Hi, savvy homeowners! It's Savvy Mavi here, and today, we’re tackling one of the most commonly asked questions about home cooling: What do you do when you need an air conditioner for a basement with no windows? Whether you're setting up a cool, comfortable workspace, creating a cozy home theater, or transforming your basement into an extra living area, cooling it without traditional windows or vents can seem like a challenge. But don’t worry, I’ve got you covered!
In this post, I’ll walk you through the best solutions for cooling rooms without windows, including portable AC units, air conditioners for basement windows, and even air coolers for rooms without windows. Let’s break down the options, the advantages, and how to select the right air conditioning unit for your windowless basement or room.
❄️ Understanding the Challenge: Air Conditioning for a Basement with No Windows
If you’re living in a basement or a room that doesn't have windows, cooling can be tricky. Traditional window-mounted units are not an option for obvious reasons, but that doesn’t mean you’re stuck sweltering in the summer months. There are plenty of effective solutions out there for keeping a room cool without the need for windows.
The first thing you should know is that cooling rooms with no windows requires a system that doesn’t rely on fresh air intake from outside, which is a crucial factor for many traditional air conditioners. For windowless rooms or basements, you're essentially looking at self-contained cooling units that don’t need external air sources. The good news? Many options exist, and you’re going to love what you discover.
🌬️ Best Solutions for Cooling Rooms without Windows
1. Portable AC Units for Rooms without Windows
If you're looking for an affordable and flexible option, a portable AC unit is your best bet. These self-contained units don’t require a window installation, which makes them ideal for spaces with no windows, such as basements or rooms without the proper airflow.
How Do Portable AC Units Work?
Portable AC units work by drawing in the warm air from the room, cooling it down with refrigerant, and then recirculating the cool air back into the room. One key component to these units is the exhaust hose that typically vents the hot air outside through a window or wall vent. But don’t worry—these hoses can also be adapted for use in rooms with no windows! Some portable air conditioners come with venting kits for through-wall installation, which works well for basements.
Portable AC units are available in a wide range of sizes, so you can select one based on the size of your room or basement. They are also easy to move around, making them perfect for renters or anyone who needs to cool multiple rooms in their home.
Pros of Portable AC Units:
-
Easy to move around
-
No need for window installation
-
Ideal for small-to-medium-sized rooms or basements
-
Quick and convenient setup

2. Air Conditioners for Basement Windows (or Small Basements)
While you may not have a full-sized window in your basement, you might have a small basement window that could still fit a window air conditioner. If you can manage to open the window and have a way to secure the unit, you can install a traditional window AC unit in this opening.
However, even with small windows, it’s important to know that not all air conditioners will fit. Always check the dimensions of both the air conditioner and the window before purchasing.
Best Options for Air Conditioners for Small Basement Windows:
-
Through-the-wall AC units: These are specifically designed for small spaces and can be installed through the wall, effectively replacing a window unit.
-
Compact window units: Some air conditioners are designed specifically for small or narrow windows. Just ensure that the window is wide enough for the unit’s dimensions.
Pros of Using Air Conditioners for Basement Windows:
-
Can be more energy-efficient than portable units
-
Works well for basements with small windows
-
Installation is straightforward (if you have a small window)

3. Air Coolers for Rooms Without Windows
For an alternative cooling solution, especially if you're in a space that experiences mild heat, air coolers or evaporative coolers can work wonders. These units do not rely on refrigerant, but instead, they use water to cool the air. While they are less powerful than traditional air conditioners, they are incredibly energy-efficient and work well in dry climates.
These coolers don’t need a window and can be easily placed in any room, including those without windows. They work by drawing in the air from the room, passing it over a wet filter, and then releasing the cool, moist air into the room. Air coolers also help with humidity control, which is perfect for dry spaces.
Pros of Air Coolers:
-
Energy-efficient and eco-friendly
-
No need for vents or windows
-
Great for dry climates

4. AC Units Not in the Window: How to Choose the Right Option
What if you're looking for a more permanent solution for your windowless room or basement, but don’t want to go with a portable AC unit or air cooler? In this case, ductless mini-split systems could be the ideal option. These systems consist of an outdoor condenser and one or more indoor air handlers that cool the air in the room.
Mini-split systems are perfect for homes that don’t have ducts for central air. They are quiet, energy-efficient, and provide powerful cooling without taking up valuable window space.
How Does a Mini-Split Work for Windowless Rooms?
Mini-split systems have an indoor air handler that can be mounted high on the wall, out of sight. This unit blows cool air into the room, while the outdoor unit handles the heat. The system requires a small hole in the wall for the refrigerant lines and power cables, but there’s no need for a window installation.
Benefits of Mini-Split Systems:
-
No window installation required
-
Energy-efficient and customizable
-
Quiet operation
-
Offers both heating and cooling (ideal for year-round comfort)

💡 How to Choose the Right AC Unit for Your Room
When selecting the best AC unit for a room with no windows, consider these factors:
-
Room Size: The size of the room or basement is critical. A larger room will need a more powerful unit. Use a central air conditioner calculator to determine the ideal cooling capacity.
-
Budget: Consider your budget. Portable air conditioners are affordable but may consume more energy. Ductless mini-split systems are more expensive but provide long-term savings due to their efficiency.
-
Climate: If you live in a humid area, an air cooler might not be as effective. In such cases, a portable AC or mini-split system could be a better solution.
-
Installation Options: If you can manage a small hole in the wall for a mini-split or through-wall unit, you may benefit from the permanent nature and high performance of these systems.
🔥 Final Thoughts
When you need to cool a room with no windows, there are plenty of solutions out there. Whether you opt for a portable AC unit, a mini-split system, or an air cooler, there’s an option for every need and budget. Just remember to choose wisely based on your space and your cooling needs, and you’ll be living in comfort year-round.
