Best Dual Hose Portable Air Conditioner Reviews (Top 10 List)

1. Whynter ARC-110WD Dual Hose Portable Air Conditioner

If you want the best dual hose portable air conditioner with good cooling coverage at an affordable price, then this Whynter ARC-110WD unit is a top choice.

This dual hose portable AC unit has a cooling capacity of 11,000 BTU (ASHRAE) / 6,390 BTU (SACC), which is powerful enough to bring cool air to a room measuring up to 350 square feet. 

It also features CFC-free refrigerant and lead-free RoHS compliant components, which make it one of the most environmentally-friendly dual hose portable air conditioners available. 

There are four operational modes to choose from so you can get the exact cooling comfort you need: air conditioning, fan only with 4 speeds, dehumidifier, and automatic mode. 

It has an adjustable thermostat with a range of 61-89º F, giving you more control to find that perfect temperature. Meanwhile, the dehumidifier function is powerful enough to remove up to 81 pints per day. 

Switching through modes is as easy as pressing the buttons located on top of the unit. Or, if you’re after even more convenience, you can use the included remote control. Both methods can also be used to set the 24-hour programmable timer.

The Whynter ARC-110WD has a self-evaporative system that exhausts condensation under average ambient conditions. That means you won’t have to empty a water collection bucket or connect a drain hose.

For extremely humid conditions, a direct drain option is available for continuous operation without excess condensation accumulating. But most people don’t need to use it.

A carbon air filter is included in addition to the standard pre-filter. The carbon air filter helps to trap any airborne dust particles, allergens, and odor molecules for better air quality.

The built-in wheels allow you to move this portable air conditioner with dual hose between rooms, and it comes with an upgraded window kit with a 47-inch extendable exhaust and intake hoses that make installation quick and simple.

The auto-restart function means that this dual hose portable air conditioner will begin running again following a power outage. It also features an LCDI (Leakage-Current Detection and Interruption) plug. This automatically detects if the power cord is internally damaged or frayed, resulting in a reduced risk of fire for your safety.

As for noise, it outputs around 55 dBA, which is quite standard for these types of cooling units.

Dual Hose Portable Air Conditioner Buying Guide

What is a Dual Hose Portable Air Conditioner?

A dual hose portable air conditioner is a cooling unit that has two hoses on the back of the appliance. One of the exhaust hoses functions as an air supply (or intake hose), and the other is an exhaust hose.

The air brought into the room from the intake hose is cooled within the AC unit before being pumped back out into the room. Meanwhile, the second exhaust hose vents the air that is used to cool the internal compressor and condenser coils of the unit, and pumps it outdoors. 

Unlike most standard air conditioning units, dual hose portable air conditioners are easy to set up and don’t require any permanent installation. You simply raise a window about six inches, slide the window kit into place, connect the dual hoses from the back of the unit, and turn it on.

Dual Hose vs Single Hose Portable AC Unit

The key difference between a dual hose and a single hose portable AC unit is that a dual hose air conditioner uses two hoses for the cooling process while a single hose system only uses one hose.

In a single hose portable air conditioner, hot room air is drawn into the system, flows across the internal coils, is cooled, and then pumped back into the room. Some of this air is also used to cool down the internal components of the AC unit. And once this is done, the air is then exhausted outdoors through the single exhaust hose. 

In a dual hose portable air conditioner, the first hose (i.e. intake hose) draws outdoor air into the AC unit to cool down the internal components. The second hose (i.e. exhaust hose) takes the air that has been used to cool the AC unit down and sends it back outside.

The design of a dual hose portable air conditioner means that the unit is much more efficient at cooling down a large room in a faster amount of time. These units don’t have to work as hard as single hose portable air conditioners as there isn’t just one hose sharing the in-and-out workload.

Features to Look for in a Dual Hose Portable Air Conditioner

Best Dual Hose Portable Air Conditioenr

To get the best dual hose portable air conditioner for your home, there are some important things you need to consider.

Below, we’ll take a look at some key points to bear in mind when you start shopping. 

Paying extra attention to these types of functions will help steer you in the right direction and, ultimately, save you time and money on your purchase.

Now you don’t have to get every one of these features to have a good dual hose AC unit. As long as it can cool efficiently, then you’re set. So just pick the elements that would make your life and user experience more comfortable.

Dehumidifier Mode

A dehumidifier mode is a good feature to have because the temperature isn’t always to blame when you’re feeling hot in your home. Sometimes it’s the level of humidity in the air that’s making it feel so warm. 

A dual hose AC unit with a dehumidifier mode will remove the moisture from the air and leave the room feeling cooler and the air less sticky.

You can also run this mode without having to run the air conditioning compressor. This can often make a room feel cooler while saving on energy.

Some portable dual hose ACs have larger dehumidifier capacities and can pull up to 100 pints of water out of the air each day. 

If the portable air conditioner has a dehumidifier, then it will also have a self-evaporative function, a water collection tank, and/or a drain spout.

The self-evaporation function is the best type because it exhausts the collected moisture out the exhaust hose outdoors. With a water collection tank, you’ll have to empty it as it gets filled. And the drain spout eliminates that hassle by letting you connect a hose to the unit to let the water slowly trickle out and into a floor drain.

Heat Mode

As with anything you spend your hard-earned money on, it’s nice to be able to get as much use out of a dual hose portable air conditioner as possible. 

Some products have a heat mode in addition to cooling that allow you to warm up a room during the winter months. And, when the summer months come round again, you can use the same unit to cool your room down.

So if you want a year-round appliance for both heating and cooling, then make sure to buy a dual hose portable air conditioner that can also heat a room.

Sleep Mode

A dual hose portable AC unit with a sleep mode is a great thing to consider if you’re going to use the appliance in your bedroom.

This mode will automatically adjust the settings of the air conditioner so that it operates at a quieter noise level so that it won’t disturb you while you’re sleeping.

Smart Wi-Fi Control

Not all dual hose portable air conditioners have smart Wi-Fi controls, but if you like the idea of being able to power it on when you’re on your way home using your smartphone or set schedules for the AC unit to run, it’s a great feature to look out for. 

Some dual hose AC units can be paired with a smart assistant, such as Alexa or Google Home. This gives you the power to switch through the various settings by only using your voice. 

Remote

A remote control is often a must-have device for adjusting the temperature settings and selecting different modes from a distance. 

Timer

A timer allows you to program the air conditioner to switch itself off after a certain period of time. This will usually be across a 24-hour period, and it’s particularly useful if you’re trying to conserve energy as you won’t have to worry about remembering to manually turn the unit off.

A timer is also a useful sleep feature, as you’ll be able to fall asleep with the air conditioner on but rest assured that it will turn itself off after a set number of hours.

Noise Level (dBA)

It’s also worth giving some thought to the noise level that your dual hose air conditioner operates with. 

Traditionally, air conditioners are thought to be extremely noisy. But, thanks to advances in technology, some ACs now run at the same noise level as a normal conversation.

The noise level of dual hose portable AC units range between 50-56 dBA.

Getting the Right Dual Hose Portable AC Size

One of the most important things you need to consider when looking for a dual hose portable air conditioner is its size. 

This doesn’t necessarily mean its physical size, although it’s always worth looking at how much space it will take up. By size, we mean the number of BTUs it has. 

The easiest way to work out what size portable air conditioner you need is to measure the square footage of the room you want to use it in. This can be figured out by multiplying the length by width, such as 15’ x 20’ = 300 square feet.

Once you’ve got that number, you can match it against the number of BTUs that are appropriate for your space. 

To make things easy for you, we’ve put together this chart that tells you how many BTUs you’ll need for a specific amount of space (i.e. square footage). 

Room Area To Be CooledBTU Capacity Needed
up to 250 sq. ft.6,000 BTU
up to 350 sq. ft.8,000 BTU
350 to 400 sq. ft.9,000 BTU
400 to 450 sq. ft.10,000 BTU
450 to 550 sq. ft.12,000 BTU
550 to 700 sq. ft.14,000 BTU

It is worth noting that this chart is just a general guide. Some dual hose portable AC units may cool more or less than the room size listed above based on the quality of their components. 

With this in mind, make sure you check the technical specifications to get the exact measurement.

BTU Ratings: ASHRAE vs DOE Ratings

You may notice that all of the dual hose portable air conditioners we’ve reviewed above have BTUs listed in both ASHRAE and DOE SACC ratings. 

But what does this mean? 

Below, we’ll try to explain this as simply as possible. 

In 2016, the DOE (Department of Energy) passed a rule that ensured manufacturers of portable stand-up air conditioners built models that would use 20% less energy than the least efficient models that were currently available.

While this new rule is yet to come into full effect, many air conditioner manufacturers have already adopted the regulation and are creating AC units that are much more energy efficient. 

So how do ASHRAE and DOE SACC ratings apply to this?

ASHRAE BTUs reflect older testing standards. This comes from a time when portable ACs were tested to the same degree as window AC units. 

The ASHRAE BTU rating simply refers to the amount of energy required to remove the heat from a space, rather than the actual efficiency of the unit as felt by the person using it. 

DOE BTU ratings are the new standard for testing portable and stand-up air conditioners. This stems from the fact that so many inefficiencies were found in portable air conditioners using the old ASHRAE BTU measurement.

A DOE rating will be abbreviated as SACC (Seasonally Adjusted Cooling Capacity), and it’s simply more accurate than the ASHRAE rating when looking at the efficiency of the air conditioner in terms of what the user experiences.

The SACC is usually about 50-60% lower than the ASHRAE rating.

Here are some examples of the comparisons between ASHRAE and SACC ratings for portable air conditioners:

  • 14,000 ASHRAE = 7,500 SACC
  • 12,000 ASHRAE = 6,500 SACC
  • 10,000 ASHRAE = 6,000 SACC
  • 8,000 ASHRAE = 4,500 SACC
  • 6,000 ASHRAE = 3,000 SACC

So when you’re looking for a dual-hose portable air conditioner, it’s extremely important that you pay attention to the DOE BTU rating. This will give you a better representation of how user-experience efficient the air conditioner will be in a certain room size.

Common Questions About Dual Hose Portable Air Conditioners

Best dual hose portable AC unit

Is a dual hose portable air conditioner better?

When you compare a dual hose portable air conditioner to a single hose air conditioner, there is an undeniable difference in performance. The most important of these is that they are able to cool a room down in a faster amount of time without having to use as much energy. 

Do you have to use the hose on a portable air conditioner?

You do have to use the hose on a portable air conditioner. There is no way to run a portable air conditioner without an exhaust hose as the hot air will simply be vented back into the room.

Can you use a dryer hose for a portable AC?

You can use a dryer hose for a portable AC unit if it will fit. A dryer hose is typically 4” in diameter while portable AC hoses are 5” in diameter. If your portable AC unit has a 4” hose, then the dryer hose will fit easily on the back of the unit. If not, you’ll need to modify the connection point to the dual hose portable air conditioner.

Keep in mind that you should only use a dryer hose as a temporary solution for a broken dual exhaust hose. Each manufacturer will use a specific type of hose for their product that meets the demands of the technology.

By using a smaller size hose or unapproved hose, like a dryer hose, the unit can void its warranty and/or become unsafe to operate due to heat buildup.

Can you extend the hose of a portable air conditioner?

You cannot extend the hose of a portable air conditioner. The exhaust hose that came with your portable air conditioner has been specifically designed for use with that particular unit. Extending the hose can cause the unit to operate inefficiently and will reduce the cooling effectiveness of your portable air conditioner.

What happens if you don’t vent a portable air conditioner?

If you don’t vent your portable air conditioner, then it will not cool your room. The portable AC unit will blow the heat right back into your room. Essentially, not venting a portable AC unit turns it into a dehumidifier.

Can a portable AC cool multiple rooms?

A portable AC can cool multiple rooms if those rooms are connected. Also, the portable AC unit has to be powerful enough to cover the total square footage of multiple rooms. However, this will not be as effective and efficient compared to separate AC units for individual rooms.

How many years does a portable air conditioner last?

A portable air conditioner lasts about 10 years. If you maintain the portable AC unit well, you can usually get another 5 years or so of service life. You can double the lifetime of the portable AC by using it less often or by reducing the cooling load.

How to Install a Dual Hose Portable Air Conditioner

As with all air conditioning systems, a dual hose portable air conditioner needs to be installed properly if you want to make sure it runs efficiently. 

Below, we’ll give you a step-by-step guide on how to properly install a dual hose portable air conditioner that’s based on general manufacturer instructions.

  1. Find the best location: Your dual hose portable air conditioner needs to be placed near a window and near an electrical outlet. Once you’ve found a spot with both of these things within reach of the unit, make sure that the air conditioner doesn’t present as a trip hazard. You also need to make sure the airflow isn’t going to be obstructed by any furniture. 
  1. Put the window kit into the window: Open the window sash about 6 inches and place the included window kit into the space. Then slide the moveable portion of the window kit until it spans the length of the window frame. Finally, close the window sash until it rests on top of the window kit to prevent it from falling out of the window. 
  1. Connect the exhaust hoses: Connect each exhaust hose to the back of the unit. Most units require you to turn the hose in a clockwise position until so it can screw into the back panel.
  1. Attach the exhaust hoses to the window kit: The window kit should come with an adapter piece that connects between the exhaust hose and the window kit. One side of this adapter usually twists onto the hose in the same manner as you installed the hose to the back of the portable AC unit. The other side snaps into the opening of the window kit.
  2. Plug in the air conditioner: Connect the dual hose portable air conditioner’s plug to the electrical outlet. Switch the unit on, select your preferred mode and temperature, and enjoy the cool air.
