If your RV isn’t getting as cold as it once did, you might need an RV AC recharge. Can RV air conditioners be recharged? Just like you can add refrigerant to your home air conditioning and your automobile, it’s also possible to learn how to recharge an RV AC unit.
In this guide, we look closer at recharging RV air conditioning systems.
How To Tell That My RV Air Conditioner Needs Recharging?
If the RV air filters are dirty and need cleaning, they can present the same symptoms as if the RV needed to be recharged. Dust and dirt can stop air from flowing through the filters, causing a drastic reduction in cooling.
If the air conditioning system isn’t circulating correctly, it can freeze up some of the vital components. To run normally again, the parts must first be defrosted. This problem will look similar to when the air conditioning needs to be recharged.
The RV air conditioning system contains several hoses and parts that can leak when they become worn out. If there is a crack or leak in the system, you will think it needs a recharge, but this won’t solve the problem because the refrigerant will just leak back out. There are even times when you need to replace the AC hose to solve this problem.
AC Blowing Warm Air
If the other problems aren’t present and the RV air conditioning is not blowing cold air, you might only need to perform a recharge. If you want to fix the problem, you just need to know how to recharge the RV AC.
What Refrigerant Is Used In RV AC Units?
How To Recharge RV Air Conditioner (Freon Guide)
Do RV air conditioners need to be recharged? There may be a time when you need to add more Freon to the air conditioning system to keep it running cold. Before you learn how to charge an RV air conditioner, gather these supplies.
- Refrigerant gauge
- Line tap
- Household tools
The most important supply needed is refrigerant. However, you need to make sure you get the right kind before you try to figure out how to charge an RV AC unit. This information can be found in the service manual, or you can ask your local RV dealer.
Learning how to charge an RV roof AC system requires you to follow these instructions:
- Turn off any power, like a generator going to the air conditioner of your RV or car. You want to switch off the breaker supplying power to the AC system.
- Remove the plastic housing over the air conditioner. The AC cover is attached to the roof in various ways, depending on the brand. Some manufacturers use screws, and others rely on clips. You should be able to remove it with generic household tools; just use caution so you don’t break anything.
- With your refrigerant scale or gauge, you can tell what level the AC is at.
- If the refrigerant needs to be recharged, install it into the system slowly until it reaches the desired level.
- Replace the air conditioner cover.
- Turn on the breakers and plug your power back in.
- Test the air conditioning system to ensure you followed the steps showing how to recharge a camper AC.
If you aren’t sure what you are doing, it’s best to hire a professional for the AC service. The cost to repair broken parts isn’t worth the few dollars you will save doing it yourself.
Can Dometic RV Air Conditioners be Recharged?
You can still perform a Dometic RV Air conditioner recharge by yourself. While Dometic makes RV rooftop air conditioners, you may also have one of the split units or one found under the bench. With either of these designs, the overall method remains the same.
Make sure you read the owner’s manual from the manufacturer. In this guide, you should find all of the steps. Most importantly, you want to make sure all power is off to the air conditioner and that you have the appropriate Freon type before beginning.
People Also Ask (FAQ)
How much Freon does an RV take?
It depends on the type of air conditioner you have and how low the system is. Use your refrigerant gauges to determine how much Freon you need to add for a cooler environment.
How long does Freon last on RV AC?
Unless there is a leak in the system, you shouldn’t go through much Freon. However, just like with a car, it’s wise to have air conditioning service performed once a year before it gets hot.
How do I know what kind of Freon my air conditioner uses?
The majority of new air conditioners rely on R-410A Freon. This form has replaced the older R-22 Freon. Read the service manual on the air conditioner to determine what to buy.
How cold should an RV get with AC running?
During a normal day, your RV should be able to achieve indoor temperatures that are 20 degrees Fahrenheit lower than the outdoor temperatures. If not, you might need to recharge the AC.
How much does it cost to recharge the RV air conditioner in a shop?
The average cost to recharge an RV AC would be around $250 or more. If any parts are needed to repair the air conditioning system, the price could be much higher.
You can perform an RV AC Freon charge on your own with a bit of experience. If you have the right tools, it makes sense to do this basic task on your own.
