The dehumidifier works over the clock and the temperature is constant while keeping it dry inside and collecting about 1.9 pints per hour.

This particularly makes it a chore to take constant care of throwing the gathered water if you live in a more humid climate but, in general, it is not a big issue. We all know that the body cools off once we go to sleep so the unit’s sleep mode is ideal for this, as it increases the temperature by 2 degrees half an hour after the mode is activated and then by 2 more after another thirty minutes.

It is not as heavy as the sleek looking Frigidaire, making it easier to move around when installing and the installation is just as easy with the kit, which comes in the package – simply follow the manual and you should not experience any issues.

8000 BTU air conditioners like this one can cool less space versus the larger 10000 BTU ones, however, the price gap is significant for not much more square footage you get from the bigger ones. This unit is more than capable of cooling a 350 square foot space like a master bedroom, a living room, a studio or office space.

As far as dehumidification goes, the air conditioner can gather up to 1.76 pints per hour. You can easily set any fan speeds, work modes and temperatures to your liking from across the room using the LCD display remote control.

And when you cannot seem to find the remote like it usually goes with those, the LCD onboard control display on the unit allows you to set up every option just as easy. Modes include the Sleep mode, which once activated, will gradually increase the temperature in accordance with the usual room temperature, while your body cools off when asleep.

There is also a programmable 24-hour timer, which gives you the opportunity to set the AC to cool the space on your daily schedule. The electrical bill would be even better looking when you use the Eco mode, which uses less energy to maintain the same chill and cool atmosphere without overusing power.

5. BLACK+DECKER BPACT08WT Portable Air Conditioner

BTUs 8000
Room Size150 Sq. Feet
Weight52.9 pounds
Dimensions16.5×11.5×26 inches

Finally, let us take a look at one of the portable options of the 8000 BTU range. The Black&Decker BPACT08WT portable air conditioner is a convenient unit to have around the house if you need more than one place to be cooled off.

The main difference between portable air conditioners like this one and mounted compact air conditioners is that for the same cooling power, the portable ones can cool a smaller space. At the same time, it is a great option to be able to put it in any room you desire, as you do not have to buy a separate unit for each space.

That being said, this portable air conditioner can keep an area of up to 150 square feet cool as ice, may it be a dorm room, bedroom, garage, small apartment space, office or a tool shed in the summer when the heat is inevitable. If you opt for portability, you cannot go wrong with this model.

Operating the unit is simple and easy with the LED digital display on the board as well as through the remote control, which allows you to operate the air conditioner from a distance and choose the settings and temperature you prefer. One of the great features is the four wheels on the bottom that make it effortless to move from room to room as you please.

Energy Star certified this air conditioner would not only keep you cool at all times but also help you save up on utility bills. Cleaning the filter is simple as it is situated on the back of the unit and easily accessible. The air conditioner will let you know when you need to clean it so this chore would not even be a bother.

One downside to this great module is that it can be quite noisy at times when setting on higher settings and needs to keep a cooler temperature over long periods of time. At 75 decibels on high settings, it can surely be a nuisance to some. Aside from this, since this is a portable smaller unit, it can only be used optimally for smaller rooms as it will struggle with some bigger spaces.

Overall, it certainly is one of the best, if not the best, options on the market for an 8000 BTU portable air conditioner, so make sure you take this into consideration next time you go to the store or check online in search of a new cooling unit.

Essentially find the center of your window using a measuring tape in order to position the unit properly.

Next, you would want to attach the side panels and screw them on so that the air conditioner is completely settled in the window space and closed by the side panels on both sides. Lastly, make sure to secure the AC in place with the L brackets provided in the installation kit or take some from your handy toolbox.

As for the portable air conditioners, installation is quite simple.
