We have central air , however we have a good sized basement with the laundry room and storage , along with our dogs come to the area . We needed a “boost “ as we found the basement staying nice and cool also assisted in the months of Summer heat .  
Not only does this attractive unit get the job done - and it is an energy saver , but I can just set the timer and thermostat to our pleasure .   Runs nice and quiet , too !  Very pleased !!!!
