My central ac system died and needed complete replacement after over 30 years of service.  Of course, it quit during the hottest summer on record. I bought this window unit to keep the house cool until I can get the main system fixed... and I'm happy to say it's done a great job keeping things comfortable. I especially appreciate that this model can be controlled by either a remote or by the app on my phone.  Plus, the price was super reasonable. Much more affordable than comparable units with smaller btu ratings.
