make it easy to roll between rooms.
It shares the ThinQ app, Alexa and Google control, top-mounted LED display, 24-hour timer, washable filter and R32 refrigerant of the other models, and lists 51 dB of noise. One detail to note: the specs list the installation type as window even though the title and description call it a portable air conditioner with an installation kit and hose.
This unit suits sunrooms, basements or garages that are hot in summer and chilly in winter. If you never need heat, the Dual Inverter LP1022FVSM is quieter at a similar size.
How to Choose the Right LG Portable AC
Use the DOE or SACC number for sizing. A 12,000 BTU ASHRAE LG portable is 8,000 to 8,350 BTU DOE and suits about 350 square feet. Bigger rooms up to 450 square feet call for the 10,000 or 10,200 BTU SACC models.
Think about noise. The Dual Inverter LP1022FVSM lists 44 dB in sleep mode, the LP0825WSSM lists 48 dB, and the others sit between 50 and 52 dB.
Decide if you need heat. Only the 10,200 BTU model heats.
Portable or window. Portables roll between rooms and vent through a hose; the LW6024RSMX mounts in a window. Our basic portable air conditioner guide covers simpler portables if you do not need smart features.
