Many people worry about the lack of windows in their house when purchasing a portable air conditioner. This is understandable as most units require an opening through which they can suck in air and expel hot, humid air. However, some models can be installed without an external vent. Such models are known as Portable Air Conditioners. Let’s dive deeper to know more about them.

What is a Portable Air Conditioner?

A portable air conditioner is an appliance that cools the air by blowing it over cold coils and then blows the cooled air into your room. It’s perfect for those who don’t want to spend money on a central AC unit or can’t install one in their home because of lack of space. Portable units are also great for people with allergies as they filter out dust particles, pollen, mold spores and pet dander from the cooling process.

If you’re looking for relief from hot weather this summer without spending too much money, consider purchasing a portable AC unit! They’re easy to use and affordable, so you’ll be able to stay cool all summer long.

Buying Guide 

If you’re in the market for an air conditioner, it’s essential to know what type of unit will work best for your needs. There are few factors you need to consider before choosing to purchase a specific unit. Have a look.

Right size

Before you buy one, it’s essential to know what size will work best for your needs. If you live in a small apartment or house, then a 10-12k BTU unit should do the trick. However, if you have more space and want to cool down several rooms at once, then go with something more significant, like 18-22k BTUs of power. You’ll also need to consider how much noise level you’re willing to tolerate because some models are louder than others due to their design and features.

Size of the room

The size of the room is essential when considering which model to buy. If you have a small space, it may be better to get a smaller unit to cool down the area quickly and efficiently. However, if you have square footage in your home or office, it might be worth investing in a larger unit to don’t need to turn it on as often.

When deciding on what type of portable air conditioner is best for your needs, consider how much space there is in the room and how often you plan on using it. This will help determine which one would work best for your situation.

Condensation and Draining

Condensation and Draining are two critical considerations when buying a portable air conditioner. Portable air conditioners work by drawing in warm, humid outside air through the front grill and blowing it over cold coils to cool it down. This process creates condensation on the inside of the unit that can drip onto your floor or furniture if not appropriately drained. You also need to make sure there is enough space for water drainage at the back of your unit, so you don’t have any leaks.


Portable air conditioners are an excellent option for those who want to cool their home without the hassle of installing central AC. They’re also great for people who live in apartments or homes with no access to ductwork. The set-up process is relatively simple and can be done by anyone with basic DIY skills, so don’t worry if you don’t have any experience.
