What Should I Look For When Buying The Best Portable AC Unit For RV?

Are you in a dilemma of the best portable AC unit for RV to purchase? Relax! Here are full details on all the features that will help you get a high functionality air conditioner.

No more stories! Let get to the crux of the matter.

  • Cooling capacity

Simply put, the cooling capacity of an AC is the measure of its ability to extract the excess heat in the air.

The cooling capacity is measured in British thermal unit, which is abbreviated as BTU per hour.  Consequently, the higher the BTU, the more powerful is the AC.

Further, the cooling capacity limits the amount of space that the AC can cool. For instance, an AC with a cooling capacity of 12,000BTU is recommendable for a room of up to 550 sq. ft.

  • Functionality

Most of the current air conditioners are multipurpose.

Some of their standard functionalities are cooling, dehumidifying, or fan functionality. Typically a 3-in-1 unit has cooling, fan, and dehumidifying functionality, while a 4-in-1 goes a step further to include the heating functionality.

What is my point?

This is it; you should identify your current problem, for instance, if it is excess moisture or high temperatures and specifically look for a unit that can offer that. Otherwise, it wouldn’t be a shock if you purchase an item that does not meet your expectations.

  • Size

Do you have a small or large space to set up the unit? You need to get that clear before setting your foot to purchase the air conditioner.

If you have a small space, then the unit should have a small base area to take less space.

Still, if you will be regularly changing its location, you need to check on its portability. A portable AC unit usually has a lightweight design.


  • Mode of operation

With the current advancements, most of the air conditioners have a silent mode of operations.  Nonetheless, you should confirm it for yourself.

But why is it necessary to check on the noise level of an air conditioner?

The big reason is that the noise may affect your activities, especially for indoor use. Will you be able to cope with the noisy AC while sleeping? But even before that, how will you concentrate in a loud house or even when riding in the RV?

If you are purchasing for outdoor use, you are likely to think that you got your way out?

But check this; most of the local authorities have noisy restrictions. Besides, while purchasing AC for RV, most camping sites have loud limits, mostly at night.

Without any doubt, a relatively silent air conditioner is highly recommendable.

The outdoor units have a noise range between 19db to 53db,while outdoor units have a noise rating ranging from 42db to 69db.

  • Sleep mode

Ideally, an AC with a sleep mode is highly recommendable

Before that, what does ‘sleep mode’ refer to?

An air conditioner with sleep mode implies that it can regulate the airflow at night by automatically increasing the air temperature by up to 1 degree per hour, depending on its settings.

As a result, such an air conditioner ensures that you get comfy and maximum sleep. But that is not all.

To add on, an air conditioner operating in sleep mode consumes less power and energy, thus making it an energy-saving item.

  • Fan speed

Before I jump right ahead, get this; the air conditioner fan is the main component that affects the room’s cooling or heating.

Simply put, it is the heart of every air conditioner. Resultantly, failing to inquire more about it brings in many regrets

Let’s get to the main deal now.

The fans have different speeds. Typically, there are low, medium, and auto speeds.  The high speed is recommendable for a very humid and hot area. However, you should note that not every air conditioner will give all the three settings; some may have two or even one.

What Is A Portable AC?

A portable AC is a small-sized conditioner which has a compact design for mobility.  They are standardly designed to sit on the floor or have a temporal setup kit such that the installations and removal are so simple.

Portable AC’s are commonly used in offices, bedrooms, living rooms, and vehicles. In simpler terms, their design is for situations where a central  AC unit is not convenient.

How Does This Portable AC Work?

Basically, the portable AC cool the room by taking in the warm air and moisture and exhausting it through the window kit. Resultantly, it has to be vented outside to provide a place to deposit the hot air.

It has a refrigerant that moves in the tubes while absorbing the excess heat of the indoor air. After absorbing the heat, the refrigerant condenses to a liquid and travels to the outdoor unit.

While on the outdoor unit, the excess heat is removed from the refrigerant, and it changes its state again to gas and travels back to the inner unit.

Types Of Portable Air Conditioner Units For RV

There are several types of portable air conditioners. They include;

  • Window air conditioner

This type of AC is a single unit air conditioner usually mounted on the walls or windows. Actually, it is known to be the simplest form of an air conditioner.

It has two fan motors, which are incorporated such that one is facing the evaporator side while the other one faces the condenser side. When installing it, the evaporator side should face the room while the condenser side faces the outdoor side.

It has a drain pan that contains the water from the cooling coil, which is later drained by the use of gravity.

  • Vented-air conditioner

A vented AC is an air conditioner that uses ducts. Consequently, there have been many claims that usinga duct system leads to heat loss, which decreases the heating efficiency of the air conditioner.

The ductless air conditioners are gradually replacing this type of air conditioner.

  • Vent-free air conditioner

Vent-free air conditioner, also known as ductless air conditioning, is remarkably versatile. Its construction makes it possible to install it almost everywhere for cooling purposes.

Because of the bare fact that it does not use ducts, its operations are relatively silent. Consequently, unlike other types of air conditioners, you do not have to bear noise pollution.

Besides, due to its ductless nature, it is considered to be energy efficient. As air flows through the ducts, it is prone to losing some heat, thus lowering its temperature, which results in power loss.

What is the catch? Using a vent free air conditioner guarantees an optimally working device.


  • Split air conditioners

Addedly, there is a split air conditioner that has two central units. That is the compressor on the outside and an air outlet on the inside part.

They use a set of pipes that connect the outdoor to the inner unit. For cooling purposes, this type of air conditioners uses a refrigerant in the copper pipes to cool or generate heat

  • Self-evaporative air conditioner

This type of air conditioner was invented to do away with the need toempty the bucket manually. Consequently, it has bucket-less design.

It uses a self-evaporative mechanism such that the water is not stored but evaporates.

Dual Hose Portable Air Conditioner Vs. Single Hose

The hose is used to access the cooled air. Air conditioners can have a single hose or dual hose construction.

To get the main difference between the two, let’s first understand the working of the hose.

The hose is functioned to remove the warm air in the room to the outside, thus creating a pressure imbalance between the room and the surrounding.

Consequently, to keep the air pressure at balance, the cold air from the outside environment gets into the room through the windows or other openings. Correspondingly, cooling the room.

As the name suggests, a single hose design has only one hose. Thus it has to work more intensively than a dual hose design to cool the room.

In contrast, the dual hose design has two functioning hoses—consequently, they cool the room much faster. Further, due to reduced work that each hose is handling, its filters’ lifespan is immensely enhanced.

Dual hose design AC is recommendable for large spaces due to its quick and efficient way of cooling.

Portable Air Conditioner Vs. Window Unit

A portable air conditioner is a conditioner that has a compact design and an exhaust that connects to the window. By compact design, it implies that you can easily carry it along.

Why would you choose a portable air conditioner?

First is the mere fact that their movements are easy. Also, the installation process is very straightforward. And lastly, due to the compact design, it will cover a small space

And as fate has it, portable air conditioners have its demerits too. To begin, you will need extra space for the vent on the window.

Also, despite all the manufacturers’ efforts to provide silent operations, the humming sound of the AC is likely to be audible.

On the other hand, a window unit is a type of air conditioner with a single box design. They are a good alternative when looking for a permanent central cooling system.

The main advantage of a window unit is that it does not use a vent, and most of its noise is directed to the outside. However, most people dislike the fact that they take ages to install and likely block the window.

Which is the best for RV? Portable or window unit AC

Personally, I would recommend a portable AC for RV.  Why?

Generally, it is due to its mobility. They are quite simple to install as well as remove. Even further, portable AV has quite simplified operations.

Evaporative Air Cooler Vs. Portable Air Conditioner

A portable air conditioner is a mobile system that works to remove excess heat and moisture from the air using a refrigerant.

The refrigerant, also known as a coolant, is a special fluid that removes the excess heat or moisture from the air. This fluid moves through the copper coils and cooling tubes, which connect the outside unit to the internal units.

The fluid absorbs the heat from the indoor air and condenses to a liquid. It travels back to the outdoor unit, disperses the extra warmth, and evaporates back to gas.

An evaporative cooler, also known as swamp or desert cooler, is a device that cools the air by use of water evaporation.

Unlike the air conditioner, an evaporative air conditioner cools the air by vapor compression by a water-soaked medium.

When the air gets into the medium, it comes into contact with the cold water, which absorbs the extra heat in the air molecules—resultantly cooling the air.

When should you consider an evaporative cooler?

Evaporative air coolers are recommendable outdoor due to the need for plenty of fresh air. Also, they are recommendable when you are not ready to incur a high maintenance budget. That is because they are relatively cheap to maintain.

Which is the best for RV users?

Portable air conditioners are recommendable for RV users over evaporative coolers.

How To Calculate The AC Size Or BTU

Air conditioners have different sizes, which determine their cooling capacity. Typically, an AC size will not refer to its dimensions, but rather the amount of space it can cool.

The cooling capacity is measured in British thermal units abbreviated as BTU.

But how will you know the right size or BTU efficient for your RV or house?  That will need you to perform a mathematical calculation.

Don’t freak out! I am here to guide you on how to perform the calculations. And if you are not ready for some calculations, I will offer a table to guide you. Let’s dive in

Before jumping right ahead, the calculations are dependent on some factors.Hence, some adjustments are recommendable on certain conditions such as;

  • For a heavily shaded room, increase the capacity by 10%
  • In scorching areas, increase the capacity by 10%
  • A room with more than two regular occupants add 600BTU for each extra person.
  • For kitchen use, increase the BTU by 4,000btus

To the calculation;

Step1; get the room or RV measurement

To get the room area, measure its length and width. After, multiply the two measurements.

Note; the measurements should be in feet units. If you are using any other units such as meters, you will have to convert them.

Step 2; get the BTU

The BTU of the air conditioner should be minimally 25 times the room area.

Thus, multiply the area of your room from the first step with 25.

For example

Assume that you have a room whose length is 12 feet and the width 10 feet.

Hence the area will be;

12×10= 120sq.ft

The BTU for the air conditioner;

120×25= 3000BTU

Cooling Capacity Chart

Size of Area Capacity Needed
100 to 150 square feet 5,000 BTUs per hour
150 to 250 square feet 6,000 BTUs per hour
250 to 300 square feet 7,000 BTUs per hour
300 to 350 square feet 8,000 BTUs per hour
350 to 400 square feet 9,000 BTUs per hour
400 to 450 square feet 10,000 BTUs per hour
450 to 550 square feet 12,000 BTUs per hour
550 to 700 square feet 14,000 BTUs per hour
700 to 1,000 square feet 18,000 BTUs per hour
1,000 to 12,00 square feet 21,000 BTUs per hour
12,00 to 14,00 square feet 23,000 BTUs per hour
14,00 to 1,500 square feet 24,000 BTUs per hour
15,00 to 2,000 square feet 30,000 BTUs per hour
2,000 to 2,500 square feet 34,000 BTUs per hour

Which Are The Factors Considered To Calculate The Size Of A Portable AC?

Before I jump right ahead to the factors to consider, I need to clear up something.

By now, you are aware that a lower BTU isn’t recommendable for obvious reasons of inefficiency. But the same applies to a higher BTU. You may think that getting a higher Btu will quicken the process but not at all.

Here is the explanation.

A too high BTU makes the unit cool faster and causes a continuous cycle to maintain the temperature that you have set. The repetitive cycling leads to inefficient moisture removal as expected.

You can now guess the results, a humid environment perfect breeding of bacteria and mold, and a significantly stretched energy bill.

To the critical matter now;

Considering that no room has the same structures, the cooling capacity for every room varies. Some of the things to consider are;

  • Number of occupants

In a room with more than two regular occupants, the AC’s standard cooling capacity should be increased by 600BTU.

For the RV, check on its capacity and multiply by 600 BTU. For instance, if it is a 14-seater, there are ten extra persons. Thus you should increase the cooling capacity with 6000BTU.

  • Room shading

In a place with heavy shading such that most of the sunlight is blocked, the cooling capacity should be increased by 10%.

  • Application

This factor is to be considered when purchasing an air conditioner for home use.  When setting it on kitchens with quite heavy appliances, or any other extremely warm room such as a server room, the BTU should be increased by 4,000BTU.

  • Natural climatic condition

Keeping all other factors constant, how would you describe the area’s natural climatic conditions, too hot or cold?  For extremely sunny areas, then the BTU should be increased by 10%

  • The ceiling

How far is the ceiling or the upper part of the RV located? If it is beyond 8 feet, then increase the BTU by 10 percent for each foot.

For example, if the space left is 10 feet, there are two more feet. Hence you should increase the BTU by 20%

What Makes A Portable AC Great For RV?

A portable AC is an excellent option for maintaining a cozy environment in a recreational vehicle. In fact, most of these devices will cool the air and remove excess moisture, which is the leading cause of mold and mildew.

Nonetheless, there are things that you should regard to ensure that you get an excellent AC for an RV. The factors include;

  • AC type: There are several AC types, including vented AC, evaporative, window unit, and portable AC. Most RV-ers opt for a portable ventless AC. That is to avoid the need for regularly draining the tank.
  • Size- most portable ACs have a mini-sized to ensure they take less space in your vehicle
  • Cooling capacity- the cooling capacity of an AC is measured in BTU. You should ensure that the cooling capacity of the AC will cool all the parts of the RV effectively
  • Installations- portable AC for RV should have straightforward and fast installations and removal.

Benefits Of Investing In A Portable Air Conditioner

Portable air conditioners are indispensable devices for every RVer.  Or are you ready to let the sunny day ruin your trip? I guess not.

Portable AC ensures that you enjoy a favorable condition while traveling to your destination. Even better, if you are going camping, you can remove it and use it at the camping site.

But wait-there are more reasons as to why you will never regret investing in a portable AC.

  • Easy installations

Unlike the window unit AC, the portable AC has temporal installations. Thus making it quite simple to install it or remove it. Therefore, you can easily use it across many rooms or recreational vehicles.

Actually, in most cases, you will only be needed to hook or unhook the AC. Or even better, just place it on a surface.

  • Noiseless

Over the recent past, most portable AC manufactures are incorporating a silent mode of operation.

Do you get what that implies?

You no longer have to bear with the humming sound of an air conditioner.

  • Mobility

And above all, I wouldn’t hesitate to recommend a portable AC to an RVer, because of its enhanced mobility.

Do you remember that we said that its installations and removal are effortless? Good. But to add on-

After removing the unit, it will not take you tons of energy to get it to the other RV or room. That is as a result of the usual compact design in most portable AC. Consequently, they are lightweight or even with carrying handle fitted.

How To Clean A Portable Air Conditioner

It is recommendable that you clean the  AC at least once a month and at the beginning and end of every summer season. But even before that, why is it necessary to clean the AC regularly?

  • Staying with a clogged filter may result in odor.  Filters are constructed to filter away all the debris from getting to the cooling unit. If left there for long, they are likely to decompose and result in odor.

Subsequently, run the AC in the fan mode and leave it for approximately 2 hours

Step 5; empty the filters

The filters ensure that no debris or dust particles get into the cooling unit.

To empty it, carefully remove it from the unit and shake off the dust. However, in some cases, the filter may require replacement.

The vents are the main air pathways. Thus they also need regular vacuuming.

To do that, you can use a vacuum or the hose.

Cleaning of the coils requires a weak acid. You can purchase it or use a homemade acid from lemon or vinegar.

Pour the solution into the coils and leave it for a few minutes. Later you can rinse with some clean water.
