RV air conditioner guide
Summer trips are the best season for those who like to go out and camp for leisure, and for those of us who enjoy camping outdoors, the ability to turn on the air conditioning is one way we can enjoy it no matter how far away from home we are. When you are camping in the middle of nowhere, for those of you who want to go camping or have an RV without air conditioning, you can keep yourself cool at all times by using RV ac. So the AC camper unit will be a good choice for users, allowing you to effectively cool off the heat during the warmer camping season.
As a loyal RV camper fan, you may spend most of the summer on the road, so air conditioning is essential.
How do RV air conditioners work?
RV air conditioners work by removing heat rather than producing cool air. This is accomplished by a closed-loop air conditioning system that consists of several components that work in a precise sequence.
First, the compressor is used to circulate, heat, and compress the refrigerant vapor in the air conditioner. The vapor is pressurized at high pressure to release heat in the condenser.
The condenser then removes heat from the air and pushes it out of the vehicle, where the refrigerant vapor cools before returning to a liquid state.
The evaporator takes the cold liquid from the condenser and absorbs all the heat from the RV’s warm air. This causes the liquid to expand, and when the liquid has absorbed enough of the RV’s heat, it turns back into steam.
The superheated vapor is drawn into the compressor and the cycle repeats.
Components of an RV Air Conditioner
An RV air conditioner consists of a compressor, condenser, evaporator, wiring that connects the components, an air moving system, a fan that pushes air through the condenser, and a fan that pushes air through the evaporator.
What size air conditioner do I need for my RV?
The size of the air conditioner depends on the size of the RV being driven. Air conditioners are measured in BTUs, and the more BTUs, the more powerful the air conditioner. RV air conditioners typically range from 11,000 to 15,000 BTU. Therefore, the longer the RV, the more BTUs are required for cooling.
RV Air Conditioner Type：
Ducted RV air conditioners are used in RVs that have multiple ducts in the ceiling. This allows the RV to run multiple air conditioners that distribute cool air through the walls, ceiling and floor. Ducted units are more expensive because they provide more consistent cooling throughout the RV. They are also quieter to run.
Ductless units are used in smaller RVs. They are often installed in windows, wall openings, or on top of RVs. When the ductless unit is running, it cools the room by simply blowing the cool air from the AC out of the unit’s bottom vent. The vents are directional and easily accessible. Common ductless installations include undermount, window, or rooftop air conditioners.
How long does an RV last?
The life expectancy of an RV air conditioner depends on three factors:
(1) The temperature of the weather when the RV air conditioner is running.
(2) Frequency of use of RV air conditioner
(3) The best durability of RV air conditioners
How to maintain an RV air conditioner?
Clean the filter:
Proper airflow is key to an air conditioner’s efficient operation. Filters in air conditioners help remove particles that enter the condenser. If your filter is dirty, airflow to the condenser will be slower and the cooling process will be slower.
Clean the outdoor coil:
An external air exchange is a set of fins over which a fan blows air to remove heat. If they become clogged, the air conditioner will be less effective. It is best to check the appearance once a year.
Insulate doors and windows:
Windows and doors are the number one source of heat entering your RV in the summer. Be sure to keep them closed and install curtains.
Customers when purchasing an air conditioner:
We believe that power is the most important consideration when buying an RV air conditioner. RV air conditioner capacity is measured in BTU or British Thermal Units. Most units will have a capacity of 13,500 BTU. So relatively speaking, those who spend a lot of time in hot places will want higher output units. Meanwhile, someone who rarely uses an air conditioner might prefer something with less power and a lower price tag.
Another thing to know when buying an RV air conditioner is that there are dual-purpose units available. These multifunctional units include a heat pump, so they can work as both a heater and an air conditioner. This is great because it means you use your propane stove less often, saving fuel and money.
Q: What is the cooling and heating capacity of the parking air conditioner? And how big a generator should be matched?
A: Single cooling air conditioner: The cooling capacity is usually about 1000W, and it can be matched with a 1600W generator
Heating and cooling air conditioner: The heating power is about 2200W, the cooling power is also 2300W, the cooling start time is about 10 minutes, and the cooling power is 1200W. The 2200W power of the heating and cooling air conditioner must be matched with a generator of 2600W-3000W.
Q: How to cool without a generator?
A: 1. When the RV is parked, try to choose a safe place to connect to the city’s electricity.
- If you are going to a relatively wild place, there is no way to hook up to electricity and you don’t have a generator, you can choose to use a micro fan to cool down.
Q: Can an RV air conditioner be equipped with a generator?
A: If you really need to use the air conditioner in the summer, you can consider buying a portable generator. It’s more convenient to take it with you when you need it and leave it at home when you’re not using it.

Common RV air conditioner problems:
The RV air conditioner cannot be turned on
When summer is on the road, there are many things to worry about, and an RV air conditioner that won’t turn on is high on the list. With limited airflow from open windows, you could be facing difficult or costly repairs if your roof top air conditioner fails.
If a unit will not turn on, the first thing to do is check the power source. Make sure no breakers have been tripped and all fuses are intact. You should also make sure you have enough power to actually run the air conditioner, especially if you’re sharing power between multiple appliances in your RV.
RV air conditioner cycling on and off
Having the air conditioner cycle on and off isn’t ideal, and many road warriors experience it every year. This problem is also difficult to diagnose, although you’ll want to start with the coils first.
When the coils on your rooftop air conditioner freeze up, it can cause your RV air conditioner to cycle on and off. Fortunately, this is a quick fix, as all you have to do is turn the units off until they thaw or leave them in fan mode. This can happen with dirty air filters and on humid days, depending on what temperature your air conditioner is set to.
RV Air Conditioner Leaks
Aside from RV air conditioners with power issues, the biggest problem most people face is a leaking system. We’re not talking about refrigerant either, although that can certainly cause problems. If your RV air conditioner leaks when it’s raining or drying out, it can damage the unit itself as well as everything inside the RV.
This can happen over time if the air conditioner moves or hits the roof of your RV when the unit comes loose. If this happens, you can fix the problem by tightening the screws that secure the system.
If the unit is not loose, the seal between the system and the RV may need to be replaced. This is the first line of defense against water intrusion, but rubber seals will eventually break down when exposed to the elements.
RV air conditioner does not blow cold air
Most RV owners have encountered an RV with an air conditioner that doesn’t blow cold air. While this may lead you to believe that your air conditioner is in its final stages, a thorough cleaning will likely fix the problem.
If the coils on the system are dirty (which is very common), it can cause the system to lose efficiency. Dirt and debris can get between the fins, which can be easily damaged. You can clean and straighten them with a fin comb and some elbow grease. The process will vary depending on the make and model of your air conditioner, but this video will give you a good idea of what to expect.
Tips for You: But one thing we need to understand is that for professional problems, we recommend calling professional maintenance personnel for help.
You can run an RV air conditioner all day when you’re driving or traveling. You just need to make sure you feed it a good amount of fuel to keep it chugging along.
If you do plan on running your RV air conditioner regularly, then we suggest that you take steps to increase the efficiency of it. This means making sure that the temperature is not set too low and that you are not constantly turning your air conditioner on and off. Above all, you will also want to make sure that your air conditioner is properly maintained.
