My previous window unit was a “cheapest of the cheap” model that was so loud I used to wake up with ringing in my ears. I looked up quiet models and purchased this one. The difference is night and day! I’ve been able to turn down the volume of my morning alarm, I fall asleep faster and stay asleep longer. I am beyond pleased with this purchase. 

I have seen reviews on other sites that say they run into issues a few months after purchase and I’m keeping my fingers crossed that it stays wonderfully quiet for years to come.
