How Do RV Air Conditioners Work

RV camping is one of the most luxurious ways of traveling for people that have the travel bug. You’re essentially taking a smaller version of your house with you, and with every house, you have an A.C. The air conditioners are the put RVs over most modes of travel, and hence knowing their complexities is important too. Knowledge of how RV air conditioning works will help you keep your trailer cool, and A.C working non-stop throughout your trip.

Figuring Out How Do RV Air Conditioners Work

The basic working of your air conditioners is something you’ve learned in your science classes when you were in elementary school. A. C’s push hot air out, and through cooling of the air inside the appliance, it circulates it within the room, or in this case the RV. The appliance consists of a compressor, condenser, evaporator, and canisters of refrigerant coolants that cool the air within the area where they are placed.

 A more in-depth working of the appliance will help understand how it works. Getting to know how to do air conditioners work will help RV owners to keep their appliances in check, and also help them understand if any technicalities get involved. Your Air conditioner requires a lot of power, and a lot of upkeep to run to its maximum output, which is why understanding its mechanics is something that every RV owner should be briefed on.


 The evaporator vaporizes the water in the trailer and stores it in a filter. The surrounding air is moved through the filter, which results in the cooling process. The whole process depends on the ambient temperature and humidity of the environment. The effectiveness of the evaporator depends on the surrounding climate of the area. If the humidity is more than 85%, then the evaporator is rendered useless.

Efficiency of Evaporator

 The evaporator takes up a lot of energy because of the ambient temperature. If the humidity is more than 85%, then the evaporator is rendered useless and will be less effective in cooling the RV. The evaporator system is good for hot and arid road trips, where you won’t see vegetation for miles on end. If your road trips have any places with standing water, and heavy vegetation, then the working of the evaporator will become hindered because of the surrounding conditions.

Make it Last Longer

You’ll have to get your evaporator checked up annually for service and change the filter. The filter will become damaged over time and will need replacing. Shutting down your evaporator when going through a humid area is the best course of action to keep it sustained for the longest amount of time so that the filter will have an extended life, and the RV battery will last longer as well. The working of the evaporator is simpler, which is why it won’t demand much upkeep from the owner.


The more widely used air conditioners within the trailer community, and generally everywhere. The compressors liquefy the gaseous refrigerant through the use of electricity. The liquid is turned into a gas again in another container by passing through some pipes, and this gas cools the whole RV. The compressor takes in heat from the environment. The refrigerant is taken in through the A.C once again, where the whole process starts once again.

The compressor essentially takes out hot air and lets in cool air into the vehicle interior. The compressor keeps circulating the same air, through dehumidification. The compressor isn’t dependent on the atmospheric conditions of its surroundings and is quite suited to do its job of cooling the RV. With an understanding of how RV air conditioners work, you can appreciate the complexities that go into it.

Consistent Compressors

Consistent Compressors

The compressor is quite consistent in its cooling and is mostly unfazed through atmospheric conditions. If your compressor is attached to a heating system, then it can be used for warming your RV too. The major drawback of compressors is that they are quite heavy on your electrical system. Unless you’ve plugged it into a heavy AC source, or have an adequate energy source found within your RV, you won’t be able to use the compressor to its full potential.

Energy Efficiency of Compressors

Depending on the model of your compressor, you can keep your trailer cooler for longer periods, with less energy drainage. Newer models are more efficient in using energy so make sure to fit a new one if your budget allows it. Due to the working of the compressors, they are usually the valid choice of choosing air-conditioners within the trailer. The only other problem that the RV owners have to face is the energy requirements of the compressors.

For compressors to work at their full efficiency, you must have to check annually.  The refrigerant coolants will deplete over time, and getting them refilled before a big trip is always a good idea. The compressors have a much more complex system. Depending on the model, and the condition of the compressors, they have a tendency to break down, which is why keeping them maintained is the best thing to do to keep them functioning.


Air conditioning is one of the world’s greatest inventions if I do say so myself, and to use such a useful appliance in your RV is something to be thankful for. Most of your RVs come with air conditioners, and it’s your choice which one to install. Even though the obvious choice is the compressor, which cools your whole RV quite effectively, the evaporator still has its uses.

If you’re on a budget and are more prone to visit arid climates, then evaporators do come in handy. All in all, knowing how your air conditioner function help in choosing the superior choice, and making sure to keep them maintained. Being mindful of your air conditioner’s working will help you to use it more effectively, and will let you enjoy the cool breeze to your heart’s content!
