Many apartments and older homes have a wall sleeve but only a standard household outlet beside it. That rules out a lot of larger wall units, which need a 230 volt receptacle. Our list of the best 115V through-the-wall air conditioners focuses on cooling-only wall units that plug straight into a normal outlet, from compact bedroom models to units big enough for a living room. To browse every model we cover, visit our Cooling-Only Through-the-Wall Air Conditioners page.
We compared these 115V through-the-wall air conditioners on cooling capacity, room size, power draw, noise, sleeve fit and controls. Every unit here runs on 115 volts, so no electrician is needed as long as your outlet and circuit are in good shape.

Top 3 115V Through-the-Wall Air Conditioners Reviewed
#1 LG 9,800 BTU Through-the-Wall Air Conditioner: Best Overall
Why We Picked It
The LG LT1016CER is the benchmark 115V wall unit. It has a 3.9 rating from 590 ratings, the most in this guide, and it pairs 9,800 BTU of cooling for rooms up to 440 square feet with one of the lowest power draws for its size at 920 watts. On a typical household circuit, that leaves room for lights and electronics without tripping a breaker.
LG lists an EER of 10.7 with R-32 refrigerant, and energy saver mode shuts the compressor off between cycles while the fan keeps air moving. Three cooling and fan speeds, dry mode, 4-way air deflection, a 24 hour timer, auto restart and a remote cover daily use. The 24 inch chassis is designed to fit most universal sleeves, and LG includes a trim kit, a rear mesh grille and insulation foam.
Key Specifications
- Cooling Capacity: 9,800 BTU
- Room Size: Up to 440 sq ft
- Power: 115 volts, 920 watts
- Efficiency: EER 10.7
- Noise Level: 56 dB
- Weight: 77 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
The Amazon title calls it a 10,000 BTU unit, but LG’s specifications list 9,800 BTU. Use the lower figure when sizing.
Best For
This unit is best for bedrooms, offices and studios up to 440 square feet where the sleeve has a standard outlet.

#2 Whirlpool 10,000 BTU Wall Air Conditioner: Quietest Full-Size 115V Pick
Why We Picked It
The Whirlpool WHAT101-1BW is the quieter alternative to the LG, with a listed 54 dB against LG’s 56 dB, and it adds a few practical extras. It cools spaces up to 450 square feet, draws 980 watts, and plugs in through an attached 5.9 foot LCDI 3-prong cord that fits any standard 115 volt outlet. It has a 4.0 rating from 35 ratings.
The 8-way directional louvers give finer control over airflow than the usual 4-way design, which helps when the bed or sofa is off to one side. Eco and Sleep functions trim running costs, a programmable 24 hour timer handles scheduling, and the quick-access filter slides out from the front without removing the panel. Whirlpool says it fits sleeves from 24.5 to 27 inches wide, includes both a trim kit and a rear grille, and backs it with a 2 year limited warranty.
Key Specifications
- Cooling Capacity: 10,000 BTU
- Room Size: Up to 450 sq ft
- Power: 115 volts, 980 watts
- Noise Level: 54 dB
- Sleeve Fit: 24.5 to 27 inches wide
- Weight: 64.2 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
Whirlpool sells a separate version of this unit that needs a high-voltage outlet. Make sure you order the WHAT101-1BW for a standard outlet.
Best For
This unit is best for bedrooms and home offices where a lower sound level and a longer warranty matter.

#3 LG 11,800 BTU Through the Wall Air Conditioner: Most Cooling on 115V
Why We Picked It
The LG LT12124CNR is the strongest unit in this guide that still runs on a standard outlet. LG rates it at 11,800 BTU for rooms up to 530 square feet, which covers medium living rooms, large primary bedrooms and studios that a 10,000 BTU class unit struggles with on hot afternoons. It draws 1110 watts, so give it a circuit without other heavy appliances.
It shares LG’s universal 24 inch chassis, so it can replace a smaller LG wall unit in the same sleeve. LG lists an EER of 10.6 with R-32 refrigerant, and the feature set matches the LT1016CER: three cooling and fan speeds, energy saver mode, dry mode, 4-way air deflection, a 24 hour timer, a check filter alert and a remote. For a new opening, LG lists a wall cutout of 25.88 by 15.53 inches for the sleeve.
Key Specifications
- Cooling Capacity: 11,800 BTU
- Room Size: Up to 530 sq ft
- Power: 115 volts, 1110 watts
- Efficiency: EER 10.6
- Noise Level: 60 dB
- Weight: 76 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
The extra capacity comes with more noise. For a small bedroom, the 9,800 BTU LG or the Whirlpool is the better fit.
Best For
This unit is best for living rooms and large bedrooms up to 530 square feet with only a standard outlet at the sleeve.

Other Models Worth Considering
Keystone 10,000 BTU Wall Air Conditioner and Dehumidifier (KSTAT10-1E). A 10,000 BTU unit for spaces up to 450 square feet with a listed 50.2 dB, the lowest of the full-size units here. Its remote reads the room temperature and sends it to the unit every 3 minutes, and it removes up to 2.3 pints of moisture per hour. It draws 1040 watts.
TCL 12,000 BTU Smart Through-the-Wall Air Conditioner (H12T9E1-A). A 12,000 BTU smart unit for spaces up to 550 square feet that runs on a standard outlet at 1160 watts. It works with the TCL Home app, Alexa and Google Assistant, and TCL lists 56 dB. It needs a 26 by 20 by 15.75 inch sleeve, which is not included.
OLMO 8,000 BTU Through-the-Wall Air Conditioner (OW-A08AC115WF). A compact 8,300 BTU/h unit that ships with its own wall sleeve and a built-in smart kit for app and voice control. OLMO lists 49.5 dB, and it weighs 80 pounds.
What to Expect from 115V Through-the-Wall Air Conditioners
A 115V wall unit plugs into the same kind of outlet as a lamp, so installation is mostly mechanical: slide it into the sleeve, fit the trim and plug it in. The trade-off is capacity. Most 115V wall units top out around 12,000 BTU, so they suit bedrooms, offices, studios and medium living rooms rather than large open-plan spaces.
For larger rooms, see our guides to 230V through-the-wall air conditioners and 12,000 BTU through-the-wall air conditioners. The product cards show the current price for each unit.
How to Choose a 115V Through-the-Wall Air Conditioner
Size the Unit to the Room
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Check the Circuit, Not Just the Outlet
A standard outlet is only half the story. A 12,000 BTU unit at well over 1,000 watts can trip a breaker if it shares a circuit with a microwave, space heater or hair dryer. If you can, put the unit on a circuit of its own, and never run it through a light-duty extension cord.
Match the Sleeve
The LG, Whirlpool, Keystone and OLMO units use a chassis about 24 inches wide, and Whirlpool states a fit range of 24.5 to 27 inches. TCL specifies a 26 inch class sleeve. Measure your existing sleeve before ordering, or choose the OLMO if you need a sleeve as well.
Noise and Smart Features
For bedrooms, the Keystone, OLMO and Whirlpool list the lowest sound levels here. For app and voice control, choose the TCL or OLMO.
