The air conditioner works well in my 480 sq ft garage, but it takes a while to cool down in the Florida heat. Once it's cooled, it makes working in the garage comfortable. I recommend turning it on the night before so it's cool in the morning, and try to minimize opening the garage door too often.

The weather is actually hot in the southern region, so it's not shocking that things are a bit slower.

It was difficult to install.

We had to replace our old unit during a heatwave and this one seemed like a good choice. We didn't want anything too fancy and it cools well. It also looks nice. Just like others have mentioned, we had to raise it a bit for the drain to work properly. I'm still trying to understand how the timer works, the manual doesn't have enough information for me. The only thing I would change is to add illumination to the buttons, they're hard to see in low light.

The 14,000 btu Impecca Portable AC works best when allowed to sit upright for 24 hours before use. It is recommended to keep the blue tape strips on the unit to seal the seams. The unit is most effective when used in a window installation, as the air dryer vent exhaust did not work well. Despite this, it easily cools a closed bedroom and is still able to cycle on and off with the door open.

When the compressor starts, the noise level does not increase, and the fan noise is dominant, resulting in a low total noise level. The remote control has a minimum temperature setting of 64 degrees, and there is some residual heat into the room from the warm exhaust tube. It is noted that a window AC unit may be more efficient in terms of preventing heat from entering the room.

The unit was installed using a clothes dryer exhaust vent tube with the included hose, and it is best installed with the vent on the back in a straight line of sight to the bottom of the window or dryer vent. The unit only requires the window to be open 7 inches and can accommodate window widths ranging from 20 to 59 inches without heavy supports for the window vent.

In terms of electric usage, I noted that the unit uses 12 amps, equivalent to 1,500 watts, resulting in an electric cost of about 25 cents per hour or $6 per day with an example electric cost of 17 cents per KWh. Central AC is considered to be more efficient in terms of electric cost.

Overall, my observation is that central AC is the most efficient in terms of electric cost, while window and portable AC units can be effective when used in a single closed room. It is also mentioned that the remote control batteries are not included, requiring 2 AAA batteries.

This product is extremely efficient and can easily cool down my room even on the coldest setting during hot summer days. The only issue is that the tube does not secure well in the window slider, causing it to fall out and release hot air back into the room. I had to duct tape it in place, which looks unappealing. A longer and more adjustable tube, along with a better locking mechanism, would solve this problem.

The portable ac is effective, but it is very loud. It is noticeably louder than a window AC unit.

I am very satisfied with this air conditioner overall. It cools my room very quickly, but it does use a lot of energy. I noticed a significant increase in my power bill after using it. The exhaust tube gets very hot, which I didn't expect, but adding an insulated cover helped to cool it down a bit. The unit cools my 20 x 18 room quickly and effectively, and it was easy to install in my window. It is noisy, but as a night shift worker, I find the sound helps to block out street noise and is actually comforting. Overall, I am happy with this air conditioner.
