When to have a portable air conditioner?

First of all, if you want to buy a portable air conditioner you need to know that they aren’t for the larger rooms.

You will need one when you want a mobile room cooler that is effective for rooms under 500 sq.ft.


The advantages of portable air conditioners are the mobility and the price.best portable air conditioner

They are also easy to install, but they also have some disadvantages too.

Some portable air conditioners can also dehumidify the air.


Portable air conditioners are a bit louder than other types and they have water that drains into a tank. You will have to empty this tank once it’s full.


Once you know what you are going to have, we will explain how we analyze the overall quality of each products.


What is BTUs?

Stands for British Thermal Unit. The higher BTU, the quicker your room will be cooled down.best portable air conditioner

While it seems that bigger is better, that’s not all true with AC units.


A unit that’s too large for the space will cycle on and off too quickly to cool and dehumidify the air properly.


So we didn’t research just for the 350-450 sq.ft. rooms, we did research for the 8000 BTU ones for 150-250 sq.ft rooms too.



  • Add 2,000 ~ 4,000 more BTU if the portable AC unit will be in a kitchen or hot rooms.
  • Add more BTU if you live in a hot climate, or if there are more than two people in the room.
  • Increase BTU  by 10% for sunny rooms with lots of windows.
  • Decrease BTU by 10% for deeply shaded or naturally cool rooms.


If the BTU is too low, your room will not be thoroughly cool, so we recommend higher BTU ones.


Just like any air conditioners, we will need some ways to remove the water removed from the air.


Ways to dispose of the moisture

  • Drip Bucket: condenses the moisture into a bucket, you will need to empty it every day or two.
  • Drainage Hose: route the water out the window or into a drain, so you don’t have to empty a bucket.
  • Self-Evaporating: releases moisture in the form of water vapor that’s mixed with the heat exhaust, so there’s only one exhaust hose and no buckets to empty. Only use a self-evaporative unit if you’re venting to the outdoors, never vent moist air into an attic or crawl space.


Most of the top rated portable air conditioners also come with a remote control.


Energy Efficiencybest portable air conditioner

Another thing we need to consider is the energy efficiency ratio (EER).

The EER is the ratio of the cooling capacity ( BTUs per hour) to the power input (in watts).


The higher the EER rating, the more efficient the air conditioner.


What is CFM airflow?

Cubic Feet per Minute. The volume of air moving through a ventilation system.


How to know which one is the best portable air conditioner?

We researched for Cooling Power, Noise, Features, Durability, Energy Efficiency.

Cooling Power

The more BTU number, the better for us. You better have some excessive BTUs than lack of it.

Also keep in mind that only BTUs can’t really measure the real cooling power of the unit, we need some reviews too.


Since one of the disadvantages is about the noise, we will find the quietest one.


We will find units with remote controls and units that has Self-Evaporating function.


Since there are no information about the materials, we will analyze the unit’s durability through customer reviews.

Energy Efficiency

The less power you use to cool the room, the better.

Among the top rated portable air conditioners under $400, this unit is the most cost effective one, and we will explain about it.


All questions about the product

Why it’s the best portable air conditioner?

Although this unit has 12000 BTU which is not the highest one ( the highest one has 14000 BTU and it costs less than $400 ),  the highest one seems to has lower overall quality. It doesn’t have much lifespan and not as durable as  Honeywell MN12CES.


Also the highest BTU one has no vertical adjustment on the output vents.best portable air conditioner

And yes, more BTU doesn’t always mean more cooling power in the real situation. You will need to test it.


So after we researched it seems like Honeywell MN12CES makes the coolest room with the longest average lifespan we analyzed from customer reviews.


About the noise, we couldn’t find any model that could generate less noise than 53 dB, which is noisier than a fan but not so irritating.


Have we analyzed other top portable air conditioners?

Yes and we concluded that the overall product quality compared to price is not as good as Honeywell MN12CES.


My room is only 250 sq.ft., is it bad to have a 12000 BTU AC unit?

There are some customer reviews about how their room size is about 230 sq.ft.

They said that the room is cool enough and they think it’s less expensive to run. So there should be no problem.


How do other websites think about this ac unit?

We took a look at every sites there and they mostly recommend this unit. Some say it is the best portable air conditioner.best portable air conditioner


After all these information, we still need some proofs here, so let’s move to the next process.

Next process : portable air conditioner reviews.



Reviews from all around

Productreview.com Review

I was reluctant to buy a portable air-con after reading all the negative product reviews for all brands. Got a good price for this one, was assured it would cool one room (and one room only) and they were right. So far so good, it is great and has got me through this hot summer. Yes its noisy as it cuts in and out but you get used to the background noise. I like the look of it too. Can’t move it up the stairs as its a bit heavy (tempted to get another for the bedroom) but so much easier and cheaper than getting a fixed air con in the wall.

  • Efficient cooling. Will take the temperature down from 80 to 70 in two to three hours.
  • Three functions for the price of one. This system offer three functionalities: cooling, dehumidification, and fanning.
  • Smart auto-evaporation system. This system eliminates the need for emptying water from the unit.


  • Loud operations. Expected for a portable AC unit – but we feel that the manufacturer could have made the unit quieter than it is.


Bestportableairconditionerratings.com Review

Honeywell is a well-respected manufacturer and has done a great job designing this machine. If overall noise level is a major concern when purchasing an AC, then this unit may be what you’re looking for. That alone may be worth it to some, but if you can deal with the noise there are a few other single hose manufacturers that perform just as well but at a lower price.


Amazon.com Reviews – Click here

Many reviews claimed that they also researched for the best portable air conditioner reviews and they finally decided to buy this one. Honeywell MN12CES is one of the highest rated best portable ac units with 500+ customer reviews and the positive reviews are usually upvoted to be helpful more than negative ones.


Most of the reviews also mentioned about the cooling power of the unit. They are satisfied that the product has fulfill their expectations.



Review conclusion on Honeywell MN12CESbest portable air conditioner

Majority of the reviews are about how Honeywell MN12CES is a powerful system that offers fast cooling within a short time.


The disadvantage of this unit seems to be the noise level which we also can’t find any portable air conditional that produce less volume than 53 dB.


By considering both the advantages and the limitations of this system, it is fair to give it a high rating.

After all, this is one of the best seller portable air conditioners on Amazon.com

You will want DELLA 048-GM-48266 when you have a small room and want to save some money.

This is like the degraded version of Honeywell MN12CES with the cheaper price, but still useful.

Prosbest portable air conditioner

  • Great value unit, probably the cheapest in its class

  • Multi-direction louvers for control of cool air flow
  • Eco-friendly design


  • New unit in 2016 with limited reviews (those so far are good though)

These two are the most cost effective portable air conditioner for their price.
