What Size of Air Conditioner Do I Need?

Air conditioning in RV is a must, especially for people who are traveling to places with varying temperatures. In order to install an air conditioner in an RV, it is important to make the right decision regarding its size. The length of a vehicle influences your choice as powerful units are needed for large internal spaces.

A large RV may require an AC with 18,000 BTUs for better cooling across the mobile house. In fact, RVs that are large may require more than one unit. Also, ensure your chosen product is compatible with local electricity sources since power sources vary between countries RV goes and may require different sizes of fuse.

How to Choose an Air Conditioner for Your RV or Trailer?

For purchasing a unit for your RV, making the correct decision about BTUs plays an important part. BTUs tells how well an AC can cool your space. If you will be visiting a hot destination frequently, then more than 13,500 BTUs is the right pick for you. There are different types of RV air conditioners that you can choose from. These include:

Rooftop Units

These are preferred as they utilize less space in the RV and are placed into the roof. It is influenced by the external weather as the unit is cooled by the air outside. However, its installation may not be easy as it weighs more than 100 pounds.

Vent-Free

It is relatively small in size and is known for handling moist air ventilation. However, this can only be used in a dry climate.

Portable

These are the cheapest among the lot and use one or two hoses to ventilate. They occupy a large space and are not very energy efficient.

Window

This is a great option as it does not take up floor space and offers great cooling capacity. Also, it can be easily installed.

Review of the Best RV Air Conditioners

Now we're going to take a look at some of the best RV air conditioners and review their main features. With this, we're going to go over the mutual pros and cons shared by recent customers. Let's begin!

Best Overall:
Airxcel Mach 15

Airxcel 48204C866 08-0080 Mach 15 15.0 Arctic Wht Upper

Pros

  • The Product Weighs Less; Therefore, it is Easier to Install
  • The Product Features Both Cooling and Heating Capabilities
  • This Air Conditioner by Airxcel Comes at an Affordable Price
  • The 1/3 HP Fan Motor Delivers Cool Air in a Larger Area Much Faster

Cons

  • Some Complain About the Unpleasant Odor From the Product
  • There are Many Complaints From Users About the Loud Noise it Produces

What Recent Buyers Report

Most of the buyers of this product have had a positive experience with the AC. The credits go to its low cost yet efficient functioning that comes with a lightweight build. Buyers have commented positively on the ease of use and ease of installation of this AC. The easy installation has also helped many users save on installation costs. Moreover, users have also positively reviewed the AC to be great for hotter climates.

Why it Stands Out to Us

This Airxcel AC has proven to be great for RVs for a number of reasons. While it has a good BTU rating and is also lightweight and suitable for small spaces, it has other features that make it even better. For example, this product comes at a rather competitive, reasonable price. It has all the essential features as the higher priced ones, yet it is much more affordable.

Who Would Use This Most?

The AC is best for people who have to stay in hotter climates. Moreover, it is also suitable for those who do not have much prior experience with the installation and other technicalities. It is also a good choice for ones with a tighter budget.

What Could be Improved and Why?

Since the only major thing that seems to be a con of this AC is the loud noise, perhaps Airxcel could work on that. The unit is supposed to be installed in small spaces like RVs; therefore, loud noise can be highly noticeable and annoying. Therefore, this could be improved in this overall best product.

Bottom Line

To sum it up, this affordable and high-quality AC is a good option for RV. It is easy to install, has good airflow, and is highly affordable.

Runner-up:
Maxxair TuffMaxx

Maxxair 00-325001 TuffMaxx A/C Shroud-Polar White

Pros

  • It is Easy to Maintain and Clean
  • It Also has a Built-In Rear Fin Guard
  • The Product has a Sleek, White Colored Design
  • The AC is Extremely Light Weighted; Hence, Installation is a Piece of Cake
  • The Unit is Also Made With a Protective Tough UV Plastic, Making it Sturdy and Durable

Cons

  • It is Pricier than Other Models
  • Its Plastic Body May Fall Apart After Some Time of Use

What Recent Buyers Report

Recent buyers have hugely complained about the AC’s plastic parts falling apart after some time of use. This may be a lightweight AC with a compact, sleek design, but it is not the most durable product on the market. However, buyers have reported great satisfaction level with the 15000 BTU rating, huge area coverage, and easy installation.

Why it Stands Out to Us

The best part about this is that it produces extremely low sound. Therefore, this qualifies the product perfect for use in smaller spaces like RV’s where noise is a notable factor.

Who Would Use This Most?

This is great for users who have exposure to harsh outdoor conditions. It will last them a long time and will perform just as fine in easier conditions. Moreover, if you are a user with less technical experience, you can easily use this AC and install it with its lightweight built and detailed instructions.

What Could be Improved and Why?

The only thing that may need some improvements and changes is the build quality. Its build will last you if you take extreme care of it; however, with rough handling, it may not last as long. For long-term use, you may want this to be built with better quality material.

Bottom Line

Overall, this runner up unit makes up a good quality, well-performing product that comes with a unique UV plastic build. However, it is pricier than other similar competitors’ products.

Best Coleman RV Air Conditioner: 
Coleman Airxcel Mach III PS 13.5

Pros

  • Most Powerful AC Unit on the Market
  • Low Profile Look With Easy Installation
  • Trustable Brand With a Great Track Record of Excellent Customer Service

Cons

  • Not the Most Durable
  • Loud When Set to High

The Coleman Mach is among the most powerful and recommended air conditioning units on the market. Coleman is a trusted brand and has released other great products with this top of the line RV air conditioning unit.  

The Coleman Mach is a low profile unit that offers 15,000 BTUs of power to ensure your RV is cool and comfortable. As far as RV air conditioning units go, the Coleman Mach is a top of the line model at a reasonable price point.

Bottom Line

The Coleman Mach is a great deal in the mid priced units considering how powerful it is. This AC unit is a great choice for campers planning on being in very hot conditions.

Most Portable RV Air Conditioner:
Honeywell Portable Air Conditioner

Honeywell Portable Air Conditioner, Dehumidifier & Fan for Rooms Up to 400 Sq. Ft with Remote Control, HL09CESWK

Pros

  • This is a Highly Portable Product
  • It can Cover and Cool Spaces up to 300 to 400 Square Feet
  • This Honeywell Product is Well-Known for its Quiet Operation
  • This is a Highly Advanced Unit Due to its Remote Control and Digital Functionality

What Recent Buyers Report

Recent buyers seem to be very pleased with this portable RV air conditioner. It is stylish, and also offers powerful performance. Customers have highly praised it for its advanced and easy-to-use functions like the digital controls. Moreover, other than RV owners, people have also given positive reviews about the cooling power of this unit in larger rooms.

Why it Stands Out to Us

The most impressive feature about this unit is that it is highly multi-functional. It is a dehumidifier, cooling, and heating unit all in one. This makes it versatile and extremely useful in all kinds of conditions. Moreover, it is also bucket-less, which means it requires minimum maintenance. Therefore, we have added this Honeywell air conditioner on our list of some of the best RV ACs in the market.

Who Would Use This Most?

The product is extremely useful for people who travel a lot. This is because, firstly, it is portable and comes with a comfortable design. It's also low maintenance, which means that it won’t bother you during your traveling. Secondly, the AC is also suitable for more than just one condition. It is a dehumidifier for high moisture conditions, a heater for cooler climates and a cooler for hotter climates.

What Could be Improved and Why?


Even though it is considered to be a portable, travel-friendly AC, it still has a bulky weight of 64 pounds. While this might not seem to be a huge inconvenience if you plan on keeping it in one place, it will be a problem if you want to move it around. Therefore, a lighter unit may be a better option. Moreover, it is also pricey, so that area can also be improved for better affordability.

Bottom Line

This is the most diverse and versatile AC on the market. Its travel-friendly, easy to use, and also has a sleek design. The only problem is that it's pricey. However, investing in this high-quality product will be a one-time thing.

Best RV Window Air Conditioner:

  • It has Adjustable Fan and Cooling Speed Settings
  • This Unit Comes With a Mesh Filter that is Easy to Clean
  • It’s a Suitable Unit for Areas of Sizes up to 150 Square Feet

Cons

  • It has Comparatively Lower Air Flow of 101 CFM
  • It May Not be the Best for Large Rooms and Areas

What Recent Buyers Report

The 6000 BTU rating has made buyers unsatisfied for its limited area coverage. However, users who have smaller areas to cover, like RVs, are satisfied with its performance. It is also reported to be long lasting and is powerful. However, customer satisfaction is not at the greatest due to its restrictive features like the 101 CFM capability. Although, customers love it for its extremely quiet performance.

Why it Stands Out to Us

The best feature about this unit is its lowest sound production. It’s not the lowest on the market; however, it’s still very low compared to its competitors. Moreover, the low sound production makes it extremely appropriate for smaller areas like RVs. Hence, the product has made it to our list for its exceptionally quiet operation.

Who Would Use This Most?

It’s a great choice for people who have a small area to cover. It’s also not extremely expensive, so you may want to consider buying it if you have a limited budget. Moreover, the AC also has a powerful cooling system; therefore, it’s useful for those in hotter climates.

What Could be Improved and Why?

Perhaps the airflow, BTU, and the energy efficiency of the unit can be worked upon. Users have complained about it being heavy on the bills. It also has a low airflow, which makes it inappropriate for large rooms. Therefore, these features can be worked upon and improved.

Bottom Line


Overall, the AC is a good choice if you are looking for a window unit for an RV or a small space. However, for larger rooms, you may have other better options to consider. Also, you can find more diverse and versatile products in the same price range.

Best Rooftop Air Conditioner:

Cons

  • It Weighs More Than Some Other Models
  • The AC Produces Lots of Noise When It's Working at a High Speed

What Recent Buyers Report

The one feature that all customers have repeatedly complained about is the poor customer service from the manufacturer. Even though the unit comes with a 2-year warranty and is otherwise of great quality, it still has poor and unresponsive customer service. Other than that, customers are fully satisfied with the functioning of the AC and its power of cooling a small to large sized room. It’s also reviewed positively by customers due to its easy installation.

Why it Stands Out to Us

The most distinctive feature of this outstanding unit is its easy installation. Rooftop units are usually difficult to install; however, installing this unit will be a piece of cake. Secondly, it also comes in 2 different colors. This gives you a wider choice to choose from so that the unit matches better with the interior of your RV.

Who Would Use This Most?

This is an extremely useful unit for people who plan on using it for a long time. This is because first of all, it has a sturdy and durable built. It is also reviewed by customers for its long life. Second of all, it also comes with a warranty of 2 years, which gives you security for a long time.

What Could be Improved and Why?

The customer support and the noise issue of this AC can be worked on. It is highly noisy when it’s at high speed. This feature should be worked on to make the unit more appropriate for smaller areas.

Bottom Line


By weighing both the aspects of this RV rooftop unit, we can safely say that it is a good investment. Other than its comparatively heavier weight and poor customer support, the unit has lots of other beneficial features.

Moreover, customers also have not complained about its noise production, which means that the unit will cool your room without getting noticed it is there at all.

Who Would Use This Most?

It’s a good choice for small RVs and use in small areas. It’s also beneficial for people with children and pets since it is low profile and can hardly come to notice. Moreover, it is also useful for people looking for an energy efficient unit that will be easy on their utility bills.

What Could be Improved and Why?

The only thing we found to be of little inconvenience is its high price tag. Perhaps working on the price and trying to offer the same functionality in a rather affordable price range will be a good improvement.

People Also Ask

Air conditioners require a lot of technical knowledge or past experience in order to be properly utilized and maintained. Therefore, many people who do not have that kind of technical understanding have several questions regarding these products. Here, we’ve tried our best to answer frequently asked questions that customers always struggle to find answers to.

How to Clean an RV Air Conditioner?

It is important that RV air conditioner is cleaned from time to time. The condenser and evaporator fins must be cleaned every couple of years to maintain its efficiency. Over time, the cooling fins become clogged with dust and dirt.

Good spray or foaming cleaner should be used to clean debris and then use shop vac to remove the loosened dirt and dust. The vent must be covered leading down into the interior to keep the grime from sweeping down inside. A special fin comb tool should be used to straighten the fins.

What size of Generator for RV Air Conditioner?

The size of your unit will determine the size of a generator that is needed. If your unit requires 2800-3000 starting watts, and 1500-2000 running watts, then a 3000 watt RV generator will be sufficient for your air conditioner. Similarly, a 15,000 BTU unit will require a generator of more than 4000 watts.

How to Remove an RV Air Conditioner?

To remove an RV air conditioner, first, you need to remove the inside plastic cover from the RV which is completed by removing some control knobs and screws. When the cover is removed, the AC’s interior is easily accessed. The unit’s breaker should be turned off before disconnecting the wire harness.

Secondly, remove the outer plastic cover which is on the roof, and is usually held in with screws. After the unit is free from the roof, then lower it down. The help of a friend is recommended in this part.

How to Make Your RV Air Conditioner Quieter?

The noise of an RV air conditioner may disturb your sleep during the night. There may be some ways to make it quieter. In order to address this issue, it is important that the major source of the problem is identified. The noise of the unit may indicate that repairs are required. However, if the unit still continues to make noise after performing regular maintenance work, then there may be a need to remove or replace a component such as a compressor or a fan motor.

How Many Amps Does an RV Air Conditioner Use?

Air conditioners are important in most RVs. They are the vehicle’s energy hogs. The amps required vary with the size of your chosen unit. A 7000 BTU rooftop AC will require around 1700 watts to start up and 600 watts to keep running. Similarly, a larger 10,000 BTU RV AC will need 2000 watts to start up and 700 watts to keep it running. Average use of electricity for a typical RV is around 20KWh a day. This makes it 608kwh a month or 7,300 kWh a year.

How to Add Freon to RV Air Conditioner?

RV air conditioners use refrigerants to pass chilled air over the evaporator coil. Units with low refrigerant levels need to add refrigerant to operate at maximum efficiency. In some systems, refrigerant levels can be topped off, or adding more refrigerant will recharge the unit.

Freon is one of the brands of refrigerants. The power must be lowered that is supplied to the air conditioner before starting to work on the unit. Then, lift the lid straight up in order to protect against damaging the coils inside the unit. By using a refrigerant gauge, the level of the refrigerant can be checked.

To add refrigerant, unscrew the port with a wrench. Then, slowly add refrigerant to the air conditioning unit. The temperature differential between the unit and the RV temperature must vary by about 20 degrees Fahrenheit after the refrigerator is added. Monitor the temperature to ensure that the unit has been charged effectively.
