Window AC / September 15, 2018 / Babette Arsenault
The back the part that hangs outside should have the vents where water will drip out. Carefully place it on the window sill facing the right way. There should be ridges around the perimeter of the air conditioner to show you where it should line up with the window. Once you have this lined up slide open the side panels. These are designed to fill up the rest of the window that the device does not fill. Slide them as tightly over as you can. Have the top sash of the window lowered carefully and slowly down until it comes into firm contact with the top of the conditioner. The frame should be very tight against it to brace it and keep it from falling.
If there is no central hot air heating then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed then do not force the issue and go another option. Ductless split type air conditioning may be your best option.
A window air conditioner is supposed to stay in place. This is different from a portable unit which rests on casters so that you can roll it from room to room. In most cases however a window unit will provide better cooling at a lower price that what a portable air conditioner can offer. Moreover you can install a window unit in each room if necessary. By many estimates having two or three window units is still cheaper than investing in a central system. When you are choosing a window air conditioner it is a smart idea to take measurements of the room you plan to cool.
