Big Portable Ac Unit Reviews and Buying Guide

Big portable AC units are a game-changer for hot summer days, especially for those without a permanent AC installation.

They come in a wide range of sizes, from compact units that can cool small rooms to larger units that can handle whole houses. Some big portable AC units can even cool spaces up to 1,000 square feet.

When choosing a big portable AC unit, consider the BTU rating, which determines the unit's cooling power. A higher BTU rating means the unit can cool a larger space.

Look for units with a high Energy Efficiency Ratio (EER) for lower energy costs. Some big portable AC units have an EER of up to 13.

Portable AC units are a great way to cool down a room without breaking the bank. You can expect a powerful airflow and fast cooling from units like the TCL Smart Portable Air Conditioner, which can cool a space of up to 250 sq. ft. in no time.

One of the standout features of portable AC units is their connectivity options. The TCL model, for example, comes with Wi-Fi connectivity and a remote, allowing you to control it from your smartphone or from across the room. The LG Smart Portable Air Conditioner also offers Wi-Fi connectivity and can be controlled remotely, as well as with voice control via Amazon Alexa or Google Assistant.

The LG model is also relatively quiet, with a weight of 54.2 lbs and a cooling area of 250 sq. ft. It's a great option for those who want a hassle-free cooling experience. Here are the key features of the two models mentioned:

Portable air conditioners are designed to do more than just cool the air - they can also remove excess moisture from the room. Most portable ACs can remove a significant amount of moisture, often more than a dedicated dehumidifier.

In fact, our portable AC picks can remove up to 161 pints of moisture per day, which is impressive considering many dedicated dehumidifiers in the under-$300 range can only handle 50-80 pints per day.

However, there's a catch - most portable ACs reevaporate the moisture back into the room to improve cooling efficiency. But if you want to keep the moisture out, you can turn on the "dry" mode, which will prevent most of it from reentering the air.

When you use the "dry" mode, you'll need to find a way to drain the excess water, as the unit's water reservoir isn't designed to hold much liquid. Fortunately, many portable ACs come with a port on the back and a length of hose to make draining easier.

An inverter-equipped portable AC can be a more efficient choice, especially on lower settings, where it's quieter and uses less energy.

Inverter technology can make a big difference, but only when combined with a dual-hose design.

Wi-Fi connectivity is a feature that can make controlling your portable air conditioner a breeze.

Some portable ACs can be controlled via Wi-Fi, which is handy for setting schedules or turning a unit on before you head home so your room is cool by the time you arrive.

The TCL Smart Portable Air Conditioner stands out for its Wi-Fi connectivity, allowing you to control the unit via a smartphone app. If you don't feel like downloading the app, it also comes with a remote.

You can also use voice control via Amazon Alexa or Google Assistant with the LG Smart Portable Air Conditioner, making it easy to start or stop your cooling remotely.

Here's a comparison of the Wi-Fi features of the two models:

Portable air conditioners are a great way to stay cool without breaking the bank. They often come equipped with energy-saving modes that can help reduce your electricity bill.

These modes work by adjusting the temperature and airflow to use less energy while still keeping you cool. I've seen some portable air conditioners use up to 50% less energy than traditional window units.

A programmable timer and sleep settings are also a big plus. You can set the unit to turn off or adjust its settings automatically, so you don't waste energy when you're not home or sleeping.

Some portable air conditioners even use eco-friendly refrigerants, which are better for the environment and can last longer than traditional refrigerants.

A dehumidifier is another feature that can help you save money. By removing excess moisture from the air, you can reduce the need for fans or other cooling devices.

The reverse cycle feature is also worth mentioning. It allows the unit to heat as well as cool, making it a great option for year-round use.

Here are some of the money-saving features you can expect to find in a portable air conditioner:

Portable air conditioners are available in four major size classes, but the size of the unit doesn't necessarily dictate the size of the room it can cool. In fact, our research shows that the higher the BTU, the better the unit cools, but it's the newer Seasonally Adjusted Cooling Capacity (SACC) standard that matters, not the traditional BTU rating.

The SACC standard takes into account the inefficiencies of portable air conditioners, such as the hot air that's exhausted out of the room and the heat that's radiated back in through the exhaust hose. This results in a significant drop-off in actual cooling capacity, especially for smaller units.

The actual cooling capacity of smaller units, such as 8,000 and 10,000 BTU units, is especially low, and they'll only work in very small spaces (under 150 sq. ft.) and in mild climates. Otherwise, a larger unit, such as a 14,000 traditional BTU or a really efficient 12,000 traditional BTU unit, is your only option.

Here's a rough guide to the actual cooling capacity of different size classes:

New portable air conditioners are relatively energy efficient, but it's worth looking for Energy Star certification or specific numbers like a CEER above 10, a SEER above 14 in the north and 15 in the south, and an EER above 10.

Noise levels can be a concern when it comes to portable ACs. Most portable ACs only report the decibel (dB) level generated by their lowest or sleep setting. I measured them on high using an iPhone app and found they ranged between 60 to 68 dB.

Dehumidification rate is a key performance metric for portable ACs, with some models removing up to 161 pints of moisture per day. This is often more effective than dedicated dehumidifiers in the same price range.

Most portable ACs reevaporate moisture back into the room to improve cooling efficiency, but some models have a "dry" mode that prevents this from happening. This mode requires you to find a way to drain the unit, as the water reservoir is not designed to hold much liquid.

The strength of the fan in an AC determines how quickly it can cool a space, measured in cubic feet per minute (CFM). A stronger fan can cool a space faster, but it also uses more energy.

Portable air conditioners come in four major size classes: 8,000, 10,000, 12,000, and 14,000 BTU. However, the higher the BTU, the better the unit cools, but it doesn't necessarily mean it can cool a larger room.

The size of the unit doesn't directly correlate with the room size it can cool. In fact, our own research and testing revealed that there's only one size category you should consider, regardless of room size: 14,000 BTU.

Here's why: portable AC units are inherently inefficient appliances. They use the air in the same room they're cooling to cool off their own internal parts, which adds heat back into the room. The new standard for measuring portable air conditioner cooling capacity, seasonally adjusted cooling capacity (SACC), takes into account these inefficiencies.

The SACC rating is a more accurate measure of a portable AC's cooling capacity. For example, a 14,000 BTU unit may have a SACC rating of 7,700 to 12,000 BTUs, while a 10,000 BTU unit may have a SACC rating of 5,500 to 7,000 BTUs.

In fact, there's a wide range of actual cooling capacity among models in the same size category. For instance, the most efficient 8,000 BTU model has the same SACC rating as the least efficient 10,000 BTU model.

Here's a summary of the SACC ratings for each size category:

As you can see, there's a substantial drop-off in actual cooling capacity after accounting for heat added by ducting and hot outdoor air getting sucked into the room. Smaller units, like the 8,000 and 10,000 BTU models, have especially low actual cooling capacities.

In fact, our testing has shown that smaller units will only work in very small spaces (under 150 sq. ft.) and only if the space is not especially difficult to cool. Otherwise, a larger unit, like a 14,000 BTU or a really efficient 12,000 BTU unit, is your only option.

Choosing the right portable air conditioner is crucial to ensure it effectively cools your space. The size of the unit is not directly related to the room size it can accommodate, as you might think.

A common mistake is choosing a unit based on its traditional BTU rating, but this doesn't account for the unit's inefficiencies. The latest standard for measuring cooling capacity, SACC, reveals a wide range of actual cooling capacity among models in the same size category.

In fact, the most efficient models in one category may have the same SACC rating as the least efficient models in another. For example, the most efficient 8,000 BTU model has the same SACC rating as the least efficient 10,000 BTU model.

Here's a rough guide to help you choose the right size portable air conditioner:

Keep in mind that this is just a rough guide, and other factors like the number of people in the room, sunlight, and insulation can affect the required BTU capacity.

Portable ACs are easier to move than window units, thanks to their wheels, but they can be noisier and heavier.

When selecting a portable AC, consider the size of the room you want to cool. Our experts recommend placing the unit away from walls to ensure good airflow, but this may take up more floor space.

You'll want to choose a portable AC that's designed for your room's square footage. A general rule of thumb is to choose a unit that's rated for 100-150 square feet per ton of cooling capacity.

Here are some general guidelines for choosing the right portable AC:

Keep in mind that these are general guidelines, and the actual cooling capacity you need may vary depending on factors like insulation, window size, and the number of people in the room.

Choosing the right portable air conditioner can be a daunting task, but it doesn't have to be. Consider the room size you want to cool and choose a unit with a BTU capacity that matches. A general rule of thumb is to have 8,000 BTUs for every 200 square feet of living space.

A higher BTU unit is not always better, as it can be less efficient and more expensive. Look for units with a high SEER rating, which measures the cooling output per unit of energy consumed. The higher the SEER rating, the more energy-efficient the unit.

Noise level is also an important factor, especially if you plan to use the unit in a bedroom. Look for units with a lower decibel rating, producing less noise while operating. Some units also have a "sleep mode" that reduces the noise level while you sleep.

Consider the size and weight of the unit when choosing a portable air conditioner. Look for units with built-in wheels and handles for more effortless mobility. Make sure the unit's size suits the room you plan to use it in and that it will fit through doorways and windows.

The table below provides a sizing guide for portable air conditioners based on room size:

However, it's essential to note that other factors, such as the number of people in the room, the amount of sunlight that enters the room, and the room's insulation, can also affect the required BTU capacity. Therefore, it's always best to consult a professional to ensure you choose the correct size portable air conditioner.

In reality, the actual cooling capacity of smaller units is especially low. Our testing has shown that smaller units - in the 4,000 to 7,000 SACC BTU range - will only work in very small spaces (under 150 sq. ft.) and only if the space is not especially difficult to cool.

The Midea portable AC unit is a versatile and efficient cooling solution for small spaces. It's designed to cover up to 700 sq ft.

Here are the key specifications to consider:

The unit's outlet also features a unique oscillation feature, allowing for adjustable movement or complete stop at any angle.

When shopping for an air conditioner, it's essential to know the key specs of the product. Here are some crucial details to consider:

The coverage area of an air conditioner is a critical factor to consider. Typically, manufacturers provide the number of square feet a unit can cool, assuming an average ceiling height of around eight feet.

A good rule of thumb is to figure roughly 20 BTU per square foot of space. This means that for a 700 sq ft room, you'll need an air conditioner with a high BTU rating.

The BTU rating of an air conditioner determines its cooling capacity. In the case of portable ACs, the Department of Energy came out with the seasonally adjusted cooling capacity (SACC) rating in 2017, which takes real-world operating conditions into account.

Here are some key specs to look out for in an air conditioner:

The airflow rate of an air conditioner is measured in cubic feet per minute (CFM). This determines how quickly the air conditioner can cool a space.

Dual-hose units are more complex to build, making them more expensive. They're also more efficient, especially for cooling larger spaces.

A single hose, on the other hand, essentially recirculates the room's air to cool it. This type of unit has one line that runs outdoors to expel exhaust.

If you only have a small space to cool, a portable a/c with a single hose may suit your needs just fine.
