My study room gets pretty hot in summer and I planned to install a window AC. Since it is a window AC, I wanted to get an AC that is as silent as possible. I did some online research to know which window AC is most silent. I learned about quite a few ACs and came across a few options. Raju has mentioned some of those in his answer.

Top 5 Silent Window AC

Apart from the ACs mentioned in the other answer, I have added a few more names below. 

Name of AC

Noise Level

Key Features

Panasonic LN 1.5 Ton

53 dB

Copper Condenser, 1 Year Comprehensive Warranty, 5 Years Warranty on Compressor. 

LG 4 in 1 Convertible 1.5 Ton

44 dB

It comes with Auto Restart and HD Filter with Anti Virus Protection.

Panasonic XN 1.5 Ton

56 dB

It is ideal for rooms up to 170 sq. ft. and has Temperature Sensors and Conquer Heat features. 

Haier 1.5 Ton 3 Star Twin

51 dB

It comes with a quiet mode and a Low Gas Detection feature. 

Blue Star L Series 1.5 Ton 

53 dB

This AC has a Self-diagnosis and Humidity Control feature. 

These are the ACs that I found to be the quietest. From this list, I plan to purchase the LG 4 in-1 Convertible 1.5 Ton as it seems to have the lowest noise level. I hope this helps.

What is Croma AC Installation Charges?

Hello Raman, I can tell you which window AC is most silent. There are actually several options out there and you can test to see which one works the best for you. That is what I did last month while selecting an AC for our bedroom. I went with with the LG 4 in-1 convertible 1.5-ton window AC, but you can also check out the following options:


  1. Panasonic XN 1.5 Ton 4 Star AC

  2. Haier 1.5 Ton 3 Star Twin Inverter AC

  3. Panasonic LN 1.5 Ton 3 Star Inverter AC


Mr Raju has shared some parameters to check while deciding on the window AC. I agree with the ones that he has shared, but have some more to add to those. 


  1. Look for advanced noise reduction technologies. Like in LG, there is a dual inverter compressor which adjusts the cooling output and reduces noise related to the compressor cycling. 

  2. Low Sound Level: You can get ACs with sound levels as low as 44 dB, so check that. The lower the level, the quieter the AC.

  3. Fan Blades: Also have a close look at the fan blades as they are the ones that act as one of the noise contributors. Well-designed blades minimize turbulence. 


I hope this helps.

Hi, I have a window AC, that makes quite a lot of noise. I have tried getting it serviced and repaired but nothing was helpful. Thus, I decided to purchase a new one, but I wanted an AC that doesn't make much noise. I asked my friend about the most silent window AC. Here is what he told me. 

Which Are The Most Quiet Window Air Conditioner?

My friend told me about several ACs and here I am putting all the information in a table below. 

Window AC Name  Noise Level Price (Rs.)

Lloyd 1.5 Ton 4 Star 

Low

28,490

LG 1.5 Ton 5 Star DUAL Inverter

Average

37,999

Carrier 1.5 Ton 3 Star

Average

27,990

He said that these are some of the most quiet window AC, that he is aware of. He also told me that, if I want to choose other AC’s, I can follow the steps mentioned below. 

  • Check the Decibel (dB)

According to him the most quiet AC window unit will have a decibel range of 50 - 60 dB. Decibel is used to measure sound levels. So, the lower the decibel, the quieter it is.

  • Check for Variable Speed Blower Fan

AC units that make less noise come with variable-speed blowers, these operate at different speeds. This feature reduces noise and improves comfort along with cutting energy costs. 

  • Compressor Mounts

He said that a compressor is the loudest part of an AC unit and told me to look for an AC that has an insulated compressor. Insulated compressors blocks the noise coming from AC. 

This is what he told me about the most silent window AC. I hope this information will be helpful to you.
