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 temp 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. Let’s find out more information now.

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.

How Cold Should an RV AC Get?


So, how cold should an air conditioner blow? The air conditioner’s temperature should be 15-20 degrees cooler than the temperature 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.

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.

Tips for Making RV AC Colder?


How do I make my RV air conditioner colder? Aside from operating the AC, there are many other ways you can keep the RV cool when you’re not driving. Here are some tips for getting your roof air conditioner to perform at its best.

  • Cooling relies heavily on the filter. Check your filters regularly to ensure they are clear and unobstructed. If required, clean them with warm water mixed with a mild detergent. You should gently wipe them with a cloth and allow them to dry overnight.
  • Furthermore, inspect the airflow resistance and condenser coils on the AC unit to prevent blockages and allow the fan to blast hot air outside.
  • The machine obtains the optimum AC power at 115 volts. The device will still operate if the voltage is low, but it will not optimize the
  • Find a shaded spot to park and keep the windows closed at all times to protect the machine from the elements.
  • Use of heat equipment, such as stoves and microwave ovens should be avoided because they will cause heated air to be blown into the coach.
  • LED lights brighten everything, and they are highly recommended. One significant advantage is that they use less electricity.
  • It would be best to think about installing patio awnings and window awnings. These will give you shade, making you more comfortable.

Frequently Asked Questions 


Is it safe to leave the RV AC on all day?

Yes, it is. It makes no difference if you run your RV air conditioning equipment 24 hours a day, seven days a week. It has its thermostat, so your RV can still be turned on and off without issue. It will always be your friend as long as you have adequate power. Isn’t it worthwhile to buy one?

What size air conditioner do I need for my RV?

The size of the AC you will require is determined by the size of your setup. This is critical if you want to have the greatest experience possible. A big AC will be a good choice if you have a big vehicle. An air conditioner cools slowly and uses a lot of energy to keep your cabin cool.

In contrast, if you’re using a pickup truck or a compact trailer, a small air conditioner will be enough to keep your RV cool. You might also attempt to have two AC units for your RV and alternate between them. This is something that other RVers do to avoid atrophy.


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.
