Maintaining the perfect temperature level in your bedroom can be a challenge. When the hot summer months kick in, the heat can be almost unbearable if you don’t have a cooling system in place, interfering with the quality of your sleep. That’s why you need the best air conditioner for bedroom.

Most air conditioners have one job (keep the room cool), but finding one that suits your bedroom isn’t an easy task. You have to consider a lot of factors, including the size of the room, the number of people who will occupy the space, energy efficiency, and maintenance.

Once you have the answers to those questions, then it’s easy to find exactly what you need. But again, there are numerous AC brands and models on the market.

However, you don’t have to spend a lot of time trying to find the best air conditioner for small bedroom. Here, you’ll find both portable and window air conditioners for bedrooms. If your room doesn’t have a window, I’d encourage you to check the best air conditioners for rooms without windows.

Do you need an AC for your Bedroom?

Absolutely. Like anywhere in the home, the bedroom becomes sweaty and hot during the peak summer weather. Even the biggest fans of the sunny weather will want a way out of these conditions. When used alongside a fan, the air conditioner can help drive out the heat and dehumidify the place to more comfortable levels. 

Benefits of Sleeping with Air Conditioner at Night

There are multiple benefits of sleeping with an air conditioner at night. The following are the most apparent advantages;

  • Better sleep: Studies show that humans sleep better in temperatures around 65˚F. Considering that average daily temperatures range between 74-76˚F, you can see that we sleep better in colder conditions. An air conditioner can help you achieve the required lower temperatures. 
  • Less sweating: If you sweat a lot at night, you could undoubtedly do with air conditioning. The need is even greater in the peak summer months when night temperatures rise beyond 100˚F. Air conditioning can reduce sweating by blowing cool air around you. 
  • Reduces risk of dehydration: One of the main challenges associated with excessive sweating, especially at night when you may not be awake to rehydrate as necessary, is dehydration. You may lose so much water that it affects your internal organs. Dehydration may also affect the skin. Proper air conditioning reduces the risk of dehydration. 
  • Prevent heatstroke: Though rare, heatstroke is a severe condition and is considered a medical emergency. It often results from milder heat-related illnesses, such as heat cramps, heat syncope, and heat exhaustion. Primarily, it’s caused by extended exposure to high temperatures. You can reduce the risk of heatstroke by investing in a bedroom air conditioner. 

Risks of Using an Air Conditioner in your Bedroom at Night

Despite the many benefits, however, sleeping with an air conditioner in your bedroom at night comes with a few challenges that you must keep in mind. These include;

  • Over dehumidification: Remember that as well as heat, air conditioners also remove moisture. This isn’t usually a problem if you’re using the right size air conditioner. However, it’s something to keep in mind. 
  • Noise challenges: Though bedroom air conditioners are designed to be extremely quiet, the vibration of the compressor shell, electric motor vibration, and the noise coming from the rotating fan are ever-present concerns. 

Factors to Consider when Choosing an Air Conditioner for the Bedroom

Everyone will ultimately pick a bedroom air conditioner based on personal preferences and the price. However, it’s vital to consider a few factors, especially the following;

best portable air conditioner for bedroom

Understand AC Types – What Type of Air Conditioner is Best for a Bedroom?

There are many different ways to classify air conditioners. However, the best-known air conditioner types are central, ductless mini splits, window air conditioners, portable air conditioners, and through-the-wall air conditioners

For bedroom applications, window, mi split models, and portable air conditioners are the best options. Mini-split models are the best choice for energy efficiency, window models are best when considering both efficiency and price, and portable models are great for their mobility and the absence of the often-complex installation process. 

Sizing the Air Conditioner: How many BTUs do you need? What size air conditioner do I need for a bedroom?

The rule of thumb is 20 BTUs for every square foot. Therefore, for the average 350-400 square-foot bedroom, you need about 7,000 to 8,000 BTU air conditioners

However, the actual requirement may vary depending on the ceiling height, exposure to direct sunlight, and insulation quality. Generally, add 10% more BTUs/foot for ceilings above 8.0 feet and bedrooms exposed to direct sunlight. For rooms in shady areas, reduce the BTU by 10%. For insulation, it’s best to call a professional to measure the room’s R-Value. 

Where Should You Install an Air Conditioner in the Bedroom?

The best position for wall-installed air handlers (mini split air conditioners) is directly above the bed so that it directs airflow right above you. Window air conditioners would go in the window, while in-wall models are best installed on exterior walls. 

For portable air conditioners, place it along the opposite wall with the air louvers facing the bed. This allows for maximum flow of air in the room without creating too much cold around you. It should be at least three feet away from the bed and ideally placed along the wall to prevent dangerous cluttering. 

Other Considerations When Buying an AC for your Bedroom

Other factors to consider when shopping for an air conditioner for the bedroom include the noise rating, energy efficiency, ease of control, additional features, and warranty.

The noise rating should be very low, the energy efficiency, measured in EER or SEER, should be as high as possible, and the unit must be very easy to control. Remote and app control, where available, are a big bonus. Concerning functions, a timer and programmable thermostat would go a long way. Some air conditioners even have apps, which further increase convenience. Finally, you want at least a five-year warranty on the compressor unit.
