Why Portable ACs Are Best For Dorm Rooms

Let’s face it; college dorms are small. That’s not to say that they need to be uncomfortable. Believe it or not, many college dorm rooms do not have central AC. If you go to college in a warmer climate, like Florida, then they might have AC, but students will have no control over it.

If you go to college in New England, then you will not likely have central AC. Portable AC units are best for dorms because they are small, inexpensive, and you can control the temperature on your own. The average dorm room size is 180 square feet for two students.

Choosing Portable Air Conditioners For Dorms

Coverage Area

Dorm rooms can range in size from 120 to 250 square feet for two students. You’re lucky if you end up in a bigger one. Portable AC units range in coverage area from 100 to 400 square feet. You won’t have a problem finding a unit that is suitable for your room size. It might be a good idea to get a unit that is slightly larger than your room to ensure it cools effectively on hot days.

Energy Efficiency Rating (EER)

The portable AC units on our list come with an EER rating that lets you know how much energy they use. Less power consumption means less running up the bill in your dorm room. It also allows you to use the AC less often since it’s energy-efficient enough to cool the room down quickly.

Noise Levels (dBA)

Besides trying to get enough sleep for the day of classes ahead, you’ll also be studying in your dorm room. You’ll need it to be quiet at all times. You should choose a portable AC unit that operates at lower decibels. Most units have a noise level of 49 to 57 decibels.

Air Filters

Dorm rooms can become stuffy due to the enclosed space. They can also smell, and the air quality could be less than ideal. It might be a good idea to get a portable AC unit that comes with an air filter. Some machines have a HEPA, carbon, or pre-filter that can be washed or changed.


All of the dorm room AC units on our list are portable due to their size and weight. The most portable units include rolling casters on the base so that you can roll it around the room. Some units also include carrying handles. Another good option is to invest in a tabletop AC unit that you can sit on your computer desk.

Performance Features
    • Heat Mode
      If you go to school in a cold climate, it might be best to get an AC unit with a heating mode. They can be more expensive, but without central heat, you might get cold.
    • Sleep Mode
      This mode is ideal for running the unit at night. It will dim the lights on the machine and turn the fan speed down. It will help you get adequate sleep.
    • Fan Speeds
      You want to be able to change the fan speed on your AC unit. It will help you regulate temperature and control the noise level.
    • Auto Setting
      This setting is great for setting and forgetting your AC unit. You set the desired temperature, and it regulates the environment according to that temperature. It automatically adjusts fan speed and cooling.
    • Remote Control
      If you’re in the middle of working on a term paper, then a remote control is useful, so you don’t have to get up.
Installation Requirements/Ease of Setup

Since you have limited space and resources, you should buy a unit that is easy to set up. You should check if your system will need a drainage area. If so, then the pipe will need to be out the window. You should also check if it requires any tools to assemble before you buy it.


All of the units that we reviewed come with a manufacturer’s warranty. They range in duration from 90 days to 1 year. Most of these warranties cover manufacturer’s defects and other malfunctions for a certain length of time. They don’t cover misuse and normal wear and tear. Make sure that you activate your warranty upon receiving your device.


We have included a range of portable AC units to fit every budget. Some of the more expensive models come with extra features and cover more area. Some of the budget-friendly options will suit the needs of most college students without all the extra options. We recommend sticking to your budget and finding the right model for you.

Noise Output49 dBA
Voltage110 V
Weight65 lbs
Dimensions11.8 x 15.4 x 30.4 inches

Dorm rooms can be loud due to their size and the number of people living in them. When you’re studying, the last thing you need is a lot of noise. We chose theTOSOT 8,000 BTU as the best quiet dorm room air conditioner. It runs at about 49 decibels, which is a little less than a household refrigerator.

It comes with an innovative X-Fan technology that keeps the fan spinning at slow and silent speeds to dry out the machine’s interior.

6. Global Air

Best Smart Dorm Room Air Conditioner
Noise Output55 dBA
Voltage115 V
Weight62 lbs
Dimensions17 x 13 x 31.3 inches
Coverage Area300 sq ft

For all the technology and engineering majors out there, this might be the model for you. We chose Global Air as the best smart dorm room air conditioner due to its auto-adjusting temperature system. Basically, it reads the room temperature and adjusts to make you more comfortable.

This model comes with a self-evaporating system that does not require a water tank. The water condensation is recycled back through a cooling condenser, which is another reason we think it is the smartest unit on the market. This dramatically improves the efficiency of the machine. It comes with over-cold protection that will shut off the machine before the condenser freezes over.

This unit must be vented outside like the other units that we reviewed. We like the smart features of this unit.

Determining The Right Size AC For Your Dorm Room

Now that you’ve seen all of your options, you need to understand what size portable AC unit you’ll need for your new dorm room digs. If you haven’t moved in yet, you can check your university’s website to find information on the size of the residence halls.

Some of the smallest dorm rooms are around 96 square feet. The medium-sized rooms are around 180 to 200 square feet. Anything above 200 square feet is considered large. You should check the size of your room to determine the right size AC unit. The room size is directly related to the AC size that you need.

If you have a room under 150 square feet, then most of the models on our list will do the trick. If you have a large dorm room, then you may need to opt for a model that covers more square feet.

Setting Up Portable AC Units In A Dorm Room

Now that you’ve picked the right size and ideal portable AC unit for your new room, you need to know how to install it without damaging anything in the dorm room. Follow our simple steps below to install and vent your new unit.

  1. Measure the width of your window with a tape measure.
  2. Apply foam weatherstrip to the window frame to ensure you have a good seal.
  3. Adjust the window bracket included with your portable AC unit kit.
  4. Place the window bracket into the opening and close the window.
  5. Secure the bracket if necessary. Your kit might include some screws and L-shaped brackets to hold it into place.
  6. Connect the vent hose to the AC unit and to the hole in the window bracket that you just installed.
  7. Plug in the portable AC unit near the window and turn it on.

Maintaining Optimal Air Quality In Dorm Rooms

Dorm rooms can get stuffy since there are usually 2 people enclosed in a tiny space with a very small window. Since you’re often on campus all day and in class, you pick up a lot of germs. Many students walk in and out of their dorm rooms multiple times a day.

The best way to help improve air quality is to invest in one of the portable AC units above. Many of them are also dehumidifiers, which can reduce odor and moisture in the air. Most units also include a washable filter that traps allergens and dust. Another great way to improve air quality is to invest in some house plants or an air purifier.

People Also Ask (FAQs)

Can I use a portable AC in a dorm room without windows?
