Quietest Portable Air Conditioners – Cool Off in Peace

Air conditioning becomes a necessity instead of a luxury when you’re living in a hot and humid locality. Nothing tops entering your home after a long, hot day and feeling a cool blast of air hit you ever so pleasantly.

However, the cost that comes with regularly fixed air conditioners, their installation, and their electric bills is not pretty.

Why not opt for a portable air conditioner instead? Along with the added convenience of being able to serve multiple rooms rather than just staying fixed in one, a portable air conditioner could cut down your electric bills and fit your budget better.

The noise that comes with many portable units, however, can be a nuisance. That is why we have compiled some of the better models available in our list of the quietest portable air conditioners.

Another challenge that some people may face with portable air conditioners is venting. Since these air conditioners blow hot air outside through a hose, there must be a way to place the end of the hose through a window or door, while managing a seal so that the cool air doesn’t escape the room.

Although these air conditioners come with a window venting kit to serve this purpose, some people still may have difficulty establishing a seal. Another potential problem due to the hose is that options for placement get limited.

In such instances where an exhaust hose is the source of problems, you can opt for a portable air conditioner without a hose. These are actually evaporative air coolers which work by releasing water vapors into the air for a cooling effect.

However, this makes them suited only to warm, dry climates since they will obviously worsen the humidity in already humid weather. Moreover, instead of keeping your room airtight, they require you to keep a window or door open so that your house doesn’t get saturated with humidity.

Ventilation is always key to have an evaporative air cooler perform efficiently. Further on, we have included some of the best evaporative air coolers if you decide to go with this option.

A Guide to Buying the Quietest Portable Air Conditioner or Evaporative Cooler

Bearing hot temperatures can be no fun. On days when the heat just leaves you feeling agitated, setting up your portable air conditioner can be a great help.

If you’re planning on buying one, you should know there’s nothing like ’one model suits all’. Here are a few tips to guide you on which kind of product will be the most suitable for you.

Dry or Humid?

If you’re confused between an air conditioner and air cooler, the humidity factor in your environment will help you decide.

For humid environments, air coolers are usually not the best choice since they owe their cooling effect to releasing water vapors in the air. An air conditioner with a built-in dehumidifier would best serve a humid environment.

However, for hot, dry environments, an air cooler could be a great choice.

Room Size

Portable air conditioners are meant for specific room sizes. Any room larger than the maximum size indicated to be served by an AC unit will usually not be effectively cooled.

In addition, your unit will have to work harder, which may generate more noise and compromise its quietness. It is always better to go for a unit meant for rooms slightly larger than your own, for best results.

Options for Placement

If you have space by a window or door in your room, you can easily accommodate a portable air conditioner since its hose requires an outlet to throw hot air outside a room. Air coolers are pretty flexible in terms of placement.

Noise Level

For light sleepers, it is recommended to check the noise level of the appliance (decibel ratings) first before making a purchase. What use is a powerful cooling AC if it will keep disturbing you by making a racket?

Usually, the decibel rating of portable air conditioners falls between 50-60 decibels. However, keep in mind that most manufacturers mention the noise at the highest setting, which means if you operate your machine at a lower setting it usually won’t be as noisy.

You should also know that the decibel scale increases exponentially, so much that a 5-decibel difference is actually a 50% difference in loudness!

Cooling Capacity

For portable air conditioners, units with higher BTU have a larger cooling capacity and can be employed for bigger rooms.

For evaporative air coolers, the CFM value stands for Cubic Foot per Minute – the amount of air that goes through your room each minute. To calculate what CFM swamp cooler would be suitable for you, multiply the area of your room in square feet by the height of the room in feet, then divide by 2.

Functions

Features like multiple fan speeds, easy-to-clean filters, smooth-gliding wheels, and built-in dehumidifiers etc indicate an upgraded machine that you should try out for yourself.

Also, check customer reviews to make sure if the appliance does deliver what is promised in the description.

Happy Shopping!

With the plethora of portable air conditioner models available in the market, deciding which one to go for can be a challenge.

Now that you have the complete guide to shop for the quietest portable air conditioner, there is no need of unnecessary confusion. Glide any of these top-rated products in any room to feel cool and fresh, and say goodbye to a sweaty, sticky self!
