How Do Portable Air Conditioners Work?

Portable air conditioners are designed with a standard window venting kit that repels exhaust. Most units are equipped with either one or two hoses that filter out hot air and cool the air inside the room. Generally, most models are constructed with some type of hose-based system.

In single-hose units, the hose pulls warm air present in the room into the unit, where the air conditioner’s motor cools it. On the other hand, dual-hose models suck in the fresh, cool air from outside your home and circulate it, while the second hose filters out the warm air at the same time.


What Size Portable Air Conditioner Do I Need?

When it comes to choosing the right air conditioner size, BTUs or British Thermal Units are the most important thing you should consider. While there are other characteristics and features to take into account, selecting the right BTU for your environment, needs, and room is the most important decision.

As a rule of thumb, a portable air conditioner needs around 20 BTU for one square foot of floor space. To measure the square footage of the room, you’ll need to multiply the width of your room by the length. Some reliable BTU estimates include:

  • 10,000 BTU for 300 square feet or less

  • 10,000 to 14,000 BTU for 500 square feet

  • 14,000+ BTU for rooms over 500 square feet  

How to Choose a Portable Air Conditioner

With so many different technologies and products available in the market, choosing the right air conditioner can be extremely confusing. However, there are some factors that can make or break your decision. Some of these considerations include:

User Interface

Modern portable AC models are designed with touch panels, Wi-Fi capabilities, and remote controls. Make sure you choose a unit that’s easy to use and boasts useful features.

Energy Conservation

This feature is important for two reasons. Firstly, an energy-efficient unit lowers energy consumption and helps fight the present climate crisis. Secondly, models with low energy efficiency result in higher electrical bills. 

It’s important to remember that low-quality units are usually energy inefficient.

Charging Power

For units that run with battery power instead of electricity, charging capabilities are incredibly important. If you’re leaning towards a battery-powered model, make sure it features a high power-retention ability. It’s advisable to stay away from models with low charge times.

Filtration Capabilities

Although some portable air conditioners only cool the air in the room, there are some models that filter and cleanse the air as well. While this is not a must-have feature, it’s still a beneficial one to have.

Portable Air Conditioner Pros and Cons

To help you decide whether a portable air conditioner is the best choice for you, we’ve listed the pros and cons of this appliance. It’s advisable to consider both aspects before you invest in a unit.


At its core, a portable air conditioner offers the benefits of air cooling without the noisiness and high costs that come with traditional AC units. Some of the main pros of this appliance include:


A portable air conditioner can significantly cut down your costs. Central air conditioners usually use more energy than portable units. Even if your home is already centrally air-conditioned, adding portable AC units to a few units can seriously drive down costs.

No Installation Required

With a portable model, you just need to unpack, plug it into a socket, and switch it on! This helps prevent the whole hassle of hiring a technician to drill the walls and install the unit in your home.

Easily Moved From One Place to Another

Due to its portability, you can easily use your portable unit in all the rooms of your house. You can place it in the bedroom at night and move it to the lounge if you have friends over the next day. You can also store it away safely during winters if you want some extra space in your room.  


Every coin has two sides. Some of the drawbacks of a portable air conditioner include:

Unwanted Noise

The most important disadvantage of a portable unit is that it produces significant noise. So, if you’re someone that’s easily irritated by noise, then this appliance may not be the best option for you.

Midea MAP08R1CWT

Drain Tanks Need to Be Emptied Regularly

Some models are designed with tanks to store the water that’s produced during the cooling process. You’ll have to empty and clean these tanks regularly to prevent them from leaking and overflowing in your room.

Types of Portable Air Conditioners

There are three different types of portable air conditioners, which are as follows:

Monoblock ACs

Monoblock portable air conditioners can further be categorized into two types:

Single-Hose Monoblock AC

This product is the simplest and quickest to use. The entire air conditioning mechanism is designed in a single unit that’s mounted on wheels. This auxiliary air conditioning system can easily be moved from one room to another, but it requires drainage.

Dual-Hose Monoblock AC

As the name suggests, these units feature two hoses. One hose collects outdoor air, while the other releases hot air. Basically, this unit freshens ambient air without bringing hot air from the outside and without using pressure, thus consuming less energy.

Split Portable Air Conditioners

Split portable air conditioners function exactly like monoblock units, but they’re designed with two separate components. The condensing and compression component is installed outside your home, while the portable ventilation unit is placed indoors. However, both components should be connected with a flexible hose. 

The main benefit of these units is that the portable ventilation unit is incredibly lightweight and generates less noise.

Costway Portable Air Conditioner

Self-Evaporating Portable Air Conditioner

These non-drainage units are actually coolers that work by condensation. They’re not really air conditioners, but they are lightweight, affordable, and ideal for cooling small spaces. However, they produce quite a bit of noise and are ineffective in rooms measuring over 15 meters square.

How Do These Compare?

For people who have never bought a portable air conditioner before and are just starting their research, it’s important to know that there are several different types that function differently. Let’s see how they compare:

Portable Air Conditioner vs Window Unit

One of the main advantages of a portable unit is that it’s incredibly easy to install. Due to the unit’s portability and mobility, it can easily be moved from one room to another, depending on which area needs the most attention. While a window unit is fixed in one spot, a portable model can be moved from the bedroom upstairs to the study downstairs if the need arises.

Furthermore, a window unit is placed almost entirely outside of your room, which can be an advantage to people who like reduced clutter. A window AC is also more energy-efficient than a portable one, which means that it offers more cooling power per BTU.

Dual Hose Portable Air Conditioner vs Single Hose

Single-hose units significantly cut down on energy bills, while dual-hose air conditioners offer greater performance and better cooling capabilities. Since the former is designed with only one hose, these appliances are usually far cheaper than the latter. Single-hose units are also less likely to offer the same additional features, like air purification and filtration.

A big advantage that dual hose units have over their single-hose counterparts is that they’re able to cool a room much more quickly. However, they are also more expensive and often consume more energy than single-hose systems.  

Evaporative Coolers vs Portable Air Conditioners

Unlike portable units, evaporative coolers are not designed with an exhaust hose and can be used outdoors for year-round climate control. They’re the perfect patio heater companion and can be placed by the pool as well. Their ventless system further makes it easier to move them from room to room.

While you can use a portable air conditioner in almost any climate, an evaporative cooler's effectiveness depends greatly on the amount of humidity present in the atmosphere.


How to Install a Portable Air Conditioner

Most portable units are incredibly easy to install and can be installed in 10-30 minutes. Make sure that the unit is placed on a level floor about eight to twelve inches away from obstructions, such as flowers and furniture. 

Make sure you also check the user manual for the minimum clearance space required. Ideally, you should place the air conditioner near an electrical outlet and close to an outside window.

If you want to install a portable air conditioner, you can follow these steps:

1. Install the Included Adjustable Window Kit

The included window kits will work with almost all kinds of windows, including ones that slide up and down and to the side. If you have a traditional up-down window, then position the kit at the bottom and make sure that it fits the entire width of the window opening.

If the window kit's length is larger than the window opening, you’ll need to trim the kit down. However, if the kit is smaller than the opening, then you’ll have to use Plexiglass, cardboard, or plywood to fill the gap.

Once you’ve made sure that the kit is fitted properly and no sunlight or air is leaking through, close the window to secure the kit in place. The air conditioner might also come with screws that you’ll need to use to secure the kit more firmly in place.  

2. Connect the Hose

You’ll need to connect the vent hose to the unit’s back. If the AC does not have a connector in place, then install the connector before attaching the hose. Take the second end of the hose and attach it to the window exhaust connector, making sure that it’s securely locked in place.

3. Plug In the AC

It’s important to remember that an AC should never be connected to an extension cord or a power strip. Make sure that you plug the unit into a properly grounded outlet, restart it, and then power it on.

How to Use a Portable Air Conditioner

To help you understand how to properly use a portable air conditioner, we’ve put together some tips that will help increase the unit’s longevity, efficiency, and cooling ability. Have a look:

1. Make Sure the Exhaust Hose is Kept Straight

You’ll want to keep the number of kicks, coils, and twists in the hose that connects the kit to the AC at a minimum. Basically, you’ll need to keep the exhaust hose straight with minimal contortions.

2. Regularly Clean and Replace the Filter

You should change the filter in your AC regularly if you want to ensure efficient cooling and proper operation. This process is also essential for maintaining indoor air quality.

3. Close the Door

Portable units work best in closed rooms. Make sure that the door is closed if you’re using the air conditioner in a basement or bedroom, so excess warm air cannot enter and cool air can circulate continuously. Furthermore, it’s advisable to place the appliance in a corner where it cannot get any direct sunlight.

4. Switch Off Any Unnecessary Heat Sources

It’s better to eliminate all unnecessary heat sources. Electronic equipment and light bulbs can emit heat. Although it might not seem like a lot of heat, it still makes your air conditioner work a bit harder to keep the room cool and comfy. Thus, you can turn off lights, small kitchen appliances, computers, televisions, and other small sources of heat for more efficient cooling.


While a central air conditioner cannot be beaten in terms of overall power, more and more people are being attracted to the versatility, energy efficiency, and convenience offered by portable air conditioners. Hopefully, this comprehensive guide has helped you figure out which model best suits your needs!

People Also Ask

With such a wide range of models available in the market, choosing the best portable air conditioner is no easy task. To help clear away any queries you may have, we’ve answered some of the most frequently asked questions regarding portable air conditioners:

How to Vent a Portable Air Conditioner

You can vent a portable air conditioner through a window, ceiling, wall, or door. You can also use Plexiglass to vent your AC through casement windows. If you want to vent it through a window, you can follow these steps:

  1. Connect the unit to the exhaust connector.

  2. Attach the exhaust connector to the exhaust hose.

  3. Connect the venting window kit adapter to the window kit.

Why is My Portable Air Conditioner Not Cooling?

If your portable air conditioner is not cooling, check the filter to see whether it’s dirty or clogged. If it is, make sure you clean it thoroughly. It’s also advisable to look for and remove any intake obstructions. Lastly, check the exhaust hose for obstructions and make sure that it’s as short as possible.

How to Clean a Portable Air Conditioner

You can clean a portable air conditioner by following these steps:

  1. Unplug the air conditioner.

  2. Dampen a soft cloth with water and clean the cabinet. Make sure you don’t use a spray cleaner or a liquid to clean the unit.

  3. Use a soft cloth to dry it thoroughly.
