Any reason to not use one of these to help cool down a single room?
Basically the title. We have a two story house and our upstairs master bedroom is always at least 5/6 degrees warmer than the main level in the summer, especially during these heat waves. It’s not really an issue during the day but we have to keep the main level at 70 for the bedroom to get below 76. It gets hard to sleep sometimes even with fans, and I hate wasting all the energy/money to keep the main level at 70 just to have a shot at not sweating through our sheets lol We’ve tried closing a few vents on the main level at night and it helps maybe a degree or two. This seems like a relatively cheap fix to at least get some more a/c into the room, we would probably only be using it at night as we’re not really up there much during the day. Anyone have luck/no luck with these? I don’t usually trust amazon reviews.
