Portable Air Conditioner Buying Guide

It is relatively easy to find a portable air condition in a store or online. But, finding a unit that cools the space that you need cooled, dehumidifies, and does so economically, is another matter. Knowing a bit about air conditioners and especially portable air conditions comes in handy when you go to spend your hard-earned money.

In our buying guide for portable air conditions we address the important issues will help you make a smart decision when you make your portable air conditioner purchase.

For the average customer, features like a dual-hose setup, a long list of accessories, references to testing, and power consumption ratings can be overwhelming. We hope to make that a little easier for you and assist you in make in smart choice when looking for portable air conditioners.

Ventless vs Portable Air Conditioners

A portable AC unit is a compact air cooling device which you move from place to place. This is different from central AC or a window-mounted unit, neither of which are portable.

While you will need someone to install your central air conditioning and even a window-mounted unit, a portable unit simply requires that you run an air duct to a window to exhaust hot air.

You can typically do this in ten to fifteen minutes! This is an air conditioner with refrigerant that generates heats as it cools the air. By exhausting the hot air from the unit, you cool your room, office, or other living work working space.

On the other hand, if you do not have a way to exhaust the hot air from your space or would rather not, then you need a ventless portable air conditioner. These units also have less power consumption as they simply blow air across a moist screen or other device to cool air.

These are not portable air conditioners in the strict sense of the word but get the job done in the best way and by providing cool air with less power usage and a lower light bill! This is often a smart choice to follow up on when what you want is cool air at the best price.

Ventless Air Conditioners

This sort of device cools the air by evaporation and is technically not an air conditioner. An older name for this sort of device is a “swamp cooler” and more recently they are called evaporative air conditioners.

Because this unit does not exhaust hot air outside of the cooled space, it is not an air conditioner. But it may be the best and smart choice for you!

Why Are They Called Ventless?

This is simply because they do not exhaust or vent air to the outside. This sort of cooling unit does not have a compressor nor does it use a refrigerant, unlike a true portable air condition. Therefore, a ventless unit does not generate a lot of heat that needs to be removed from the room. And, it uses substantially less electric power!

How Does a Ventless Unit Cool a Room?

These units rely on evaporative cooling. Evaporation of water lowers the temperature of the H2O as it changes from liquid to gas. A ventless system has a water reservoir placed at the bottom which gives it a low center of gravity and prevents it from easily tipping over. It uses a pump to pull water up out of the tank.

The water drips onto cooling pads or filter pads and a fan blows air from the room across these pads and back into the room. The passing air causes evaporation and cools the air.

A major advantage of this system is that it is much less complicated than refrigerant-compressor air conditioning and requires less energy. That means you will be paying less on your electric bill when you use one of these devices.

The downside of a ventless, evaporative system is that it cannot cool the air to the degree that a portable, window-mounted, or central air conditioning system can. You do not need to do a lot of testing to check this out. These are the best solutions in many cases and the smart way to cool a small space, especially in an arid climate.

What to Consider When Choosing a Ventless Cooling Device

The first thing to look at when picking the best device is the space that you want to cool. Then you need a unit with the cooling capacity to cool that space. When choosing a ventless air conditioner, make sure that the capacity of the unit matches the space you need to cool off.

Part of this is also the size of the water tank. An efficient unit will only cool your room as long as it has water in its reservoir! the best units have adequate reservoirs for several hours of operation.

Ventless Air Conditioner Features You Will Want

Modern units have remote controls, digital displays, auto-restart capability, and timers that you can program. Decide which of these you need and only buy a unit that has them. And, you will typically want a portable unit that you can move around a room or from room to room.

Because these cooling devices don’t need an exhaust hose or dual-hose, there is a lot less fuss and bother when you take them from room to room. If you will need to carry it up and down stairs, just having rollers is not enough.

You will need to consider size and weight and never carry it around with a full water tank! The only issue when putting this device in a room is having a close electrical socket.

If you need an extension cord, make sure that has the volt and amp capacity necessary so that it will not overheat! When you pick best unit with the best features like a hand remote, you will get the same cooling as window units or central air for the space desired. and for a lot less money!

A water tank capacity of seven gallons is enough so that you will not be continually refilling it.

These units are less noisy than a true AC unit. What you will want is something rated at 50 decibels or lower. and get a remote. It is the best way to make life a little easier in your air conditioned space!

Installation of Portable Air Conditioners versus Ventless Air Conditioners

Both of these devices are relatively easy to install. The ventless system only requires that you fill the water tank and plug it in. The portable air conditioner needs to be vented. These units come with the vent hose and attachment for venting through a window. Installation of these units rarely takes more than fifteen minutes.


When you are shopping for a portable air conditioner you will see these terms. What do they mean?

BTU stands for British Thermal Unit. Is the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit. For air conditioners, a BTU refers to the amount of energy needed to remove heat from the air. Air conditioners with higher BTU numbers are able to cool off larger areas than those with lower numbers.

Best Cheap Portable Air Conditioners

How many BTUs you need will depend on the volume of space you want to cool, how well the space is insulated, the outside temperature, and just how cold you want a space to be. Portable air conditions will have BTU ratings and should have information about the space they can cool off.

CFM stands for cubic feet per minute. It tells you how much air a fan or air conditioner will blow over a minute. While the BTU rating tells you about the capacity of a device to reduce heat, the CFM rating tells you about how well the unit moves that cold air around.

Both units are important in choosing a portable air conditioner. However, looking at the recommended amount of space to be cooled will is the best way relieve you of the obligation to go too deeply into BTU and CFM calculations!

Noise of Portable Air Conditioners

There is more going on inside of an air conditioning unit than with an evaporative cooler. So, AC units tend to be noisier. Look for a decibel rating and it will tell you if your unit is going to be making a racket or not.

At 50 Db rating is usually OK as it is about the amount of noise you get from your refrigerator or a quiet street. Every ten Db increase is twice as loud. 40 Db is the level of noise in a quiet library and 60 Db is the amount of noise in a busy restaurant. Aim for 50Db or less and you will be happy.


The point of having a portable AC unit is that you can use it in more than one location. Having wheels or castors is important and having a handle on top is great. Of you are going to be lugging the unit up and down flights of stairs, size and weight are big issues.


Portable AC units can be very inexpensive and they can be quite pricey. We suggest that you always consider what you need in terms of space to be cooled and how cold you want it first of all.

Then consider features like programmable controls, ease of operation, maintenance issues, and cost of operation as opposed to how much the unit costs to buy.

The fact of the matter is that if you buy a cheap AC unit that does not do the job or that you find difficult to use, you will have wasted your money. When you have decided what you need to have, then shop for price.

Specific AC Features

Automatic Draining System

This is an issue for portable air conditioners and not ventless systems. A window mounted AC unit typically drains outside of the building and central AC systems have automatic draining.

This is a nice feature if you can get in with a portable system. It lets you not worry about the warning light that tells you the tank is full! However, you need a place for the system to drain.

If your office or bedroom has no place for the drainage tube (called a condensate line) to go, you will be paying for feature that you cannot use. Units that give you both manual (drain it yourself) and automatic options are ideal.


This applies to ventless systems. An evaporative air conditioning system in an arid climate will not only cool off your living space but add necessary moisture to the air as well. Standard air conditioning systems take moisture out of the air as they cool it.

Programmable Thermostat

This is really nice feature that you should look for in both portable AC units and ventless units. Coming home to a cool bedroom at the end of a long day can be fantastic.

But, having to pay for the AC running all day is not such a great idea. Many systems can be programmed twenty-four hours in advance both to turn on and off and for specific temperature settings. This is both a convenience item and an energy saving feature that is worth paying a little more to have.
