How to Choose an 8000 BTU Air Conditioner

Be sure to review the qualities below if you are unsure about how to pick one of these top models. 

Portability

When it comes to purchasing an air conditioner, you should be sure to check how much it weighs, just in case you need to move it around from time to time.

Preferably, look for a model that weighs between 40 to 60 pounds.

Space

We know you would not want to purchase an air conditioner that occupies too much space in your room or office. Hence, it always advisable to check a unit’s dimensions; for instance, one with 14.4 x 17.3 x 11.1 inches would be a good fit for a small room.

Room Temperature

This an important aspect too; you obviously want a model that serves two masters at once. Buying an air conditioner that can be used in both cold and humid areas is the best idea since it is economical.

Energy Efficiency

It is advisable to look for a model that saves energy while running in order to avoid huge electricity bills. You could choose the one that meets the Energy Star requirement, as this will help you save 25-20 percent of energy monthly.

Ease of Use

When looking for an air conditioner, ensure you purchase one that has a remote control so that you can operate it easily.

Review

This Midea portable air conditioner is excellent for cooling small rooms so effectively that they’ll feel like iceboxes. There are several other modes also available, such as dehumidification, purification, and ventilation.

While there’s a setting for lowering moisture in the air, it’s so low that you won’t feel the effects in areas with high humidity. Furthermore, the instruction manual is slightly complicated, so you may need some help setting it up.

If you’d like to set a time for the device to start or stop, there’s a handy function that works for up to 24 hours. You can also choose to operate the air conditioner with a remote or via voice control.

Bottom Line

More and more air conditioners include other modes that help improve the air quality. You can reduce humidity for more effective cooling or eliminate those terrible dust particles or allergens.

If you don’t feel like standing up to get the remote, there’s a voice control app you can install to use on your phone. The installation kit and hose are other elements that also make your life easier.

How Do 8,000 BTU ACs Compare to Other Sizes?

You may be pricing around for the best air conditioners on the market and noticing a slight difference in cost between various sizes. While it may appear promising, there are some differences you should be aware of. Let’s compare the closest air conditioners to the 8,000 BTU.

8,000 vs 10,000 BTU Air Conditioner

The main elemental difference between these two sizes is how much space they can cool. The 8,000 BTU generally covers up to 250 sq. ft. while the 10,000 BTU goes up to 300. They can manage different sizes at the same cooling rate, so it’s best to measure your space first.

The larger air conditioner is also able to handle higher temperatures and humidity levels. The downside is that it’s also usually heavier to install or move around. You’ll find more functions and power at your disposal, but it will consume more power.

6,000 BTU vs 8,000 BTU Air Conditioner

A 6,000 BTU almost has the same performance, covering rooms between 150 and 200 sq. ft. There’s such a minor difference that’s it’s almost negligible. However, if you add factors like humidity, air circulation, and dust, it’s better to opt for the 8,000 BTU.

You’ll also need to assess how much temperature each size can handle. The 8,000 BTU might use a little more electricity, but it may be worth it in warmer climates.

Types of ACs With 8,000 BTUs

There’s isn’t only one type of air conditioner. If you look up 8,000 BTU ACs, you’ll see a variety available on the market. Here are a few examples of what you’ll find, each one catering to a different situation. 

Window 8,000 BTU AC

These air conditioners are ideal if you’re not worried about blocking natural air and light. You can install them in any windows in your home and are considered one of the most energy-efficient types. They remove hot air from your room and eject them outside with minimal effort.

Portable 8,000 BTU AC

Many people that live in apartments or travel in motorhomes prefer portable air conditioners. They’ll either have a water bucket or drainage pipe for the condensation. You even find ones that have internal evaporators to exhaust the air out the windows.

Mini Split 8,000 BTU AC

Another handy option is the mini-split air conditioner. Instead of taking up window or floor space, you’ll install one component on your inside wall and the other outside. You’ll receive excellent cooling while eliminating condensation and noise levels from the interior.

Smart 8,000 BTU AC

Some manufacturers go the extra mile and install smart components in air conditioners. You can choose different control methods, such as remote, voice, and Wi-Fi. There are unique timers and various modes that you can adjust yourself or let the device decide for you via sensors and thermostats.

Top Brands With 8,000 BTU Air Conditioners

As you’ve seen from our review of the best 8,000 BTU air conditioners, several manufacturers produce various devices to different specifications. While it’s a tough call dividing the top ones from the worst, we’ve selected three that we felt you should have a look at.

LG Electronics

LG started in 1968 as GoldStar, putting its feet in the HVAC industry with the first residential air conditioner in Korea. In 1970, it developed the initial chillers for industrial buildings, expanding its reach in other countries. It also produces several home appliances and electronic devices.

It’s made a name for itself with inverter air conditioners, considered by many to be the most advanced in the world. LG also has a reputation for manufacturing the most energy-efficient devices.

Midea

The Midea Group goes as far back as 1968 with the main headquarters in China. It specializes in home appliances and HVAC systems, with a few 8,000 BTU devices in the mix. Most of them are mini-split or portable air conditioners.

Today, it has over 100,000 workers in over 200 regions. Its air conditioners have an outstanding reputation, while you’ll have better luck with its customer servers as opposed to those of its distributor

Honeywell

If you’re looking for a household name that’s been around for decades, Honeywell has an excellent reputation for its massive catalog of HVAC products. It includes purifiers, dehumidifiers, humidifiers, air conditioners, chillers, and evaporators.

The brand has won several awards and massive contracts since its inception in 1906.

It includes purifiers, dehumidifiers, humidifiers, air conditioners, chillers, and evaporators. One of its first achievements was developing the first coal-furnace thermostat in 1885 when it was called Butz Thermo-Electric Regulator Company.

Who Should Not Buy an 8,000 BTU AC?

Now that we’ve shown you the benefits of buying these devices, there are situations where you might not need an 8,000 BTU. We’re not trying to dissuade you from getting one, but it’s better if you choose the right air conditioner for the occasion. Let’s look at when you should not buy one of these units.

Excessive Heat or Humidity

An 8,000 BTU AC can only handle so much heat and humidity. Each device is manufactured differently, so it’s best that you read the specifications.

If you live in an area with high temperatures, you may want to look at a more powerful unit. If there’s too much humidity, try aiming for a dehumidifier instead of an air conditioner.

Spaces Under 200 or Over 250 Sq. Ft.

When you buy an air conditioner, the BTU number is an indication of its cooling capacity. The 8,000 BTU can manage anywhere between 200 and 250 sq. ft.

While you may find devices that can cool larger spaces, it’s better not to push your luck. More extensive rooms need a larger BTU. Don’t overwork your air conditioner and lower its lifespan in the process.

Dusty Regions

One element you don’t want to introduce to an air conditioner is dust and allergens. While some may have washable filters that you can clean, they’re not equipped for excessive amounts of air pollutants. In these situations, you’ll want to aim for a purifier instead.

Pros and Cons of 8000-BTU Air Conditioners 

8000-BTU air conditioners have both their benefits and drawbacks. Here are a few listed below. 

Pros

Let’s first take a look at the positive aspects of investing in such a unit.

Affordable

Window units generally cost lower than portable air conditioners and come in a range of different prices. 

High BTU

BTU is a way to measure energy, and a high BTU indicates a powerful air conditioning system. It denotes that the air conditioning unit has a better capacity to cool the room, and an 8000-BTU air conditioner can cool a large space. 

Space

An 8000-BTU air conditioner can easily cool an area of about 300 square feet and more in a short amount of time.

Cons

Meanwhile, the drawbacks include:

Difficult to Setup

Window air conditioners are quite heavy and can be difficult to lift up, especially with no help. They can also block sunlight, which is not a problem with portable air conditioners.

Cycling

A greater BTU means that the air conditioner will cycle off and on frequently. This will result in the compressor overworking itself and can shorten the unit’s lifespan.  

Conclusion

We would like to advise you to take all these aspects into consideration when purchasing an air conditioner since they are all vital.

The above-mentioned air conditioners may differ in a few aspects; for instance, some may have energy saving modes whereas others do not but they all work efficiently. Therefore, you should choose the one that you find the most convenient.

People Also Ask

We would like to answer some questions that we often get from people in order to help you choose the best air conditioner.

What Does 8,000 BTU Mean?

The British Thermal Unit (BTU) measures the ability of an air conditioner to cool space within a given amount of time. The number is an indication of how much space it can comfortably cover. For instance, an 8,000 BTU can cool a room of between 200 and 250 sq. ft.

Is 8,000 BTU Enough For a Small Apartment?

Yes, it is. It can cool up to 250 sq. ft, which is generally the size of a small apartment. If you’re aiming to cover a bedroom that’s less than 200 sq. ft., you might want to look into 5,000 or 6,000 BTU devices.

What Happens If Your BTUs Are Too High?

If you have an air conditioner that’s too powerful for your room, it’ll feel too cold and you won’t be able to warm it up again unless you switch off the device. You’re also using more electricity than is needed for your small space.

Is It Cheaper To Run a Portable Air Conditioner?

If you’re comparing it to the window and central air conditioners, then it is. You can move it to the room that needs attention instead of cooling the entire house or installing more than one unit.

Are 8000 BTUs Enough For a Bedroom?

This depends on the the size of your bedroom. An 8000-BTU air conditioner works well in about 350 square feet or so; hence if you try to use it for a larger area, it might not cool the room quickly or well. Moreover, a large BTU can have its drawbacks, as elaborated above. 

How Much Does an 8000-BTU Air Conditioner Cost? 

An 8000-BTU air conditioner can cost anywhere from as low as about $250 to as high as approximately $1000.

How Much Does it Cost to Run an 8000-BTU Air Conditioner?  

There is a formula for calculating the cost. The first step is to determine the number of amperes the unit draws in. Multiply this by the voltage of your air conditioner to get the wattage it uses.

You’ll need your previous electricity bill to estimate how much the chargers per hour are depending upon your utility company. Now multiply this amount by the kilowatt-hour sum, and you’ll get an approximate of the window unit cost per hour to run. 

For example, if your air conditioner runs for eight hours daily, and seven months a year, that means you’d pay about $134.40 annually. You can also use our calculator that helps you determine how much electricity an AC unit uses if you want more data.

How Many Amps Does an 8000 BTU Air Conditioner Draw?  

An 8000 BTU conditioner draws 10 Amps

What Size Room Will an 8000 BTU Air Conditioner Cool?

It comfortably covers a room of up to 350 square feet.

How Many Watts is an 8000 BTU Air Conditioner?

It has a maximum of 740 watts.
