It’s not an air conditioner but the heater works good.I needed an air conditioner for my garage gym. However, since there are no windows sans the door itself, I needed something that could stand on its own, and this was the perfect solution.Now granted, it doesn't work as well as an actual portable air conditioner, and you WILL need to fill it every 8 hrs with water and ice. However... for the 3 hrs I need it in the garage, facing a 8ft x 8ft space with no ventilation, it is perfect.This item doesn't cool the room with 2 icepacks for more than 1 hour! It is just like using a fan! It makes the water slimy after only 1 use! Not worth the $$$!I have had this device for less than 24 hours, and it is useless. This product was purchased for office use in Flordia, in a room with no windows. There is central A/C, so it should not take much to cool this room. When I can get the "water tank" to close (which is a rarity) it barely cools the air. You might as well purchase a fan. No matter how cold the water is, or how many icepacks you use they melt and become useless within an hour or so... IF you are able to get the "water tank" in.Heat pump works amazing, way better than most of the products on the market, heats up my livingroom with ease. HOWEVER!!!!! On product's Amazon page nowhere can you find anything about how this thing cools your room down, nor does it mention the icepacks (yes!!! your cooling source!!!) that come with the machine. I was wondering how this thing could product cool air without an exhaust tube to expell the hot air. If it wasnt for the heat pump, i would have returned this thing for false advertisement.
