How Do I Choose a Dual-Hose Portable Air Conditioner?

There are certain characteristics or factors that make air conditioners stand out and give you a good experience. Let’s go over them so that before purchasing, you are able to make a note of all these features. 

Energy Efficiency

When looking for a portable air conditioner, you need to ensure it is energy efficient and does not require large amounts of power.

Make a note of the EER or Energy Efficiency Rating on each model you wish to consider purchasing. A high EER will ensure a smooth experience.

Overall Effectiveness

Dual-hose ACs perform better than single-hose ones since indoor air is not vented outside with the former.
They are capable of cooling a room better and quicker if their quality is excellent. This is particularly important to consider for larger spaces or rooms.  

Ease of Setup

Dual-hose air conditioners can be tedious to set up and operate. So when making your purchase, look for quality units to make this process as simple as possible as some of them usually come with some helpful tools. Consult your salesman with this too.  


Before making your purchase, keep in mind how large your room or space is so that you buy a unit accordingly. Some ACs are capable of cooling small spaces only. For this purpose, you can refer to the BTU rating, which indicates the cooling capacity of an AC.

What is a Dual Hose Portable Air Conditioner?

A dual hose portable air conditioner is an air conditioner that is operated using two hoses – one that brings in air from the outside and cools it down, and one that takes the hot exhaust air and expels it. Air conditioners with two hoses are noticeably more efficient than those with a single hose since one hose will necessarily have to work harder to perform both functions at once.

ASHRAE vs SACC Rating Systems and Why They Matter in Dual Hose ACs

Although the standard cooling capacity of the models hasn't changed, the Seasonally Adjusted Cooling Capacity (SACC) is lower than the previously accepted American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) rating.

The reason for this change and, honestly, confusion for many users is the actual vs. perceived cooling capacity of a portable AC.

You might already know that a portable air conditioner and a window unit of the same BTU might produce different perceived coolness in the room. The reason for this is the heat a mobile unit emits back into the room during operation.

Portable air conditioners are now rated with a new SACC rating (since 2017) to cover this issue. This grading is a couple of thousand BTUs lower than the previous (ASHRAE) one.

This distinction is crucial for users of portable air conditioners to differentiate the "claimed BTU" (ASHRAE) from the one you feel on your skin (SACC) when the unit actually operates in the room.

Top Brands in the Dual Hose Portable AC Space

Portable air conditioners are a specific market appreciated by many and despised by others (because of being less efficient than most window or wall-mounted ACs). However, some portable AC brands have been consistent in quality and customer care over the years. Below are two of them.


Whynter is a US brand located in Brea, CA. It generates more than $7 million annually, making refrigeration, outdoor living, and other lifestyle products. Their "Air Comfort" product category includes misting fans, mini-split units, dehumidifiers, coolers, purifiers, and portable ACs.

Its portable air conditioners cover single and dual hose units with a cooling capacity from 10,000 to 14,000 BTU. Whynter's mission is to make the lives of its users more convenient and build products that give you "one less thing to worry about."


Honeywell is a multi-profile manufacturing and technology company with divisions in various industries, including aerospace, buildings and cities, materials, retail, and safety.

The corporation licenses its brand name for various commercial and retail products and services, including thermostats, ACs, security safes, home products, and even paper shredders.

The brand's portable air conditioners consistently outperform on the market.

Price Points of Dual Hose Portable ACs

Portable air conditioners come in all shapes and sizes. Depending on how much functionality the appliance has and how complicated operations it can perform, the prices fall in specific ranges. The pricier the unit, the smarter options it has.

$300 - $500

Most standard portable units are in this range. At the lower end of this range, the appliances have lower BTUs (5,000 to 8,000) and only a few functions like cooling, fan, and dehumidification. They might not include a remote and don't usually look too modern or sleek.

$500 - $1,000

This is the price range where the manufacturers put more effort into the appliances, making them more modern and sleek, adding a led display, remote control, or smartphone connectivity.

If the previous price point units need a tank or a hose for drainage, these might have a self-evaporation functionality. Portable air conditioners in this price range also have a heating mode and can serve rooms of up to 1000 square feet.

$1,000 - $2,000

This category includes units with more than 10,000 BTUs or some intelligent functionality. These portable ACs usually have up to eight speeds, a built-in timer, air purification, and fancy modes like "natural wind."


This benchmark is either for higher BTU residential or specialized equipment. Most of the products here employ hospital-grade particle filtering with ULPA filters. They even use UV lights to reduce microorganisms in the environment.

What Size Dual Hose Portable AC Do I Need? 

Sizing the room for a portable air conditioner works the same way as it does for any other variety. However, as the units also heat during operation, you might need to buy a higher BTU unit to get the same effect as you would from a wall-mounted appliance.

First of all, you need to find out the square footage of the area the AC is going to work for. Next, you can either use the "AC power capacity" formula, a power/area chart, or a BTU calculator to estimate the AC size for your space.

Whynter ARC-143MX

Who Would Not Benefit From a Dual Hose Portable AC?

Although dual hose air conditioners prove helpful in combating the heat and keeping your house’s humidity levels under control, there are cases where they aren't the perfect solution.

No Venting Option

While you can vent a single hose unit virtually from everywhere (window, ceiling, door, or chimney), dual hose ACs are trickier to set up. Sure, if you have the perfect window venting opportunity, it's not a problem, but it needs proper access to clean air to function.

Thus, floor or chimney venting might not be an option.

Silent Operation and Higher Than 12 EER Needed

Portable units aren't remarkably silent and efficient. Higher capacity units might reach the 60 dB noise threshold, and the most efficient ones are up to 12 EER. The reason for both negatives is the fact that the unit is entirely indoors. You get extra heat and noise during operation.

If you require more energy efficiency and silence, choosing a wall-mounted AC would be better.

Large Spaces With a Lot of Obstacles

Large BTU dual hose portable air conditioners can cool down spaces of up to 1,500 square feet when mounted in one spot. Still, they aren't designed to work for the whole house simultaneously (only one room at a time).

If your house doesn't have an open plan, the AC can do little to cool the other side of the wall.

Where a Mini-Split or a Central AC Would Be More Efficient 

If you have a huge house and only one little portable AC, it can do next to nothing for the area. There's no doubt how much more efficient central ACs are in this case. Even a multi-split unit could do better, as those can connect several indoor units to one outdoor condenser.

Aspects to Consider Before Buying

There is certainly a difference between cheaper dual hose A/C models and those that are on the nicer side. Check out some of the most important aspects to consider:


Dual hose air conditioners are supposed to cool your home better than a single hose model – so make sure you find one that actually will do so effectively! Well-made models typically are able to get your home cooler than their cheaper counterparts. If you are trying to cool a large space or an open space, this consideration can become particularly important.

Energy Efficiency

One of the best things about dual hose air conditioners is that they will be able to cool your home using significantly less power. When comparing different models, check out the EER (Energy Efficiency Rating) to find one that will use the least amount of energy. Keep your energy bills low by investing in a quality dual hose air conditioner!

Ease of Setup

The one thing that is not great about dual hose air conditioners is that they often are more laborious to set up than simpler, single hose models. Quality units are often able to mitigate this process and make it as painless as possible. Also, higher end units often come with helpful extras, such as additional insulation, to help make the setup process easier and cut down on the likelihood of needing to make a run to the hardware store.

Pros and Cons of Dual-Hose Portable Air Conditioners

Dual-hose portable air conditioners have both their benefits and drawbacks. Here are a few listed below. 


Let’s first go over the benefits 

Whynter 11,000 BTU Air Conditioner

Faster and Efficient Cooling

A dual-hose system is capable of eliminating negative pressure. One of the hose draws air into the unit while the other removes warm air from the room. This makes it 40% faster than single-hose systems and more efficient in cooling the room. 

Access to Windows

A portable AC can be moved around the room or even your house, which is extremely handy for you. A large window AC can sometimes block windows and, therefore, any sunlight in the room. This way, you can move your AC around as you wish.  

Ready to Use

A traditional air conditioner is tedious to install and takes up a lot of time. Portable air conditioners can easily be set up, without any particular tools. They don’t even need to be lifted to place in a vent like a window AC.  


However, they come with their fair share of limitations, which include:

Noise Pollution

Some air conditioners can produce a lot of noise depending on the fan speed and also because all their working parts are in the same room. This can be really annoying. 

Energy Efficiency

Dual-hose air conditioners take more BTUs and use more electricity to run. For this reason, your power consumption is higher. 


Dual hose air conditioners are an excellent, effective option for cooling larger spaces and not using a ton of energy in the process. If you are looking into cooling a commercial space, cooling an entire apartment, or cooling a space with high ceilings, you will likely want to invest your money and effort into a dual hose unit. Take a long hard look at what you want from your air conditioner and make the choice to go with a dual or single hose.

People Also Ask

Here are some of the most common questions related to dual hose models:

Can I Convert a Single Hose AC Unit To Dual?

Many single-hose units come with two intake ports, and you can easily convert them into dual hose ones with some DIY and creativity. If you cannot find the second port, you're probably out of luck.

Other requirements include having a separate evaporator and condenser side airflow and a temperature probe that measures the room temperature.

How Long Can I Expect a Dual Hose Portable AC To Last?

Portable air conditioners can serve you for about ten years. If you examine it periodically, change the filters, and give it proper treatment, it could perform longer.

Is a Dual-Hose Portable Air Conditioner Better?

Dual-hose portable air conditioners are a great option for larger rooms or spaces. This is because they are more efficient and cool a room faster due to their capacity to resolve the negative pressure problem. 

Meanwhile, single-hose portable air conditioners take their time to cool a room. 

Given that, dual-hose portable air conditioners are more costly and take up more power to run. Therefore, it all goes down to your needs. They can be a great option for you given the space you wish to run it in.

Why Do Some Portable Air Conditioners Have Two Hoses?

Some portable air conditioners have two hoses because the two hose system is often able to make them more efficient and effective than single hose systems. One thing to consider with a dual hose air conditioner is that they can sometimes be more laborious to set up, but this additional effort is offset by the multiple benefits that using a dual hose air conditioner can provide (and the reduced maintenance that is often entailed).

Dual Hose Portable Air Conditioner vs. Single Hose – What’s the Difference?

Single hose units are typically cheaper than dual hose units. They are also usually lighter and easier to set up. These units are ideal for smaller spaces as they often lack true power. On the other hand, dual hose units, while more expensive, are far more efficient and require less maintenance. This makes them ideal in terms of cooling larger areas, including commercial spaces.  

How Does a Dual Hose Portable A/C Work?

A dual hose portable A/C takes in air from the outside via one hose, cools it, and pushes it out into the space. It then takes the hot exhaust air and removes it using the other hose, which is more efficient and does not create negative air pressure. As a result, these units are typically better when it comes to conserving energy and reducing your power bill, as well as are more effective when it comes to cooling larger spaces.
