** I’ll be adding #10 best Window Air Conditioners this summer. Stay tuned!

Best Window Air Conditioners – Overview:

Buying the right unit is not just picking the right size and the right power. Keeping an eye out for the additional features is also important and can reduce the cooling time and costs.

Having a remote control or a LED display indicating the cooling mode are just some of the features that can make your life easier. So, before getting yourself a window air conditioner, do a good research and find out what your needs are.

End of the year is approaching and temperatures are dropping, but depending where you live – some areas can still be wicked hot!

Window ACs are becoming a popular item this year w/ many new features rolled out – auto cooling, 5+ fan speeds, remote controls, temperature setting, etc.

If you’re still looking to buy one this year you’re going to buy one that’s durable and can last this summer and beyond. Window ACs are known to be durable lasting 3+ years.

I have owned my Frigidaire AC for 5-years and even though I need to clean the filter each summer it ran like a champ this entire summer (and it gets extremely hot in Brooklyn, New York)

Window AC units are also much cheaper than investing in a full HVAC system or spending hundreds on ductless AC (like the ones you see in bars and restaurants).
