the smallest portable air conditioners for rvs & tiny spaces

Summer is one of the best times to take a vacation in your RV. However, heat and humidity can be a major problem if you don’t have a good RV air conditioner.

Some rigs don’t have a rooftop air conditioning unit, but that shouldn’t stop you from traveling in the summer! Today, we’re going to talk about the smallest portable air conditioners that will cool your RV in minutes.

We’ll go over why you should use one, if portable air conditioners actually work, and share 5 of the best small portable ac units on the market.

Let’s dive in!

Why Use a Portable AC Unit In an RV?

The short and sweet answer?

You can move a small portable air conditioner into any room you’d like, rather than waiting for air to circulate through your RV.

It’s standard for new RVs to come with at least one central air conditioner installed (typically in the roof), but a lot of older models don’t have any air conditioners.

Let’s say that your rig is an older model and has a rooftop air conditioner, but it’s only in the living room. It can take hours for cool air to travel throughout your RV and when you’re dealing with the summer heat, that’s the last thing you want.

Getting a small portable air conditioner is a great way to keep certain rooms in your rig cool. If your RV doesn’t have an air conditioner and you’ll be out for a few hours, bring your portable air conditioner into the living room while you’re gone.

When you’re ready to go to bed, you can bring your portable ac into the bedroom a few minutes prior!

Can You Use Any Portable Air Conditioner in an RV?

Yes – you can! However, there are some small portable air conditioners that work better than others.

If you’re in a humid area, a vented small portable air conditioner will be your best bet. Vented air conditioners may require a hose to drain excess moisture, but most have an auto-evaporation system that can evaporate moisture into the air.

If you’re in a dry area, a ventless small portable air conditioner is for you. These small portable air conditioners use water to cool the air (and the humidity sitting in the water tank is what pumps cold air into your RV).

Because ventless portable ac units rely on humidity to work properly, being in an area that is already humid will mess with the system as it won’t be able to evaporate properly.

Do Small Portable Air Conditioners Actually Work?

Depending on the size of the room you’re trying to keep cold, yes. However, small portable air conditioners aren’t meant to cool an entire house (and depending on how big your RV is, you might have to purchase two if you want multiple rooms cold at once).

However, even the smallest portable air conditioner can cool off a room in a matter of minutes. Keep in mind that the higher the BTU is on your small air conditioner, the more heat will be ejected back into the room. Even still, a brand new portable ac unit tends to be better than the central air conditioning system that an older rig comes with.

Some portable air conditioners also double as a dehumidifier, which can improve your comfort levels while RVing (we have a few of those units in the next section)!
