Air conditioning is a home amenity that can make a big difference in your quality of life. In some particularly hot areas, air conditioning is a necessity to keep family members and pets safe. But not all homes or homeowners need the same type of air conditioning system. For many users, a portable air conditioner that can move from room to room or be set up on a temporary basis comes in handy.

You can find a portable air conditioner for most rooms, although you should look for one that fits the size of your room to ensure it works efficiently. They also come in non-evaporative or evaporative designs. You may need a method to drain the condensation that accumulates. Many models come with a pan, tank, or hose to take care of any moisture.

Here are the best portable air conditioners to cool your home.

For less than half the cost of some of its high-end competitors, this unit cools rooms up to 250 square feet, can be operated through your smart home device or an app, and can be used as a fan, air conditioner, and dehumidifier.

The overall noise level is comparable to other portable air conditioners, but it can be particularly noticeable when switching from fan to air conditioning mode. You can set up an optimal temperature for when you sleep so that you don’t need to make adjustments, but the noise from the unit as it kicks on may be enough to wake you up anyway.

It still cools an impressive 250 square feet and has two settings. You can install a drain kit through a window, but it’s not necessary except in very humid climates. This air conditioning doesn’t have a quiet or sleep mode, so it can get noisier than some of its competitors.

This could be a good unit for small apartments, although closed doors would hamper its overall cooling power.

It even has a 24-hour timer and sleep mode so that the temperature will adjust according to your presets without the need to manually change settings.

This is one of the louder models available on the market, but the addition of the heating capacity may make it worth any extra background noise that the unit creates.

This is a pretty tall unit, although it doesn’t take up a lot of actual floor space. It comes in dark gray with a black control panel. If you prefer a light and airy look to your room, this high-tech-looking unit will stand out from your decor.

What to Look for in a Portable Air Conditioner


Portable air conditioning units are either evaporative or non-evaporative. As their names suggest, the main difference is in how the collected condensation from the air is removed. Evaporative units let it evaporate back into the air, while non-evaporate units collect it for disposal.

Non-evaporative portable air conditioners are the most common and require you to periodically drain collected condensation or set up a drain hose into a pan, tank, or outside. Dry air cools faster and more efficiently, so setting up this kind of portable air conditioning system will help your unit run better. If you live in a humid climate, it will be necessary to use a non-evaporative unit and empty the condensation when needed.

Evaporative units are less common and best for dry climates. They do not collect condensation but let it evaporate back into the air instead. If your air tends to be dry, this type of unit will be perfect for you.

Room size

One of the most important factors when choosing a portable air conditioning unit is the recommended room size. Generally, a higher BTU rating means that the unit can cool a larger room. The humidity, temperature setting, and layout of the room will impact the overall efficiency of the unit. Some styles are available in multiple BTU options so that the same great features can work in a small or large room, depending on the particular model that you purchase.

Condensation drainage

If you choose a non-evaporative portable air conditioner unit, you will need to find a way to periodically empty the condensation. Some units have a tank or tray, while others work better with a drain hose attached to an exterior window. The best setup for you will depend on your climate, how much condensation your air conditioner collects, and the layout of your room.

  • When should you choose a portable air conditioner over a window unit?

    While window-mounted air conditioners are excellent long-term cooling solutions, they tend to be heavier, harder to install, and less versatile than their portable alternatives. Portable air conditioners tend to be the better option if you need to be able to move your unit from room to room, or even between buildings.

  • How do you install a portable air conditioner?

    Non-evaporative portable air conditioners will need to be set up near a window or vent so that their exhaust hose has somewhere to pump hot air out of your home. These units usually come with a window adapter that will create an air-tight opening for the hose. Installation generally shouldn't take longer than 15 to 20 minutes.

    Evaporative portable air conditioners don't need to be hooked up to a window or vent, but they work best in a well-ventilated area. Keeping yours near an open window will prevent the room from getting too cold or clammy.

  • How do you empty a portable air conditioner?

    When the time comes to drain your portable air conditioner (which will vary depending on your model and how often you use it), you can empty the water tank manually by placing a pan under the unit and letting the water drain into it. If your unit comes with a drainage hose, you also have the option of attaching the hose and running it down a floor drain.
