Makeshift Air Conditioning Vents
A small air conditioning unit like the one mounted on that wall can only cool down a single room. And calling someone to install a central air conditioning system costs a lot of money. So, this person grabbed a long plastic bag and taped it to the small air conditioning unit. This created a tube of cool air that traveled all the way to another room. Admittedly, it’s not a permanent solution, but it will do until they can afford another air conditioning unit.
