Unfortunately, there are no portable air conditioners that can be used without exhaust. A fundamental feature of all air conditioners it that they have some way to expel the hot air from your room. That is the role of the exhaust hose.
For our most in-depth reviews of the top portable air conditioners, check out this article.
Below, we will answer the three major questions about exhaust hoses for portable air conditioners.
Question 1 — Is it possible to use this AC in a windowless room?
Well, all AC units need to have a place to release heat generated during the cooling process. So there really isn’t such a thing as a portable air conditioner without an exhaust. In fact, all portable air conditioners these days come with an exhaust hose to be placed through the window.
The most sensible method of venting the heat would be a window but in case there is no window, other ideas will do. You can simply install a tube to the air vent. This way, the heat is carried outside directly and the room remains cool.
Questions 2 — is there a difference between the AC and the air cooler?
Generally, an AC works with a Freon system and covers a larger radius with cool air than the conventional air cooler. On the other hand, air coolers work in a slightly different way. They use moisture to cool an area and they are less effective than the portable cooling system.
Question 3 — Can one leave the AC on all night?
Generally, a portable AC works like a refrigerator. This implies that as this appliance cools, condensation occurs. The water is usually collected in a tray with the cooling unit.
There is no risk of the water collected overflowing because the AC will simply shut itself off to prevent this from happening. The same thing applies if the air filter is on the verge of overflowing.
The only danger is plugging the cooling unit into a plug with other appliances. This is because most AC’s use a lot of electricity. Your best bet is to use a dedicated plug to prevent a short and your cooling system will be safe. This is all you need to know about the best portable air conditioner no exhaust.
