How Does a Portable Air Conditioner Work? 

Portable air conditioners work similarly to refrigerators, the only difference being they cool down the room instead of what’s inside. Air conditioners will send chemicals to the compressor mechanism as a low-pressure gas. They enter as a cold gas and leave compressed together as a high-pressure hot gas.

The condenser then uses metal fins to reduce the temperature which then turns into a liquid. This liquid drips off a cold coil and then is evaporated, collecting heat from the air which more fins help with a process called thermal exchange. So the cold air is replaced with the hot air, and the cycle continues.

Benefits of Investing in a Great Portable Air Conditioner

There are many benefits of using a great quality air conditioner. You should be able to live in comfort without ever having to sweat profusely because you don’t have a quality air conditioner. Some benefits include:

Easy Setup

Being able to set up your portable air conditioning unit should be as simple as plugging it into a socket and letting it do its work. However, this isn’t always the case with cheaper models. A portable air conditioner will also get rid of the hassle of installing a full air conditioning system into your RV.

No Noise

You’ll not be distracted by that horrible buzzing noise that the cheaper models make. In a perfect world, your conditioning unit should make no noise whatsoever. However, many standard and cheap models make so much noise you can’t hear yourself think. Investing in quality will ensure you won’t need to suffer ever again.


A high-grade quality portable air conditioner is going to be suitable to travel around with you. It should be light and easy to carry. However, cheaper models on the market make this a difficult feature to find. Some brands will advertise them as portable air conditioners when they actually weigh too much to carry.

What Makes a Portable AC Great for an RV? 

Air conditioning units for an RV are pretty expensive, which is why it is important to make sure that the one you’re opting for includes all the right attributes. And for you to make the right investment, we have listed the following features which you need to be on a lookout for.  


Depending on how humid your area is, you may have to consider whether you want an evaporative or non-evaporative unit. Most of these portable units are non-evaporative, which means that they take in the air to cool it and exhaust it back out into the room. This helps in making the RV a lot less humid and cool instead. 

Meanwhile, the evaporative units blow the air over icy water and evaporate it while cooling the air in the process. However, this ends up making the air more humid, which makes these units not so suitable for very dry climates. Moreover, these units will require a good amount of either cold water or ice in order to operate.

Room Size

You need to make sure that the size of your RV and your unit is compatible with each other so that the unit offers efficient performance.

You need to opt for a unit that isn’t less powerful, or else it won't be able to cool your RV fully, whereas a unit that is too powerful would be a waste of money. 

BTU Power

BTU, also known as the British Thermal Unit, helps in letting one know which air conditioner unit is more suitable for your RV, based on the size and weather conditions. Now, the average BTU power that a unit features is 13,500 BTU, which is enough to allow the unit to cool down even larger RVs. If your local weather is mostly humid, then you will have to opt for a unit that offers more BTU power.

Honeywell 525-790CFM Portable, Fan & Humidifier with Ice Compartment & Remote, CL30XCWW, White Evaporative Cooler, 525 CFM


  • Ice Compartment
  • Effective for up to 320 sq ft
  • Works Best in Hot/Dry Climates

The method of cooling through water evaporation is used by this AC unit and will be effective in areas of up to 320 sq ft.

The AC unit lists plenty of extra features via the remote control such as the low water alarm that will notify you when it needs to be refilled, the energy saving timer, the adjustable humidification knob that will allow you to set the humidity at the level you like. Other functions such as the ice compartment will gradually introduce colder air to the AC air flow.

Bottom Line

This AC unit works well in dry/humid environments like the American Midwest and will be effective for up to 320 sq ft which is a great distance to cover. The added ice compartment will allow the AC to add cooler air for a longer period steadily.

The remote features like the low water alarm will notify you when the ice needs replaced or the water is low in the tank. The problem with this is that you’ll need to constantly keep refilling the compartments with ice and water which can become expensive or a pain after a while.

Honeywell MN10CESWW Environmental Appliance, Rooms Up To 350-450 Sq. Ft, White


  • Easy Clean
  • Dehumidifier
  • Multiple Features
  • Thermal Protection
  • Works up to 450 sq ft


  • Short Hose

This unit can cool rooms up to 450 sq ft and has decent thermal overload protection for when those hot days take its toll on your AC unit. Overheating is a serious issue, and this protection can literally save lives. The easy clean filter makes your maintenance process far easier.

A window set is included with the product which means you’ll be spending no time trying to find all the different parts to make this AC unit the most effective possible. The hose length for the AC is 4 ft which you can attach to any door or window.

The added bonus of remote control is also something you’ll be able to enjoy with different settings such as three fan speeds and a 24-hour timer. The three in one device will ensure your comfort with the dehumidifier being able to remove up to 66 pints of fluid each day with the option of a continuous drain.

Bottom Line

With cooling a large area such as that, drawing in heat will take it’s toll on the device and will require the best protection, the patented thermal protection will ensure the safety of yourself and the AC if the product ever decides to overheat. The easy clean filter makes your annual maintenance a little bit more smooth.

The different features like the three fan speed and timer can all be controlled via the remote control, this isn’t much of a surprise as mostly all modern AC units have these. The dehumidifier is also included in different models of the same range, being able to consume 66 pints per day of liquid is great but even better when you never have to change it. The only downside that is noticeable is that the hose is quite short at only 4 ft, this seems to be a running theme with this range and should be improved.

LG LP0817WSR 8,000 BTU White Portable Air Conditioner - Rooms up to 200 Sq. Ft


  • LED Screen
  • Remote Control
  • Different Settings
  • Auto-Swing Feature
  • Efficient Dehumidifier


  • Heavy
  • Doesn’t Cover a Great Surface Area

This AC unit will help drastically cool down an area up to 150 sq ft. This device has a sleek and compact design that will allow you to place this anywhere around your RV. The device has an 8,000 BTU and will cool any spot within the RV with the help of an added feature called auto-swing, this feature will ensure any hot spots become cold spots by circulating it far more effectively than other brands.

Bottom Line

This AC unit doubles up as an efficient dehumidifier, with all the standard features plus a few added extras like the auto-swing feature. We’ve not seen anything like the auto-swing on this list yet, this helps combat any hot spots within the RV. The LED screen will display any information such as fan speed, temperature and things like that. The remote control also includes all this information but just makes it easier to play around with.

The dehumidifier can capture around 75 pints of water per day which is then recycled by the evaporation system to help cool the 150 sq ft. The downside of this product is something that it should be great at, and that’s the lack of area it can cover. The 150 sq ft isn’t a lot compared to others on the market that can reach up to 450 sq ft. However, for most RV’s this should never be a problem. Not only that but this product weighs around 50 pounds which is a lot heavier than most other products on the market.

  • LED Display
  • Dehumidifier
  • Easy Clean Filter
  • Multiple Controls
  • Lightweight Design

The different controls that are placed along the LED display will allow you to accurately set how long you want the AC running, sleep mode, or to simply monitor any information like the temperature on one part of the device. The AC also comes with a built-in dehumidifier and fan system that will remove humidity in the air and cool the area with the same liquid that it consumes. The noise created by the system is around 75 db when on the highest setting.

Bottom Line

One thing that you can say about this device is that the lightweight design will prove a helpful ally when trying to find space. This AC unit will fit into any crack in your RV with the help of the four wheels attached and the slim design. The LED screen and multiple different features allow you to monitor and change the temperature around you accurately.

The efficiency of the dehumidifier is also a great asset as it’ll get rid of any hot air while recycling that liquid to further cool the air via the AC. The only downsides to this unit are that it can become fairly loud when operating on the highest setting as well as not being able to cover a large area like other brands.

Bottom Line

An effective AC unit that doubles as a dehumidifier that can consume up to 80.1 pints of water per day with the use of the continuous hose. The AC unit is effective for up to 400 sq ft with 9000 BTU. The multiple settings including the timer, temperature controls, energy saving settings are helpful for any RV owner.

The overnight mode will allow you to sleep comfortably thanks to the low 45 db noise. The only downside to this product is that it will require more maintenance than what a standard AC unit needs which is at least once every year. 

Honeywell MO10CESWB Compact 3-in-1 Portable Air Conditioner w/ Remote Control, Up to 450 Sq. Ft., White/Blue


  • 350 sq ft
  • 192 CFM
  • 10,000 BTU

With an amazing air flow rate of 192 CFM the unit can operate at a noise of 53 db at any time.

The four wheels and light weight of the product make it more than easy to move around.

Bottom Line

According to most users, this unit is a great option for RVs as it is small, portable, and offers efficient performance. It is easy to use and install. It features snap-click connectors that help in ensuring that the hose will stay connected and makes the entire process a lot less frustrating. 

Why it Stands Out to Us

This Koldfront unit is a great option; it offers effective cooling and features a small, compact design, which makes it a perfect option for using in an RV. It can easily cool a room that is 400 square feet in size. It also works as a dehumidifier and can remove up to 2.5 pints of moisture per hour.

Bottom Line

Keeping its size in mind, this particular Koldfront unit offers several features. It is very easy to start up and use. It even comes with a set of instructions to help you in using the unit. It is a suitable option for most RVs; therefore, do consider checking it out. 

Comparison Overview 

Now before you make your final purchase, you must draw up comparisons between the different options available in the market. This helps in ensuring that the decision you’ve taken is the right one. 

With so many options available, picking the right one out can be almost impossible. You want to make sure that you are actually making a wise investment. Most people are often confused even at this point regarding the differences between different air conditioning units that are available for your RV and what sets them apart. So here is our attempt at explaining these differences. 

Dual Hose Portable Air Conditioner vs. Single Hose

The primary difference between dual and single hose portable air conditioners is, as the name suggests, the number of hose these units feature. A dual-hose unit offers an efficient exchange where the air is drawn into one of the hoses where it gets cooled; meanwhile, the second hose vents out the warm air outside of the RV.

BLACK + DECKER 8,000 BTU BPACT08WT Portable Air Conditioner

A single-hose unit not only draws the air but also vents the moisture and the hot air outside. With these, hot air is most likely to leak into the RV, whereas a dual hose system offers efficient performance. Moreover, the dual house systems tend to cost a bit more compared to the single hose ones. 

Portable Air Conditioner vs. Window Unit 

Both portable and window units feature a small size. The main difference is that the former can be moved around the RV, whereas the latter has to be mounted into the windows.

Evaporative Air Cooler vs. Portable Air Conditioner

Unlike a portable unit, evaporative air coolers don’t require an exhaust hose. Moreover, these units can be used outdoors as well. Evaporative air cooler units are suitable for all-year-round climates.

You don't have to vent these units. Moreover, they consume less electricity compared to AC units, and since they use no chemicals to operate, this makes them an eco-friendly choice.

What to Look For in a Portable Air Conditioner

Thanks to the many brands that manufacture portable air conditioners, you’ll realize that finding the best one isn’t an easy task. Thankfully, we’ve compiled a list of features and functions that we believe make a decent portable air conditioner into the best.

Weight and Portability

Like we mentioned earlier, portability, weight and overall design of the portable air conditioner is a huge factor in making this product a great one. Your device should come with a few wheels that allow you to move it around easily.

As well as, handles and a compact design that makes it fit into any environment. The weight is a huge factor; also, you’ll want a conditioner that’s light enough you’ll be fine carrying or wheeling around. Indents are also helpful as this provides extra grip, this design could replace the need for handles.

Remote Control

Having a remote control makes the experience a lot easier. If you’re busy making dinner and you can feel the heat starting to get to you, simply grabbing the remote control and adjusting the fan settings could make a world of difference. If you don’t have a remote, walking over and changing the settings manually via the buttons and dials just isn’t practical in such a modern time. It won’t be the end of the world, but it’s still a great feature to have.

Added Functions

You’ve got your box standard portable air conditioners that provide one service, and that's cooling down the hot air, and that’s great. However, added features like energy saving mode, faster fan speeds or automatic timers can make a huge difference in making your RV experience a comfortable one. If you are willing to pay for the extra abilities, they’re more than worth it.

How to Clean a Portable Air Conditioner

To ensure your portable air conditioner is clean and effective for years to come, you’ll need to conduct some maintenance on it regularly. Cleaning it out can be simple if you follow the correct steps, so we’ve made a step by step guide on how to do exactly that.

  1. You’ll need to find a flat, stable surface to lay your AC down on. Once you’ve sorted that it’s time to remove the cover and place it to the side with any screws you’ve removed also. You don’t want to lose these.

  2. Take a cups worth of bleach and then pour it inside the drain tray so it can start cleaning out any of the sludge. You should leave the bleach reacting for around 10 minutes and then begin spraying down the full air conditioner with a hose.

  3. Wait until the full conditioner has dried out and then to be 100% safe, you’ll want to give it another rub down with a clean cloth. Rinse out the tray that has bleach and sludge inside and then you should add more bleach allowing it to sit for another ten minutes. Once times up, rinse it out and dry it.

  4. Once the device has air dried, screw the housing unit back on and plug it back into the socket to test it out. It’s vital that the full AC has had time to dry, turning it on while still wet could be risky. If you carry out this cleaning process properly, you’ll only need to clean your AC once every year.


By this point in the article, we hope that you’ve learned a few things about what makes a great portable AC unit. If you don’t buy anything from this list, at least you’re now equipped with the information to go ahead and find something that suits your taste.

People Also Ask

An important section for anyone that might feel confused about certain terminology or topics we’ve discussed in the article. We’ve compiled some of the most asked questions and answered them to the best of our ability.

Is a Portable Air Conditioner Quiet?

While all air conditioners make noise, some tend to be quieter compared to others. When it comes to portable air conditioning units, the decibel ratings vary greatly. The average of these units doesn’t need to consistently be 53 decibels. You can find yourself an option that is on the quieter side; however, you will have to check before you make a decision. Remember, the noise produced differs from unit to unit; some will produce more noise compared to others.  

How Much is a Portable Air Conditioner?

Air conditioners can be quite pricey to purchase; therefore, you must opt for a unit that is actually worth the coins. There are some less pricey options available for you to check out as well. You can find some units under $200; however, do understand that most of these low price units are not designed specifically to be used in RVs. 

In fact, these units are your typical units mounted on the windows. They consume more energy, and they produce quite a lot of noise pollution. Units that fall in the $200-$500 price range offer good performance. They consume less power and are mostly suitable for small to medium-sized RVs. 

Units that cost over $600 are among the high-quality units suitable for all types of RVs. They offer top-notch performance along with quiet operation and also feature a high cooling capacity as well. 

Are Portable Air Conditioners Safe in an RV?

Portable air conditioners are mini air conditioners made for your RVs. They feature wheels and handles that allow you to move them around easily. You can easily travel with them, and they are available in different compact designs. 

These units feature either one or two hoses for ventilation. They ventilate the air inside the RV, absorb this air, and cool down the condenser; meanwhile, all the warm air is expelled outside the RV. 

Is a Portable AC Difficult to Use?

Portable air conditioning units operate exactly like a refrigerator. These units, too, feature a refrigerant and the compressor; even the inner workings are similar to that of a refrigerator. 

Moreover, you require the same level of technical expertise to operate both a refrigerator and a portable air conditioner. All you have to do is simply plug in the portable air conditioner, and that’s it.  

What Size Portable Air Conditioner Do I Need?

Before you purchase a portable air conditioning unit, you need to consider where you’re going to keep it and how much space is required. Since it is a portable unit, you can put it anywhere you like. Make sure to measure the space where you’re planning on keeping the unit and purchase one that has the appropriate dimensions. 

How to Vent a Portable Air Conditioner Without a Window

Usually, the easiest way of venting your portable air conditioning unit is through the window; however, it is also possible to do so through the door. 

You can vent your unit through a sliding door. There are kits available for sliding doors through which you can vent your AC outdoors. But the main concern for most people is the length of the hose, which makes it difficult to vent the unit unless it is placed close to the door.

Now, if you cannot keep the door open, you’ll have to use the entry point to vent the unit. You can also vent it through the wall instead, but for that, you will first have to drill a hole into your wall, according to the size of the hose. Pass the hose through it and seal the hole. Another option is that you can vent through the ceiling, or vent through the dryer vent, although most experts are against it. 

How to Drain a Portable Air Conditioner

Generally, portable air conditioning units do not require you to drain them. Many units make use of the condensation exhaust system. This allows them to expel the water vapors that are collected during the cooling process. The moisture collected is then released along with the hot air. 

When the weather is humid, the water that has been collected cannot be exhausted and ends up filling the internal water reservoir instead. This requires you to drain the water tank. To do so, find the drain pan and move your unit so that you can drain it easily. The drain plug is on the back of the unit. Move it along with the rubber stopper and drain the tank. 

How Often Do You Have to Drain a Portable Air Conditioner?

Like we mentioned before, you should be draining this tray out once every year. Every time you clean it, you should be doing this.

Do All Portable Air Conditioners Have to be Vented Out a Window?

You will need to vent most portable air conditioners out into the open. To cool the room effectively, you’ll need to let the hot air outside. You can do this via the window, an open door or make a hole through the wall.

How Much Power Does a Portable Air Conditioner Use?

Different brands will offer AC units that consume more or less power, the amount of energy absorbed depends on the features it provides and how efficient it can run. You’ll always see the power consumption in the information description.

What Size Portable Air Conditioner Do I Need?

The larger the AC unit, the more effective it usually is. However, larger AC units will be far heavier and less portable. You should choose an AC unit depending on the size of your RV, for every 200 sq. ft. you’ll need at least 4000 BTU.
