Air conditioners are often necessary for dorm rooms, especially during the hot summer months. Unfortunately, traditional air conditioners use a great deal of energy and require window space for installation. Fortunately, there are a number of compact and energy-efficient air conditioning options available for those with limited space and wanting to reduce their overall energy consumption.

This guide will explore the different types of air conditioners specifically designed for dorm rooms, as well as highlight some compact and eco-friendly models on the market in 2020. We will discuss factors such as size, cooling capacity, features, ease of installation and cost to help you make an informed decision when choosing an air conditioning system for your dorm room.

Factors to Consider When Choosing an Air Conditioner for Dorm Rooms

To choose the best air conditioner for your dorm room, it’s important to consider factors like size and energy efficiency. The size of your air conditioner should be based on the amount of space you have in your dorm room. Small window units can provide cooling for smaller dorm rooms, but larger rooms require bigger units. You should also compare the energy-efficiency ratings provided by manufacturers to ensure you’re getting the most efficient model possible.

Some additional features that may come with different models include:

  • Remote control operation: This allows you to control all settings from a distance.
  • Programmable timer: Many models offer a programmable timer so you can set up specific cooling times that fit in with your class schedule, or just cut back when you don’t need cooling as much.
  • Automatic restart mode: If there is an unexpected power outage, many modern models will automatically restart when power is restored.
  • Sleep mode: Many AC models come with a sleep mode that helps reduce noise as well as energy consumption during the night hours.

Size of the dorm room

When choosing an air conditioner for your dorm room, evaluating the size of the room is one of the most important steps. The size of your dorm room will help determine which type of air conditioning system will be best suited to meet your needs. It is important to choose a system that is not too big or too small, as an oversized system will operate inefficiently while a unit that is too small won’t be able to cool your space adequately. If possible, consult with a professional HVAC contractor who can recommend a model that works for you.

Before choosing an air conditioning unit for your dorm room, take measurements of the space and take into consideration factors such as number of windows and furniture placement. Here are some examples:

-For very small dorm rooms (up to 150 square feet): window-mounted ACs are usually best choice since they can fit in most standard-sized windows; they are both compact and energy efficient and often have a cooling capacity up to 10,000 BTU/h.

-For larger dorm rooms (150 – 250 square feet): portable AC units can be used. Portable AC units offer more flexibility than window-mounted systems because they can be moved from place to place; their cooling capacity starts at around 10,000 BTU/h and goes up to around 14,000 BTU/h or higher for extra-large spaces.

BTU (British Thermal Unit) capacity

The British Thermal Unit, or BTU is an international measure of energy efficiency. It is used to rate the cooling capacity of air conditioners and other cooling systems. The higher the BTU rating, the more powerful the appliance. Most dorm rooms will require an air conditioner with a capacity between 5,000 and 7,500 BTUs in order to cool the room effectively.

When selecting your dorm room air conditioner, make sure that it has enough power to effectively cool your room without using too much electricity. It’s also important to note that different models may have different energy efficiency ratings based on their design and size. So make sure to check the energy efficiency star rating for each model before making a purchase. This will help you determine which model is best for your needs without unnecessarily driving up your power bills!

Energy efficiency

When shopping for an air conditioner intended for use in a dorm room, energy efficiency is an important factor to consider. Energy efficiency vastly reduces electricity bills—in fact, it can reduce such bills by as much as 50%. With limited resources available for college students, minimizing monthly costs is essential. We’ve listed some of the best energy-efficient air conditioners you may want to look into:

Window Air Conditioners: Window ACs are popular and affordable choices. When shopping for one of these models, look into which type has a programmable timer. This minor difference allows you to save on energy costs by having the unit shut off when it’s not needed while still providing cooling when temperatures rise to uncomfortable levels. Higher-end models with inverter technology can be even more efficient and cost-effective, but they come with a hefty price tag attached.

Portable Air Conditioners: For those living in dorm rooms without access to an open window or sliding balcony door, portable ACs provide an easy solution for cooling down the space. Like window units, these come in different sizes depending on how large of an area you’ll need cooled off. Some even have intelligent sensors that monitor a room’s temperature and automatically adjust fan speed levels accordingly so you don’t have to fiddle with settings yourself! However, keep in mind that the exhaust hose must be vented through a window or sliding balcony door — if you don’t have either option available this won’t be feasible.

Heat Pumps: Heat pumps are perfect if you want something that cools and warms since this type of AC serves both purposes! They draw less power than other alternatives and make use of reverse cycles that move air from indoors out and from outside in depending on time of year or current temperature needs within your room/space itself – meaning no noise from starting/stopping several times throughout its cycle life either! Additionally this style will likely work more efficiently over time than traditional alternatives because their efficiency ratings are consistently higher due to their design process taking into account environmental elements much more closely than some competitors would do otherwise making them one solid choice for future planning if budget allows!

Noise level

Noise level is an important factor to consider when purchasing an air conditioner for a dorm room. For some people, it is difficult or even impossible to concentrate and study when there is too much noise in their environment. Fortunately, modern air conditioners are designed to be much quieter than older models.

When shopping around, look for air conditioner units that have a low decibel (dB) rating, because this will indicate lower noise levels. Anything in the 40 to 50 dB range is usually considered relatively quiet; however, some models may even boast ratings as low as 35 dB. For reference, a typical conversation between two people has an average sound level of around 60 dB.


When choosing an air conditioner for a dorm room, it is important to remember the size restrictions and limited space in these rooms. A portable unit is a good choice, as these models can usually fit on most window sills. As an added bonus, portability allows for occasional transfers to other locations or rooms if needed. For times when you might be relocating, investing in a portable unit allows for convenience and easy transport to different places without sacrificing energy-efficiency or quality of cooling.

The majority of the portable models available offer quiet operation in comparison to other air conditioner types with multiple fan speeds and are relatively lightweight for easy moving and storage. Many are designed with an extra-long cord that makes it easy to access an outlet from any location in the room. With convenience features such as internal dehumidification systems, digital LED displays and removable mesh filters, choosing a portable option can ensure maximum comfort and peace of mind as you enjoy your stay!

 Maintenance Tips for Air Conditioners in Dorm Rooms

Air conditioners installed in dorm rooms are subject to the same rules of maintenance as those installed in any other area of a home. While there may be additional considerations when dealing with small and compact units, the basics remain the same. Regular cleaning and maintenance will help keep your unit running smoothly and efficiently while also reducing the potential for costly repairs down the road. Follow these tips to ensure that your air conditioner is able to provide you with cool air whenever you need it.

  1. Verify Your Warranty: Check with the manufacturer to make sure you are familiar with any warranty coverage for your unit and how to file a claim if necessary.
  2. Schedule Regular Maintenance Visits: Have your dorm room’s air conditioner serviced at least once a year by a qualified technician, who can check for frayed wires, replace worn parts and make sure that everything is running properly. Keep up with routine cleanings; dirty filters can reduce energy efficiency significantly, leading to longer-than-necessary cooling cycles and increased energy bills over time.
  3. Clean Out Filter Grilles and Vents: Check filter grilles periodically for dust or dirt buildup, then vacuum them out or use compressed air or an attachment on a vacuum cleaner hose to loosen stubborn particles before they build up enough to impede airflow into the unit. Make sure all vents in your room are open and unobstructed – closed vents can lead to poor circulation of cool air throughout a room, resulting in hot spots or inadequate cooling overall.
  4. Monitor Temperature Settings: From time to time, double check that you have set temperatures correctly by checking thermometers near areas where cooler air should be present – this is especially important when first turning on an AC unit after long periods without operation during colder seasons! Avoid running it too low — keeping temperatures below 78 degrees will not provide any extra cooling benefit but will simply increase energy costs needlessly!

Cleaning the air filter

The air filter of your air conditioner is the key component to ensuring its upkeep and efficiency. To ensure that you keep your air conditioner working at peak performance, it is essential to clean or replace the air filter regularly. Depending on environmental conditions, clean the air filter in your air conditioner unit every 3-4 weeks.

This can be done by going outside the unit and using a vacuum with a hose attachment to remove dirt and cobwebs from around the filter. If needed, lightly spray down any caked-on dirt with a mixture of mild detergent and lukewarm water before vacuuming it off or replacing it.

Check with your manufacturer if they suggest any specific guidelines for cleaning or replacing the air filter in their units.

Checking for leaks

Before investing in a new air conditioner for your dorm room, it’s important to check for leaks. Look for any gaps around windows and doors, as well as lofts and skylights. Check the ducts to ensure that they are all properly sealed. If you find any leaks, seal them using caulk or insulation to prevent air from escaping or entering your dorm room, reducing your cool air bill by as much as 10%.

Additionally, take a look at the insulation inside of your walls and make sure that it is up-to-date and not clogged with dust. Poor insulation can mean steep energy bills throughout the summer months due to wasted energy escaping through cracks.

Keeping the area around the air conditioner clean

In order for your energy efficient AC unit to work most efficiently, it’s important to keep the area around it clean. Without regular cleaning, dust, dirt and debris can accumulate, reducing your air conditioner’s performance and efficiency. Additionally, the vents in the air conditioner need to remain clear so that air is able to move through them unrestricted.

Take a vacuum cleaner with an appropriate attachment and brush or cloth every couple of weeks to clean around your unit and any vents as part of your regular maintenance. You may also wish to use window cleaner in addition to a soft cloth; be sure not to use anything abrasive or that will scratch or damage the air conditioner.

After you’ve finished cleaning, be sure the air filter is changed regularly following manufacturer instructions found in the user manual.

Regular servicing

Regular servicing of air conditioners is essential to keep them running at their best. Doing maintenance regularly on your air conditioner results in improved efficiency, optimal performance and fewer breakdowns. Plus, it extends the life of your unit – helping you get the most from your purchase.

Steps to be taken in regular servicing include clearing all debris, cleaning the filter and coils, checking for any signs of wear and tear, lubricating moving parts, flushing condensate drains, checking indoor temperature settings, refilling coolant if necessary, making sure electrical contacts are secure, and resetting the overall system if needed. You can also test a cooling system by turning it on and running it until a steady temperature is reached throughout the room. It’s important to check each part carefully during servicing because a single issue can reduce energy efficiency or cause breakdowns.

The best way to keep an AC unit healthy is with regular preventive maintenance from an experienced technician who specializes in HVAC repairs.


In conclusion, dorm rooms often require special consideration when choosing an air conditioner. It is essential to select a unit that is both space-efficient and energy-efficient. Fortunately, there are a wide variety of air conditioners suitable for the unique demands of dorms and small bedrooms, ranging from window units that can easily be installed in most standard-sized windows to smaller, portable models offering greater flexibility.

No matter which option you choose, an air conditioner can help to make your dorm room more comfortable and enjoyable during the summer months. Be sure to read reviews and compare models before making your decision to ensure that you purchase the best possible unit for your needs.
