As the mercury rises, it’s important to get your home ready for the hot weather. While there are several DIY ideas to cool your home, choosing a reliable window air conditioner can help keep you and your family comfortable.
However, you must always determine the size of your room before choosing a window-mounted air conditioner. If your space is approximately 450 to 550 square feet, you should look for the best 12000 BTU window air conditioner.
I recommend using window units because they are less expensive than central units, easy to install, and energy-efficient for small, confined spaces.
The 12000 BTU air conditioners I’ve reviewed below have the same cooling power, but some are more popular and have several customer ratings and reviews than others.
Top 5 Best 12000 BTU Window Air Conditioners
Is a 12,000 BTU AC Good?
Yes! A 12,000 BTU air conditioner is good enough if you only want to cool a room of between 450 to 550 square feet. The good thing about using this air conditioner is that it’s cheap, efficient, and portable. It fits into the category of some of the most portable air conditioners in the market.
When it comes to efficiency, you can fully count on it since it doesn’t consume a lot of electricity. Therefore, it can help you save energy costs. However, before buying this air conditioner, you need to ensure you choose one with a high energy-efficiency rating (EER).

Here are some of the pros and cons of a 12,000 BTU air conditioner.
Pros
- Portable
- Energy-efficient
- Easy to install
- Easy to use
- Cheap to maintain
Cons
- It can be noisy
- Limited to cooling up to 550 sq. ft of space
If you have a slightly larger room you may want to go for a 15000 BTU window unit or consider some of the best models for large rooms.
How Many Square Feet will a 12,000 BTU Air Conditioner Cool?
A 12,000 BTU air conditioner can comfortably cool a room of maximum size 550 sq. ft. If you happen to have a larger room than that and intend to use a 12,000 BTU AC, note that it might not be as effective as you would want. The main reason for this is because it may have to strain too much to get the job done.
Every air conditioner is designed with a BTU count that can cool a specific size of room/space. Therefore, this is why it’s important to first compare your room with the AC you want to buy to avoid regretting it.
That means with this air conditioner, you have the convenience of even carrying it and using it anywhere, such as your office, camping tent, or bedroom.
If you live in an apartment with only a few windows, you can use a 12,000 BTU air conditioner to keep you cool during the summer season.
How Much Does It Cost to Run a 12,000 BTU Window Air Conditioner?
A 12,000 BTU window air conditioner can use about 15 amps of electricity when it’s running from a 125V outlet. When you calculate this figure, it gives you the result of approximately 1.8 kWh. If you run the air conditioner for an average of 8 hours per day, it gives you a daily cost of $1.2.
Therefore, the cost of running just one air conditioner 8 hours per day translates to approximately $36 per month. But it would help if you kept in mind that it’s only for one room in your house, and you would need about 2 or 3 window air conditioners to have the best cooling comfort in your home.
This, therefore, translates to more monthly costs of running window air conditioners in your home than you would incur running a central air conditioner. Another disadvantage of window air conditioners is that it’s impossible to hook them to a thermostat the way you would with a central air conditioner. That means you will need to monitor them closely.
How Many Amps Does a 12,000 BTU Air Conditioner Draw?
A 12,000 BTU air conditioner draws approximately 5 to 6 amps. However, this will highly depend on the energy-efficiency of your air conditioner. You should also note that it can also draw 15 amps at 240 volts.
To know the number of amps an air conditioner uses, here is a simple calculation you can do:
12000 BTU rating = 1200 watts = 1.2 kW
Therefore, the inverter AC for the current will be:
1200/220 = 5.5 amps
When you consider the power factor, which is 0.8, the maximum current of the 12,000 BTU air conditioner will be:
5.5 / 0.8 = 6.8 amps
How Much Electricity Does a 12,000 BTU Air Conditioner Use?
We usually buy an air conditioner based on its BTU number and the size of the space you want to cool. However, to correctly estimate the electricity costs an air conditioner incurs, you need to know how many watts it uses. For instance, the average 5,000 BTU air conditioner uses approximately 500W of energy when you’re using it at full capacity.
To know how many watts your air conditioner uses, you can check on the specification sheet for watts, check the specification sheet for amperes and volts, or use the BTU and EER rating to calculate the amount of power it uses.
Here’s an example equation:
12,000 BTU / 10 EER = 1200W
Note that if you want to estimate the number of watts an air conditioner uses, you need to take the BTU number then divide it by 10. Therefore, a 12,000 BTU air conditioner with an EER rating of 8 can use between 100 to 1500W. Having an AC with a high energy efficiency rating reduces your energy costs.
12,000 BTU Window Air Conditioner vs. 12,000 BTU Portable Air Conditioner
Window air conditioners tend to differ from portable air conditioners. A window AC unit is usually stored in your living space, helping to reduce clutter in your home.
Window ACs also use less energy compared to portable air conditioners. However, when buying a window air conditioner, it’s important to check its BTU rating and ensure it is efficient enough to save energy costs.
Window ACs can also be installed through the wall, which means it doesn’t require an actual window. On the other hand, portable air conditioners are flexible, easy to install, and mobile, which means you can move them around.
Both window ACs and portable ACs have their benefits, but it will depend on the one you feel is suitable for your needs.
5 Things to Consider when Buying a Window Air Conditioner
It’s important to check several features before buying a window air conditioner.
These include:
- Size: Choose a window air conditioner with a convenient BTU number that can comfortably cool your space. A higher BTU air conditioner is recommended for large rooms while a lower BTU rating for smaller rooms.
- Energy-efficiency:This is the most important factor to consider if you want to save energy costs. You can check if the window air conditioner has an energy star rating or an AC with a higher EER rating.
- Installation:You can install most window AC models in a customized wall due to their design. Therefore, it’s important to check whether the window AC you want to buy is easy to install to save you all the hassle.
- Maintenance:Window air conditioners require the best maintenance, which means you need to ensure you buy an AC that’s easy to maintain.
- Electrical requirements– Most of the window air conditioners available on the market use approximately 115 to 220 volts circuits. That means you need to check if you have an electrical system that fits into the air conditioner you want to buy.
