Window Air Conditioners

What Is a Window Air Conditioner?

For many, investing in a whole-home HVAC system is unnecessarily time-consuming and unnecessarily costly. What if there was a way to cool one specific room at a fraction of the cost?

There is: air conditioner window units. These self-contained AC units fit snugly into any standard window opening. From there, they remove heat and humidity through a refrigerant system—clean, cool air without the heavy cost of a larger AC system.

Window air conditioners are super simple to install and operate. Most models feature multiple fan speeds, programmable timers, remote controls, and adjustable louvers to direct airflow where you need it. Some units even include built-in heating, providing year-round comfort in a single device!

Why Choose a Window Air Conditioner?

• Affordability: A window air conditioner costs much less than a traditional (or even ductless) AC system—in some cases, less than half the price!
• Easy Installation: Quick and straightforward to get up and running—perfect for renters, DIYers, or temporary setups.
• Versatile: Sylvane carries models that fit a variety of window styles, including small, medium, and large windows.
• Energy Efficiency: The window air conditioner unit cools only a single room, so you’re saving precious dollars on your monthly bills.

Window AC FAQs

How do I know what BTU rating I need?

BTUs represent power, so it generally depends on the room size. A 5,000–8,000 BTU window unit air conditioner would suit a smaller room of about 100–300 sq. ft., for example. Use our
Window Air Conditioner Buying Guide for detailed sizing tips.

Will it fit in my window? What window size is required?

Simply measure your window before buying. When you browse our selection, you’ll see that each model lists the minimum and maximum window width and height required.

Can I install window air conditioners myself?

Yes! Most units are designed for easy DIY installation with included mounting kits. Just make sure to follow the manufacturer’s guide carefully!

Are these units loud?

It depends on the model. You can get an especially quiet window air conditioner if that’s what matters to you.

What’s the difference between a standard and smart window AC?

Standard models offer manual or remote control. Smart models add Wi-Fi connectivity so you can access controls from, say, your phone.

How much electricity will it use?

It depends on the model. However, window air conditioner units are generally very efficient. Look for Energy Star-certified models to save on electricity.

Do I need to remove it in the winter?

We recommend removing, or at least covering, your window air conditioner unit in the off-season to protect it from the elements and improve insulation.
