The GrowthWing 14,000 BTU Portable AC is a 3-in-1 portable air conditioner with Wi-Fi, voice and remote control, a self-evaporating system and a quiet Sleep Mode. It rolls to wherever you need it and vents through a window kit that fits a wide range of sliding windows. Among the portable air conditioners we track, it stands out for its smart features, and it is sold as model HAC904WF.
GrowthWing rates it for rooms up to 700 square feet. It has 4.7 stars from 78 ratings, and we evaluated it based on the manufacturer’s specifications.
Our Verdict
The GrowthWing is a strong pick for renters and anyone who cannot fit a window unit, especially if you want to run the air conditioner from your phone. The auto-evaporation system reduces manual draining, the Sleep Mode is listed at 42 dB, and the window kit installs without tools.
The trade-off is the capacity figure. GrowthWing quotes 14,000 BTU on the ASHRAE scale and does not list the lower DOE (SACC) rating that portable units are usually compared on, so real-world output will be lower than the headline number. It is also 66 pounds, so moving it between floors takes effort.

Cooling Capacity and Room Size
GrowthWing lists 14,000 BTU of ASHRAE cooling from an upgraded compressor and a wide 77° air outlet, and rates the unit for rooms up to 700 square feet. The wide outlet spreads air across more of the room than a narrow vent.
Treat the 700 square foot figure as a best case. ASHRAE ratings are measured under easier conditions than the DOE’s SACC method, and portable units lose some cooling to the heat from their exhaust hose. The listing does not give a SACC figure, so for a room that gets strong afternoon sun, plan on a space well under the maximum.
It works best in a living room, a large bedroom or a home office where you want strong cooling without a permanent installation.
If your lease or building rules allow a window unit, a window air conditioner of similar capacity will usually cool more efficiently, because its hot side sits fully outdoors. A portable unit makes sense when a window unit is not allowed, when the window is an unusual size, or when you want to move cooling from room to room through the day.
Installation and Fit
Setup takes a few minutes with the included window kit and exhaust hose. The adjustable panels fit most horizontal and vertical sliding windows from 20.39 to 67 inches, and GrowthWing describes the install as tool-free.
Place the unit close to the window so the exhaust hose stays short and straight, which helps cooling performance. It plugs into a standard 115 volt outlet. At 66 pounds and 25.5 inches tall, it rolls easily on a flat floor but is heavy to carry upstairs.
Noise, Energy Use and Efficiency
GrowthWing lists operation as low as 42 dB in Sleep Mode, and the display dims automatically at night. That is quiet for a portable unit, though expect more sound at higher fan speeds during the day.
Power draw is listed at 1200 watts, and the specifications give annual energy use of 946 kWh per year. The listing does not mention a CEER rating or ENERGY STAR certification. The unit uses eco-friendly R32 refrigerant.
Controls and Smart Features
You can control the GrowthWing through its app, by voice, or with the included remote. In the app you can adjust temperature, fan speed, mode, timer and schedules, so the room can be cool before you get home.
Pairing follows a simple sequence: download the compatible app, plug in and turn on the unit, press and hold the Mode button until the indicator flashes, then tap Add Device and select your home Wi-Fi. The listing does not name the voice assistants it supports, so check compatibility with your smart speaker before you buy.
The 3-in-1 design covers cooling, dehumidifying and fan modes, so the unit can dry out a damp room or simply move air on mild days.
Maintenance and Drainage
The self-evaporating system recycles most of the condensate it collects, giving up to 72 hours of drainage-free cooling in most environments. That removes the most annoying chore with many portable units.
For extended dehumidifier use, connect the included drain hose and run it to a floor drain or bucket. In very humid weather, check the unit more often even in cooling mode. Clean the filter regularly to keep airflow strong.
Pros and Cons
| Pros | Cons |
|---|---|
| App, voice and remote control | No SACC (DOE) rating listed |
| 72-hour auto-evaporation | 700 sq ft claim is optimistic for a portable |
| As low as 42 dB in Sleep Mode | Heavy at 66 pounds |
| Tool-free kit for 20.39″ to 67″ windows | Voice assistants not named in the listing |
| 4.7 stars from 78 ratings | Only a 1-year limited warranty |
Who Should Buy It
| Who Should Buy It? | Who Should Look Elsewhere? |
|---|---|
| Renters who cannot install a window unit | Buyers who need a verified SACC rating |
| Smart home users who want app control | Very large open spaces |
| Bedrooms where a quiet Sleep Mode matters | Anyone who needs to carry it up stairs often |
| Rooms with sliding windows | Casement windows without an adapter |
Final Verdict
The GrowthWing 14,000 BTU Portable AC brings app and voice control, 72-hour auto-evaporation and a 42 dB Sleep Mode together in a portable unit that installs without tools. It suits renters and anyone with sliding windows who wants smart control and little maintenance. The compromise is an ASHRAE-only capacity figure that overstates real output, plus a heavy body.
