How Many Square Feet will a 15,000 BTU Air Conditioner Cool?
A 15,000 BTU air conditioner can comfortably cool a room of 650 to 750 square feet. To fully understand the ideal air conditioner for your room, you have to measure it and determine its square footage, and then select an AC effective enough for it.
A surprising fact you should know is that an air conditioner requires 20 BTUs for every square foot of your room. Depending on your room size, the ceiling height, and many other conditions, you have to calculate the number of BTUs your air conditioner will need to be effective enough.
There are several online tools you can use to determine the BTU number you need in an air conditioner according to the space you need to be cooled. It’s always recommended to purchase an AC that is a little bigger than the recommended size for your room.
The reason for this is because larger window AC units will be effective enough and won’t strain as much to cool the room. Most air conditioners don’t last long because when the room they are cooling becomes too hot, they have to work too hard to cool it. Putting this strain on an air conditioner makes get damaged faster.

How Much Does It Cost to Run a 15,000 BTU Window Air Conditioner?
Before you know how much it costs to run a 15,000 BTU window air conditioner, we’ll first understand how much it costs to run an AC per hour. Below is the formula to calculate this.
First, you have to find the maximum power of the air conditioner measured in Watts. This information is available in the specifications of all air conditioners. The second step is to determine the price of electricity in your area. This is calculated by cost per kWh.
Here is the equation:
Cost per hour = AC power (W) * electricity cost per kWh divided by 1,000
The cost of running a 15,000 BTU air conditioner is $0.20 per hour. Assuming you run your AC for 8 hours, the cost would be $48 per month. That’s an average cost of $576 per year or higher depending on how you use your air conditioner.
If you want to reduce your cost of running an air conditioner, here are crucial tips to consider:
- Check the EER, SEER, or CEER ratings of an air conditioner before you buy it. If it happens to have a higher rating, that will be suitable to help reduce your electricity costs.
- Minimize the number of hours you use your air conditioners. It’s an obvious fact that running your AC for many hours or even 24/7 can increase your electricity bills. Therefore, you can try to reduce the hours you use your AC to lower these costs.
Things to Consider when Choosing a Window Air Conditioner
Buying a window air conditioner requires the utmost scrutiny. That means you have to thoroughly check the AC you want to buy, ensure it the right BTU number for your space, it has a perfect size, and one with ideal features for your needs.
Here are some important factors to consider before choosing a window air conditioner.
Consider the power of a window air conditioner first before you buy it. The power of an air conditioner is measured in BTU. If an air conditioner has a high BTU, then it means it’s powerful enough to cool a small space comfortably without straining. This will help you determine the right size for the room you want to cool.
If you live in an area that experiences high temperatures of more than 100 degrees, you’re better off having an AC with a higher BTU rating.
Window air conditioners vary in price depending on the size, quality, and brand. Most of the cheap window air conditioners only have basic features and can cool small spaces. Expensive AC units are the ones that can cool large rooms, and they also included excellent features.
Aside from just the upfront cost of the air conditioner you want to buy, it’s also important to consider the energy costs you will incur from using it.
Type of Window
Window air conditioners usually need to be used on windows. Therefore, before you buy an air conditioner, you need to have a specific window in mind.
There is the option of installing your window AC through the wall instead of a window, although this involves going through a complex process and you also have to make sure you buy an AC unit model that supports the through-the-wall installation.
It’s essential to note that air conditioners consume plenty of energy. This is a proven fact, regardless of the type of AC you decide to buy. Another unfortunate fact is that window air conditioners are not as energy-efficient as one would expect.
Therefore, to try and minimize energy costs, you can check the energy star certification of an AC you want to buy, or make sure you buy one with a higher EER rating.
You also have to ensure you invest in a window air conditioner that will serve you for a longer period. For this, you can buy from reputable brands with good reviews from customers about the durability of their products.
Fortunately, most window air conditioners have a warranty and this enables you to have peace of mind for at least one or two years.
Air Conditioning Mistakes to Avoid in Summer
Here are air conditioning mistakes that you should avoid doing this summer.
- Setting your AC thermostat too low – This doesn’t help to cool your home faster as you would expect, but only put unnecessary strain on your air conditioner.
- Using a wrong-sized air conditioner – Make sure you choose a well-sized AC depending on the size of the space you want to cool, to help you avoid wasting energy.
- Installing your AC unit in direct sunlight can negatively affect it.
- Avoiding routine maintenance or tune-ups of your air conditioner. This will result in higher repair costs later on when the damages become too much.
- Forgetting to change the air filters. This will jeopardize the performance of your air conditioner.
