What I like
With a 5.5″ power cord, you won’t have any issue reaching the power outlet. This 15000 BTU air conditioner is capable of cooling a room up to 700 square feet. That’s the size of a large living room or bedroom, which will keep you cool even if you can’t install a central AC unit.
This hOmeLabs unit will save you money on electric bills as it’s energy star certified. Take advantage of its sleep and eco mode to slash your bills as the end of the month while you stay cool. The temperature sensor will keep this unit running at your desired temperature.
Every now and then, you’ll need to replace the air filter. The great thing about window air conditioners is that most of them have a washable air filter. Instead of buying new ones every 3 months, you’ll be able to enjoy a reusable air filter and do less damage to the environment.
The remote control is packed full of features like auto, sleep, speed, timer, display and fan only modes. This unit is quieter than most other window ac units at a rated 52-56 decibels. That’s about as quiet as a light conversation and will help light sleepers fall asleep with ease.
What I don’t like
This model is a bit more expensive than all the other models.
Verdict
While this air conditioner is a bit more expensive than other air conditioners on this list, it’s still one of the most aesthetic and feature-packed units I’ve come across. I think with all the positive reviews in mind and the warranty, it’s hard to go wrong with this unit.

What I like
My favorite part about this 15000 BTU window air conditioner is that you can cool spaces up to 800 square feet. That’s bigger than most average-sized rooms, so the ample power can help cool down your hallways and adjacent rooms.
This air conditioner is energy star certified so you’ll be able to enjoy an energy-efficient unit all year long. With electricity bills on the rise, it’s great knowing that a window air conditioner is going to save you money while you beat the heat.
The remote control will give you access to timer, fan speeds and temperature control. You can also shut the unit off with ease no matter where you are in the room. If you like, you can take advantage of the auto cool mode which will allow you to customize how cold you want your space to be.
After a power failure, you’ll have your settings just after you left them. The installation process is a breeze and the mounting accessories are included with this window air conditioner. The front has a basic display as well allowing you to control your unit should you pass by.
What I don’t like

Verdict

- Cools Up To: 850 square feet

What I like
My favorite feature on this 15000 BTU window air conditioner is that it has a temperature sensing remote control. This allows the unit to sense the temperature where you are, not near the unit. This will keep the cold air flowing and keep you at a comfortable temperature over other air conditioners without this feature.
It’s energy star certified with an energy efficiency ratio of 11.8. At around a 12 EER, that means this air conditioner is efficient as mini-split units which are notorious for being energy efficient! You’ll be saving money all year round even when you’re blasting cold air.
This unit is not only great at air conditioning, it’s great at dehumidifying as well. With 3.8 pints of water removed from the air each hour, you won’t need to deal with hot, sticky air ruining your day. This’ll save you on costs buying an extra unit as well.
This window unit has a filter reset notifier so you’ll know when it’s time to give your washable air filter a rinse for better cooling. Choose from cool, eco mode or fan speed/fan only, and sleep mode. Reviewers mention this unit is super quiet which is great for light sleepers.
What I don’t like
Some purchasers mention that installation was a bit difficult, but all window air conditioners rely on the unit being picked up which may require two people if you’re not capable of lifting 100+ pounds.
Verdict
This is a great 15000 BTU window air conditioner that is energy star certified and will keep you colder over a comparable portable air conditioner. It’s also more efficient, which is great!
- Cools Up To: 875 square feet
- Warranty: 7 years
- Remote: Not included
What I like
While this isn’t a typical window air conditioner, it still does the exact same job. You may notice it looks like a unit out of a hotel or office, because that’s what this unit is meant for. That doesn’t mean you can’t enjoy it win your home, though!
The most impressive bit is the 7 year warranty. Other models on this list only have a 1 year limited warranty, and with 7 years you know that Cooper&Hunter stands by their unit. This unit vents from the side and has a low profile design if you don’t have much space or a window that will fit typical units.
The front has fan speed, temperature control or constant fan options. It’s super simple to read and use, so you won’t have any issue controlling this unit. With an average noise level of about 52 decibels, you won’t be bothered while enjoying the cold air coming from this unit, even when sleeping.
This model also has a heat pump which heats up to 13500 BTU. You won’t need to worry about installing another unit in your room/home, this unit does it all. The airflow up to 374 CFM is also a nice touch should you want to enjoy circulating but not cold air.
What I don’t like
This unit doesn’t come with a remote control and you’ll need to have a 230v outlet to use this unit. It will NOT fit into a 120v outlet so do be aware of that.
Verdict
While it doesn’t come with a remote, it does make up for it by having a heat pump as well as a 7-year warranty. It also will be low profile so you won’t need to have anything sticking out of any windows and being an eyesore.

- Remote: Included
What I like
With an SEER of 13, this window air conditioner is locked and loaded with energy-efficient cooling power. This unit is not a 15000 BTU unit but a 24500. You may be in the market for an upgrade, and for a bit more on the price you’ll be able to cool spaces of up to 1560 square feet down without an issue. That’s the size of an entire home!
Included is a full-featured remote control which will let you take advantage of 3 cooling and fan speeds as well as auto cool mode. You can customize your cooling how you like it with the auto cool mode. It comes with a check filter light which will make it easy to know when to wash your reusable air filter.
It comes with an installation kit as well to make installation a breeze. Reviewers mention they had an easy time mounting this unit with the mounting accessories included. If you’re worried about pets, this unit has an auto-restart mode which will kick in should the power go out.
This unit is a bit larger than other window air conditioners so make note of that if you’re limited on space. Reviewers mention that their entire house was able to be cooled down VS their other floor unit rated at 14000 BTUs.
What I don’t like
Some reviewers did mention that they had trouble after a year or two of this unit having issues. There are an equal amount of positive reviews though as well saying that their unit is one of the best ones they’ve come across in 40 years. This unit also plugs into a 230v outlet and not a 120v, which can be added cost.
Verdict
If you’re looking to upgrade your air conditioner and 15000 BTUs just won’t cut it, then this unit may be the choice for you out of air conditioners on this list.

What I like
While this isn’t a window air conditioner, it is a portable unit that has a cooling capacity of 775 square feet. The benefit of this model of other window air conditioners is that you can move it around. They do however have a cost, as they are less efficient than their window counterparts.

What I don’t like
The downfall of portable units is that they aren’t as efficient as window air conditioners. This can be a bummer if you’re expecting to save on your air conditioning bill at the end of the month.
Verdict
If you’re not in the mood to install window room air conditioners, then you’ll still be able to enjoy the easy installation of this portable model. Enjoy from sleep mode, energy saver mode, cool air, and much more.
Best 15000 BTU Window Air Conditioner FAQ
How many square feet will a 15000 BTU air conditioner cool?
15000 BTU air conditioners should cool down a 700-800 square foot space. Each model will have its own fan speeds and limitations depending on your location and how humid/hot it is. Remember these are perfect scenarios that manufacturers list, so your mileage may vary.
If you need to cool down an 800 square foot space, I would recommend going with a higher BTU window air conditioner so you won’t be maxing out your unit at full power.
How much electricity does a 15000 BTU air conditioner use?
Window units are rated to use between 500 to 1500 watts. Multiple reviewers have mentioned that their 15000 BTU units cost between $10-20 per month. Your costs will vary depending on where you live.
Is it cheaper to run a window air conditioner or central air?
Central air conditioners are going to be rated at much higher BTUs than even a 15000 BTU window air conditioner. This will lead to a higher energy bill, but central air conditioners are used to heat or cool the entire house rather than one room.
Can Window AC cool the entire house?
Window air conditioners are used to cool down a single room. Higher rated units can help cool down adjacent rooms and hallways, but don’t count on one window air conditioner to be able to cool down an entire house.
Is it OK to leave a window AC on all day?
Yes, it’s perfectly fine to leave your window AC on all day.
Final Thoughts
You won’t be disappointed if you decide to go with the hOmeLabs 15,000 BTU window air conditioner. You’ll also enjoy the Frigidaire FFRE1533U1 model as well if you decide to go with that choice.
