How to Cool A Large Room & Open Living Spaces

Here at LivingDirect, we are proud to have one of the largest selections of window air conditioners online. Whether you need a small 5,000 BTU unit for your bedroom or a large unit designed for commercial purposes, we are confident that we have the best air conditioner to meet your specific cooling needs. To help get you started, you will see that on this page we are featuring only window air conditioners that have more than 12,000 BTU's.

Who Needs An Air Conditioner With More Than 12,000 BTU's?

These large air conditioning units are designed for homes and businesses that have sizeable open spaces that need to be kept at a comfortable temperature. In general, the larger the room, the higher the BTU rating will need to be for the AC unit to work in an efficient manner. However, if the ambient temperature of the room tends to be high due to sun exposure or heat from appliances, then smaller areas may need a window air conditioner with more BTU's.

Why You Should Consider A Window AC Unit

There are many benefits to using a window AC unit in your home or office. Many homeowners appreciate the user-friendly nature of window air conditioners. These units can generally be easily installed by the homeowner and finishing touches, such as adding weather stripping or caulking the outside of the window, can also be easy to complete. When it comes to large window air conditioners, however, you may need to do a bit of extra planning, such as preparing a 220-volt outlet. But overall, these units are all designed to have powerful cooling abilities that will ensure that you’re comfortable when outside temperatures are on the rise.

Another advantage of larger air conditioners is the overall energy efficiency of the units themselves. Whether it's a 12,000 BTU unit or 25,000 BTU unit, there are plenty of Energy Star air conditioners available for you to choose from. These units have all been tested and certified to help you slash the amount of energy you use, as well as save you lots of money over the course of using the unit.

What Size Air Conditioner Do I Need?

Before you buy an air conditioner, it's important to know the square footage of the room you intend to use it in. You don't need the exact measurements, but it's wise to have a general size in mind. As you can see from the general guidelines below, the amount of BTU's needed to efficiently cool your space will go up as the room grows larger.

  • 12,000 BTU = 450 to 550 sq.ft.
  • 14,000 BTU = 550 to 700 sq. ft.
  • 18,000 BTU = 700 to 1,000 sq. ft.
  • 21,000 BTU = 1,000 to 1,200 sq. ft.
  • 23,000 BTU = 1,200 to 1,400 sq. ft.
  • 24,000 BTU = 1,400 to 1,500 sq. ft.
  • 30,000 BTU = 1,500 to 2,000 sq. ft.
  • 34,000 BTU = 2,000 to 2,500 sq.ft.

If you're not sure about the size of your room or are worried about other factors causing the ambient temperature to rise, then it would be wise to buy a window AC unit with a slightly higher BTU capacity than is recommended in the chart above.

No matter how large or small the unit may be, to achieve the most efficient cooling from your window air conditioner, you need to consider three things — central placement, close proximity to a power source, and limited sun exposure.

Tips to Buying the Best Window Air Conditioner For You

Using a window air conditioner as an alternative to central air conditioning is not only a more efficient manner to cool your home, it's also a smart way to save money. With low purchase prices and nearly non-existent installation costs, this type of air conditioner will more than pay for itself over the course of its lifespan. This is especially true for window units that are designed to cool large rooms.

Compare the Features

Once you have a good idea of how many BTU's you will need, it's only a matter of choosing what features are important to you. From programmable timers to variable fan speeds to built-in air filters, the options to choose from are nearly endless. One feature we would suggest you consider, is a window unit that doubles as a heater. These units will give you the most bang for your buck, as you can use it to stay cool in the hot days of summer, but also use it for warmth during those cold winter nights.

Compare the Brands

With so many manufacturers out there, you will certainly have plenty of models and brands to choose from. We carry window air conditioners of all sizes from the most reputable manufacturers on the market, including LG, Friedrich and Koldfront.

No matter how large you are looking to go, we are confident that you will find the right window ac unit here. Please give us a call if you have any questions or would like some guidance on finding the right sized air conditioner for your home. We're here and ready to keep you cool.
