A portable air conditioner (PAC) is a self-contained portable system ideal for cooling single rooms. Offices, server rooms, bedrooms, and garages are warmer than other areas of the houses because of the lack of proper air circulation and ventilation. We all need to eliminate heat and for that purpose a portable air conditioner is the quick and economical solution. The average unit can cool a 100-150 sq. Ft room.

In this in-depth buying guide, we explain what ventless portable air conditioners and how they work.


How do portable air conditioners work?

Portable air conditioners work basically the same way as built-in air conditioning : sucking in warm and humid air, cooling and dehumidifying it. Many models come with a dry mode — to dry out the air, so it doesn’t feel chilly and clammy.

There are two options to consider when buying a portable air conditioner: ventless and dual hose…often referred to as single exhaust hose or dual hose AC respectively.

Ventless portable air conditioner (explained)

Ventless. Portable Air Conditioner DiagramA ventless portable air conditioner is a compact air cooling system that features no exhaust horse and can be moved from place to place with ease. A ventless portable air conditioning unit uses a fan to draw air into its cooling chamber.

Water is collected from the air inside your room. And of course, that water has to go somewhere. In this case it is delivered straight to the tank within the A/C unit. Periodic draining will ensure that your portable air condition continues doing what it’s supposed to do.

One hose systems may take longer to heat or cool the area, but the tradeoff is a slightly lower energy bill overall.

Dual hose portable air conditioner (explained)

Dual Hose Portable Air Conditioner DiagramA dual hose portable air conditioner is an air conditioner that is operated using two hoses. A dual hose portable A/C takes in air from the outside via one hose, cools it, and pushes it out into the space. The warm air from the condenser needs to be removed from your room somehow. Your room is made cooler by removing heat and humidity from inside and discarding it outside. These best position for a dual hose portable air conditioner is by your nearest window. There are options for Venting Portable Air Conditioners Without a Window. You can vent it through a doorway or wall cutout.

Does It Matter If I Don’t Vent My Portable AC/Heater?

It matters a lot! The heat that is generated with these components must be vented to the outside. Otherwise the room will not cool. That is why portable air conditioners use an exhaust hose.

Product Research

We did intensive research and found many portable air conditioner units. These units are compact and can go anywhere you go. They also cut costs and maintain the optimal level of temperatures.

It’s worth mentioning the modified cooling and heating testing requirements revised a previous rating system and introduced a new rating. Combined Energy Efficiency Ratio (CEER) is the new rating system used in our reviews.

The units on the heftier side of the price range tend to demonstrate higher efficiency, and therefore operate more quietly than units that are cheaper. Most portable air conditioners range between 40 and 60 decibels. Each AC can be moved from one place to another to keep it cool and fresh.
