What is the Difference Between Single-Hose and Dual-Hose Portable Air Conditioners

By now, you already know that portable air conditioners come in two hose configurations – single and dual.

What is the difference between the two?

First, let’s discuss what exhaust hoses do and why they are important.

A Portable air conditioner must be vented via a window or wall to cool a room. Once you have the AC positioned where you’d like it, you must create an opening through the window or wall that will allow the exhaust to vent hot air out of the room.

Why is it necessary to vent your portable air conditioner?

It’s necessary to vent portable air conditioners because they extract hot air. This warm hair must be exhausted outside and cool air drawn into the unit for it to cool your room.

When you buy a portable AC, the window kit is usually included. If it’s not, you’ll have to purchase it separately.

You can install your portable air conditioner in any position as long you can vent it through a window, wall, ceiling or door. The most common material used for venting portable ACs through casement windows is Plexiglas.

The best way to vent the hot air to the outside using Plexiglas is by cutting it into the size of the window. You also need to cut a 5-inch hole and set it over the open window. This way, the portable AC will vent the hot air to the outside without interfering with the amount of light coming through the window.

So, what is the difference between single-hose and dual-hose portable air conditioner?

Single Hose Air Conditioning Units

ngle Hose Air ConditionerThe single hose design uses a compressor to power the cooling system and pulls warm air from the room.

Single-hose portable ACs removes air from within the room and expels warm air and moisture through the hose and out of the house. This creates a negative air pressure because when the air is continuously being pushed out of the room, the warm air that seeps into the room through the doorway, cracks, and holes attempts to replace the “missing” air.

In this case, the unit has to work much harder to keep the room cool, which is why single hose portable ACs are less efficient than dual hose portable ACs.

However, these types of air conditioners are still useful and provide ample cooling for most spaces.

If you decide to choose a single hose unit, you need to keep some things in mind before you install and start using it.

  • Single hose portable air conditioners are temporary cooling options. So, they’re ideal if you don’t want to install an air conditioner permanently in your room. Moreover, installing a temporary portable air conditioner allows you to move it to other areas of your home that need cooling.
  • You need to determine the right BTU rating for s single hose unit to work effectively.
  • Choose a unit with high BTU ratings if you’ll be using it in a room with computers or even a mini-fridge.

Dual Hose Air Conditioning Units

Best Dual Hose Air ConditionerThis type of air conditioner utilizes two separate exhaust hoses, one that draws air into the unit and one that removes the warm air to the outside of the home.

So, in the process of cooling the air from the room, the unit heats up, but the intake hose pulls air from outside the home to cool it down.

One of the reasons why a dual hose portable air conditioner is much more efficient than a single hose unit is its ability to eliminate negative pressure. This is why it cools the room efficiently and quickly without having to work as hard as a single hose unit.

Another advantage of using a dual hose design is that the lifespan of the unit’s filter is increased. In single hose designs, more unfiltered air enters the unit, shortening the length at which the unit’s filter removes allergens from the expelled air.

When choosing a dual hose portable air conditioner, make sure you compare the BTU, EER ratings and manufacturing quality. These will help you determine the most appropriate model for your home.

Features of Portable Air Conditioners

Apart from the dual hose design, some extra features are usually available in most air conditioners that would improve efficiency and user experience. When you go shopping for a two-hose portable AC, keep these features in mind.


Different models come with different types of thermostats. Modern ACs feature digital thermostats that have a LED display, showing you the preselected the temperature and the current room temperature. The LED display offers convenience and accuracy while the digital thermostat maintains a more consistent temperature in the room.

Most of these thermostats also come with an automatic shut off that turn the AC on and off depending on the temperature variations.

Basic models, on the other hand, come with mechanical thermostats – a typical dial button which you use to select your preferred temperature setting. These thermostats are less-convenient because you have to choose the temperature setting manually.

Adjustable fan speed

The different fan speeds allow you to select the rate at which the unit cools your room. Some air conditioners have two speeds (low and high) while others have three (low, medium, and high).

If the room is too hot and you want cool in the shortest time possible, you can select the high speed. If the room is relatively warm and doesn’t require too much cooling, choose the medium speed. The low speed is used when you want to maintain a certain temperature over a specific period.

Keep in mind, the fan speed you select affects the level of noise produced by the unit. The higher the speed, the louder the unit.


Just like other home appliances, air conditioners come with remote control. You can use it to adjust the temperature setting, fan speed and select the different modes. If you can’t always find your remote when you need it, you can choose a unit that has a magnetic hold on the side that stores the remote when it’s not in use.

Programmable Timer

A timer is intended to help you to save energy by allowing you to schedule the unit to turn on/off depending on when you need your room cool and when you don’t. While timers can only be set in a one-hour interval, they can go up to either 12 – 24 hours.

Air direction control

Sometimes you’ll need to customize the air flow and direct it to specific zones in your room. The adjustable louver lets you direct cool air to the areas you need it most. This is important because you get to eliminate hot spots in your room.

Energy star rating

Energy efficiency ratio is a feature that you must give some thought because it will affect how much you spend on energy. However, units that are energy-star rated are 15% more efficient than units that are not energy star rated.

Filter types

An air filter is what ensures the unit functions smoothly as intended. It’s important because it keeps dust, dirt, and allergens out of your home.
The two different types of air conditioning filters are standard and washable.

Standard filter is replaceable and used for a specific time. They are usually replaced when the time elapses.

Washable filters can be used for an extended period. They are more durable and can withstand many washes.

Things to Consider When Buying Portable Air Conditioners

It’s crucial that you choose the right portable air conditioner for your home. A perfectly-sized unit will work in the space you have, not only to meet your cooling needs but also at a cost you can manage.

Here are some of the boxes your new air conditioner must check before you can install it in your room.

Properly Sized.

You can buy a portable air conditioner with the intention of keeping it in one room or moving it from one room to another. Depending on how you intend to use your AC, it must have the right capacity to cool your room.

The BTU rating of an air conditioner determines its cooling capacity. If you have calculated the size of the space you want to cool, then it’s easy to find a unit with the right BTU rating.

Portable air conditioners with high BTU ratings are considered to be powerful and work efficiently in large rooms. A lower BTU rating means the unit is less powerful and ideal for a small room.

Keep in mind that power equals price. A higher BTU means the AC will be likely more expensive. If you have a small room, here are some of the smallest portable air conditioners.

It’s important that you choose the right BTU rating for your home so that you avoid wasting energy and money. An oversized or undersized unit will not cool your room efficiently.

Here is a table that will give you an idea of the number of BTUs you need for the specific room size.

Keep in mind that other factors may affect the number of BTUs required in a room. For instance, the type of insulation in your home will significantly impact the BTUs you need. If the insulation is poor, then it’s a good idea to choose a unit with a slightly higher BTUs rating.

Easy to Install, Position and Use.

Portable air conditioners work by extracting hot air from the room and taking in cold air from the outside. For this to happen, an exhaust hose needs to be set up through an opening to the outside.

Why is this important? Because the exhaust hose and the location of the window will determine where you place your unit.

The easiest way to vent portable air conditioners is next to a window. Since most models come with a window kit, all you need to do is set it up and plug the unit a few feet from the window.

The process is a little different if you want to install the unit in another room or away from the window where the hole that connects the unit to the outside is created. In this case, you have to consider the maximum width of the window kit. Some kits may extend to your preferred location, and others may not. If it doesn’t extend to the location where you want to place the unit, you can purchase an extension hose or vent kit that will allow you to position the unit in your preferred spot.

Remember, installing the unit close to a window and reducing the length of the hose increases efficiency.


While the initial cost of a portable air conditioner is a little expensive depending on the type of unit you have bought (here are the cheapest portable air conditioners), the maintenance cost can be way more expensive if you don’t take care of your unit properly.

This is not to scare you off, but to inform you that these units require periodic maintenance without which they’ll get faulty or work inefficiently.

One of the main maintenance that will require most of your attention is draining the collected moisture. If you have purchased a full self-evaporating air conditioner, then it’s not something you have to worry about. If your unit has a drain hose or an internal bucket, you’ll have to drain the water from time to time.

Next is cleaning or replacing the filters as directed by the manufacturer. The type of filter that comes with your AC determines whether it needs to be washed or replaced. Find out from the manual how long the filters should last and how often you’ll need to replace or clean them.

Lastly, you have to defrost the unit fully if ice builds up on the coil. Air conditioners freeze up for various reasons. The most common cases are low refrigerant and improper fan operation. Depending on what the case of the problem is, you should be able to fix it to continue enjoying the services of the device.

How much Noise does it Produce?

Like any machine that generates airflow, portable air conditioners also create noise in your space.

If you prefer a silent indoor environment, you may want to choose a quiet window AC. The decibel rating is what determines the noise level of an air conditioner. The higher the decibel rating, the louder the AC.

Some manufacturers will indicate the decibel rating on the product specification. Compare the different models and chose a lower decibel rating. If the decibel rating is not included, read other customer reviews to find out more information about the noise level of the unit. If the reviews are positive, then you can consider it, but if the reports are negative, look for another model.

The recommended decibel rating for a quiet portable AC is below 55 dBA. Anything more than this will be loud and make your home uncomfortable.

Is it Energy Efficient?

If you want to lower your cooling bills, you need to consider the energy efficiency of the unit you want to use. An energy star rated unit can help you save up to 30 percent on your total monthly cooling bills.

The Energy Efficiency Ratio (EER) will help you determine whether or not an AC is energy efficient or not. A higher rating means it’s more efficient while a lower score means it’s less efficient.

Some air conditioners have an energy saving mode. This feature allows you to program the unit the maintain preferred temperature setting without using a lot of electricity.

Wrap Up

We hope that you’ve gathered enough information from this guide that will help you choose the best dual hose portable air conditioner for your home. Like mentioned earlier, while dual hose units are more efficient than single hose units, don’t make the hose configuration a priority than the cooling capacity and energy efficiency of the AC. Also, make sure you have selected a unit that is features-packed so you can get the best out of it. Lastly, read the manufacturer’s guidelines so you can use it and maintain it as intended.
