How Cold Should an RV Air Conditioner Get? Let’s Find Out!

how cold should an rv air conditioner get

Summer is here! You’re on vacation and want to make the most of it. In this regard, the RV will be your best friend. But what about how cold should an RV air conditioner get?

A specific temperature change depends on the inside temperature of the RV. So, it is challenging to define. Air conditioners’ output should be 15-20 degrees colder than the air that they draw in from the outside. If the air temperature in your home is 75 degrees, the air flowing out of your vents should be between 55 and 60 degrees. The air should be near this area to not lead to problems.

What Factors Influence the Coolness of an AC?

The intake temperature has a significant impact on the AC unit. The temp of the AC unit will only fall if the incoming temperature falls even further. According to the manufacturing process, AC units in RVs are somewhat limited, owing to the intake mechanism.

Instead of creating air that you can cool as needed, the unit processes the cabin’s heat to a lesser extent. Thus, there will be increases dependent on the temperatures sucked into the intake. When the outside air is hot, it will harm the AC, causing it to work harder.

Why Is the RV AC Unit Not Keeping the Cool?

There are several possible reasons why your RV’s AC isn’t keeping the air cold.

  • After a few years of usage, the AC unit may be worn out. In this case, it’s not uncommon for the RV air conditioner to perform poorly.
  • The heat outdoors affects your air conditioner, preventing it from keeping up. You should install an RV AC unit or buy a bigger one that cools the RV.
  • The filters, airflow resistance, and condenser coils are dirty.

Improving Your RV’s Cooling Efficiency

Some routine maintenance on the AC unit can increase your RV’s existing cooling efficiency. I’ve curated some right here for your convenience.

  • First, remove the AC filter. The roof AC filters should be within the car beneath the airflow bezel. You can remove all the filters if needed.
  • Then, wash them in warm water. Before reinstalling, allow them to dry. If the filter is broken, it must be replaced to avoid discomfort while using it. At least once a month, check and clean your filter.
  • Check the coils with your light after the previous step. If there is dust or debris, carefully remove them with a brush or similar tool.
  • Following that, the AC cover must be removed. To do this, a screwdriver is recommended. When you arrive, make sure to gather information on the AC units so you can obtain the appropriate repair.
  • Remove any debris that has been entangled in the condenser coils with a specialized tool, such as a can of pressurized air. Make sure that the air is blown out from the inside.
  • Finally, restart your RV-AC unit to see if the cooling difficulties remain. If you are dissatisfied with the result, seek help from an RV expert. They will check and fix it until the task is done.

1. Taking Control of the Hot Temperature

Isn’t it unpleasant to be hot? This has to be taken care of right away!

Even if you are gone for the day, you may keep the air conditioner running. It’s already cool enough by the time you use it. This way, you will feel cooler and more comfortable throughout the night. You may rest assured that this technique uses very little energy.

Furthermore, you may use the air conditioner at night instead of receiving extra chilly air during the day. Because the basic concept of functioning is to circulate cold air around your RV, turning it on can conserve power. However, it is important to note that it should be turned on reasonably.

2. Make Use of the Fan on Your RV’s Air Conditioning Unit

Perhaps there are still a lot of folks who are unsure how to use it. Here are a few ideas on how to use the fan on your RV air conditioner:

First, turn on the fan and adjust the temperature to the coldest level. Then, leave the RV’s windows or doors open. This will allow the gadget to identify your proper airflow. However, this way will be employed for each period; if it is put in this manner consistently, it would burn a lot of energy and be very harmful in the long run.

Then, pay attention to how you feel. Turn on the fan and reduce the temperature when you see the air inside has cooled. If you keep it like this, the inside mechanism will be easily destroyed, and the machine will cease to function. Even the outgoing air appears to be heating up at this point. After completing the above stages, you will feel immensely at ease and calm in your area.


If you have any difficulties, you may take your RV to an RV technician for an inspection. I hope this article on how cold an RV air conditioner should get has provided you with valuable knowledge.
