Benefits of Portable Air Conditioners
Air conditioners are a savior to those living in hot weathered climates. Many people simply, cannot function without them.
There are many benefits to owning a portable air conditioner, including:
- Convenience of use – A portable air conditioner can be easily moved from room to room as it is not fixed to any specific area of your home.
- Easy set up – It also does not require any major installation as most portable air conditioners actually require minimal set up and are ready to use straight out of the box. If you are not a home owner, and you are worried about restrictions regarding installation of an air conditioner, then a portable air conditioner will suit your needs as it will require no installation to the building itself as it is a self-standing unit.
- More affordable than regular air conditioners – Portable air conditioners are also cheaper to purchase when compared to your conventional air conditioners.
- Despite similar cooling power – A great number of portable air conditioners also come with BTU’s matching those of traditional air conditioning units which means that you will not need to compromise on cooling power.
- Doubles as a dehumidifier – Portable air conditioners also serve a dual purpose, they can function as both an air conditioner as well as an air dehumidifier, so if you do live in humid climates, you should seriously consider getting a portable air conditioning unit.
- Versatile – Another benefit to owning a portable air conditioner is that if you are looking to just cool a small area then this portable option will be able to do just that as they do come in varying BTU’s to cater for the cooling of small spaces to large spaces.
- Save on utility bills – Portable air conditioners can also save you money on your energy bills as they can provide spot cooling for just the areas that require the necessary cooling.
- Portable – Another big benefit is the portability of the unit. Being portable, you can take these units with you on road trips, camping etc.
How many BTUs do I need?
To figure out how large of an air conditioner you need, first figure out the size of your room using this chart from the National Association of Home Builders:
< 2k sf
> 3k sf
Once you know the size of your room, the following table will give you a good reference as to how large of a capacity you need:
Room Size (square feet)
100 up to 150
150 up to 250
250 up to 300
300 up to 350
350 up to 400
400 up to 450
450 up to 550
550 up to 700
700 up to 1,000
1,000 up to 1,200
1,200 up to 1,400
1,400 up to 1,500
1,500 up to 2,000
2,000 up to 2,500
How We Picked
There are 5 major types of room air conditioners to choose from. These are Portable Air Conditioners; Window Air Conditioners; Through-the-Wall Air Conditioners; Ductless Mini-Split Air Conditioners; Packaged Terminal Air Conditioners (PTACs).
Portable air conditioners are mostly freestanding floor systems that work by cooling your room or office by pulling in fresh air, removing heat and dehumidifying it, and then returning it into your room or office while removing the hot air. It is important to note that to function properly, portable air conditioning systems must be configured to release hot air outside through a window or open door or upward through a drop ceiling opening.
Most of the portable air conditioners on the market today come with a window kit and exhaust accessories that allow you to easily set up your air conditioning unit. Portable air conditioners use a refrigerant to provide more cooling potential than most other outdoor cooling solutions. Setting up your portable air conditioner is simple and does not require any major installation.
The portable air conditioners that were selected for comparison for this review had to meet the following criteria:
- They had to be portable – for ease of use, no need for costly installations, and adaptability for use in different living areas in the home or office.
- We then looked at cooling coverage of the systems. We chose systems that had specifications to cool areas between 200 square feet and 400 square feet. This was done to ensure that a wide range of systems would be included in the review for smaller to larger homes or offices.
- We then looked at the BTU’s of the systems. We included portable air conditioning systems that ranged from 5 000 BTU to 14 000 BTU. Again this was done to ensure that a wide range of systems would be included in the review for smaller to larger homes or offices.
Our Top Pick:
The top pick is the Honeywell MN10CESWW 10,000 BTU Portable Air Conditioner. This is a beautiful air purifier unit and is capable of cooling areas up to 350 square feet. This unit can work as an air conditioner or a dehumidifier or a fan. It comes with its own remote control. Because it is portable it requires no major installation and it has four built in caster wheels for easy portability. You will also find in the box, a flexible exhaust hose and self-install window venting kit, which is removable when not in use. It is quiet during operation and can be used dual-purpose as an air conditioner and a dehumidifier at the same time. It has a powerful 10,000 BTU and can cool rooms up to 400 feet in area.
It has an auto-evaporation system which when in use can allow for long periods of unattended use without having to manually constantly drain out excess water. It has a programmable timer for this and LED panels. This portable air conditioner comes with a 5 year limited warranty.
Flaws (but not Deal Breakers)
This unit is not regarded as being the quietest portable air conditioning unit on the market, but a good trade off for this is the price and the value for money. The remote control that this unit comes with is fairly basic so it will not be able to display a digital temperature for you like some of the other units available today are able to do. The louvers on this unit are manual. This means that whenever you use the machine you will need to adjust the louvers yourself, by hand, to the angle that you want the cool air to flow to. Also when you turn off the unit you will need to manually close the louvers as well.
This unit does not also include a mesh to keep out bugs or rain while in use. There are units available for purchase that do include these items but at the sacrifice of other factors, such as price or power of the unit. The flaws of this portable air conditioner chosen to be our top pick are not deal breakers though, as this unit has many pros as mentioned above.
The step up pick has to be the Whynter 14,000 BTU Dual Hose Portable Air Conditioner (ARC-14S). It is the most powerful air conditioning unit reviewed here, with a 14.6 gallon water tank capacity. This is the most expensive portable air conditioning unit that we have reviewed here today. This unit also has a built in auto drain function for controlling condensation.
This unit also has a compact, eco-friendly design, which offers reduced energy consumption when compared to other air conditioners. It is portable with four built-in multidirectional casters. It has a dual hose exhaust which works by processing warm air from both the inside and outside environment and converting it into fresh air conditioned air. The used warm, humid air is then evacuated out of the room via the second hose.
This portable air conditioner has a control panel that has an LCD display, with different fan speeds to choose from and an easy programmable feature with on/ off pre-set times. There is also a pre-filter and odor-neutralizing carbon filter in the unit that provides fresh air conditioned air. A built-in safety feature is that is has a leakage current detection and interruption plug, which reduces the risk of fire.
The only reason that this unit was not our top pick is price. It is much more expensive than any of the other worthwhile units on the market.

How Portable Air Conditioners Work
The first air conditioner was designed on the premise of passing warm air over water cooled coils. It was a simple process. Air conditioners have, however, come a long way today.
Air conditioning systems work by transporting and delivering energy from one location to another. This does mean that when the air conditioner is cooling, as much of the heat as possible is withdrawn from the air in your room or office and then the heat is then transported to the outside and is subsequently released through a contraption called the condenser and also goes through a refrigerant cycle. The gaseous refrigerant is then drawn in by the compressor and is subsequently compressed until the temperature becomes very high.
The substance that is now very hot but still in a gaseous state (which is termed to be the refrigerant) is then pumped from the compressor to the condenser of the unit. A cooling process now occurs. This is where the fan enables the cooling down of the refrigerant which is directly aided by the outside air, which actually allows it to condense and return to a liquid state.
Now, the liquid refrigerant, which is still under a great pressure, is sent back into the evaporator unit which is located in the indoor unit of the machine.
It is at this stage that the warm air in the room is drawn in with the assistance of the fan and is then blown across the evaporator part of the unit. The heat in theory should now be removed from the air.
The air that has now been cooled down is at this point returned back into the room. The heat is now removed which results in cooled air. When the liquid refrigerant evaporates, the required heat is removed from the warm air in the room.
he evaporated and hence gaseous refrigerant is passed through the cooling cycle and into the compressor of the machine, where it is compressed again. Air conditioning units can also function in the opposite way as a heating unit. In the heating function of the unit, the cooling cycle is reversed which means that in this instance the heat is withdrawn from the warm air outside and released into the room by the indoor unit.
Should I invest in a portable air conditioning unit?
This all depends on your specific situation and your current needs. If you have a small area that requires cooling at certain times of the day then yes, a portable air conditioner will suffice. If price is a concern to you, then a portable air conditioning unit when compared to a traditional fixed air conditioning unit, will be cheaper in terms of outlay on capital and running expenses.
Will a portable air conditioning unit save me money?
Yes. As mentioned earlier, being portable means that you will be able to easily move the unit from room to room as is needed. Its initial cost to purchase is less than fixed systems with their installation costs, and it will save you on energy bills.
Do I need to buy a portable air conditioning unit for each of my rooms?
This will be dependent on the size of the portable air conditioning unit you purchase as well as on the layout of your home/ office area. If you have a more open plan living area and you purchase a high BTU unit then one will suffice. But again, this is specific to your own unique needs.
Wrapping it up
After extensive research we chose our top pick, the Honeywell MN10CESWW 10,000 BTU Portable Air Conditioner for the cooling power output it provides. It has very simple assembly and it is an aesthetically pleasing unit. It is a strong dehumidifier and is also cost and energy efficient.
