For a reasonable price, it packs quite the punch at 14,000 BTU. It’s sleek, stylish, efficient and eco-friendly. And the great thing about it is that you can also use it as a portable heater during winter.
We also talk about a few other alternatives below, but for most people who are looking for a reliable portable air conditioner, Honeywell MM14CHCS is our top pick.
At 14,000 BTUs, Honeywell MM14CHCS easily cools areas up to 550 square feet.

When you purchase Honeywell MM14CHCS, the box comes with everything you need – which includes a flexible exhaust hose and an easy-to-install window venting kit. You can easily remove the window vent when the AC is not being used.
It has fairly powerful air flow at 265 CFM (Cubic Feet Per Minute).
Despite being a fairly heavy-duty portable air conditioner, Honeywell MM14CHCS runs pretty quiet. It’s sound output is only 54 dbA.
It’s no bucket, no-drip design uses auto-evaporation system – which lets you continually operate the AC for hours without having to drain water or empty a bucket.
It’s 12,000 BTU heat pump will keep you warm during the winter as well. The heat pump covers area up to 400 square feet.
What “power” portable air conditioner do I need?
Before we move on to exploring other alternatives to Honeywell MM14CHCS, I want to briefly talk about how the “power” of an air conditioner is determined and what size/power air conditioner you need.
The cooling power of an air conditioner is measured in British Thermal Units (BTUs). Generally speaking, a BTU is the amount of energy needed to cool or heat one pound of water by one degree Fahrenheit. In air conditioner (AC) lingo, however, a BTU measures the amount of heat an AC unit can remove from the room. Therefore, the size of your area determines how many BTU- air conditioner you will need.
You don’t want a very low BTU – since it will be running constantly to get to your comfort zone. When an AC is underpowered for space, it’s not only not-energy-sufficient but it will not quite cool the space to your comfortable range. And, the air conditioner unit might burn out sooner too from the constant uphill battle.
On the other hand if the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. It is important to get a properly sized unit that will remove humidity effectively as it cools.
In order to figure out the right size portable AC unit for your space, do the following:
1. Find the square footage of the area to be cooled. To get the square footage, simply multiply the length of the space by its width. So, if my space is 10 feet wide and 16 feet long, your area is 160 sq. ft.
2. Then measure your square footage against the following chart from Energy Star. So, in my case (160 sq. ft. ), I will need a 6,000 BTU unit.
|Area To Be Cooled (Sq. Ft.)||Capacity Needed (BTUs)|
|100 up to 150||5,000|
|150 up to 250||6,000|
|250 up to 300||7,000|
|300 up to 350||8,000|
|350 up to 400||9,000|
|400 up to 450||10,000|
|450 up to 550||12,000|
|550 up to 700||14,000|
|700 up to 1,000||18,000|
|1,000 up to 1,200||21,000|
|1,200 up to 1,400||23,000|
|1,400 up to 1,500||24,000|
|1,500 up to 2,000||30,000|
|2,000 up to 2,500||34,000|
You also want to adjust your capacity based on the space occupancy and environment. For example, if the room is very sunny, you should increase the BTU capacity by 10%. Similarly, if the room is very shaded, you can reduce the capacity by 10%. However, there is no need to get too hung-up on getting exactly right. As long as you are not too off, you should be good to go.

Portacool PAC2KCYC01 Portable Air Conditioner
The Best Evaporative Cooler
When you need something heavy-duty, and if you are in a drier climate, Portacool PAC2KCYC01 is your portable Air Conditioner. It can lower temperatures up to 30-degrees Fahrenheit and works well up to a 700 sq. ft. space. That is pretty chilled!
It is an evaportive cooler, which means that it cools air through the evaporation of water. In other words, it reduces the temperature of dry air through the phase transition of liquid water to water vapor (evaporation).
Keep in mind that evaporative cooling increases humidity and is well suited for dry climates.
The unit is made of a durable one-piece, rust-free, leak-proof molded polyethylene housing.
It is maintenance-free for the most part. However, evaporative coolers require a constant supply of water to wet the pads. There is a convenient water level sight tube and sump drain, as well as a 3/4-inch water hose connection for longer running.

Whynter ARC-14SH Portable Air Conditioner cools really well. At 14,000 BTUs you can easily cool your average 500 sq. ft. of space.

It’s equipped with Dual Hose Exhaust for Optimal Airflow and Efficiency.
The “Dual Hose” system is an extremely important part of portable air conditioning. You can buy a portable Air conditioner with either a single or dual hose system. A single hose system uses just one hose to pump hot air out of the building. The problem with this is that this reduces the air pressure inside your home, and, as a result, hot air from the outside to come in through cracks in doors and windows.
On the other hand, dual-hose units like Whynter ARC-14SH, cool the hot air that’s already inside the house and return it to the room from where it came to begin with. So, it is essentially recyling the indoor air and not dealing with cooling the outside air. To keep itself from overheating, a second intake hose draws in air from the outside to cool the unit and then pumps it right back out again.
Whynter comes packed with everything you need to get it installed and running right out of the box including – a remote control, plastic window kit, two exhaust hoses, carbon air filter and washable pre-filter.

How to install a Portable Air Conditioner
Portable Air Conditioner Maintenance
Read the instructions carefully regarding cleaning and replacing your air conditioner’s filter. Regular cleaning not only helps your filter last longer but also allows the air conditioner unit to work more efficiently. You might have to clean the filter more often if you live in a dusty environment or have pets and kids.
Even though portable air conditioners do not require permanent installation, they do need to vent out the condensed hot air. Most portable air conditioners come with an easy-installation window kit or venting kit.
You want to pay attention to the environment of the room where you are placing your portable air conditioner. A dirty or dusty room has small particles that can find their way into the units motors, eventually clogging them – or causing mechanical or electrical problems. Also, if you live in a very humid area, the air conditioner unit will absorb all the excess moisture thereby producing excess liquid. You might want to consider installing a drain tube so that you don’t have to drain the air conditioner often.
You should make the habit of cleaning the exterior of your portable air conditioner unit with a clean, damp cloth on a regular basis. Be sure to turn off an unplug the unit before you wipe off the exterior. Avoid chemicals and detergents that can be abrasive.
Your portable AC unit will work more efficiently if you keep its condensor coil free of grime, dirt and grease. If the coil is looking grubby, use coil cleaner to keep it nice and clean. Also, if you see any ice build-up on the coil, it needs to be defrosted. Some units come with self-defrosting mechanism that will prevent any frost build-up. But if you keep seeing frost build up, it might indicate an issue with the unit itself – you need to get it checked out.
At the end of the season, be sure to store your portable AC unit properly. Drain all water from the unit and make sure that the unit is completely dry. Pack it in a box and store it in a dry location where water or moisture is not likely to cause any damages.
How Is The Water Handled?
Portable air conditioners remove moisture from air thereby producing water that needs to be drained in some way. Depending on the type of unit you purchase, there are several ways the extra water gets managed.
Common portable air conditioner units have buckets inside them that collect excess water. This bucket needs to be emptied on a regular basis based on manufacturer’s guidelines and your usage. You will have to plug in the stopper or turn the unit off, empty the bucket and then replace it before the cooling process starts again.
Most of the portable AC units come equipped with a drain port where you can attach a drain hose and dump water continually into a drain or some other location.
Some models are equipped with condensation pumps to pump the water out. The pumps force the water through the hose to drain out of the window.
Fully self-evaportive models evaporate all moisture themeselves – so there is no need to drain any water out. These units are very popular since their operation is hassle-free and they can be left unattended for a longer period of time.
Our pick for The Best Portable Air Conditioner is Honeywell MM14CHCS. It’s a solid, durable, multi-purpose AC unit that you can use year-round by using it as a heater during the winter months.
If, for some reason Honeywell MM14CHCS does not fit your needs, our next best pick, Whynter ARC-14SH, is an excellent choice.
