How to Choose Quietest Window Air Conditioners for Bedroom

However, you have might never be thought about that but we spend in bedroom plenty of our time. And find the perfect quiet AC machine that meets all of our requirements is crucial. But what are the most important aspects we should take into consideration before choosing an appliance?

Keep reading and check out what the aspects are and how can positively and negatively affect our comfort in a bedroom or operating of the machine.

Noise Level

The noise level of a window air conditioner is very often overlooked. People tend to underestimate this important aspect. It leads to troubles with sleeping or impossibility to sleep while the unit is operating. And to be honest, we do not buy the AC unit to let it switched off. We need the appliance works well and we can rely on it.

In general, we rate the noise according to a value defined in unit decibels as known as dB. The manufacturers express the noise as a part of a window air conditioner specification. Therefore, it’s easy to find out how many decibels the unit produces on low, mid, and high. But how many decibels we should or shouldn’t accept? That’s a good question.

If you have or used to have another window AC unit you can rate if your machine is or was noisy or pretty quiet. But if you don’t know the noise in decibels you can’t compare the old unit with some new ones.

For your better overview, there are some examples of values in decibels:

  • 50 dB – It is a sound like a normal talk between two people or a sound of light rain.
  • 55 dB – You can imagine this sound as a running TV.
  • 60 dB – This sound is like a dishwasher when you’re sitting next to it or a bit louder talk between two persons.

As you could see the noises aren’t so bad. And maybe lots of you would say it’s acceptable even if the noise level of an air conditioner is 60 dB. Unfortunately, it’s not so easy.

When we’re planning to buy a new AC unit for a bedroom we should take into consideration what’s the purpose of this room. We sleep there, of course. We also talk with our partner in a bed. Many of us watch TV or a movie before going to bed. And somebody like me loves to read a book before the dreams come. It means we desire to obtain a reliable and quiet machine that won’t interrupt the calm phase before the night.

I rate every unit producing a noise level up to 55 dB as a convenient window air conditioner for bedroom. A machine like that gives you comfort and your health doesn’t suffer from unbearable noisy operating. If it’s possible it’s better for you to find an appliance having the operating noise under a value of 55 dB.

Heating Function

We are talking about a reliable air conditioner for a bedroom and that’s why we can’t omit to mention a heating function. You can read the best window air conditioners with heating reviews. Not all of the machines available on the market offer this function. I think the heating is a brilliant thing when your device is installed in a bedroom. The heat helps us to fall asleep and it also helps us to sleep calmly.

Many experts tell you how important is to warm up in a bed before sleeping. And if you have an issue with falling asleep they recommend taking thick socks and warm gloves. This trick improves blood circulation and artificially simulates the process of sleeping.

If you prefer not to wear socks and gloves for sleeping it’s better to start to think about a source of supplemental heating. Yes, I’m talking about the supplemental heating and not the heating itself. Why?

You have maybe noticed that if the unit claims to have some level of cooling capacity in BTU it also has a heating capacity in BTU. But the two values aren’t the same numbers. First of all, it’s a sign the heating is only supplemental.

It means you need the primary source of heat and the window AC unit only helps you to increase the temperature or keep the desired temperature. The heating capacity in BTU is usually weaker than the cooling capacity in BTU and you should definitely keep it in mind specifically when you are searching for the best window air conditioners for large rooms.

The principle of how the air conditioner works as a heater is the same as working as a cooler. It’s a principle of a heat pump. In hot months the refrigeration cycle uses hot air and produces the cold one. During winter the cycle is reversed. The cold air from the room is sucked inside and the unit blows the hot air back to the bedroom.

The electricity used by the unit is used only to power the compressor and the fans (inner parts of AC unit) but not to create heat actually. Therefore, less energy is needed and you won’t pay high bills during winter.

Remote Control

The remote control is a must-have for every window air conditioner in a bedroom. I would never purchase an appliance that doesn’t have a remote control. When I’m in a bedroom I want to chill out, read a book in a bed, or watch a movie. For me, it’s impossible to get up and go closer to the AC machine and change the settings or turn it off.

Of course, there are some differences among all types of remote controls. The best option is to choose full-function remote control. Trust me, it would be useless not to have for example heating function on the remote control. And to be honest, nobody wants to leave a bed in order to switch off the unit.

Wifi Connection

From my point of view, the wifi connection is a very pleasant function and you will appreciate it wherever you are. Thanks to the wifi feature you can easily connect your smartphone with the window air conditioner through your home network. Check out my best smart window air conditioners with wifi in review and buying guide.

This function allows you to operate the unit and change settings, speed of a fan, temperature, or program a timer before you come home sooner or later than usual. There won’t be any unpleasant feeling of too hot air. You can set everything while sitting on a dinner with your partner and enjoying romantic moments.

The Bottom Line

We spend lots of free time chilling out, reading books, sleeping, watching movies, and enjoy moments with somebody we love in a bedroom. Therefore, we should pay attention to how to choose an efficient and quietest window air conditioner for a bedroom.

The parameters that are usually taken into consideration for your choice are different here. The reason is your bedroom is an oasis of peace, fresh air, and pleasant feelings. It would be very naive to choose only according to cooling capacity in BTU or energy efficiency. There are more and more aspects affecting your comfort during sleeping or having a rest after a very demanding day.

This article gave you a better overview of how to choose the window air conditioner for every sleeping space and help you better understand some terms you can meet on the labels of the technical specification of the cooling machines.
