It’s a great little air conditioning unit. It keeps my room very cool. The instructions were a bit confusing on how to connect the drainage hose. Here are some pictures that will hopefully help. Take the black rubber stopper with the hole in it and insert it into the white cap you unscrew from the top drainage hole. Take the drain hose and connect it to the black rubber part that is sticking out. Finally connect it to the A/C unit top drain outlet securely.

Just what I needed! My unit gets a bit warm during the hotter months and this portable ac unit was just what I needed. It comes with all the pieces and is very easily moved around. I tend to use it in the living room during the day and in the bedroom during those warm nights without any issues of portability. My unit is 1100 sqft and if I position a fan near the unit I can cool the hole place even down the hall. I def recommend this!

The air conditioner itself is fine. It keeps you cool and has nice features. It is a bit loud. The biggest complaint is the way the vent hose connects to the window vent adapter. Keeps falling out and nothing heats up a room like a a/c vent blowing back into the room.

This Cool Bus portable air conditioner is easy to set up and install, just pick a window that you won't worry about opening when you don't need the air conditioning. Very convenient and easy to move. In the description it stated it was also a dehumidifier but this model is not. Living in the North this won't be an inconvenience since there are not too many days in the high heat where we would have to put in the drain hose.Other than that a wonderful little unit that will cool down any room with very little noise and with less power than a window unit.

I recently purchased the Coolblus Portable Window AC unit, and it has exceeded my expectations in both quality and performance. From delivery to setup, the process was seamless. The unit arrived upright, as recommended for immediate installation, and the packaging ensured it was in pristine condition.Installation: The setup process was straightforward, thanks to the included Quick Start Guide and detailed Instruction Manual. After measuring my 35-inch horizontal window opening, I followed the guide's suggestion and trimmed 2 inches off sliding panel B for a perfect fit—this allowed the exhaust opening on panel A to align correctly. I appreciated the thoughtful design of the T-bolt and wing nut lock system, which securely connects the panels. To ensure an airtight fit, I added thin foam insulation strips (not included) to eliminate any gaps—a small enhancement I highly recommend.Connecting the exhaust duct was simple and hassle-free. Attaching the hose to both the unit and the window panels was intuitive, and once the window sash was lowered, my setup felt solid and secure.Performance: This unit comes with three functions: Cool, Dry, and Fan. I primarily use the cooling mode to combat the intense Texas summer heat in my upstairs 200-square-foot room. Setting it to 70°F quickly delivered powerful cooling performance. Both the top control panel and remote are easy to use, and the functionality is straightforward.Noise levels are typical for portable ACs—not disruptive but noticeable, especially at the high fan setting. The front louvers offer flexibility for directing airflow, and the recessed lift handles make the unit easy to reposition if needed.Verdict: The Coolblus AC unit combines thoughtful design, user-friendly installation, and reliable (so far) cooling performance. It's an excellent choice for anyone needing portable climate control in a smaller space. I’m very satisfied with my purchase and look forward to staying cool all summer long. Highly recommended!
