What to Look for in RV Air Conditioners

Before deciding on the quietest RV air conditioner for you, it is important to understand all the specifications and features of quiet RV air conditioner units. Here are some important specifications we will take a look to help you decide which RV air conditioner best suits your needs:

  • BTU power, cooling capacity, and noise
  • Ducter or non-ducted
  • Weight, size, and height
  • Power consumption
  • Heating extensions
  • Air purifier
  • Warranty

BTU Power, Cooling Capacity, and Noise

BTU stands for British Thermal Unit, which is a measure that helps you decide which air conditioner suits your RV based on its size and average local weather conditions. Ultimately, the final decision on which RV AC unit to buy will depend on its cooling capacity.

On average, an air conditioning unit will have around 13,500 BTU of power. This is enough power to cool down a large RV. The area isn’t the only thing to consider. Here are a few additional tips:

  • If you plan on visiting high humidity areas you will need an air conditioner with a much higher BTU power. You should generally aim to increase BTU by around 10%.
  • If the design of your RV rooms is heavily shaded, you should reduce BTU by 10%.
  • If the room’s regular occupancy is more than two persons, you should add 600 BTUs per person.

Now in regards to noise level, there is no doubt that all air conditioners make noise. The higher the BTU power, the more likely the AC is to make noise. However, many manufacturers design units to be quiet, or at least have features that permit a “quiet” mode. The units presented in this article are some of the quietest available on the market.

Getting the quietest RV air conditioner unit will allow you to have better sleep at night. If you only have small AC unit noise then it can easily blend into the background.

Ducted or Non-Ducted

There are two main types of RV air conditioners. The ducted and the non-ducted. In a ducted installation, the RV air conditioner connects to the RV’s indoor ducting system in order to distribute cold air evenly throughout the whole area of the RV. 

This is ideal for big RVs. A ducted RV air conditioner will enable you to control the temperatures of multiple rooms at once. Air passes through the duct system, usually in pipes across the RV’s floors, walls, or ceilings.

The AC unit just blows the air in whatever direction the output nozzles are facing in a non-ducted installation, they do not go through the piping. A non-ducted RV air conditioner is ideal for cooling a specific room, or a smaller RV, rather than multiple rooms. If you have a camper or motorhome, it is definitely recommended to get a ducted air conditioner as they’re practical and economical.

Weight, Size, and Height

Before purchasing an RV air conditioner, you must make sure your RV has the cargo capacity and the space for the AC unit, especially if you’re purchasing a portable one. Your RV may have limited space or weight which can become an issue.

Height is also as important since a lot of the RV air conditioner models available are rooftop A/C units. An increase in the height of an RV will negatively impact the aerodynamics and therefore fuel efficiency. Now, this is something you’ll definitely want to avoid!

Height clearance is something you should be mindful of too. If your RV is already quite tall, the additional height may result in some problems when passing through tunnels or under bridges.

Power Consumption

An RV air conditioning unit will consume a lot of energy to function which could be a cause for concern if your RV uses a portable generator. It might be better, in that case, to consider an RV air conditioner that consumes less power, allowing you to save a lot of money in the long run.

You should consider the starting & running wattage and the number of amperes that the AC unit requires to be able to match your power source with the consumption. You will need to consider the power of any heater you wish to add also.

If you travel great distances with your RV, you may also wish to consider the compatibility with the various power outlets in different countries. There are environmentally friendly options in the market too.

Heating Extensions

Some RV air conditioners are capable of providing both cooling and heating. An AC unit with a heat pump or heat strip means you can keep yourselves warm and cozy when the temperature drops in the evenings or colder months.

This is definitely useful if you like to travel throughout the whole year. However, this will of course be at an extra cost. If you only plan on using your RV during the summer, a regular RV air conditioner will suffice.

Air Purifier

Not all quiet RV air conditioners will have built-in air purifying systems. This is usually an extra feature that may be important for those who are sensitive to odors or have allergies. An air purifier works to improve the quality of air inside your RV. It will take away the risk of a health hazard, and maintain a fresh and clean breathable air environment, regardless of what the conditions are outside.


The warranty of any product is very important when investing this amount of money into something. Most air conditioner units will come with a 2-year warranty as standard, which should cover you for breakdowns and defective parts but some may only come with a 1-year. It’s completely up to you whether you look for extended warranties.

How to Find the Quietest RV Air Conditioner Unit

Choosing a quiet RV air conditioner unit involves the same principles as choosing any quiet air conditioner unit. The only thing that goes against you is size. Although you may think the bigger and more powerful the AC, the more noise it will make, which is correct. But, generally speaking, smaller AC units will weigh less and have smaller parts, which can also equate to more noise.

Average AC noise

The average air conditioner unit will be able to produce somewhere between 35dB (decibels) and 82dB depending on the model and build quality of the unit. The absolute quietest RV air conditioner will produce around 35dB, which is far less noise than a desk fan.

You should expect somewhere around 50dB for an RV unit because they’re often not fitted with the same kind of sound-dampening technology.

What works in your favor is that the fans in these units are a lot smaller which is one major noise source, and is something you can’t do much about considering all air conditioner units need to circulate air.

What Affects AC Noise Level

Just like any electronic unit, an air conditioner is always going to make some amount of noise. But, knowing which parts make the most noise will help you to choose the quietest model for you RV.

Here’s are the main noise-emitting components of air conditioner units:

  • Compressor
  • Fan
  • Installation
  • Fan motor type
  • Cooling capacity


The compressor is probably the noisiest component of an air conditioner. They do most the work, turning refrigerant into a gas. The compressor produces a lot of noise because they generally have the most moving parts.

However, you often do not need to deal with the noise as the compressor tends to be located outside of the space you’re aiming to cool, unless you have a portable model.

You may notice how noisy the compressor is if you have a home air conditioner unit, and you walk outside. But, when you’re inside you’ll notice the difference in noise as it’ll almost be silent.


The fan is located in the indoor AC unit and is the component that circulates the cool air around the room. A fan on its own can emit up to 60dB, but this will depend on a number of factors including the speed it’s running, the size of the blades, and more.


For rooftop RV air conditioner units, the installation will often involve securing the AC to the RV’s roof using bolts. This easy installation is helpful, of course, but it isn’t ideal when it comes to noise reduction as the bolts can create an effective transmission pathway for vibrations.

When the vibrations pass into the RV’s structure, they will likely enter the RV as irritable sound. That’ll make the AC unit sound louder than it actually is. To avoid this, you should choose a unit that has rubber dampeners fitted. If this is not possible, you could use fit some isolation pads.

Fan Motor Type

A quiet RV air conditioner will use either an electronically communicated (EC) motor or a permanent split capacitor (PSC) to blow air. An EC motor is capable of modulating the rotational speed of the fan in order to control the airflow. This speed variability and the modern technology allow EC motors to be quieter and more energy-efficient.

A PSC motor, on the other hand, doesn’t provide this variability. It can only either be on or off. The design is far more primitive, and, while it does the job, you may wish to avoid it if you have the choice.

Cooling Capacity

We measure an air conditioner’s cooling capacity in BTU, British Thermal Unit, which is the amount of heat needed to raise the temperature of a 1lb of water by 1 degree F. In relation to air conditioners, which cool the air, this refers to how many BTUs the unit can remove from the air in an hour.

More is not necessarily better unfortunately, as the higher the BTU, the greater air capacity the, therefore, greater noise emissions. A unit with a BTU rating too high for its space won’t work efficiently. A too-powerful unit will cool the space unevenly, leading to warmer pockets of air due to it cycling on and off too often. 

Most of the quietest RV air conditioners will typically sit between 12,000 and 15,000 BTUs. This is enough to cool a room between 550 and 1,000 square feet, which is far more than enough for an RV. This might sound too powerful, but you must factor in things like the environment, sun exposure, and ambient heat. All of these variables can add plenty extra to the necessary BTU level.

For example, you should expect to add around 600 BTU per person and up to 4,000 BTU for kitchen appliances that generate heat. Considering many RVs are single-room spaces, these numbers will start to make more sense.

Atwood 1507 Ducted AC Unit

Most Powerful Rooftop AC

  • BTU: 16,000
  • Ducted: Yes
  • Remote: Yes
  • Weight: 84 pounds
  • Dimensions: 21.82 x 15.6 x 6.36 inches
  • Warranty: 24 months

This quiet AC unit from Atwood is the most powerful AC provided in this article. This AC unit has a great BTU rating of 16,000, which is a lot higher than required to cool the inside of an RV quickly and efficiently.

While it doesn’t come with a dB rating, which I admit is annoying, many users have reviewed the product and specified how it is much quieter than other rooftop AC units they’ve used in the past. The fan can be set to low-speed mode, where users claim the fan makes almost no noise at all.

The dual motor on this quiet RV air conditioner also lets you run a condenser fan motor and a blower fan separately to adjust your cooling preference. The unit allows you to control temperature, fan speed, and the sleep timer with its wireless remote. It boasts a digital temperature readout to allow you to know exactly what you’re setting it to.

Potentially the only real negative with this product is that it’s only compatible with ducted systems. Therefore, if you have a non-ducted air conditioner system in your RV, you will need to look for a different product.

Note: Atwood does an equivalent non-ducted model.

One feature that some users tend to point out and dislike is the permanent fan setting. The fan runs all the time, even when the condenser is turned off. While this isn’t a significant issue, it may seem a bit pointless to some.

Also, the unit doesn’t use normal thermostat wiring. However, the rest of the installation is very easy, so just be sure to get some help with the wiring if you’re unsure what to do.
