The Whirlpool WHAW182CW 18,000 BTU Window Air Conditioner is a 230V unit for large rooms up to 1,000 square feet. It pairs strong cooling with 4.75 pints per hour of dehumidification, an electronic control panel, a remote and 8-way directional louvers. Among large conventional window air conditioners, it suits big living rooms, open-plan areas and basements.
It requires a 230V circuit, a large window and serious lifting help. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This Whirlpool is a capable large-room unit. Its strongest points are 18,000 BTU of cooling, 4.75 pints per hour dehumidification, 3 cooling speeds, eco and sleep modes, a programmable 24-hour timer, 8-way directional louvers, a remote and a Clean Alert for the filter.
The trade-offs are significant. It weighs 116.8 pounds, needs a 230V outlet and a window at least 28 inches wide and 19 inches high, and the listed noise level is 60 dB. There is no inverter. If you have a 230V circuit and a large space to cool, it is worth considering.

Cooling Capacity and Room Size
Whirlpool rates the WHAW182CW at 18,000 BTU for rooms up to 1,000 square feet and names apartments, bedrooms and living rooms. In practice, it is best matched to a large open living area, a finished basement or a big family room.
The 4.75 pints per hour dehumidification rate is high and valuable in humid climates. Just make sure the room needs this capacity; in a space well under 700 square feet, the unit will cool quickly and cycle off before removing much moisture.
For open-plan spaces that include a kitchen, the ENERGY STAR guidance adds 4,000 BTU to the requirement. That means a 1,000 square foot area with cooking may need more than this unit provides, while a large living room or basement without a kitchen is a better match.
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 |
Adjust for your room: 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.
At its listed 18,000 BTU, it lines up with rooms of about 700 to 1,000 square feet, which matches Whirlpool’s coverage claim.
Installation and Fit
Whirlpool lists a compatible window width of 28 to 41 inches and a minimum window height of 19 inches. A window mounting kit is included.
The cabinet measures 23.6 inches deep, 24.4 inches wide and 17.9 inches tall, and weighs 116.8 pounds. That is a job for at least two strong people, and a professional installer is worth considering. Follow the manual for support brackets. The outlet must be a 230V receptacle that matches the plug; never use an adapter or extension cord.
Noise, Energy Use and Efficiency
The listed noise level is 60 dB, which is typical for an 18,000 BTU fixed-speed unit. It is acceptable in a large living area but not ideal for a bedroom.
The listing gives an efficiency figure of 10.4, labeled as SEER, and a power draw of 1513 watts. Eco mode is designed for energy-efficient operation, and sleep mode is tuned for overnight comfort. The 24-hour timer helps you run the unit only when the space is in use. The compressor has no inverter.
Controls and Smart Features
An electronic control panel with digital display and the included remote handle all settings. You get 3 cooling speeds, eco mode, sleep mode and a programmable 24-hour on/off timer.
The 8-way directional louvers are a real benefit in a large room, letting you send air toward seating areas or across an open space. There is no Wi-Fi or app control.
The three cooling speeds let you trade speed for noise. Use the highest speed to bring a hot room down after a warm day, then switch to a lower speed or eco mode once the space is comfortable. Sleep mode is tuned for overnight use if the unit cools a large bedroom suite.
The timer is especially useful with a unit this powerful. Because it can bring a large room down to temperature fairly quickly, you can schedule it to start shortly before you need the space rather than running it all day.
Maintenance and Drainage
The Clean Alert indicator tells you when the mesh filter should be removed and washed or replaced. In a large unit that moves a lot of air, keeping the filter clean has a noticeable effect on cooling and dehumidifying.
With 4.75 pints per hour of dehumidification, the unit produces a lot of condensate in humid weather. The listing does not describe the drainage method, so check the manual for how water is handled.
Pros and Cons
| Pros | Cons |
|---|---|
| 18,000 BTU for large spaces | Requires a 230V outlet |
| 4.75 pints per hour dehumidification | Very heavy at 116.8 pounds |

| Remote, eco, sleep and 24-hour timer | Needs a window at least 28″ wide and 19″ high |
| Clean Alert filter indicator | No inverter or Wi-Fi |
Who Should Buy It
| Who Should Buy It? | Who Should Look Elsewhere? |
|---|---|
| Large rooms of 700 to 1,000 sq. ft. | Homes with only standard outlets |
| Humid climates that need strong dehumidifying | Bedrooms and small living rooms |
| Homes with a 230V circuit near the window | Anyone without help for a 116.8 pound install |
| Open spaces where airflow direction matters | Smart home users wanting app control |
| Buyers who want a remote and timer | Buyers set on an inverter compressor |
