Buying Guide for Silent Air Conditioners in 2021

1. Noise Levels

The most important factor to consider when you want to purchase a quiet air conditioner is the level of noise it produces. Traditional air conditioners are noisy and can be as loud as over 60 decibels.

The good thing is some modern air conditioners are quieter at below 50 decibels. This is all you need to ensure you can sleep peacefully at night without the annoying humming sound in your ear, so choose wisely.

2. Room Size

BTU is the unit for measuring air conditioner efficiency. It stands for British Thermal Units and gives you an idea of how adequately your air conditioner would perform. What you will be looking for is a unit that can cool your room space properly.

Be careful however not to get a unit that is too big for the room as you will end up paying unnecessarily high electricity bills.

Getting a unit that is smaller than the room size will lead to poor performance and so what you need is the right unit for your room size. Generally, what you would need per estimated room size is as follows:

  • 8,000 BTU for up to 340ft2
  • 10,000 BTU for up to 450ft2
  • 12,000 BTU for up to 550ft2
  • 14,000 BTU for up to 700ft2

3. Operating Modes

It is a good deal to go for an AC unit that satisfies other needs with its features such as a dehumidifier, and fan. It’s better to get an all in one unit rather than making separate purchases for all these.

An air conditioner that also operates as a dehumidifier can remove excessive moisture in the air, so you feel comfortable and have a room free from molds even in days of high relative humidity.

You can also get heating features in AC units that will come in handy on cold days.

4. Efficiency

The higher the efficiency rating for your AC unit, the better would be its energy efficiency rating. On average, the energy efficiency rating for quietest wall air conditioners is 10.3. Look out for this in an AC unit so that you won’t have to pay so much electricity bills.

5. Ease of Maintenance

The last thing you would want is an air conditioner unit that is difficult and expensive to maintain. When making a purchase, go for the ones with removable filters that are easy to access.

By this, you can carry out cleaning and maintenance yourself without having to call for professional help.

6. Programmable Control

It’s easy to forget to put off the AC before leaving home especially when you are in a hurry, and when this repeats itself you will be faced with a huge electricity bill.

So go for an AC unit that can be programmed to turn on and off at certain times and you won’t have to worry about being forgetful anymore.

Also, some aircons are Alexa compatible and have displays for important information. Such ACs will give you information on the temperature, and energy consumption so you can monitor your use better.
