Quietest Thru the Wall Air Conditioner
Quietest thru the wall air conditioner and window air conditioners are similar in design. However, some differences make users choose one over the other.
As the name suggests, window AC’s are installed on the windows. But by design, air conditioners aren’t designed to fit any window design. Therefore, further customization has to be done to prevent seepage.
Window AC’s vent heat from the back and the sides. However, the wall units only vent heat from the back, hence helping significantly lower the amount of air that makes its way into your room.

Quietest Wall Air Conditioner Buying Guide
Thinking of investing in a quiet wall mounted AC unit, we’d highly recommend considering the following essential factors to help you in your buying decision.
The first and most important factor, in this case, is the noise level. Traditional air conditioners are noisy. They are rated 60 decibels. Fortunately, modern types are rated below 50decibels which makes them quieter than conversational speech. (Source)
This factor could be the thin line between a night of quiet sleep or nightmares from your loud AC. If you’re considering investing in a unit for your bedroom or study, consider the Keystone or Kenmore AC’s above.
The efficiency of air conditioners is measured in BTU, which means British Thermal Units. Make sure you invest in a sturdy unit that’s going to cool down the space where you’ll install it expertly.
Also, watch out not to buy a unit that’s too big for your house. You don’t want to buy a 10000 BTU unit if you intend to cool a 150sq. Ft room. This will spike your electricity bills.
On the other end, investing in a 5000BTU unit for your 750sqft room means that your room won’t be adequately cooled down.
Roughly speaking, a 7000BTU unit will cool a room up to 300sqft while a 5000 BTU AC is ideal for rooms up to 150sqft.
It’d be better to invest in a conditioner that features customizable settings and different modes.
Some units feature built-in dehumidifiers and other adjustable fan speeds. Dehumidifiers help get rid of moisture out of the air to keep your room free from molds.
The more efficient your air conditioner is, the higher the energy efficient rating it will be. The average energy-efficient rating for most wall AC units is 10.3 and the best units have a rating of up to 10.7
Other important features to keep tabs on include timer, digital temperature control, and filters.
Because it can be quite expensive running different electrical appliances at home, it’d be wise choosing an air conditioner with different programmable settings. This will enable you to program it and use it without worrying about forgetting to switch it off.
Most AC units feature remote, Wi-Fi, and Alexa compatible. A unit with digital temperature control will display important information about the temperature and energy your unit is consuming.
Additionally, most wall AC’s come with removable filters that require cleaning. Choose an air conditioner with filters that are easy to access and also easy to clean. This will allow easy cleaning without the need to involve a professional.
