When the upstairs turns into a sauna, the portable AC we chose is the DREO 515S โ its smart app cools the bedroom before we even head up. Here's what we bought, plus a few others we seriously considered.
What We Chose

This is the AC we actually use. The smart app cools the bedroom before we even head upstairs, it's quiet enough to sleep through, and it's easy to roll to wherever the heat is worst.
Whether you are trying to cool a bedroom at night, keep a nursery comfortable, or survive a heat wave without blasting the whole house, a good air conditioner should be quiet, efficient, easy to use, and appropriately sized for the space. Below the one we chose, we've rounded up a few others we considered for different rooms and budgets.

By late July our upstairs bedrooms turn into an oven. Heat climbs the stairs all afternoon, and by the time we are wrangling six kids toward bed, the little ones are sweaty and cranky and nobody wants to lie down. For a few summers we just suffered through it with box fans that mostly pushed warm air around.
The one we settled on is the DREO 515S portable AC, and the smart app is what won us over. Mom can cool the bedroom from downstairs so it is already comfortable before we even head up for the bedtime shuffle. It runs quiet enough to sleep through, and the wheels mean we can roll it to whichever room is baking worst on a given day instead of buying a unit for every floor.
Compared with the other portable units we weighed, the DREO 515S struck the honest balance we needed for a big household. Window ACs were a hassle to haul between rooms, and a cheaper portable we considered was loud enough to wake the baby. This one cools fast, the app scheduling means it is not running all day for nothing, and one machine quietly handles the hottest room in a house full of people. For the price, it has earned its spot.
