You need to consider factors like noise level, especially for bedrooms; the ease of installation and window kit design; and whether you want additional functions like a dehumidifier or fan mode. My goal with this list is to help you cut through the marketing jargon and find a portable air conditioner that perfectly fits your space and budget. I’ve focused on models that are reliable, effective, and offer a good value for your money in 2025.

Beyond its core cooling power, the Whynter is packed with great features. It also functions as a powerful dehumidifier, removing up to 101 pints per day, and has a fan-only mode for circulating air on milder days. The unit includes a washable pre-filter and an activated carbon air filter, which is great for improving air quality. It’s not the quietest model on the market, but the sound level is reasonable for its power. Setup is straightforward with the included window kit, and the built-in rolling casters make it easy to move from room to room. For those who need serious, efficient cooling, this is a fantastic investment.
Pros
- Highly efficient dual-hose design cools rooms quickly

LG LP1419IVSM Smart Wi-Fi Enabled Portable Air Conditioner
For those who love smart home integration, the LG LP1419IVSM is a standout choice. This unit brings the convenience of Wi-Fi control to your cooling needs. I found the LG ThinQ app to be very responsive, allowing me to turn the unit on or off, adjust the temperature, and switch modes from anywhere using my smartphone.

- Smart Wi-Fi control and voice assistant compatibility
- Quiet and energy-efficient dual-inverter compressor
- Provides consistent cooling with variable speed operation
Cons
- Higher price point than basic models
- Still uses a single-hose system, limiting peak efficiency
SereneLife SLACHT148 Portable Air Conditioner
The SereneLife SLACHT148 is a great budget-friendly option that doesn’t sacrifice essential features. This compact unit is one of the most lightweight and portable models I’ve tested, making it perfect for renters or for moving between rooms frequently. Despite its smaller size and lower price, it packs a respectable 14,000 BTU punch, suitable for rooms around 450 square feet. The setup is incredibly simple, with a straightforward window venting kit that took me less than 10 minutes to install.
It operates as a cooler, dehumidifier, and fan. The control panel is basic but functional, with a remote control for adjusting settings from across the room. I found the cooling performance to be adequate for its size; it won’t cool a large, sun-drenched room as quickly as a premium dual-hose model, but for a bedroom or office, it works just fine. The noise level is what you’d expect for a unit in this price range—noticeable but not overwhelming. If you need an affordable, no-frills portable air conditioner that gets the job done, the SereneLife model offers excellent value.
Pros
- Very affordable price point
- Lightweight and easy to move
- Simple and quick installation process
Cons

Buying Guide: 10 Best Portable Air Conditioners | 2025
When the summer heat hits, a portable air conditioner can be a real lifesaver, especially if you’re renting or don’t have central AC. I’ve tested a bunch of them, and the key is to find one that fits your specific space and needs. It’s not just about picking the most powerful one; it’s about finding the right balance. Let’s break down what you should look for before you check out the list of the 10 best portable air conditioners for 2025.
First up, and this is the big one: BTUs (British Thermal Units). This number tells you how much heat the unit can remove from a room. A common mistake is going too big, thinking it will cool faster. But an oversized unit will cycle on and off too quickly, which doesn’t allow it to remove humidity properly, leaving the room feeling cold and clammy. For a small room (150-250 sq ft), look for around 8,000 BTUs. A medium room (300-450 sq ft) needs about 10,000-12,000 BTUs. For larger spaces up to 550 sq ft, you’ll want 14,000 BTUs or more.
Next, consider the noise level. If you plan to use the AC in your bedroom or home office, you’ll want a quieter model. Noise is measured in decibels (dB). A typical conversation is about 60 dB. Look for models that list a “quiet mode” or have a dB rating in the low 50s for sleeping.
You should also think about the installation process. All portable ACs need a way to vent hot air out a window or a wall. Most come with a window kit, but check how easy it is to set up and how well it seals the window opening. Some newer models offer a quick-install design that saves you a lot of hassle. Also, pay attention to where the air exhaust and hose are located. Single-hose models are common but can be less efficient because they pull air from your room to cool the unit and then vent it outside, which can create negative pressure. Dual-hose models pull air from outside to cool the mechanism, making them more efficient for cooling the room air.
Finally, look for extra features that improve convenience. A programmable timer lets you set the unit to turn on before you get home. Wi-Fi connectivity allows you to control the AC from your phone. A good dehumidifier mode is great for sticky climates, and a fan-only mode can help circulate air on milder days. Keep these points in mind, and you’ll be ready to pick the perfect model for your summer comfort.
FAQ
How do I know what size portable air conditioner I need?
The most important factor is the square footage of the room you want to cool. Use BTU ratings as your guide: 8,000 BTUs for rooms up to 250 sq ft, 10,000-12,000 BTUs for 300-450 sq ft, and 14,000+ BTUs for larger areas up to 550 sq ft. It’s better to be slightly under than significantly over, as an oversized unit won’t dehumidify properly. Consider factors like ceiling height, sun exposure, and the number of people usually in the room, as these can affect the cooling load.
What is the difference between a single-hose and a dual-hose portable AC?
This is a major efficiency difference. A single-hose unit uses one hose to expel hot air. To do this, it pulls air from your room, which can create negative pressure and draw in warm air from outside through cracks. A dual-hose model has one hose to bring outside air in to cool the compressor and a second hose to expel the hot air. This self-contained process is much more efficient and cools the room faster, making a dual-hose model a better choice for larger or sunnier rooms.
Are portable air conditioners expensive to run?
Their running cost depends on the unit’s energy efficiency and how often you use it. Look for an Energy Star certification, which means the unit meets strict efficiency guidelines set by the EPA. These models will use less electricity for the same cooling power. While they generally use more energy than a window unit, their convenience for renters and flexible placement often outweighs the slightly higher cost for many people.
Can a portable air conditioner cool multiple rooms?
Generally, no. Portable ACs are designed to cool a single, enclosed space. They work by removing heat from the immediate air around them. If you try to cool an open floor plan or multiple rooms, the unit will have to work extremely hard and likely won’t be effective. It’s best to close the doors and windows in the room where the unit is located to contain the cool air.
Do portable air conditioners need to be drained?
Most modern portable ACs have a self-evaporative function, meaning they use the condensate (the water they pull from the air) to help cool the unit and then exhaust it as vapor through the hose. This means you often don’t need to drain them under normal conditions. However, in areas with very high humidity, the unit might produce more water than it can evaporate, and you may need to empty a built-in reservoir periodically. Some models also offer a continuous drain option with a hose.
What should I look for in the list of the 10 best portable air conditioners for 2025?
When reviewing the list, match the models to the criteria we discussed. Look for the BTU rating that fits your room size, check if it’s a single or dual-hose design based on your efficiency needs, and note the decibel level if quiet operation is a priority for you. Then, see which additional features, like smart controls or a robust dehumidifier mode, are included to find the best overall value for your situation.
