Look For These Features In The Quietest Portable Air Conditioner 

Portable air conditioners are amazing. You don’t need to spend a lot of money on it yet you get the same level of a cool breeze as you would get from a central air conditioner. They are also compact and you can easily take them to places. While there are so many positive sides, there are a few not-too-outstanding features too. The most annoying feature is the noise that they create. 

However, not all portable air conditioners are noisy and you can easily avoid a noisy air conditioner by looking for these features. So, follow this guide and I promise you that you will never come across a noisy air conditioner again. 

Low Noise Level 

You can find out how noisy the air conditioner is just by looking at its noise level. Each portable air conditioner comes with its noise level attached to the packaging. That being said, the portable air conditioner’s noise level is mostly within the range of 50- 60 decibels. If you want a quiet portable air conditioner, then make sure the noise level is under 55 decibels. That way, you can tolerate the faint noise without being irritated.

Dual Motor System 

Usually, portable air conditioners have two types of motor systems. Single motor air conditioners and dual motor air conditioners. Single-motor air conditioners typically make more noise than a single motor one. So, you should choose a dual motor system air conditioner since they are significantly quiet. You can see if the air conditioner has an insulated compressor. Insulated compressor plays a huge role in reducing any noise. 

Fan Speed

You can easily find out if the air conditioner has multiple fan speeds. Brands mention that in their product description. So, when you have the option to choose from multiple fan speeds, you can easily go for an airflow that makes the least amount of noise


Btu rating is basically the cooling power of your air conditioner. While it is important to have an AC with BTU compatible with your space. However, you get an AC of a little more capacity. Now this has to do something with the noise. If your AC has more BTU, then you can operate it at a lower BTU. By doing this, you can lower the noise level. So, what I’m saying is if you can operate your AC at low BTU, then it will also produce less noise. 

What Makes Portable Air Conditioners Noisy 

Portable air conditioners are absolute blessings during a hot summer day. There are a lot of people living in apartment buildings without a central air conditioner. While window ACs are great but they have their own shortcomings too. In these stated situations, portable air conditioners work the best. 

Like they say, there is no gain without pain. Portable air conditioners will also cause you a little pain and that is the noise. It is no secret that portable air conditioners are noisy and if you ask me if there are any silent portable air conditioners, then I’m sorry to disappoint but there are no such things as a silent portable air conditioner. 

Now, let’s find out where that noise is coming from. There is one particular reason, and that is the compressor being inside. Since the compressor is inside instead of outside, it makes the noise. As simple as that. 

Make a Portable Air Conditioner Quieter 

We have established the fact that portable air conditioners are noisy and we have also explained previously the cause of noise. Now let’s see if we can do something about the noise. So, there are a few ways you can make your portable air conditioners. 

Like I said, there are some ways to reduce the noise. You can’t totally eliminate the noise but you can see if the following tricks work with you. 

  • Run your air conditioner in a lower setting. 
  • Clean the reusable air filters or replace them every three months. 
  • Thoroughly clean the room to avoid any dust getting stuck in the AC
  • Place the air conditioner at a decent distance 
  • Purchase a portable air conditioner with a lower noise level
