Who Is Whynter ARC-14S Best For?

The Whynter ARC-14C is the best dual-hose portable air conditioner for anyone seeking powerful and reliable cooling without issues.

Pros
  • Strong cooling capacity for even large rooms
  • Double filters keep indoor air very clean
  • Long exhaust hoses make positioning easy
  • Well-functioning self-drainage keeps your home dry
  • Sleek design
CONS
  • Big and heavy unit
  • So-so energy efficiency
  • Window panel feels flimsy

The temperatures are soaring, and you need efficient cooling — stat! Whynter ARC-14S should be your go-to dual-hose portable air conditioner when you need a unit that does its job and does it well.

This portable AC unit has a powerful 14,000-BTU cooling capacity, putting it in the same class as the Midea and Honeywell units I'll review later on. 

The unit is rated for 500-square-foot spaces but can work well in even larger ones with low ceilings. If you have very high or arched ceilings, though, I would recommend keeping this AC in rooms up to 400 square feet.

The air vents can only be adjusted to blow the cool air upwards, which ensures more even cooling throughout the room. High ceilings can slow the process down quite a bit.

You get the 3-in-1 functionality you'd expect from a modern air conditioner.

This device has AC, fan, and dehumidification modes and a handy timer for setting it to your schedule. I would've liked to see a sleep mode, too, but I didn't end up missing it.

I have to give two thumbs up to maintenance with this dual-hose air conditioner. It has a washable pre-filter AND an activated carbon filter (one of only two units on my list to have one). Both are straightforward to take out and clean or replace.

The filters work very well — I'm asthmatic, so I definitely would've noticed poor air quality.

Drainage is also easy to manage since there’s no drainage to manage. This unit’s self-evaporation feature works very well and uses any condensation to cool the coils.

You might have to drain the condensation tank occasionally in super-humid regions, but generally, it’s not a consideration.

The AC produces about 56 dB of noise, making it one of the loudest I’ve featured. The sound is steady across all modes, though, so you get used to it quickly.

I love the long 5-foot intake and exhaust hoses (a common feature with all Whynter units). They let you position this unit quite freely.

That's a good thing, too, because this is the biggest dual-hose AC on my list and one of the heaviest. It takes up a lot of space, and I'd hesitate to really call it "portable."

In terms of energy efficiency, this Whynter has a SEER rating of 7.69. It’s not the most power-hungry air conditioner out there, but you will notice it on your energy bill.

Overall, though, it’s no wonder this unit is an award winner. It works exactly as advertised, providing efficient and reliable cooling.

Who is Whynter ARC-122DS Best For?

The Whynter ARC-122DS is the best dual-hose portable air conditioner who want good cooling performance at a relatively low price point.

Pros
  • Excellent value for money
  • Strong cooling performance in mid-sized rooms
  • Sturdy and well-designed unit
  • Low energy consumption keeps your bills in check
CONS
  • May draw excessive power with high outdoor temperatures
  • Temperamental remote control

Your budget shouldn’t stop you from living in a nicely cooled space. Whynter ARC-122DS is a relatively affordable dual-hose portable air conditioner that brings plenty of value to the table.

Despite its low price point, this Whynter portable air conditioner sports a respectable BTU rating of 12,000. With a 400-square-foot coverage area, it squarely matches the much pricier Dreo unit in cooling ability.

I wouldn’t try to cool larger spaces with this Whynter, but that’s not a knock on the machine. When used in an appropriately-sized room, this air conditioner can reduce the temperature by 10 degrees in a couple of hours.

Another value-adding factor is the ARC-122DS’ low power consumption, matched only by the Midea AC unit.

With a 12 SEER rating, this portable AC can keep your home cool without impacting your energy bill that much.

In terms of features, this value-packed unit brings you all the advantages of its bigger brother, with AC and fan modes and a 24-hour timer. 

The dehumidifier mode is actually more powerful than on the ARC-14S, making this machine a great choice for regions with high humidity. The only thing it lacks is the activated carbon filter — although that’s available separately.

The ARC-122DS is fairly compact and lightweight. It's not as small as the ultra-portable Honeywell, but at 60 pounds, it's still easy to move and position, thanks to the Whynter family's long 60-inch hoses.

I also have to praise the fairly quiet operation. This unit doesn’t quite match the inverter-equipped Midea or Dreo ACs, but for a traditional compressor, it has a low noise level.

There’s one big warning I must give, though. The owner’s manual states that this air conditioner uses 9 amps of power, but I noticed that it can draw up to 13 amps if outdoor temperatures rise above 90 degrees Fahrenheit.

I strongly recommend that you plug this unit into an at least 15-amp outlet to avoid blowing a fuse or overheating your wiring.

I don’t know what causes the excessive power drain, but you should be aware of it.

The window kit is — like with all Whynter units — pretty flimsy. Fortunately, this unit is otherwise very solidly built. I was surprised by how sturdy it is.

If you’re looking for a portable air conditioner with a dual-hose design and you’re on a budget, I can warmly recommend this machine. 

You get a well-engineered machine and a lot of cooling efficiency for your buck.

Who Is Midea Duo MAP14HS1TBL Best For?

The Midea Duo AC/heater dual-hose model is great for homeowners with large rooms who want the latest high-tech features.

Pros
  • Inverter compressor has high energy efficiency and low noise levels
  • Wi-Fi connectivity makes operating the AC easy
  • Includes a heater unit
  • Lots of cooling power for very large rooms
CONS
  • Expensive
  • Heavy and large unit that must go in front of the window

Do you want it all? Do you want it now? Well, Mr. Mercury, Midea Duo MAP14HS1TBL should satisfy your cooling needs — and heating, for that matter.

Midea has equipped this dual-hose air conditioner with an inverter compressor. With a 14,000 BTU rating, it can freeze you out of a large 500-square-foot room. 

Set up a few fans, and I could see this AC unit keeping even a 1,000-square-foot space livable, if not exactly cold.

As I mentioned, this unit serves double duty as a space heater. I didn’t use the hot air function too much, but it’s efficient — although you need to hook up the supplied continuous drain line.

Although it packs a lot of power, the inverter compressor doesn’t consume much of it.

Midea Duo’s SEER rating of 12.3 matches the Whynter ARC-122DS, tying that machine as the most energy-efficient on my list. 

Although it has no Energy Star rating, it did win the Energy Star 2023 prize for the most efficient portable air conditioner.

The inverter compressor also makes Midea Duo a very quiet air conditioner. Like the Dreo, it has a noise level of only 42 dBA on the lowest setting—a good choice for your bedroom.

The dehumidifier mode on Midea Duo is the most powerful on my list, removing 122 pints of moisture daily.

It also has everything else you’d need, from auto restart to sleep mode (which the Whynter units don’t have).

The remote control has a separate thermostat that helps the unit match the output to the remote’s location.

As a cherry on top of it all, Midea has included built-in Wi-Fi connectivity. You can connect Midea Duo to your smartphone or Alexa to control it from anywhere in your home.

Unlike the Whynter units, which have a separate intake and exhaust hose, Midea has wrapped both into a single enclosure. 

That makes the window panel very heavy and difficult to install — not to mention this is the heaviest unit I’ve reviewed.

The thick hose-in-hose design is also inflexible and forces you to place the AC unit directly in front of the window. 

On the plus side, though, it does add a bit of extra insulation to the hoses.

The unit's black color may divide opinions. I like it (never been a fan of white electronics), but I could see some people thinking it looks like a trash can. Make up your own mind.

Midea Duo is also the most expensive machine on my list at almost $700. Still, if you want a lot of power and all the latest features — including heat — it's well worth the investment.

Who Is Dreo TwinCool DR-HAC001 Best For?

The Dreo TwinCool is the best dual-hose portable AC for quietly cooling medium-sized rooms, like a bedroom.

Pros
  • Quiet and effective cooling for medium-sized spaces
  • Reliable and low-maintenance operation
  • First-grade customer service
CONS
  • Seems to have packaging issues
  • Mediocre energy efficiency

Does the quiet operation of Midea Duo sound nice, but you don't want to spend quite as much? 

Dreo TwinCool DR-HAC001 brings you just as quiet cooling at a slightly lower price point.

Like Midea Duo, Dreo TwinCool boasts an inverter compressor, making it one of the quietest portable air conditioners I've seen. On low, it produces only 42 dBA of noise, and even the highest setting doesn’t get louder than 53 dBA.

In terms of power, this AC unit matches the Whynter ARC-122DS with a 12,000 BTU rating and 400-square-foot coverage area. If you need a dual-hose air conditioner for a big bedroom, Dreo is a great candidate.

I was a bit surprised to see that the TwinCool has an SEER rating of only 8.9. It can't beat the Midea and Whynter ARC-122DS, but it nonetheless has the second-highest energy efficiency on my list.

It’ll bump your energy costs up a bit, but not unbearably much.

Although the TwinCool lacks a heater, it’s otherwise practically identical to Midea Duo in features. 

Frankly, based on my tests and looking at the user manuals, I suspect the internal components come off the same assembly line.

On top of the AC, dehumidifier and fan modes, Dreo offers three fan speeds, a timer, and a sleep mode option. 

Like Midea Duo, the TwinCool has dual thermostats, with one on the machine and one on the remote, allowing it to set the desired temperature according to your location.

There's no Wi-Fi connectivity, but the remote works well enough. I like the Star button (Shortcut in the manual) that lets you save your favorite settings to the remote's memory.

Yet another similarity between the TwinCool and Duo is the hose-in-hose design.

Wrapping the intake and exhaust hose in the same tube does look better and offers some insulation but limits how far you can place the unit from the window.

The Dreo does weigh less than Midea Duo or the big Whynter model, though, which keeps it a bit more portable.

I'm not sure if Dreo has some quality control issues or uses poor packaging, but a lot of people report getting broken units.

That's not too big of a deal, though, since Dreo's customer service is among the best in the business. They don't say much, but you can rely on them to fix any issue your unit might have.

Overall, Dreo TwinCool simply works well. If silence is golden to you, this dual-hose portable air conditioner won’t offend your ears.

Who Is Honeywell HW4CRDAWW0 Best For?

This Honeywell unit is ideal for those looking for a compact and powerful dual-hose portable air conditioner for big spaces.

Pros
  • Produces plenty of cooled air for very large spaces
  • Very compact and portable AC unit
  • Overload protection
  • Very quiet for a traditional compressor unit
  • Example text
CONS
  • Lousy energy efficiency
  • Short hoses

Think you need a big beast of a portable air conditioner for a big room? Think again.

Honeywell HW4CEDAWW0 is the smallest and most portable machine on my list — but it’s also the best for larger rooms.

The Honeywell portable air conditioner is rated for 14,500 BTU, above all other units I’ve reviewed here. It has the chops to cool rooms up to 700 square feet in size.

Yet, with some creative AC and fan placement, I was able to keep spaces almost double that size tolerable.

Despite its power, this Honeywell dual-hose model is only 28 inches tall and weighs less than 60 pounds. It’s a compact and lightweight AC unit, which makes it easy to move.

I wish the exhaust and intake hose were longer than the restrictively short four feet, though.

Although this air conditioner doesn't weigh much, installing it is a hassle because of the short hoses. The window kit is also pretty sub-standard since it doesn't come with any weather stripping.

The Honeywell matches the Whynter AC units in features. It comes with three fan speed settings and can operate in AC, dehumidifier, and fan modes. 

There’s no sleep mode, though, so if you need that, Dreo or Midea might serve you better.

You have a remote operation, although the remote doesn't have a display. On the bright side, Honeywell’s remote is the most responsive out of the ones I tested. It’s basic, but it gets the job done.

The Honeywell is surprisingly quiet for an air conditioner without an inverter compressor. It produces only 51 dBA on the high setting, so I could see myself using it in a bedroom.

This is the only one out of the dual-hose units I reviewed that comes with thermal overload protection. 

If the air conditioner starts drawing excess power (like the Whynter tend to), the protection system stops the condenser, preventing overheating and damage to the unit and electricity lines.[1]

If you start looking for the heater function after reading the user manual, as I did, don't bother — there's no heater.

As far as I know, Honeywell doesn't make dual-hose models with heating, so I'm not sure why that's in the manual.

Yet, my biggest gripe is the very low energy efficiency.

With a SEER of only 2.6, this is the most energy-hungry air conditioner on my list. Be prepared for higher electricity bills with this unit.

Power always comes at a price, though. And if it’s power you’re after, this is the best portable air conditioner for you.

Who Is Cooper & Hunter CH-PDH14AC3 Best For?

Cooper & Hunter’s combo unit is a great option for those who want both heating and cooling for medium-sized rooms.

Pros
  • Performs efficiently as both an air conditioner and heater
  • Good at removing moisture from the air
  • 2-year warranty
  • Good bang for your buck
CONS
  • Drainage problems due to a design oversight
  • Consumes a lot of energy

Cool or warm air — pick your poison. Cooper & Hunter CH-PDH14AC3 can keep you comfortable both in the summer heat and autumn chill.

Like Midea Duo, this Cooper & Hunter model wraps a dual-hose portable air conditioner and a heat pump into one machine. In terms of cooling capacity, it matches its dual-purpose competitor’s 14,000 BTU rating.

Yet it’s heating where this machine really shines. It pumps out a lot of hot air to keep you toasty once the temperatures start falling.

This C&H model offers total climate control for medium-sized rooms.

The AC portion of the unit offers similar functionality as Whynter and Honeywell, with the same fan speed options and 3-in-1 functionality.

The dehumidifier is the second most powerful on my list, removing 91 pints of moisture from the air on a daily basis.

Out of all the air conditioners on my list, this is the only one that comes with refrigerant leak detection — supposedly. I couldn’t figure out how it works, but at least it’s there.

The remote is like the Honeywell's in the sense that it has no display but works fine otherwise.

For some reason, the hoses have different lengths, with one being 5 feet and the other 6 feet. Still, they’re long enough to let you position the unit freely.

Despite having both heating and cooling, the C&H is a fairly compact machine, roughly the same size as Whynter ARC-122DS.

It can fit in slightly smaller nooks as long as you have the muscle to move it — this is a heavy model.

With an SEER rating of 5.93, the energy efficiency is somewhat lackluster. It's all relative, though — compared to running whole-house heating, the C&H can lower your energy bill by a decent bit.

More good news in the cost department: the machine itself is very affordable. That definitely makes the so-so energy efficiency sting less.

The design of the stacked two drain pans is strange. In dehumidification mode, everything works fine — the top pan fills first, and any excess moisture drips to the bottom for circulation as cooling water.

In AC and heater modes, though, the order swaps. The bottom pan fills first, and the water obviously can’t travel upward. Be prepared to rig up a drain line for this unit.

Despite that oddity, Cooper & Hunter has built a good value-packed dual-hose air conditioner/heater combo.

Those looking for heating and cooling capacity should definitely have a look.

Who Is Whynter ARC-110WD Best For?

The Whynter ARC-110WD is a good choice for homeowners looking for a dual-hose portable air conditioner for a small room.

Pros
  • Great for cooling smaller spaces quickly.
  • Great value for money
  • A strong dehumidifier
  • Compact and portable
CONS
  • Low BTUs
  • Excessive current usage
  • Not the most attractive unit.

Whynter makes one more appearance on my list with the ARC-110WD.

With this third machine, the company has manufactured the best dual-hose portable air conditioner for cooling small spaces.

With an 11,000 BTU rating, the ARC-110WD has technically the weakest cooling capacity out of the machines I've reviewed here. However, that's not the whole truth. This AC unit emits icy air and can quickly cool spaces up to 350 square feet.

As I said, ARC-110WD is designed for smaller spaces. Together with the reasonable price tag, it works great in an appropriately sized room.

This unit matches its 14,000-BTU bigger brother in features (three fan speeds, AC, dehumidifier, and fan mode). It actually has the strongest dehumidification out of all Wynther models, sucking out 81 pints of moisture daily.

I appreciate the activated carbon filter, which comes standard, just like on the #1 Whynter machine. It keeps most dust and other particles out to maintain high indoor air quality (as long you remember to keep the filters clean).

The control panel on this machine took me by surprise. At first, I genuinely thought it had the most pathetic controls I’ve ever seen, with only a power and light switch.

Then I realized this dual-hose AC doesn’t have a regular remote. The entire control panel is detachable.

It slots into a cradle on top of the unit, but I guess you could hang it on a wall for an illusion of central air conditioning.

The machine isn’t too big and weighs a reasonable 62 pounds. Combined with Whynter’s 5-foot hoses, this is one of the most portable air conditioners I’ve listed (although not as easily movable as the Honeywell).

The ARC-110WD seems to collect more condensation than the other Wynthers for some reason.

Although the self-evaporation function is fairly effective at repurposing the water, I would recommend coming up with a floor drain solution.

This unit seems to have the same family issue with excessive current drain as the 12,000-BTU Whynter

Make sure to plug it into at least a 15-amp circuit, and be prepared for a bump in your energy bills due to the low 5.87 SEER energy efficiency rating.

Although beauty is in the eye of the beholder, I find this unit’s appearance pretty unattractive.

You shouldn’t judge portable air conditioners by their casing, though. Under that plastic is a capable machine for a smaller room.

How To Find The Right Dual Hose Portable AC For Your Home

Dual-hose portable air conditioners are more efficient than single-hose units—but they’re not all the same.

How can you find the best dual-hose model for your home?

I’ll help you! Here’s my breakdown of the most important factors to consider when shopping for dual-hose portable air conditioners.

BTU Rating Vs Your Room Size

For medium-sized rooms, look for a dual-hose portable air conditioner with a BTU rating of 12,000.

The efficiency of air conditioners is measured in British thermal units (BTU), with the BTU rating directly corresponding to a certain coverage area. 

Portable AC units with 12,000 BTU of cooling capacity can generally cool rooms up to 500 square feet. For larger rooms, aim for a 14,000-BTU unit, like Whynter ARC-14S or Midea Duo.[2]

Note, though, that even the best portable air conditioners — whether dual or single-hose units — lose a bit of cooling power when compared to a central or window AC.

When looking at BTU ratings for portable ACs, I tend to adjust the coverage area down by 50 square feet for more realistic results.

TL;DR: For effective cooling, you must match the BTU rating of the portable AC with the size of the room you wish to use it in.

SEER Rating For Saving Money

Try to find a dual-hose portable AC with at least a SEER 7 rating, but a higher SEER score is always better.

The seasonal energy efficiency ratio (SEER) rating describes how much energy portable AC units consume over a one-year cooling season. 

That sounds technical, but the basic gist of SEER is simple — the higher the SEER rating, the less energy the air conditioner eats, and the more money you save!

There’s no set standard for when a dual-hose air conditioner counts as “energy-efficient,” but I would look for a SEER of 7 or higher to keep your bills in check.

Some portable air conditioner manufacturers claim their units are Energy Star-certified, but don’t fall for that.

ACLAB Note:

Portable ACs are not eligible for an Energy Star rating due to not meeting US DOE requirements.[3]

TL;DR: The higher the SEER the more energy efficient and cost-saving the unit will be to run. However, portable ACs with high SEER rating are often more expensive to buy.

Compressor Type Makes A Difference

I recommend purchasing a unit with an inverter compressor if you want the most quiet and energy-efficient dual-hose portable air conditioner.

Inverter compressors, like those on Midea Duo and Dreo TwinCool, run constantly, unlike traditional compressors, which cycle on and off.

Starting and stopping the compressor consumes more energy and produces noise.

An inverter compressor doesn't cycle, so the noise levels and energy consumption stay in check.

TL;DR: Inverter compressor is recommended.

Installation — Aim For Easy!

Aim for air dual-hose portable air conditioners that come with a full window installation kit that matches your window opening.

Although a portable air conditioner is practically always easier to install than a window AC, it can get tricky. 

A complete installation kit, with a window panel and weather stripping, makes the job simple and straightforward. I’d also keep an eye out for units that come with a floor drain hose.

I recommend measuring your window carefully before buying a portable AC and comparing it to the maximum dimensions of the window panel. 

With some units, you may have to cut the panel to fit small windows.

TL;DR: Look for a unit with easy installation especially if you plan to move it around.

Noise Levels — The Lower The DBA, The Better

I always look for portable air conditioners with a maximum noise level of 55 dBa.

Portable air conditioners tend to be louder than most other models, but you shouldn't have to put up with a blaring machine. 

My personal breaking point is at 55 dBA, but some people can put up with noise levels up to 60 dBA.

That's comparable to a regular conversation.[4]

If you want a really quiet unit, look for something with an inverter compressor, like Midea Duo or Dreo TwinCool.

These units make less noise than most other portable ACs and can provide soothing white noise even in a small bedroom.

TL;DR: Portable ACs have their compressors built-into them. Hence, they can get loud. Look for a unit with lowest dB rating if you are susceptible to noise disturbance.

Price — Don’t Spend Too Much

Decide on your budget before you start shopping for dual-hose portable air conditioners to make finding the right machine easier.

Dual-hose models tend to be more expensive than single-hose portable ACs — the units on my list range from around $400 to $700. 

I can’t tell you how much to spend, but determining your budget ahead of shopping helps you avoid wasting time with units you can’t afford.

TL;DR: Dual hose ACs are more expensive compared to single hose portable ACs.

Separate Hoses Vs Hose-In-Hose

Choose a dual-hose unit with separate hoses or a hose-in-hose design based on whether you want flexible positioning or better insulation.

The exhaust and intake hose of dual-hose units can be separate, or they may be contained in a single enclosure, called hose-in-hose.

Separate hoses are more flexible but often thin and may allow heat energy to radiate back into your home. 

A hose-in-hose structure is often better insulated, but it is also stiffer and restricts where you can place the air conditioner.

TL;DR: Separate hoses make it easier to install the unit, but at the cost of insulation.

Other Features To Look For

There are other smaller but still important details to keep an eye on when browsing dual-hose AC units.

Consider these things to find a machine with the best features for you:

Portability If You Plan to Move It Alot

If you plan to move the machine a lot, look for portable AC units that are small and lightweight.

Ideally, they should also have caster wheels so you can easily roll the unit along the floor.

How Easy It is to Maintain

Check how easy it is to remove the filters and gain access to the internal components so you can keep your dual-hose unit clean.

With dual-hose ACs, most models recycle condensation water to cool the internal coils, so extensive drainage is rarely needed.
The Length of the Warranty

The longer the warranty period on your AC, the better.

All dual-hose units on my list offer at least a year of warranty, but some — like Cooper & Hunter — give even longer warranties.

Extra Features
  • Timer:
    A good 24-hour timer lets you set your portable AC to run automatically when you need it the most. This can save you a good bit of money — there’s no point in cooling your house if nobody’s home.
  • Filter:
    If you're sensitive to airborne contaminants (like I am), choose a unit with a standard activated carbon filter, like my #1 Whynter ARC-14S portable air conditioner. Additionally, aim for portable AC units that have washable filters to save some money on replacement filters.
  • Thermostat:
    An accurate thermostat helps your AC maintain a comfortable air temperature in your home. All portable units on my left have reasonably accurate thermostats, so any will work well.
  • Remote Control:
    A good remote controller with a display makes operating your portable AC unit much easier. Every portable AC unit on my list has a remote, but some — like Honeywell and Cooper & Hunter — lack displays, limiting their usability.
  • Wi-Fi Connectivity:
    A smart portable air conditioner with Wi-Fi capability — such as Midea Duo — can connect to a smartphone or a voice control unit, like Alexa. This can make controlling the appliance very simple.

TL;DR: Separate hoses make it easier to install the unit, but at the cost of insulation.


How Do Dual-Hose Portable AC Units Work?

Dual-hose portable air conditioners draw air from outside your home instead of from the inside.

This makes them more efficient and powerful than single-hose units.

A single-hose model pulls in hot air from inside the room it’s placed in. This generates a negative pressure inside your home, causing warm outside air to seep in through cracks and gaps to replace the removed air. 

The encroaching warm air can re-heat your home and force the single-hose model to work harder.

Dual-hose units, on the other hand, use separate exhaust and intake hoses to expel and draw in air from outside your home. 

The dual-hose machine cools the air it pulls in and emits it into your home. 

The cooling process generates heat energy that the machine spews back out through the exhaust hose.

This method allows dual-hose units to cool your home much faster while eliminating the negative air pressure problem.

The only downside is that these machines generally cost more than single-hose units.

TL;DR: Dual hose ACs draw in air from outside instead of from the room. As such, they are more efficient at cooling as compared to single-hose portable ACs.

FAQs

What Are The Benefits of Dual-Hose Portable ACs Over Single-Hose Models?

Dual-hose portable air conditioners cool indoor air faster and more efficiently than single-hose models. They are also generally better at filtering impurities out of the air.

Is A Dual-Hose Portable Air Conditioner Better?

A dual-hose portable air conditioner is more efficient in terms of cooling than a single-hose one. However, they also tend to be more expensive and may be louder than comparable single-hose units.

Do You Have to Drain a Dual-Hose Portable Air Conditioner?

You generally don’t have to drain most dual-hose air conditioners as they recycle condensation water to cool their components.

If you live in a region with a very high humidity level, your portable AC may need some help from a drain line.

Can you Convert Single-Hose AC to Dual-Hose Configuration?

You may be able to convert a single-hose AC model to a dual-hose configuration by building a makeshift hose adapter over the intake vent.

Yet, it can be difficult and is far from a perfect solution, so for most users, buying a new dual-hose AC is often the best solution.
