Best 8000 BTU Window Air Conditioners


Is 8000 BTU Air Conditioner Good?

Yes! An 8000 BTU air conditioner is good but only for a room of maximum size 350 square feet. Suppose you place this AC in a larger room than that, it might not be effective.

Another thing that makes this air conditioner suitable is its portability and energy-efficiency. It can help you save on electricity costs, and carrying it wherever you’re going isn’t such a hassle. Below are its pros and cons.


  • Portable
  • Cools rooms of size 350 square feet
  • Budget-friendly
  • Easy to install


  • Noisy 
  • Consumes high energy
  • Produces hot air

How Big of a Room will an 8000 BTU Cool?

It is essential to note that having an air conditioner with a large BTU means you can use it in a large room. An 8000 BTU air conditioner can cool a room of 350 square feet, which is better than a 5000 BTU air conditioner.

If you happen to have a larger room than the mentioned size, this air conditioner won’t be as effective as you want. Therefore, that’s one of its drawdowns that you need to keep in mind. 

8000 vs. 10,000 BTU Air Conditioner

The British Thermal Unit (BTU) is the amount of heat needed to raise one pound of water temperature, at or nearly 39.2 degrees Fahrenheit by one degree Fahrenheit. Therefore, a 10,000 BTU air conditioner can cool a larger room than an 8000 BTU AC. 

A 10,000 BTU air conditioner cools a large room faster than the 8000 BTU air conditioner. That means if you were to choose between either of them, the 10,000 BTU AC could be an excellent option to consider. 

To clarify the difference, an 8000 BTU air conditioner can cool a room of maximum size 350 sq. ft, while a 10,000 BTU air conditioner can cool a room of maximum size 450 sq. ft.

Is 8000 BTU Enough for a Bedroom?

Yes! An 8000 BTU air conditioner is suitable for a bedroom. You need to know that an AC is suitable for a bedroom provided the room is not too large for the air conditioner to be rendered ineffective.

If your room is in size range of 100 to 350 square feet, then an 8000 BTU air conditioner is a superb option to use. This AC can perfectly cool rooms within that size range, but it’s only limited to that. If your bedroom is larger, you would need to consider an AC with a larger BTU number.

How Much Does an 8000 BTU Air Conditioner Cost?

The price of air conditioners varies from one brand to another. Therefore, it may be hard to know how much an air conditioner costs unless you conduct proper research. 

From what we’ve gathered so far from the market, we can say that an 8000 BTU air conditioner can cost between $250 on the low end to $350 on the high end. It all comes down to the features, efficiency, and brand pricing of the air conditioner.

How Much Electricity Does an 8000 BTU Air Conditioner Use?

An 8000 BTU air conditioner consumes more electricity than a 5000 or 6000 BTU air conditioner. The average cost of using an 8000 BTU air conditioner is $0.11 per hour, which means if you run it for 8 hours a day can amount to $26.4 per month in electricity costs.

The best way to minimize the air conditioning electricity costs is to use it a few hours a day, especially only when you need it most, instead of letting it run the entire day or 24/7.

How Many Watts Does an 8000 BTU Air Conditioner Use?

An 8000 BTU air conditioner uses approximately 667W to 1000W of electricity. This range is a bit higher than the one used by the 5000 or 6000 BTU air conditioners. However, this is mainly because the 8000 BTU AC can cool larger rooms than the 5000 or 6000 BTU air conditioners.

How Many Amps Does an 8000 BTU Air Conditioner Use?

The 8000 BTU air conditioner uses between 5.8 and 8.7 amps. To calculate the number of amps an air conditioner uses, you have to change the BTU to electrical power in watts and then change the watts to electrical current in amps. 

Here are simple equations to properly do this:

BTU = EER divided by the electrical power in watts

Once you’ve gotten the results, the next equation will be:

P (watts) = V (Volts) * I (Amps)

To find out how many amps an air conditioner needs, below is the equation:

I (Amps) = air conditioner capacity in BTU divided by (EER * V) 

Can You Use a Window Air Conditioner Inside?

No, it’s not recommended to use a window air conditioner inside. Just as their name states, a window air conditioner is specially designed to use in a window and not inside. Running a window AC inside a room will only heat it and reduce humidity. Since a window AC unit is an air-to-air type of air conditioner, it cannot be entirely used in a room.

Can You Run a Window Air Conditioner without a Window?

No. Window air conditioners are only designed to work mounted on a window. They remove warm air and water as the byproduct of the cooling process, which means there isn’t any way of redirecting these things if you try to use this AC unit outside a window.

Can You Leave a Window Air Conditioner on 24/7?

Yes! You can leave your window air conditioner running 24/7 since it won’t cause any harm other than hiking your electricity bill. Some experts say that it’s okay to run an air conditioner 24/7, but the drawdown of this is that it puts too much strain on it, which is not recommended. Or you can just pick the low-wattage air conditioners.

The best option is to avoid running your AC 24/7 because it ends up damaging it faster than running it for only a few hours a day. If the summer weather is too hot even during the night, consider the alternative of using a fan or dehumidifier instead of fully relying on your AC to cool the room.
