Best 8,000 – 10,000 BTU Air Conditioners: Portable, Window, Room

I’ve tackled the best 5,000 – 6,000 BTU air conditioners previously. It is the best pick for rooms with a size of 100-300 square feet. Similar to shopping for other home appliances, you should consider the cost-efficiency of each product. It doesn’t matter whether you’re looking for a lawn tractor or utility sink. We consider the durability and cost of appliances most of the time before buying them. This should also be applied when shopping.

To save you from brainstorming about what makes one a good buy, I’ll carry you through the factors that you must take note of. Some examples of these factors are the type and BTU. How small is the unit? Quietness and ease of installation are also important factors. I hope that by the end of this blog post, you’d already have a good pick of the brand size. You’ll have found the best 8,000 – 10,000 BTU air conditioner.

8000 BTU air conditioner

Things to consider before

The limitations of your space are probably the first thing that you should consider when you’re looking for the best option for your room. Having two or more windows is preferable when you’re opting to buy a window type. It will render one side of the window unusable after installation. You should also consider if you need one unit that you can easily transfer from one room to another. Maybe you prefer a more permanent fixture like a wall-mount option.

Of course, the size of the room must be taken into consideration because it is the deciding factor in picking the right BTU. If the BTU isn’t high enough, the unit may not be able to cool down the whole room to your preferred temperature. And if you purchase a too powerful unit, you’ll just be wasting energy and ramping up your electricity bill.

We’ll delve into the common types of units first, so you can decide which one will suit your needs.

10,000 BTU air conditioners


Not everyone has the luxury of getting the room that they want. We all know that large windows and spacious bedrooms hike up the price of rooms, especially rentals. Without a large and sturdy window, you can’t opt for a window option. And without a window, you can’t opt for a split one that comes with a window kit for drainage. This is when a portable one comes in handy.

PACs came into the market when manufacturers recognized the need for a good one that could be used in rooms without windows. They became a hit due to their relatively low price and flexible installation options that other options cannot offer. They boast a compact, self-contained system. They can effectively cool small rooms where through-the-wall options are too much to put up with. It may be due to space limitations or energy consumption. The venting system is fairly easy to install, which is another charm of these products.

It sits on the floor, but some models have handles and wheels for better movement. With these added features, you can easily move the unit from one window to another. Some brands even came up with mini-sized options that are more lightweight and compact, perfect for small rooms.

There are also different types in terms of water draining. Standard ones require manual water removal. You have to periodically empty a container in the unit that collects moisture. Other models have what you call a gravity drain and condensate pump. It involves attaching a draining hose to the unit and directing the other end of the hose outside or into a drain. Advanced models now have self-evaporative features. The PAC unit evaporates moisture out of the same exhaust hose that the venting system uses .

AC unit being installed

Today, numerous brands have transformed some of their powerful units into portable ones. A lot of PACs can now cool down larger rooms. Some examples are vertical models that can cool large rooms. BTU range of such units ranges from 6,000 to 20,000 for residential units. The units for commercial or industrial settings have 12,000-40,000 BTU.


Window ones are probably one of the most common types that you’d spot at homes or rental spaces. These are cheaper and easier to install than other bigger options and usually do not require extra installation fees. They are a popular choice for rental spaces because they are more of a temporary fixture than a permanent one. You don’t have to cut a rectangular hole through the wall to fit this type in your room.

The only thing that a window unit requires is a decently-sized sturdy window. It needs to accommodate the unit—installation is quite a breeze after that. Since these units are meant to fit within the boundaries of a window, they are relatively lightweight and compact. You must have an accurate measurement of the unit. Compare it with your window’s measurement before purchasing it. It’s better to leave a few centimeters of allowance than buy a unit that won’t fit. The unit will be screwed down to the appropriate location at your window, and the gaps around it will be sealed. The only downside of using a window option is that the window it’s situated in becomes pretty much unusable after the unit has been installed. It can block light and remove the option of opening a window because it’s screwed shut.

It’s also important to choose a window with a nearby electrical outlet to power it up. If you only have one window for your unit and it’s too far from the outlet, you can go ahead and buy an extension cord. Choosing the right extension cord for appliances that use up a lot of power is vital to avoid accidents.

Suppose you plan on buying a circuit breaker or fuse for your appliances. You need to find out which wire size is appropriate to make sure that it can handle the electrical current. These guide articles on amp wire sizes for 20-60 Amp extension cords and 70-600 Amp extension cords will help you pick. Avoid accidental fires or appliance failures. If you’re planning on buying an RV roof option instead, make sure to know exactly how many amps your RV can handle. Avoid any machine failures.

Through the wall

Wall-mounted models are similar to window ones. These two are composed of one big unit with their vent facing outside and their fans, which blows cool air and face inwards. Unlike PACs, they don’t need extra window kits for ventilation or water drainage. Wall-mounted ones are heavier and occasionally bigger than window ones. This is why most through-the-wall units can’t be interchanged with window units—window frames are not as sturdy as concrete walls.

The second notable difference between wall-mounted and window models is the placement of vents. Window ones have vents at the sides that expel warm air. Wall-mounted ones only have vents at the back. This is why wall-mounted can be lined up flushed with the exterior wall, with little to no hanging parts. Window options only hang out from the window so that the side vents can have some space. Through the wall, ones are usually cheaper than split options and central conditioning. It’s a great choice for cooling down one small to a large room.

Suppose you’re a handyman who’s planning to move or reinstall a window or through-the-wall unit by yourself. You might want to check out these products that can make your life a whole lot easier. Engine-driven welders and UV light sanitizers both perform important functions. Or simply check out this conversion chart from SAE to metric.

What to look for

With so many options on the market, it can get hard to keep track of which is the best option. To help you out, here’s a quick list of some of the noteworthy features that you should look out for:

What to look for
Level of noiseAir qualityWarranty
MaintenanceEase of cleaningCooling capacity
Energy Efficiency  


If you’re sensitive to sounds and you plan to put it in your bedroom or office, opt for the quietest model that you can find. A decibel range of 50-60 dB would be the perfect choice for you.

You can also opt for models with a 60-80 dB range. Most of these models only get noisy when they’re running at 100% capacity. They are generally quiet when running only at 60% capacity.

Air quality

If you’re suffering from asthma or allergic rhinitis, you have to pick one that can give you clean air. Pick a unit that has a good filtering performance, equipped with a high-quality filter. It should be easy to replace or clean. A dirty filter is a prerequisite for poor air quality and filtering performance. Some models have HEPA filters, and some even have auto-cleaning filters.

Maintenance / Cleaning

Pick a unit that has the least tedious upkeep. They are easy to clean, will last longer, and will require less costly maintenance. Some brands offer self-cleaning units with filter indicators, which is very useful if you’re forgetful about routine cleaning.

Energy efficiency

Having one is both a luxury and a necessity nowadays. With worsening climates and skyrocketing energy rates, they’re great. It’s vital to pick an efficient and energy-saving option. Some brands consume more energy than others despite having the same power capacity.

Check whether it is Energy Star Qualified. It means they’re proven to be energy-efficient. Opt for the one that has a higher star rating. The higher the rating, the more energy-efficient it is.


When it comes to electrical appliances, it’s important to choose a brand that offers a long warranty. Repairs can get pretty expensive. Also, try to look for a brand that offers free returns within 30 days.

Cooling capacity

Room size of an 8,000 & 10,000 BTU unit & how much it powers

The cooling power of these products is usually expressed in how big the room it can cool down. They have what you call a BTU. Depending on this and the size of your room, you can properly choose the right one for you. So, what’s BTU?

  • British Thermal Units (BTU) is an international measure of energy. It describes the amount of energy that’s needed to increase the temperature of 1 lb of water by 1°F.
  • 1 BTU = energy required to increase the temperature of 1 lb of water to 1°F

They work by condensing air and evaporating liquid to remove hot air and release cool air. It is why BTU matters. A larger area would contain larger amounts of hot air that needs cooling. You’d need one with a higher BTU so it can effectively lower the temperature of the area. The bigger the room, the higher it needs to be. As a rule of thumb, a unit would need 20 BTU to cool down the air in one square foot of space.

However, too much cooling power can also harm your wallet and the environment. Opting for one with a BTU that’s way higher than recommended for your room leads to waste. Suppose you buy an 8,000 BTU option for a mere 250 sq. ft. room. It will just undergo each cycle too quickly, wasting energy and hiking up your bills astronomically.

One with a range of 8,000 – 10,000 BTU would be the perfect choice for a room with a size of 300-450 square foot area. This is a good unit for living rooms and bedrooms. Here’s a chart from Energy Star that you can use as a cheat sheet as you shop:

However, some factors may also affect the cooling power. The BTU per hr requirement of a certain area must be adjusted depending on the following:

  • amount of light the room receives
  • crowded spaces
  • appliance load or type

When it comes to RVs or campers, the BTU requirement is usually higher. That is, relative to what you’d need in your house. It’s due to the factors above. An RV with an area of 300 square feet will need a 10,000 BTU RV model. It is usually a unit that can cool a standard room with a size of 450 square feet. To know the specific increase or decrease needed per factor, consult with the provider.

Brands with the best 8,000-10,000 BTU options

There are models on the market that have similar specs but differ in prices. Most of the time, the brand of the unit is what’s affecting the cost. To help you pick the most suited AC unit for you, I’ll be outlining the top-rated 8,000-10,000 BTU options. Use them to cool a 300-450 sq. ft. area room effectively.
