With the need for cooling down in the summer comes the desire to invest in air conditioning at home, and a quick and simple solution if you don’t have central AC is a portable air conditioner. Great for a single room or larger open space, you’ll need the right setup, power, and model to meet your needs. You’ll also want to consider how much it costs for both the unit and to run it in Canada. This means paying attention to specs like BTUs, installation requirements, maintenance, physical size, and convenience.
There’s a portable air conditioner model to meet every household and individual need. Plus, there are benefits of air conditioning beyond comfort. Looking for a new one for your home? Here, I’m highlighting some of the best picks this year.
What is a portable air conditioner?
First, what is a portable air conditioner? A portable air conditioner is a freestanding appliance that sucks hot air from a room, cools it, and expels it out a hose that vents through the window. It’s easy to install, mounted at a window using an included venting kit. It either has a self-evaporating function to recycle condensation back into the air or requires water drainage. There are ventless models for smaller spaces and mini air conditioners for personal cooling.
Most come on castors for easily moving them from room to room. They usually come with simple remotes and basic features like 24-hour timers. Learn more about portable air conditioners and how they compare to other types, including window air conditioners and mini-split models, in our air conditioners buying guide.
Single-hose vs. dual hose models
One differentiator you might notice is that some portable air conditioners come with a single hose to vent out a window while others have two. Naturally, dual-hose portable air conditioners are more efficient. One hose pulls outdoor air to cool the compressor while the second hose exhausts it. This results in the ability to cool a room faster. It also eliminates the negative pressure you can get with a single-hose portable AC, which can pull in hot air through gaps and cracks, making it more challenging or slower to cool a room.
Dual-hose models are more expensive but they work more efficiently. They are also larger and installation is a bit more complicated, but you might want to consider one for a larger, open space, one that is often occupied by many family members, or if you live in an especially hot and humid climate.
Who should get a portable air conditioner?
A portable air conditioner is suitable for a single room, like a nursery or bedroom, or open concept space. They are also good for apartments, condos, and small homes. That’s especially for rentals where you aren’t permitted to install something permanent. They’re also a budget-conscious option if you only need cooling in one room and don’t want to (or can’t) install central air conditioning. If you live in a cooler climate and only need AC for a limited time during the year, you might find it better to invest in a portable AC versus central AC.
What to know about sizing and BTUs
Properly sizing your portable air conditioner is an important first step before considering models. Use a general guide for British Thermal Units (BTUs) alongside a measurement of the square feet of space to be cooled. BTUs measure heat energy and cooling capacity of an air conditioning unit and tell you how much space they can effectively cool. For a 100-150 square-foot room, for example, a 5,000 BTU portable air conditioner will work. For a room that’s 300-350 square feet, you’ll need one that’s at least 8,000 BTU. Since portable air conditioners can be less efficient than window air conditioners, it’s a good idea to go up in BTUs just in case. Here’s a handy guide you can follow for some of the most common room sizes.
| Room Size | BTU Required |
| Up to 150 sq. ft. | 5,000 BTU |
| 150-250 sq. ft. | 6,000 BTU |
| 250-350 sq. ft. | 8,000 BTU |
| 350-450 sq. ft. | 10,000 BTU |
| 450-550 sq. ft. | 12,000 BTU |
| 550-700 sq. ft. | 14,000 BTU |
BTUs vs. DOE
The latest portable air conditioners show a more accurate DOE label in place of or in addition to BTUs. This Seasonally Adjusted Cooling Capacity (SACC) measurement accounts for the heat the portable AC can generate itself, and thus lowers the BTU number accordingly to factor that in. For example, a 10,000 BTU portable air conditioner may be labeled as 6,500 BTU when using the new DOE label. Go with the latter figure as it is more accurate.
Window size
Don’t forget to check the size of your window frame. I live in a 100-year-old home, and when we first moved in, we got a portable air conditioner for my son’s bedroom before getting central AC. We had to use a cut-out for the window because it’s an unconventional size. Venting kits can be suitable for horizontal windows, vertical windows, or both.
ENERGY STAR Rebates in Canada
Most Canadian provinces offer rebates on the use of qualifying ENERGY STAR products. It varies by province, potentially even city and local utility company. Visit provincial websites or contact companies like BC Hydro, Enbridge, Hydro-Québec, and Efficiency Nova Scotia to find out more information as it’s always subject to change as well. But this can help you save on the overall cost of an air conditioner in Canada.

Earning high marks from Best Buy shoppers, this Hisense model is perfect for a small living room, basement, home office, bedroom, or nursery. It runs at just 50dB, similar to the sound of a light rainfall. So, it won’t disturb you, even if you leave it running overnight. It installs with a single hose, has two fan speeds, and four-way air direction so you don’t feel a blast of cold air in one spot. Some shoppers say it’s powerful enough to cool even two small rooms. They praise it for being quiet and easy to install. One customer calls it “one of the best portable air conditioners I have ever gotten.”

This single-hose portable air conditioner is perfect for a bedroom or smart apartment or condo. While we haven’t reviewed this specific model, our reviewer checked out the more powerful 12,000 BTU version. She loves how easy it is to maneuver, install, and operate with the handy remote. Most Best Buy shoppers who bought it say they’d recommend this unit, appreciating that it cools quickly. Some admit it’s not as quiet as others, rated at about 53-59dB.

Best for the Living Room: Insignia NS-AC10PWH5-C 10,000 BTU (250 sq. ft.)
Good for a living room or open-concept basement, this compact, upright unit (12.8 x 27.6 x 11.6 inches) can comfortably sit in a corner by the window without getting in the way and vents from a single hose. A best-seller for Best Buy Canada, it ranks high for ease of use and cooling ability. One customer says it only took them five minutes to install it! It doesn’t come with a detailed manual so you may have to look up instructions online. It also runs louder than some other higher-priced units, rated at 51-56dB with real-world tests suggesting closer to 61dB, so keep that in mind.
ENERGY STAR Certified? No

Best for Large Spaces: Insignia NS-AC14PWH5-C 14,000 BTU (400 sq. ft.)
Looking for something for an open-concept main floor, entire condo, or large basement? This single-hose model fits the bill with plenty of cooling power to accommodate a large home, even when you have the neighbors over to watch the big game. A Best Buy Canada bestseller, shoppers find the noise at about 56dB it makes worth it for the effective cooling. A Swing mode, activated by remote, adjusts the direction of the airflow so you aren’t freezing in one corner of the room while your spouse is sweating in the other. Plus, since it automatically turns off once it reaches the desired temperature, it isn’t running 24/7 to overcool or waste electricity.

Price Range: Available from $350-$650 at Best Buy (check sales)
Best for Humid Areas: Hisense 3-in-1 AP1024CW1LA 13,500BTU (450 sq. ft.)
Operating at a decent 52dB, this single-hose portable air conditioner is also stylish in a Charcoal Grey finish. Notably, it has a built-in dehumidifier that can remove excess moisture from a room, one of the many benefits of a dehumidifier. You’ll want it for especially humid rooms like a basement or, in my home, the bedroom on one side of the house. It both cools and removes humid air, releasing dry air back into the room. This helps prevents potential mold growth, structural damage, and health issues. Since the portable AC is self-evaporating, you don’t have to worry about drainage. It’s also a smart model that works with the Hisense Connect Life app for remote control. It even supports Amazon Alexa or Google Assistant for voice control. Best Buy shoppers love the sturdy window panels and ease of set-up.
ENERGY STAR Certified? No

Best for Heating & Cooling: Hisense AP0825TW1SAHP 8,000 BTU (350 sq. ft)
Not only in this model suitable for homes in seasonal climates, it’s also sleek and tall so it doesn’t take up too much floor space. That means it will fit in smaller corners that others won’t. If you live in a province that can go from freezing cold one day to humid the next (hello, Ontario!), you can get both cooling and heating from this same unit. The tower-shaped portable AC employs a two-hose design and works with a companion app for remote control as well as voice assistance. It’s incredibly quiet at just 39dB, too. You get three cooling and fan speeds and four-way airflow along with digital temperature adjustments. A highly rated, best-selling model, one Best Buy shopper who purchased this model last summer says it’s a “well-built…practical all-season unit.”

Best Smart Model: Danby Danby 3-in-1 Portable Air Conditioner – 12000 BTU (500 sq. ft.)
Multiple models on this list have smart features, but this Danby unit ups the ante. It combines Wi-Fi with powerful cooling, quiet operation with Silencer Technology bringing it down to about 53.5dB, and a tiny LED screen. Sit back and use the app to turn it on and off and adjust the temperature. Speak commands with Amazon Alexa and Google Assistant. The included remote works like a thermostat with a Follow Me function that adjusts temperature as you move with it. There’s also a dehumidifier mode. While I haven’t used this specific model, I had a Danby portable AC for my son’s room when we first moved into our home. It was a saving grace, getting him through one of the most humid summers in Toronto. Best Buy shoppers point out that the portable AC unit is rather large with its dual-hose design, limiting it to bigger spaces. But they love how easy it is to set up and operate.

Best High-End: LG 3-in-1 LP1419IVSM 14,000 BTU (500 sq. ft.)
If you’re in a “money is no object” situation, this LG portable air conditioner doesn’t come cheap, but it has tons of premium features. Dual Inverter technology ensures quiet (just 44dB!) and energy efficient operation via a single-hose design. There’s a three-speed fan with an oscillating air vent and four-way air direction. The programmable timer includes an auto cool option so it runs on its own. It removes moisture from the air to control humidity levels, and the included remote is a step above as an LCD to complement the top-panel digital controls. Of course, it has built-in Wi-Fi, connecting to the ThinQ app so you can control it alongside other LG smart appliances. Also enjoy Amazon Alexa or Google Assistant voice control. Best Buy shoppers call it “very high quality,” a premium unit for those who seek one.
ENERGY STAR Certified? No
Price Range: Available from $1,050-$1,230 at Best Buy (check sales)
Best Energy Efficient: De’Longhi 3-in-1 PACEM369S-6AL 12,000 BTU (500 sq. ft.)
Every model on this list is designed to operate efficiently, but this De’Longhi air conditioner purports to offer less wasted energy than previous models in the brand’s line, even though it isn’t technically ENERGY STAR-certified. Plus, it was made using eco-friendly gas. There are features like automatic dimming of the lighted display at night to both save electricity and reduce distraction. The dust filter is washable, and it has push-button controls. A simple, mid-range machine, this unit runs at a respectable 53dB. It’s worth noting that the single exhaust hose is short so it might not be suitable if you have a high window. There’s a neat slot on the unit to hold the remote so you won’t lose it, a nice feature since it doesn’t have Wi-Fi.
ENERGY STAR Certified? No

Final considerations before choosing
There are a few things to keep in mind before selecting the best portable air cooler for your home. Here’s a handy question checklist.
- What size do I need? Make sure you map out the space you have by the window to accommodate the best portable air conditioner. Choose the right physical size, not just power.
- How many BTUs? Along with the measurements noted above, consider factors that can impact cooling. How much sun does the room get? Does the room uses appliances that generate a lot of heat (kitchen, laundry room)? Are there are high ceilings? Is the room often occupied with many bodies, like the living room? If any of these factors apply, get one with more BTUs than the measurements advise.
- Useful smart features. Some standing air conditioners have convenient smart features like auto shut-off, Wi-Fi and companion apps, and voice control that are worth considering.
- Maintenance. Maintenance and cleaning is important, including emptying the water reservoir, washing the filter, and vacuuming vents and coils.
- Sound level. If it’s for a nursery, bedroom, or home office, prioritize one that runs at a low decibel level so it isn’t distracting.
Be on your way to a cooler home
Ready to cool your home? Before you realize you’re sticking to the leather couch from sweat, or you’re frantically digging around for the mini fan you bought for vacation to get some relief – any relief – from the heat, set up a portable air conditioner. Even if you eventually get central AC like I did, you might still find use for it. We often still use fans in the bedrooms in the summer because the air circulation isn’t as good on the upper level as it is on the main floor (the downside of an older home!) I sold our portable AC after we got good use out of it, and got a decent amount for it, too. The investment is worth it for your comfort and health, not to mention the health of your home.

FAQs
How many BTUs do I need for my room?
This will largely depend on the size of your room, but for a bedroom that’s anywhere from 150 to 250 square feet, 6,000 BTUs should suffice. Make sure to look at the SACC number and consider adding 10-15 per cent more if you have high ceilings (over eight feet) and/or it’s a south-facing room that gets a lot of sun.
What’s the difference between single-hose and dual-hose portable ACs?
Single-hose models have one hose that vents out a window and dual-house models have two. Dual-hose models working more quickly and efficiently since the second hose pulls in outdoor air to help cool the compressor, removing negative pressure. But they’re larger, more expensive, and more complicated to install.
Are portable ACs worth it in Canada?
Yes, they’re especially worth it in Canada since residents generally only use AC for a few months out of the year. Some parts get especially hot and humid temperatures during the core summer months as well. They’re a cost-effective solution you can put away at the end of the season.
What’s a good noise level for a portable AC?
45-52dB is generally considered quiet, which is comparable to the sound of rain falling, a library, or a low hum.
