Key Takeaways

CNET's key takeaways

The Windmill AC normally starts at $339 for 6,000 BTUs, but you can find it on sale right now at Windmill's website Amazon

Not only is the Windmill AC the easiest unit I've ever installed, it's the only AC unit I've tried that effectively kept my older and not well-insulated home cool during heat waves.

Bonus: It's actually stylish. (I still would have paid for an ugly one that works.)

There are a lot of things I love about living in an older home -- my 100-year-old rental has original 1920s art deco tile, tall ceilings, and a lot more character than you might find in a newly constructed house. One thing it doesn't have? Central air conditioning.

With record-breaking heat waves regularly hitting in my area, I needed to find window ACs that could cool my poorly insulated 2,500 square foot home.

I hunted for the right one for years. Every summer I'd buy and test out new window air conditioners, only to feel frustrated by how poorly they worked. I'd sell them at the end of the season, and restart the cycle again the following year.

Finally, after years of sweating through sweltering three-digit temperatures and overbearing humidity, I found it: the Windmill WhisperTech window air conditioner. This innovative powerhouse was so effective at cooling my oversized master bedroom, that I eventually bought two more. These three AC units effectively cool my 2,500-square-foot Philadelphia row home even during intense heat waves. And they look great while they do it.

The Windmill AC isn't the cheapest option on the market, but for me, it was well worth every cent. If you're also fed up with sweating indoors, here's why you need to try this game-changing AC.

I've had the 12,000 BTU Windmill WhisperTech air conditioner for three years, and it keeps our master bedroom comfortable during intense temperatures. (It's stylish, too!) Courtney Johnston/CNET
