Popular Portable Air Conditioners for Windowless Rooms
If you have a room with no windows that needs cooling, several types of air conditioners can be used.

A good way to cool a room with no windows is to use a portable air conditioner which can cool the space down.

Keep in mind that extending the existing HVAC system or installing a mini-split unit is usually the best long-term solution.

For those looking for a portable unit, they come in two main categories: evaporative coolers and AC units with a small hose that feeds outside.

Types of Portable Coolers for Windowless Rooms

  • Portable Evaporative Cooler
  • Evaporative coolers work when the air is dry and doesn’t have high humidity in the air.

    For this reason, they are mostly used in arid climates such as the American South West. They work from evaporation, such as when getting out of a pool on a hot day and the wind blows, cooling a person down.

    Water is fed through pads that a fan blows air through and cools the air as it passes. If you live in a dry arid climate, then an evaporative cooler will work nicely; if you live in a region that has a lot of humidity, then much less so, if at all.

  • Portable Air Conditioner
  • A portable air conditioner uses a small 5-7 inch hose to pump out hot air from a room.

    While this option still requires an opening at some location, much less so than a large window air conditioning unit. The hose can often be modified in a variety of ways to let the hot air being pumped out of a room. For example, a door can be draped with a blanket and opened slightly to let the hot air out, or the hose runs to another room that does have a window.

    Every situation will be different depending on the climate and how the room is built into a building so let’s look at some popular portable units.

There are many good units available, with some of our favorite picks below.

As always, be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.

    While this type of portable unit does need an opening at some location to pump out hot air, it will work in any climate type.

Summary
Trying to cool a room with no windows is always a challenge, and the best unit to use always changes from scenario to scenario.

If a more long-term option is needed, other types of units such as mini split units, which are air conditioners that split the components apart, use a small hole to feed in a line to run in and out hot or cold air.

Mini-split units cost more to buy and install but are long-term solutions.

Hopefully, one of the above types of units works for your situation and keeps your room cool.

    Whynter is the only good air conditioner. All of the others are a waste of money. With a portable unit, only ever buy one with 2 hoses. The 1 hose systems are garbage. The 1 hose systems give you a LOT less than the rated BTU listed on the box. For example, if you have a 1 hose system that says 10,000 BTU, it acts like its a 5 or 6000 BTU, whereas a 2 hose system would act like an 8000 or 8500 BTU. The 2nd hose makes it a lot more efficient in getting rid of the heat that the unit generates (which is sitting in the same room that you are trying to cool). In this example a non-portable window unit would give you the full 10,000 BTU’s because the HOT part of the unit is hanging outside of your house. So if you HAVE to go with a portable unit, ALWAYS at least go with a 2 hose system. Thank you.
