Overview of RV Air Conditioner Types (From A to Z!)

RV air conditioners come in many different shapes and sizes, with many different performance levels and features.

Most AC units can be divided in various ways, including but not limited to:
- Location: From the roof to the window to under your bed, different units can go in many different places.
- Control method: Some units must be controlled manually, while others can be operated with a thermostat.
- Cool air delivery: While some units simply dump the cold air into a room (ductless), others include systems that can transport the air to different places in the RV (ducted).
- Power source: Some RV air conditioners run on shore power or a generator, while others can be powered by solar energy or an inverter system.
- Design: Units vary in size, shape, and aerodynamics, with some built for low-profile installations to reduce drag, while others are designed for maximum cooling power in extreme temperatures.

Not all RV air conditioner types fit into just one category — many features can overlap. For example, a rooftop air conditioner can be either ducted or ductless. Similarly, an AC unit could be designed for roof installation while also offering thermostat-controlled operation or running on different power sources, such as shore power or a generator. These overlapping features allow RV owners to choose a system that best fits their specific needs and setup.

RV Air Conditioner Types

When it comes to keeping your RV cool, there’s no one-size-fits-all solution. Different types of air conditioners work differently, offer unique benefits and drawbacks, depending on your RV size, travel style, and budget. Below, we’ll break down the most common types of RV air conditioners so you can find the best fit for your needs.

1. Basement RV Air Conditioners

Basement air conditioners are a less common but highly effective cooling option for larger RVs, particularly Class A motorhomes and high-end 5th wheels. Unlike traditional rooftop units, basement ACs are installed underneath the RV, usually in a storage bay or an enclosed compartment near the chassis.

Pros:
- No Additional Height: Unlike a rooftop unit, a basement air conditioner will not make your RV any taller, so you won’t have to worry as much about bridges or low-hanging branches.
- Quiet: Since the unit is tucked away in the basement, it doesn’t create much noise in the RV’s living area.
- Easy Access: If you need to perform maintenance, a basement unit is relatively easy to get to. You won’t have to use a ladder like you would for a rooftop unit!

Cons:
- Limited Availability: Basement ACs are less common than rooftop models, which can make replacement parts and service harder to find in certain areas.
- More Complex Installation and Maintenance: Proper installation and insulation are essential for optimal cooling efficiency.

Benefits of RV Basement ACs

One of the biggest advantages of a basement RV air conditioning system is the lower profile it allows for your RV. By eliminating the need for rooftop units, basement ACs reduce overall vehicle height, making it easier to navigate low-clearance areas like tunnels, overpasses, and heavily wooded campsites. Additionally, since the unit is housed beneath the RV, it frees up valuable rooftop space for solar panels or pop tops.

Noise reduction is another key benefit. Because the compressor and fan are tucked away in a lower compartment, RV basement ACs tend to operate more quietly than their rooftop counterparts. This means less noise inside your RV, allowing for a more peaceful camping experience.

The last benefit of a basement air conditioner is its easy access for maintenance. Unlike rooftop units that often require a ladder or special tools to reach, an RV basement AC is conveniently located in a lower section of the RV, making it much easier to perform routine checks or repairs. This accessibility can save time and effort, especially during the off-season or when dealing with smaller maintenance issues.

Potential Drawbacks of Basement ACs

While basement air conditioners offer many advantages, they aren’t without their drawbacks. One consideration is the limited availability of these units compared to traditional rooftop models. Because they are less common, replacement parts and service may be harder to find in certain areas.

Installation and maintenance can also be more involved. Since the unit is housed in an enclosed compartment, accessing it for repairs or servicing may require more effort than simply climbing onto the roof. Additionally, because basement ACs typically integrate with a ducted system, proper RV air conditioner installation and insulation are crucial for efficient cooling.

Is a Basement AC Right for You?

If you own a larger RV and prioritize a lower profile, quieter operation, and evenly distributed cooling, a basement air conditioner could be an excellent choice. However, if availability, serviceability, and upfront cost are concerns, you may want to weigh other options before making a decision.

2. Ducted RV Air Conditioners

A ducted RV air conditioner is designed to distribute cool air throughout the rig using a network of ducts built into the ceiling or floor. These systems are commonly found in larger motorhomes, 5th wheels, and travel trailers, offering a more efficient and even cooling experience compared to non-ducted units. This setup allows for multiple air outlets, ensuring that all rooms—such as the bedroom, kitchen, and living area—receive consistent airflow. Some ducted systems also include adjustable vents, giving RV owners more control over where air is directed.

Pros:
- Better Air Flow: The ducts can carry cool air throughout the RV, evenly distributing it rather than dumping it all out in one location. This can prevent both cold and hot spots in your living area.
- Quiet: Ducted systems tend to be a little quieter than ductless systems due to how they distribute air.

Cons:
- Energy Efficiency: Ducted systems require more power to push air through ducts and multiple vents, which can be a concern for RVers with limited electrical capacity or who rely on generator power.
- Cost: Ducted systems tend to cost more than ductless systems, both in their standalone prices and their installation costs.
- Complex Maintenance: The extent of the duct system means that it’s harder to service it, and even harder to replace it if need be.

Benefits of Ducted AC Systems

One of the biggest advantages of a ducted RV AC unit is its ability to provide even cooling throughout the RV. Instead of relying on a single, high-powered vent, the cool air is spread out across multiple zones, reducing hot spots and creating a more comfortable living environment.

Ducted RV ACs are also quieter than non-ducted systems. Because the air is pushed through vents rather than blasting from a single unit, the noise level inside the RV is significantly lower. This can make for a more pleasant experience, especially in sleeping areas where a loud AC could be disruptive.

Potential Drawbacks of Ducted RV AC Units

While ducted RV air conditioning systems offer excellent cooling performance, they also have some downsides. One of the main drawbacks is energy efficiency—because the system has to push air through ducts and multiple vents, it may require more power to maintain the desired temperature. This can be a concern for RVers who frequently rely on generator power or have limited electrical capacity.

Installation and maintenance are also more complex than with non-ducted systems. Ducted ACs require a built-in ductwork system, which means they’re not easily added to RVs that weren’t originally designed for them. Additionally, if there’s a problem with the ducts—such as leaks, blockages, or poor insulation—it can lead to reduced cooling efficiency and require professional servicing to fix.

Is a Ducted RV AC Right for You?

If you have a larger RV or want a quieter, more evenly distributed cooling system, a ducted RV air conditioner is a great option. However, if you prefer a simpler system that’s easier to install and maintain, a non-ducted AC might be a better fit. Ultimately, the choice comes down to the size of your RV, your cooling needs, and how much control you want over your indoor climate.

3. Non-Ducted RV Air Conditioners

Non-ducted, or ductless, RV air conditioners are self-contained cooling units that distribute air directly from the AC unit itself, rather than through a system of vents. These systems typically have adjustable louvers or vents that allow you to direct airflow in specific directions. Some models also include multiple fan speed settings and temperature controls for customized comfort. These units are commonly found in smaller RVs, campers, and travel trailers where a fully ducted system isn’t necessary or practical. Since ductless ACs operate as standalone units, they are typically installed in a central location, such as the main living area. However, in larger RVs, multiple non-ducted units can be installed in separate zones, such as the bedroom or kitchen, to increase overall cooling efficiency.

Pros:
- Easy Installation: Compared to the complex system of a ducted unit, a ductless unit is both easier and cheaper to install.
- Energy Efficiency: Ductless systems don’t have to push air through ducts, making them more efficient at directly cooling the space and reducing power consumption, which is ideal for RVers with limited electrical supply or those using a generator.
- Effective for Small RVs: A good ductless system is perfectly capable of cooling a smaller RV, and it doesn’t take up nearly as much space as a ducted system.
- Affordability: Ductless units are typically more affordable, with lower installation and maintenance costs.

Cons:
- Limited Air Flow: A ductless unit only releases cool air from one location; this can result in the space around the vent becoming cold, while locations farther away from the vent remain warm. This is especially noticeable in a larger RV.
- Noise: Ductless systems tend to be a little louder than ducted systems.

Benefits of Non-Ducted RV AC Systems

One of the biggest advantages of non-ducted RV air conditioners is their ease of installation. Because they don’t require complex ductwork, they can be mounted directly into an existing roof opening, making them an ideal option for RVers looking for a simple cooling solution.

Another major benefit is energy efficiency. Since non-ducted units don’t have to push air through a series of vents and ducts, they tend to lose less cooling power, making them more efficient at directly cooling the immediate space. This can be particularly useful for RVers looking to minimize power consumption while running their AC on generator power or a limited electrical supply.

Ductless air conditioners are also typically more affordable than their ducted counterparts. Not only are the units themselves generally less expensive, but installation and maintenance costs are lower as well. There are no ducts to clean, seal, or insulate, reducing the potential for energy loss or system inefficiencies over time.

Potential Drawbacks of Non-Ducted RV AC Units

While ductless ACs are an excellent cooling solution for many RVers, they do have some limitations. One of the main drawbacks is their limited cooling reach. Since the air is only distributed from the main unit rather than through a venting system, cooling may be less uniform, especially in larger RVs with multiple rooms or slide-outs. This can lead to uneven temperatures, with certain areas staying cooler than others.

Another downside is the noise level. Because the entire cooling process happens within the unit itself—rather than in an external or vented system—non-ducted ACs tend to be louder than ducted ones. While manufacturers have made improvements in noise reduction, the fan and compressor sounds can still be more noticeable, which might be a concern for light sleepers or those looking for a quieter RV experience.

Is a Non-Ducted RV AC Right for You?

A non-ducted RV air conditioner is a great choice if you have a smaller RV, need an easy-to-install, cost-effective solution, or want to maximize energy efficiency without worrying about ductwork. However, if you have a larger RV and need even cooling throughout multiple rooms, a ducted system might be the better option.

Ultimately, the best choice depends on your RV size, travel habits, and personal comfort preferences. If you prioritize simplicity, affordability, and efficiency, a non-ducted AC system could be the perfect fit for your cooling needs.

Ducted vs. Non-Ducted RV Air Conditioners

Ducted and non-ducted (ductless) RV air conditioners differ primarily in how they distribute cool air throughout the space. Ducted AC systems use a network of vents and ducts to evenly distribute air across multiple zones, making them ideal for larger RVs or those with multiple rooms. This setup provides a clean, streamlined look and allows for more consistent cooling, but it can also require more power and maintenance due to potential energy loss through the ducts.

On the other hand, non-ducted ACs deliver cool air directly from the unit itself, making them a great option for smaller RVs or areas that don’t require extensive air circulation. These units are generally more energy-efficient, easier to install, and less expensive upfront, but they may create uneven cooling in larger spaces and can be more visually obtrusive. Ultimately, the choice between ducted and non-ducted ACs depends on your RV size, layout, and cooling preferences.

4. RV Evaporative Coolers

RV evaporative coolers, often referred to as swamp coolers, offer an alternative to traditional RV air conditioners by using the natural process of water evaporation to cool the air. Instead of relying on refrigerants and compressors like conventional AC units, these systems pull warm air through water-saturated pads, causing the air to cool as the water evaporates. The result is a steady flow of cooler, more humid air that can help maintain comfort in dry climates.

Pros:
- Energy Efficient: Evaporative coolers are far more energy efficient than most air conditioners, often using significantly less electricity. This can be especially helpful if you don’t have a regular source of electricity – or if you’d rather not pay for so much power.
- Low Cost: Evaporative coolers tend to be cheaper than most AC units. The reduced amount of electricity you’ll use may also save you some money.
- Portable: Most RV evaporative air coolers are easy to move around as needed. Some can be as small as a shoebox!

Cons:
- Regular Water Replacement: The damp pads used to cool the air won’t stay damp forever. You will need to regularly replace the pads and the device’s water levels to keep it working properly.
- Additional Moisture: The RV evaporative cooler can only comfortably work in dry climates, as the moisture it adds to the air increases the humidity. If you’re traveling through a muggy swamp, this device isn’t going to help you stay cool.
- Less Precise Temperature Control: Evaporative coolers offer less accurate temperature regulation compared to traditional AC units, making it harder to reach a specific desired temperature.
- Requires Ventilation: These systems need constant airflow to work effectively, so RVers may have to leave windows or vents open.

Benefits of Evaporative Coolers for RVs

One of the biggest advantages of a portable air cooler for an RV is its energy efficiency. Since it relies on water evaporation rather than a high-powered compressor, it uses far less electricity than traditional AC units, making it an excellent option for RVers looking to conserve battery power or run their cooling system on solar energy.

Another benefit is that it increases humidity inside the RV, which can be particularly helpful in dry climates where low moisture levels can cause discomfort, dry skin, and respiratory irritation. On top of that, because the system is relatively simple and doesn’t rely on complex mechanical components like compressors, the long-term maintenance and operating costs tend to be lower than those of a conventional air conditioner.

Potential Drawbacks of RV Evaporative Coolers

While evaporative air coolers work well in hot, dry climates, they are much less effective in areas with high humidity. Because they cool by adding moisture to the air, they lose efficiency when the air is already saturated with moisture, making them less practical for regions where humidity levels are consistently high.

Another drawback is the need for a steady water supply. Since the system depends on water-soaked cooling pads, it requires frequent refilling, which can be inconvenient for RVers who camp in remote areas without easy access to water. Some models can connect directly to an RV’s onboard water system, but this may not always be feasible.

Unlike traditional air conditioners with adjustable thermostats, evaporative air coolers for RVs also offer less precise temperature control, making it difficult to achieve a specific desired temperature. Additionally, because these systems require constant airflow to function properly, RVers often need to leave windows or vents open to maintain circulation, which can be a disadvantage in extreme heat when keeping the RV sealed off is preferred.

Is an Evaporative Cooler Right for Your RV?

An evaporative cooler can be a great option for RVers who primarily camp in hot, dry climates and want to reduce energy consumption by using a cooling system that requires minimal power. It’s also a solid choice for those who rely on solar energy or prefer an eco-friendly alternative to traditional air conditioning. However, for RVers who travel through areas with high humidity, need precise temperature control, or don’t want to worry about refilling water, a more conventional AC system might be the better investment.

5. RV Air Conditioners with Heaters

Some RV air conditioning systems are designed to provide both cooling and heating, making them versatile solutions for year-round travel. These dual-function units allow RVers to stay comfortable in a wide range of temperatures without needing to install a separate heating system. Most commonly, heating and cooling RV AC units operate using a heat pump or resistance heating elements, each with its own advantages and limitations.

1. Heat Pump Function: Many RV AC units that offer heating rely on a heat pump, which essentially works like an air conditioner in reverse. Instead of removing heat from inside the RV and releasing it outdoors, the heat pump extracts warmth from the outside air and brings it inside. This process is energy-efficient and works well in mild to moderately cold temperatures.
2. Electric Heating Element: Some units, particularly those found in ducted systems or high-end rooftop ACs, incorporate an electric resistance heating element. This functions similarly to a space heater, using electrical power to generate heat. While effective, it consumes more energy than a heat pump and is generally better suited for situations where shore power is available.

Pros:
- Two-Devices-in-One: A heating and cooling unit both cools and heats the RV interior as the outside temperature demands. This provides a convenient alternative to operating two separate devices.
- No Propane Needed: Most RV furnaces are fueled by propane, while a heating and cooling unit uses electricity. Heating your RV with the unit will save you quite a bit of propane – and if you’re at a campground where electricity is included in the price, it could also save you quite a bit of money!

Cons:
- Cost: Given the additional equipment involved, heating and cooling units tend to be more expensive than other air conditioners.
- Limited Heating Ability: Since these units warm the RV by drawing heat in from outside, they don’t really work when it’s freezing. The point of no return depends on the model; generally, if it’s 40°F or lower, you will need another heat source.
- Energy Use: Heating and cooling units use a fair bit of power; if you’re using a generator, you’re probably going to need some extra fuel on hand.

Benefits of RV Air Conditioners with Heaters

One of the biggest advantages of an RV AC unit with a heater is convenience. Instead of having to rely on separate systems for heating and cooling—such as an AC for summer and a propane furnace for winter—RVers can enjoy a single, all-in-one solution. Heat pumps, in particular, are highly energy-efficient, especially when compared to propane furnaces, since they transfer existing heat rather than generating it. This makes them a cost-effective choice for RVers who frequently stay at campgrounds with electric hookups.

Another benefit is that these systems provide a cleaner alternative to propane heating, as they do not produce combustion byproducts such as carbon monoxide. They also offer quiet operation compared to some traditional RV furnaces, making them ideal for light sleepers.

Potential Drawbacks of RV ACs with Heaters

Despite their advantages, heating and cooling AC units have limitations. Heat pumps become significantly less effective in very cold temperatures, typically struggling to provide adequate warmth when the outside air drops below 40°F. In freezing conditions, they may need to be supplemented with a propane furnace or portable heater.

Additionally, electric resistance heating elements, while effective, consume a lot of electricity, making them impractical for boondocking or off-grid camping unless a generator or high-capacity battery bank is available.

Another consideration is cost—RV AC units with integrated heating functions tend to be more expensive upfront compared to standard cooling-only models.

Is an RV Air Conditioner with a Heater Right for You?

If you frequently camp in mild to moderately cold climates and want a versatile system that provides both heating and cooling without relying on propane, a heat pump-equipped AC unit could be a great investment. It’s especially beneficial for RVers who spend most of their time at full-service campgrounds with shore power.

However, if you often travel in extreme cold or rely on off-grid camping, a traditional propane furnace may be a more reliable heating option, either as a backup or primary source. Before choosing a heating and cooling RV AC system, it’s important to consider your travel habits, energy availability, and budget to determine if this dual-purpose setup is the right fit for your needs.

6. Low-Profile RV Air Conditioners

Low-profile RV air conditioners are designed to offer all the cooling power of a standard AC unit, but in a more compact and streamlined design. These units are ideal for RVers looking to minimize the impact on their rooftop setup while still maintaining optimal performance.

Low-profile RV AC units operate in much the same way as standard RV air conditioners, using refrigeration cycles to cool the air inside the RV. However, the major difference lies in the design of the unit itself. Low-profile ACs typically use a smaller, more efficient compressor and condenser system that allows for a more compact structure. The reduced height of these units helps with aerodynamics, minimizing wind resistance and improving fuel efficiency while driving.

Pros:
- Compact Design: A low-profile RV AC unit is far shorter than most rooftop units. Avoiding the additional height can be very important for those with taller RVs – you don’t want to hit a bridge or tree branch on the way to the campsite!
- Aerodynamic: Low-profile units are lighter and more streamlined than most rooftop units, which can improve your RV’s fuel efficiency.
- Efficient: Despite their smaller size, low-profile units can be just as effective at cooling as traditional rooftop units.

Cons:
- Lower Cooling Capacity: The smaller size of low-profile ACs often means reduced cooling power, which may not be sufficient for larger RVs or extreme heat.
- Limited Cooling Area: Due to their compact design, they may not provide even cooling throughout larger spaces, leaving certain areas less comfortable.
- Higher Upfront Cost: The specialized design of low-profile units can make them more expensive compared to larger, standard RV air conditioners.

Benefits of Low-Profile RV ACs

One of the most notable advantages of low-profile AC units is their ability to blend seamlessly with the RV's roofline. This sleek appearance reduces the visual bulk typically associated with traditional air conditioning units, which is particularly appealing for RVers who value aesthetics. The smaller size also reduces wind resistance, potentially improving fuel efficiency on long trips.

Another benefit is their ability to fit into tighter spaces. Low-profile units are often a better fit for RVs with limited rooftop space or for owners who want to avoid adding too much weight to the roof, which can affect handling and stability.

Finally, these units are often equipped with energy-efficient components, meaning they can cool the RV effectively while using less power. This is especially beneficial for RVers who frequently camp in places with limited electrical hookups, as low-profile units can help reduce the strain on batteries or generators.

Potential Drawbacks of Low-Profile RV Air Conditioners

While low-profile RV ACs have many advantages, they are not without their drawbacks. Because these units are smaller and more compact, they often have a lower cooling capacity than larger, standard RV air conditioners. This can make them less suitable for very large RVs or for areas with extreme heat, where more powerful cooling may be required to keep the interior comfortable. The compact size also means that the cooling area is generally more limited, so they may not be as effective in maintaining even temperatures throughout larger spaces.

In some cases, these units may also be more expensive upfront than their larger counterparts due to the specialized components and engineering involved in creating a more compact system.

Is a Low-Profile RV AC Right for You?

If you have a smaller RV or are looking for a system that combines effective cooling with a sleek, aerodynamic design, a low-profile air conditioner could be the perfect fit. These units are well-suited for RVers who prioritize aesthetics and fuel efficiency, especially those who frequently travel on long road trips where minimizing wind resistance can make a difference.

However, if you have a larger RV or plan to camp in areas with extreme heat, you might find that a low-profile AC system doesn’t provide enough cooling power for your needs.

7. Manual RV Air Conditioners

Manual RV air conditioners are the traditional choice for cooling your RV, offering simple, straightforward operation without the complexity of advanced features. These units are designed for users who prefer hands-on control and the flexibility to adjust their air conditioning to their exact needs.

Unlike modern systems with digital thermostats or remote controls, manual air conditioners rely on physical dials or knobs to control settings such as temperature, fan speed, and airflow direction. While they lack the convenience of automatic adjustments, manual units remain a reliable and cost-effective solution for many RV owners.

Pros:
- Simple Operation: The unit’s controls are easy to use; if you can push a button, you can use it!
- Reliable: Since there are fewer electronics involved in a manual air conditioner, the chances for malfunctions are slim.
- Low Cost: Manual units generally cost less than electronic models.

Cons:
- No Remote Control: Manual air conditioners cannot be controlled by a thermostat or remote, requiring you to change the settings by hand. If the unit is not easily accessible, this may be inconvenient.
- Limited Temperature Precision: Since manual air conditioners don’t have thermostats, the temperature control is far less precise than in electronic models.
- No Smart Features: Manual air conditioners can’t be integrated with smart home or RV automation systems.

Benefits of RV ACs with Manual Control

The biggest advantage of an RV AC unit with manual control is its simplicity and reliability. These units are often the most affordable option for RV owners, as they lack the advanced electronics and sensors of more modern systems. This makes them an appealing choice for budget-conscious RVers who want a dependable cooling solution without the added expense of high-tech features.

Manual AC units are also easier to repair and maintain compared to their automatic counterparts. Because they don’t rely on digital components or advanced sensors, troubleshooting issues with manual systems is often a simpler process, and repair parts are usually more readily available and cost-effective. For those who prefer a hands-on approach to maintenance, manual air conditioners offer fewer complications and easier access to components.

Potential Drawbacks of Manual RV Air Conditioning Systems

One of the main drawbacks of manual RV air conditioners is the lack of automation and convenience. While you have full control over the settings, you also need to monitor and adjust the system regularly, which can be inconvenient, especially when you're dealing with fluctuating outdoor temperatures. You may have to adjust the fan speed or temperature multiple times a day to maintain your desired comfort level, especially in extreme weather conditions.

Manual units also lack some of the energy-saving features found in more modern systems. Without the advanced thermostats or temperature sensors of automatic systems, manual air conditioners often run continuously at the same setting, which can lead to increased energy consumption. This could be a disadvantage for RVers who are relying on limited power sources, such as a generator or battery, during their trips.

Is a Manual RV AC Right for You?

A manual RV air conditioner may be the perfect choice for you if you’re looking for a no-frills, budget-friendly solution that provides reliable cooling without the need for advanced technology. If you don’t mind making regular adjustments to keep the temperature just right and prefer the simplicity of a more traditional system, a manual air conditioner can offer great value. These units are particularly well-suited for RV owners who don’t plan on using the air conditioning for long periods or in extreme weather conditions, where more constant adjustments might be needed.

However, if you value convenience, automation, and energy efficiency, you might want to consider more advanced systems that offer digital controls and automatic temperature regulation. If you frequently travel in areas with extreme temperatures or plan to camp for extended periods, an automatic system could provide more consistent comfort with less effort on your part.

8. Mini Split RV Air Conditioners

Mini split RV air conditioners offer a modern and highly efficient way to cool and sometimes heat your RV. The mini split system works by circulating refrigerant between the indoor and outdoor units. The indoor unit pulls warm air from the RV, cools it using the refrigerant, and then distributes the cooled air throughout the RV. The outdoor unit functions as the heart of the system, housing the compressor, condenser, and fan. This setup allows the indoor unit to operate quietly, with most of the noisy mechanical components located outside the RV.

Pros:
- Energy Efficient: Mini splits are known for their high energy efficiency, consuming less electricity than rooftop units while maintaining equivalent cooling power.
- Quiet: Mini split AC units are usually quieter than many other air conditioner types.
- Flexible Installation: Without the need for large ducts, mini splits offer more efficient use of space and can be installed in custom RV layouts with ease.

Cons:
- Complex Installation: Mini splits can be very complicated to install. You not only need to connect the two units, but you need to find a place where you can secure your outside unit without risk of it being damaged on the road (many choose their trailer tongue or a modified basement area).
- Cost: Mini split systems can be expensive to both purchase and install.
- Significant Space Needed: Since mini split systems consist of two units and the components that connect them, they take up a significant amount of room and weigh more than most air conditioners.

Benefits of a Mini Split AC for Your RV

One of the major benefits of mini split RV AC systems is their efficiency. Unlike traditional RV air conditioners, which often rely on a single compressor to cool the entire space, mini splits provide targeted cooling. The indoor unit can be installed in the optimal location for even air distribution, ensuring that every corner of your RV receives consistent and comfortable temperatures.

Mini split systems are also more energy-efficient than conventional RV air conditioners. Their inverter-driven compressors adjust the speed according to the cooling demand, which minimizes energy consumption. This is especially beneficial for RVers who rely on limited power sources, such as solar or a generator, as mini splits can cool the space more effectively without wasting energy. The system’s ability to run at varying speeds helps to reduce power draw and ensures that the air conditioning doesn’t run at full power unnecessarily.

Additionally, because the outdoor unit handles the noisy components, mini splits tend to operate more quietly, which is a significant advantage for those who value a peaceful, noise-free interior environment.

Another major benefit is the flexibility of installation. Mini splits do not require large ducts, allowing for more efficient use of space. The indoor units can be mounted in various locations, and the refrigerant lines are relatively easy to route. This makes mini split systems ideal for custom RV layouts where traditional ductwork might be impractical.

Potential Drawbacks of Mini Split Air Conditioners for RVs

Despite their numerous benefits, mini split air conditioners on RVs do come with some drawbacks. One of the main concerns for RV owners is the installation process. While the system itself is relatively easy to maintain, installation can be complex and may require professional assistance. For some RV owners, this added complexity may be a barrier to choosing this type of system.

Another potential drawback is the initial cost. Mini split systems tend to be more expensive than traditional rooftop air conditioners or manual units. While energy efficiency and long-term savings may offset the upfront cost over time, the higher price point can be a consideration for budget-conscious RVers. Additionally, because these systems are more advanced, repairs or replacements may also be more costly compared to simpler models.

Finally, mini split systems require significant space for both the indoor and outdoor units, as well as the connecting components. This can be a disadvantage in RVs with limited space, as it may require careful planning and installation to accommodate both units. Additionally, mini splits are heavier than most other air conditioning options, which could impact the overall weight of your RV and its capacity to handle additional load. This added bulk and weight may not be ideal for RV owners looking to maximize space and minimize weight.

Is a Mini Split AC Unit on Your RV Right for You?

A mini split air conditioner is an excellent option for RV owners who prioritize comfort, energy efficiency, and quiet operation. If you plan to travel frequently or live in your RV for extended periods, the ability to both cool and heat the interior in a compact, quiet, and energy-efficient manner can make a significant difference in your overall experience. The flexibility of installation and the ability to customize the temperature in different zones also makes mini splits ideal for those with custom RV layouts or specific cooling needs.

However, mini splits are not for everyone. If you have a limited budget, the higher upfront costs and installation complexity may make traditional systems a more appealing option. Likewise, if you don’t need the advanced features of a mini split or only occasionally use air conditioning, simpler, more budget-friendly systems might be sufficient.

9. Multi-Zone RV Air Conditioners

Multi-zone RV air conditioners are an innovative solution for RV owners who want the flexibility to control the temperature in different areas or zones of their vehicle independently. These systems are designed to cool or heat multiple zones within the RV, offering targeted climate control for different living spaces.

A multi-zone system typically includes a central unit connected to multiple indoor air handling units, each of which controls a specific zone. These systems provide an advanced level of comfort and customization, making them ideal for RVs with multiple rooms or areas where different temperatures are preferred.

A multi-zone AC system is typically controlled through a central control panel or remote, allowing users to easily adjust settings for each zone based on individual needs. This setup is especially beneficial for larger RVs, such as fifth wheels or motorhomes, where different living spaces have different temperature requirements.

Pros:
- Different Room Temperatures: Multi-zone systems let you make different spaces in the RV cooler or warmer via a single thermostat. If you need your bedroom to be nice and cool to sleep but don’t want to freeze out your family in the living room, this can be very handy!
- Useful for Larger RVs: When you have a larger RV with multiple units to keep it cool, it can be nice to have a single device that controls them all, rather than needing to run around and adjust them separately.
- Energy Efficient: Multi-zone systems make it easy to not waste energy on cooling unoccupied spaces in the RV, saving you electricity (and money)!
- Convenience: Multi-zone systems allow for precise temperature adjustments in different areas of the RV. Instead of cooling the entire space at once, you can tailor the climate to your preferences, keeping specific zones cooler or warmer as needed.

Cons:
- Cost: Multi-zone systems are far more expensive than other air conditioning systems, due to both the multiple components and the extensive installation involved.

- Medium RVs: 9,000 to 13,500 BTUs
- Large RVs: 13,500 to 18,000+ BTUs

It’s important to get an air conditioner unit with an appropriate BTU rating for your RV. If you have a larger motorcoach, 6,000 BTUs won’t be enough to cool the entire space. And if you get a unit with 14,000 BTUs for your small campervan, you’ll likely be shivering all night!

2. Size & Layout of the RV

As previously stated, larger RVs will require more powerful air conditioners to properly cool their interiors, so keeping your RV’s size in mind is a good idea. If your RV is exceptionally tall, you should make sure your chosen unit isn’t going to get swiped off the roof by a tree branch while on the road. You could use a low-profile air conditioner or a non-rooftop unit.

If you want an air conditioning system with ducting, check that your RV will have the space for all the components involved.

Another detail you may want to consider is your RV’s insulation. The more insulated your RV is, the easier it will be to cool it and the less powerful of an air conditioner you’ll need. Remember that windows can play a role; more windows mean more sunlight which means more heat, and that’s not even considering if the windows are properly sealed.

3. AC Control Method

RV air conditioners can be controlled either manually, by remote, or via a thermostat. Depending on where the unit is and your own technological preferences, you may have a partiality towards one method of operating your unit over others.

4. AC Power Consumption

Some RV air conditioners consume more power than others, and you’ll need to make sure your RV’s electrical system can handle it. While small units take up around 1,000 watts, larger units can consume 2,500 watts or more. This can be especially important to consider if you want to take your RV boondocking or otherwise won’t have readily available power sources for overnight trips.

5. AC Noise Level

Some RV air conditioners are louder than others. If you’re a light sleeper or are otherwise easily annoyed by loud noises, you may want to consider one of the quieter models.

6. AC Energy Efficiency

Certain types of RV air conditioners are less energy efficient, such as window units. This means using more power to properly cool your RV’s interior, which increases your carbon footprint while also leaving a dent in your wallet.

7. Cost of the Air Conditioner

Naturally, you will need to keep your available budget in mind when choosing your RV air conditioner. Whether you can pay for a higher quality unit – or if you even need to – is up to you.

8. Additional Air Conditioner Features

Some RV air conditioners come with additional features, such as the heat pump (see the ACs with heat pumps section), heat strips (devices that offer supplementary heat), and the condensation pump (a device that removes condensation produced by the unit and pumps it safely outside). While these features can certainly be nice, remember that they often increase the air conditioner’s price.

9. Travel Plans

You should consider exactly where and how often you intend to use your RV. If you’re travelling in cooler climates, you may not need to splurge on a powerful air conditioner. In contrast, a powerful air conditioner may be a necessity if you go somewhere hot.

Humidity may also be a factor. Evaporative coolers might be an energy efficient alternative to air conditioning in dry climates, but in humid areas, they won’t help at all.

Finally, think about how often you will be traveling in your RV. If you use your RV consistently, a permanent air conditioner is a good investment. However, if you only use it occasionally, you might want to consider a portable or window unit, which can still get the job done while being far cheaper.

FAQs About Types of RV Air Conditioners

1. What are the different types of RV AC units?

The main types of RV air conditioners are rooftop, portable, ducted, ductless, and mini-split systems. Each type offers different benefits depending on your RV size, cooling needs, and installation preferences.

2. What is the most reliable RV air conditioner?

The most reliable RV air conditioner depends on your specific needs and the type of RV you own. However, rooftop AC units from well-known brands are considered some of the most reliable options. For off-grid travelers, 12V DC-powered units are becoming increasingly reliable, as they are designed for energy efficiency and sustainability. Ultimately, reliability is influenced by the proper installation and maintenance of your chosen unit.

3. How do I know what AC unit my RV has?

To determine what AC unit is installed in your RV, start by checking the owner’s manual or any documentation that came with your RV. If that’s not available, inspect the AC unit itself for any model numbers or brand markings. These should be located on a label or sticker on the unit. You can also look for other identifiers, such as the type of cooling system (e.g., rooftop, portable) or check with the manufacturer if you know the make and model of your RV. If needed, a technician can help you identify the unit during a maintenance check.

4. Are RV air conditioners interchangeable?

While some RV air conditioners are interchangeable, this is not always the case. The compatibility of AC units largely depends on factors such as the size of the unit, the power requirements, and the configuration of your RV’s roof or interior. For example, if you're replacing a rooftop AC unit, the new unit must match the size and mounting system of the old one. Additionally, electrical requirements (e.g., 120V AC or 12V DC power) must align with your RV’s existing electrical system. It’s always best to consult with a professional or the manufacturer to ensure that the replacement unit will be compatible with your RV.

5. What type of refrigerant is used in RV air conditioners?

Most RV air conditioners use R410A, a common refrigerant that offers higher efficiency and a lower environmental impact than older refrigerants like R22. However, some newer models are using R32 refrigerant, which is even more energy-efficient and has a lower global warming potential compared to R410A. R32 is gaining popularity due to its eco-friendliness and improved performance, but it’s important to check your unit's specifications to know which refrigerant it uses, as it can affect compatibility with older systems or parts.
