Best Overall:
Frigidaire FFPH1422U1
PROS
CONS
What Recent Buyers Report
Recent buyers are extremely pleased with how easy the unit is to set up when unboxing. Once the unit is unboxed and set up, it immediately produces a powerful cold output to begin cooling your room. It quickly cools a space up to 700 square feet in a short amount of time.
Why it Stands Out to Us
We are most impressed with the output, large coverage area, and the variety of functions that you can choose to enable on this unit. It also has a compact and subtle design that makes it virtually unrecognizable as an air conditioning unit.
We also like the effortless restart feature that will cause the unit to restart from its previous setting if the unit loses power.
Bottom Line
We have chosen the Frigidaire FFPH1422U1 as the best overall windowless air conditioner because it covers a large 700 square foot area and gives users a variety of features to choose from.
Runner-up:
De’Longhi Pinguino Deluxe
PROS
CONS
What Recent Buyers Report
The unit is powerful, quiet, and energy-efficient. These are the features that recent buyers speak of the most. It is also easy to move from one location to the next with the built-in wheels located on the bottom of the unit.
Why it Stands Out to Us
We agree with what recent buyers report. We believe the powerful, quiet, and energy-efficient design of the unit is what makes it stand out from the rest of the competition. We also feel that smart cool technology is another feature that sets this unit apart from the rest. This feature means the unit will only run when necessary according to your position, which ultimately will save on energy consumption as well.
Bottom Line
The De’Longhi Pinguino Deluxe is easily our choice for the best runner-up option because of its stylish design, powerful output, ultra-quiet design, and energy-efficiency.
Best for the Money:
Vremi 10,000 BTU
PROS
CONS
What Recent Buyers Report
It doesn’t get much more affordable than this option, which is what recent buyers are most pleased with. It’s an affordable option to cool a small space up to 350 square feet. This space-saving design helps the unit take up as little room as possible when in use.
Why it Stands Out to Us
We like how effective this unit is for such a relatively low price tag. Although it is not one of the most energy-efficient options on the market, the unit is ideal for spot cooling small rooms up to 350 square feet using one of the four modes on the unit.
We also like that there is a convenient built-in remote control storage tray on top of the unit for you to always store your remote when not in use.
Bottom Line
The Vremi 10,000 BTU windowless air conditioner is a great option for those on a budget who need to cool a relatively small area up to 350 square feet, which is why we have chosen it as the windowless air conditioner unit that is the best for the money.
Best Windowless Portable Air Conditioner:
LG LP1417WSRSM
PROS
CONS
What Recent Buyers Report
Recent buyers report that LG's windowless air conditioner is easy to use, effective, and convenient with Wi-Fi technology capabilities. The unit can also be controlled by Amazon Alexa or Google Assistant, making it even more convenient and easy to use.
Why it Stands Out to Us
We like that the unit has a high output of 14,000 BTU. This allows the unit to cool areas up to 400 square feet. Wi-Fi technology is also another key feature that we feel makes it stand out from much of the competition, especially at this affordable price point.
The unit is easy to set up and use, making it essentially immediately effective as soon as it is unboxed. It also includes a convenient remote control that allows you to control the unit's many different features, including oscillation, sleep mode, and programmable timer.
Bottom Line
The LG LP1417WSRSM is one of the best portable windowless air conditioners because of its compact design and built-in wheels that allow it to easily move from room to room.
Best Small Windowless Air Conditioner:
Black + Decker BPACT14HWT
PROS
CONS
What Recent Buyers Report
The Black + Decker BPACT14HWT is best for buyers who use the unit for small areas, including dorms, apartments, or small bedrooms. Users agree that the unit is not energy efficient, but it doesn't need to constantly run when the unit is used in small areas. This helps reduce the overall amount of energy that the unit consumes.
Why it Stands Out to Us
This unit by Black + Decker stands out to us because it is affordable, ideal for small areas, and has a variety of functions to choose from for such a small and compact design.
The setup and installation of the unit are easy. It requires just a few steps of attaching the drain hose and plugging the unit into an outlet for the unit to operate. This makes it exceptionally easy for most users to set up.
There are 4 different functions you can choose from when using the unit. There is a cool, heat, fan, and dehumidifier setting. This allows you to choose the right function for the exact reason you need.
Bottom Line
The Black + Decker BPACT14HWT is the best option for a small windowless air conditioner because of its compact design, overall effectiveness, and how easy the unit is to use.
What is a Windowless Air Conditioner?
A windowless air conditioner is an air conditioning unit that is not installed in a window. It is ideal to use when you can’t install a window unit air conditioner in the room you need to cool.
We have included windowless air conditioners on our list with wheels and can be moved from one location to the next.
Frigidaire FFPH1422U1
Are All Windowless Air Conditioners The Same?
As you will see in our list below, there are various windowless air conditioners to choose from, and all of them are different from one another. Some windowless air conditioners are stronger than others by providing a stronger and larger output. Other windowless air conditioners are more affordable models and will only cool small areas.
By the end of this article, you will know which windowless air conditioner you should choose and why.
What Size of Windowless AC Do I Need?
To determine what size windowless AC you need, you will have to calculate your room's square footage. To do this, you will measure the length and width of the walls in the room in feet. Then you will multiply the length x the width to determine the area in square footage.
We will use a room with an area of 15’ by 18’ as an example. The total area of the room is 270 square feet. This means you will need a windowless AC with a BTU of around 7,000.
Pros and Cons of Windowless Air Conditioners
Every product has some things that are great and some that may cause you to think twice. Here are the pros and cons of this type of air conditioner:
Pros
Does Not Require a Window
A windowless air conditioner can be placed in virtually any room and is ideal for those conditions in which a window air conditioner is not possible or not allowed.
Easy to Set up
Unlike window units or inverter air conditioners, windowless air conditioners are easy to set up and install. You generally don’t need any HVAC experience to be able to set up a windowless air conditioner. This makes it ideal for even the most basic DIY-er to set up and use.
Affordable
Many windowless air conditioners are a more affordable option than window units or inverter air conditioners. This makes it possible to add a windowless air conditioner to that room in your house that can never seem to get completely cooled from the central air conditioning system.
Cons
Not Always Energy Efficient
Many of the windowless air conditioners aren’t the most energy-efficient options. This can cause your utility bill to increase if you’re not careful, so make sure you utilize the unit’s sleep timer or other programmable features to save as much energy as possible.
