It is also an excellent way to cool certain areas of your house or office and they can be easily moved around. Windowless air conditioning units are very useful in case your office does not have a good AC and you simply cannot stand the heat inside. These types of units can lessen your overall cooling expenditures since they confine the cool air to a particular zone or area.

A windowless air conditioner is energy-efficient, reasonably light-weight and inexpensive than huge window AC units – which require to be near a window due to their exhaust vent mechanism. I would just like to point out (so as not to confuse readers) that all air conditioning systems need to vented. So, if there are no available windows, then other alternatives like utilizing a drop ceiling or dryer vent is needed. For that reason, even if a windowless air conditioner is installed in your home or office, you should have it properly vented one way or another.

Another factor to take into account with window-type AC units is that they can leak water right outside your house or office. Although windowless air conditioners leak water as well, they go straight into a container which needs to be drained in order to avoid spillage. These two models that we are going to discuss are some of the best windowless air conditioners out there.

Haier CPRB07XC7 7,000 BTU Portable Air Conditioner with Remote Control

If you are searching for a compact, inexpensive, yet powerful heating and cooling solution to your room, then you may want to consider the CPRB07XC7 model. Its features include an adjustable thermostat which enables you to set the temperature to your desired setting for maximum comfort. Not only that, it can also be used as a space heater so you can stay warm during those cold months and has full-performance remote control that allows you to set the time, change fan speed and turn on or off the unit with just a push of the button. This unit is also an excellent choice if your home has outward-opening windows, as well as a terrific solution for those who have very hot rooms.

AP148D 14,000 BTU Windowless Portable Air Conditioner

I have read a review about this product wherein someone said that it would automatically turn off every half hour, but mine is turned on all day long and yet I have not encounted any problem whatsoever. Also, this windowless air conditioner is quiet compared to the fan that I used to have (which I threw after I bought this model).

The company even stated that their product eliminates about 99 percent of dust and other airborne substances that may cause allergies with the use of their Trane CleanEffects™ air filtration system. This is clearly an excellent feature for people who have problems with breathing or allergies, don’t you agree?

Each and every Trane Air Conditioner is built from materials which are checked and tested over and over again to guarantee its strength and high quality, and with the company’s determination to provide increased home cooling efficiency, you can be assured that the cost in keeping the air in your home clean and at the same time cool would decrease significantly.

To give you an idea about the various Trane air conditioners available in the market today, I have listed them down here:

Trane XL 20i

This unit is one the most efficient air conditioning unit out there and the rating of The Seasonal Energy Efficiency Ration is 20.00 at the most (made possible by its dual compressors). Basically, you have two AC units in a single machine – one for mild weather conditions and the other for extremely hot, scorching days. It also features a ComfortLink II communication technology which allows the key components of your system to “communicate” with each other to calibrate, configure and adjust automatically to ensure optimal performance. 

Another great thing about this model is that you can add a Telephone Access Module (optional), allowing you to control the AC unit in order to regulate various settings and receive updates via your cell phone. How cool is that, huh? This unit runs quietly and with several fans guaranteeing utmost comfort.

Trane XL15i

Of all the single stage units made by Trane, the XL 151i model has the lowest level of sound. Moreover, it is a good energy-efficient option for homes and offices due to its Seasonal Energy Efficiency Ration rating of 16.00.

Trane XR15

For homeowners who want to earn energy tax credits, the XR15 model is an excellent choice because of its Seasonal Energy Efficiency Ration rating of 17.00. Not only will you be able to reduce the cost on your electricity bill, but you will also be able to experience Trane air conditioners’ comfort.

Trane XB14

The XB14 has a 16.00 rating from SEER – meeting energy tax credit, as well as Energy Star requirements, allowing you to enjoy the quality and luxury of Trane air conditioners.

In case you live in an apartment or your house is not that big, it would be much more practical to have a small unit installed, and due to their ease of mobility, moving them around would not a problem. In addition, they are energy-efficient and less expensive as compared to large window and central units.

Furthermore, a small portable air conditioner is excellent for larger homes which have a large window or central AC unit. The upper floors in older homes sometimes do not receive the same temperature like the rooms in the main floor. So, this is an excellent idea to install a portable air conditioner upstairs, particularly since majority of people sleep upstairs (which is by the way pretty obvious).

Here are some small portable AC units I would recommend for those people who are thinking of buying one:

The first on our list is the Koldfront 8,000 BTU Portable Air Conditioner. What I love about this product is that it is energy-efficient (you can set it to run only when you need to cool off), has an ultra compact design (you can fit and store it anywhere since it is only 2 ft. high), all year round versatility wherein it can dehumidify the room when AC is not needed, features a self-evaporative system (there is no need for you to empty water since it has an automatic drain exhaust system).

Another small portable air conditioner that I like is the Sunpentown WA-7500M 7,500 BTU model. This product is ideal for small areas of up to 200 square feet. It has 2 fan speeds, directional air flow louvers, 8-hour timer, built-in water tank for constant water drainage, washable air filter, activated carbon flter to help get rid of odor and a self-evaportating system as well.

Last on my list is the EdgeStar 12,000 BTU Portable Air Conditioner and Heater. This product features a programmable thermostat that can be displayed either in Celsius or Fahrenheit and a heater functionality that you can use throughout the year. It also includes a window kit with an exhaust hose that can be extended up to 49 inches, 1 replaceable carbon filter and washable pre filter.

So, there you have it! You can do some research online for small portable air conditioner units if you want to. Just make sure to take the time in shopping around in order to find one that will suit your needs best.

I have compiled some of the models and their features. Here they are:

Carrier Performance Series 52MEU153 15,000 BTU Packaged Terminal Heat/Cool Air Conditioner with Electric Heater and Wall Thermostat Interface Capable

In my opinion, this is one of the best units currently available in the market. This model includes built-in protections such as an automatic restart mode after a power outage, freeze guard protection, self-check and correction diagnostics, better condensate removal mechanism, random compressor restart delay and an emergency heat mode for heat pumps.

Moreover, it is energy-efficent, has energy management and wall themostat capability, set point limits is programmable, troubleshooting is easy due its LED onscreen display and best of all, it comes with a complete 5-year limited warranty. What more can you ask for?

It also has built-in protections just like with the 52MEU153, user-friendly control features such as LED indicators, 3 fan speeds selection, easy-to-operate and large touchpad buttons and easy-to-read digital display.

Carrier Performance Series 52MQU124 11,400 BTU Packaged Terminal Heat/Cool Air Conditioner with Heat Pump, 3 Fan Speeds and Large Digital Display

There is nothing more to say about this model except that it is great. Just like with all other Carrier air conditioners, the 52MQU124 model has advanced fan technology and a dual fan motor design for quiet comfort. With its user-friendly and large, easy-to-read touchpad buttons, your guests can operate it without any difficulty. You can also perform diagnostics due to the built-in self-check and correction features. Now, that is something, right?

Carrier Performance Series 52MQU094 9,000 BTU Packaged Terminal Heat/Cool Air Conditioner with Heat Pump, 3 Fan Speeds and Large Digital Display

The 52MQU094 has the same the features as that of the other Carrier air conditioners – user-friendly controls, electronic controls, as well as built-in protection and energy-saving features. The application can be customized with accessories, has bi-directional air deflector, booster heating for heat pumps, fresh air ventilation (up to 65 CFM), and with universal fittings, replacement works are troublefree. Since it has LED onscreen displays, troubleshooting is a breeze and the condenser coil can be easily accessed for cleaning.
