Use Cases
Sylvane offers AC window units that are strong enough to efficiently cool larger spaces or open floor plans with massive bedrooms or living areas within your home. If you are in an apartment or condominium, we offer AC units that are ideal for spaces without central AC. Home offices or studios should maintain comfort in rooms with high heat output from electronics by adding an AC window unit large enough to cool the space.
For commercial use, such as offices, shops, or break rooms that need quick, reliable cooling, a large window AC is necessary. If you have a room within your home or another space that doesn’t cool as well as other rooms, you might need supplemental cooling to add additional support to rooms underserved by central HVAC systems.

It also depends on the Combined Energy Efficiency Ratio, which accounts for both operating and standby power. Look for the Energy Star labels that indicate the most energy-efficient AC window units for large spaces.
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.
