How Can I Increase The Cooling Capacity Of My Portable Air Conditioner?

How Can I Increase The Cooling Capacity Of My Portable Air Conditioner?

While you can put up a portable air conditioner and forget about it, there are some things you can do to increase its cooling capacity.

1) As Much As Possible, Keep The Exhaust Hose Straight

The exhaust hose’s job is to transport warm air out of the room through a window, door, or drop ceiling. It should be aligned and free of kinks and bends for best performance.

Warm air will not be evacuated adequately if the hose is twisted, and the unit will have to work harder to deliver more significant cooling. Moisture in the evacuated air will also collect in the hose, causing damage to the machine and reducing its service life.

2) Shut All Windows and Doors

It is an essential feature because moving the AC unit from room to room would be difficult if it required a different receptacle. A surge protector, which can offer a layer of protection against short power outages, maybe a good option. It’s also good to track how many appliances are plugged into the outlet so that the circuit isn’t overloaded.

Is it OK to run a portable air conditioner continuously?
