Are you looking for the Best Portable Air Conditioners to cool your home or RV? This guide will walk you through the best and quietest portable air conditioners to buy in 2026.
While central air and window air conditioners are great, they aren’t suitable for every situation or every budget. Sometimes, the best portable AC unit is the best choice for cooling small—to medium-sized areas.
What is the best portable air conditioner to buy? The Whynter ARC-14S air conditioner is the best choice for most homeowners.
A portable air conditioner is similar to a window air conditioner. However, it can easily be moved (on wheels) to any additional rooms where it may be required.
Using standard electrical household current and a simple heat exhaust hose, portable air conditioners exhaust warm air outside while introducing refrigerated cold air into any room.
Portable AC units come in different sizes, are homeowner-friendly, and do not require an outdoor condenser, special wiring, or other professional installation.
Best Portable Air Conditioner in 2026
We researched 16 of the best manufacturers and narrowed the list to the Top 7 Portable Air Conditioners based on Key features, Cooling Capacity, And Price. Here are the 7 Best Portable ACs to buy:
Editor’s Pick: Whynter ARC-14S Portable Air Conditioner
The Whynter ARC-14S tops our list as the overall best portable air conditioner.
Providing the benefits of a proven air conditioner, dehumidifier, and air purifier, the Whynter mobile AC unit is perfect for making your home feel more comfortable year-round.
Whether you need a considerable temperature reduction or want to remove dampness from your air, this Whynter unit has you covered.
Key features of this product include:
14,000-BTU cooling capacity
Auto draining – All moisture is fully exhausted using the Cooling function
Dual hoses
Cools up to 500 square feet
Remote control included
It comes with a storage bag
Reviewers find that this portable air conditioner from Whynter produces cold air, distributes it well throughout a reasonably large area, and doesn’t make too much noise. Many buyers are also quite happy with its ease of use when changing the air filter.
The Patented “Auto Draining” feature exhausts all condensation when using the A/C, eliminating the need to empty a drain pan. However, when using the dehumidifier function, you must open the provided drain pan.
Although this air conditioner is rated for 500 square feet, some users report using it in larger spaces with excellent results.
One issue some people have encountered is that this unit isn’t powerful enough to provide sufficient cooling in poorly insulated rooms or in areas with too much sunlight coming in through the windows, which can heat the area.
While the users’ lack of insulation is more involved, a simple curtain or some drapes can solve the problem of the sun heating the room and allow the air conditioner to do its job without having to fight the sun’s effects.
“Editor’s Pick” – Whynter
Runner Up: Serene Life 12,000-BTU Portable Air Conditioner + Heater
Second in our portable AC reviews is the Serene LIFE 12,000-BTU Portable Air Conditioner. Like the ARC-14S, this model acts as an air conditioner and a dehumidifier, though it does not include air purification technology.
However, the Serene Life unit also includes a Heater, making it an excellent option for larger spaces.
Key features of this product include:
12,000-BTU cooling and Heating capacity
Single Hose
Cools or heats up to 500 square feet
Remote control included
Built-in 100-pint dehumidifier
People who have purchased this portable air conditioner find it an excellent fit for various uses, from providing extra cooling in a bedroom to being the sole air conditioner in small apartments.
This model’s advantages include its excellent cooling capacity and relatively quiet operation. Several buyers have also commented on the value of this air conditioner, noting that it is reasonably priced for its features and capabilities.
The only real downside to this portable air conditioner is that it is a single-hose model rather than a dual-hose model. Dual-hose models tend to cool rooms more quickly and remove warm air more efficiently.
However, the Serene LIFE unit makes up for its single-hose design with excellent cooling performance.
“Runner-Up”: SERENE LIFE

Best Portable AC With Heater: BLACK + DECKER 14,000-BTU Portable Air Conditioner + 11,000-BTU Heater

Although it isn’t a compact model, it is reasonably small, allowing it to be used in cramped rooms without taking up excessive floor space.
One downside of this model is the weatherstripping used to insulate the window into which its hose is fed. According to some reviewers, the material that comes with the air conditioner isn’t as durable as it could be and is prone to breaking.
However, this problem can be easily fixed by using commercially available residential weatherstripping material in place of the weatherstripping that comes with the unit.

Frequently Asked Questions (FAQ)
How Does a Portable Air Conditioner Work?
A portable air conditioner uses a refrigerant to absorb heat from the air in a room and then releases that heat outside. A refrigerant is a particular type of gas that can change from a liquid to a gas and back again.
When the refrigerant is in a liquid state, it absorbs heat from the air. When it is in a gas state, it releases heat.
A typical portable air conditioner has one hose. However, some venting options include Two Hoses.
One hose blows hot air outside through a window, and the hot, humid Room air is drawn into the unit through the portable air conditioner intake.
Can You Buy a Portable AC Without a Hose?
Many people, and rightly so, wonder if you can buy a Portable AC without a Hose, and the answer is no.
A Portable (AC) Air conditioner is engineered to collect and expel hot air from a room through an exterior window-mounted hose while introducing cold refrigerated air back into a room.
It would be inefficient to leave warm air inside a room without removing it while introducing cold air into the same room.
I’ve been asked a similar question: Can I buy a Ventless Portable Air Conditioner? And again, no, because a portable air conditioner without a vent (Hose) to remove the warm air from a room being cooled would defeat the purpose.
The only Alternative to a vented Portable AC unit with a hose is an Evaporative Air Cooler (or Swamp Cooler). Swamp coolers can somewhat lower the room temperature by circulating evaporated air over the top of a cold water reservoir/tank. Click the link above to see details for an Evaporative Air Cooler.
What Size Portable Air Conditioner Should I Buy?
The size of the portable air conditioner you need depends on the room you want to cool. You should also consider your climate. If you live in a hot, humid climate, you need a larger unit than you do in a hot, dry climate.
All of the portable air conditioner reviews we include above indicate the recommended cooling capacity based on the size of the room(s) you plan to cool. Remember to consider the specific Portable A/C capabilities, as noted above.
If you try to use an air conditioner with a capacity that’s too low for a large room or apartment, you’ll likely find that it cannot provide the cooling you expect, and your comfort and AC equipment will suffer.
How Do You Install a Portable Air Conditioner?
To install a portable air conditioner, install the manufacturer-supplied window kit, connect the portable AC’s exhaust vent/hose to the window kit, plug the portable AC into the window kit, and enjoy the cold air.
If you’re a visual learner, check out this article from WikiHow. It provides step-by-step instructions and diagrams to help you install your portable air conditioner correctly.
What Are the Most Important Features of a Portable Air Conditioner?
Here are the most essential features to consider when buying a portable air conditioner:
- Energy efficiency: Portable air conditioners can be expensive, so choosing an energy-efficient model is essential. Look for an Energy Star-certified model that meets specific energy efficiency standards.
- Noise level: Portable air conditioners can be noisy, so if you’re sensitive to noise, choose a relatively quiet model. Look for a model with a noise level of 60 decibels or less.
- Features: Some portable air conditioners have additional features, such as dehumidification, fan-only mode, and remote control. Consider which features are important to you, and choose a model that includes them.
- Warranty: Portable air conditioners typically have a one-year warranty. If you’re buying a more expensive model, you may want to consider one with a longer warranty.
What is the Cheapest Portable Air Conditioner?
In our reviews of cheap portable ACs, consider the 5,300 BTU portable air conditioner from Midea.
However, the cheapest may not always be the best. Another affordable AC unit is the 14,000 BTU Black + Decker portable AC model, which also gets the job done efficiently and at a great value.
Prices for these air conditioning units range widely, so there are options for almost every budget. If you’re working with limited resources, a value-friendly model like the BLACK+DECKER 14,000 BTU is the right choice.
If your budget is higher, you may get more utility from a higher-end selection, such as the Whynter ARC14S, which is rated our best portable air conditioner.
Conclusion:
The best portable air conditioner for you will depend on what you need from it and how you intend to use it. The models listed here, though, are among the best today.
