Ultimate Guide to the Best Portable Air Conditioners of 2024

Best Portable Air Conditioners

Portable air conditioners provide an excellent way to cool a room when the temperatures outside heat up. You may have one to assist in a bonus room, basement, or garage. Even if you have a central AC system in your home, a portable AC unit can help you get cooler air to a room that needs some extra help. Portable AC units offer flexibility, letting you move them from room to room as needed. Having used more than a few of these units, we can help you find the best portable air conditioners to match your particular cooling needs.

Why Invest in a Portable Air Conditioner?

As we mentioned, portable air conditioners make any room in your home more comfortable. These self-contained units move easily from room to room. It’s their portability that makes them the perfect choice for meeting spaces, offices, and dorm rooms. You can easily store them in a closet when not in use.

Choosing the Best Portable Air Conditioner for Your Needs

Choosing the best portable air conditioner for your intended purpose starts with identifying the key features to consider. You’ll be more satisfied with your purchase if you consider the size of your room and the unit’s energy efficiency rating. Noise levels are another primary consideration when choosing the best portable air conditioner.

Considerations Based on Room Size

The room size you are cooling is the most important factor in choosing the best unit for your needs. The right-sized AC unit operates more efficiently, which lowers your operating costs. 

Room sizeSquare feetBTUs
SmallLess than 150 sf5,000 BTUs
MediumUp to 350 sf8,000 BTUs
LargeUp to 800 sf12,000 to 14,000 BTUs

Energy Efficiency Factors

Energy Star certification is one of the most important factors to look for when choosing a portable air conditioner. Other features to look for include automatic shut-off, programmable timers, smart sensor technology, multi-speed fans, and sleep modes.

Noise Levels

Excessive noise from an AC unit can be disruptive and distracting, whether you’re trying to sleep, work, or relax. Features that reduce noise, like dual inverters, noise-reducing fan blades, and compressor insulation, result in quieter units. Find one less than 50 to 60 decibels, which is about the same as a quiet conversation.

Understanding Different Types of Portable Air Conditioners

Whether you have no air conditioning or are looking to supplement what you have, investing in a portable AC unit makes sense. Before taking a closer look at the best portable air conditioners, it’s important to understand the different types to help you understand which is the best for your needs.

Single Hose Portable Air Conditioners

Portable air conditioners use the same basic design principles as other types of AC units, and they vent heat and moisture as a by-product of the cooling process. The main difference in various portable units is how they vent exhaust, and in single-hose portable air conditioners, there is only one hose, which is used to vent heat outside through a window.

Single-hose portable ACs are more affordable and easier to install than dual-hose units but are less efficient. Since air is constantly being pumped out of the room without being replaced, the negative pressure in the room causes air to come in through cracks and leaks, resulting in less efficient operation.

Dual Hose Portable Air Conditioners  

Although they cost more upfront, dual-hose portable air conditioners are more efficient and less expensive to operate. They draw in fresh air from the outside through one hose, cool it, and then emit the warm air back outside through a separate hose. This process allows them to cool the area more effectively, making it trickier to install.

Ventless or Evaporative Air Conditioners

While ventless portable air conditioners use refrigerant, they don’t require an exhaust hose or ducting system, and no installation is required. They are cheaper to install and maintain, and they are smaller and more portable than other types of AC units, but they are less efficient.

Also known as swamp coolers, evaporative coolers use a different process to cool air in a room. Instead of using a cooling system with coils and a refrigerant, evaporative coolers use water and a fan to cool the air. They have a water tank, but they don’t require an exhaust hose or vent. Unlike other portable ACs, evaporative coolers can be used outdoors, but they are ineffective in regions with high humidity.

FAQs about the Best Portable Air Conditioners

How Does a Portable Air Conditioner Work?

Portable air conditioners use the same principles as all air conditioners. They draw warm air in over coils that contain refrigerant. As the liquid condenses, the air is cooled, and the unit pumps it into the air-conditioned room.

Do Portable Air Conditioners Use a Lot of Electricity?

Portable air conditioners use a lot of electricity, but they are more efficient than old, outdated AC units. However, if you only spend time in one part of your house, portable ACs can be more efficient because you aren’t cooling your entire building.

Can a Portable Air Conditioner Cool Multiple Rooms?

Portable air conditioners aren’t meant for cooling multiple rooms, but they can be moved easily, and they are much less expensive than whole-house split systems.

How Often Should I Clean or Replace the Filters in My Portable AC Unit?

You should clean or replace your air filters at least once a month, depending on how much dust there is where you live. Some portable AC units have a “check filter” reminder light for ease of use.

What is BTU and Why Does It Matter?

BTU stands for British Thermal Units, and it’s a measurement of heat. Air conditioners are rated in BTUs according to how much heat they can remove from a room within one hour.

The Difference Between BTU ASHRAE and DOE

Something interesting happened once the industry started releasing portable AC units. They, of course, needed a way to rate their efficiency. Naturally, they went with the same measurement ratings and specifications used for window units and wall units. That presented some problems.

For one, portable units emit more heat into a room than their window-located counterparts. That meant that units with the same BTU ratings weren’t operating in a way that felt the same in a room of the same size. The industry needed a new ratings system to even the playing field.

In 2018 manufacturers started using a new DOE BTU rating. The number gives a much more accurate sense of the unit’s ability to cool since it takes into account the exhaust heat emitted by the portable air conditioner.

That ASHRAE rating still gives an accurate number for the technical cooling performed, but consumers want to pay closer attention to the BTU (DOE) number in order to understand the unit’s real-world cooling potential.
