Window AC / September 1, 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.
The Advantages of window air conditioning units: They are cheap. Compact. Sometimes provide partial ventilation. No installation required. Easy transportation from place to place. Suitable for apartments summer cottages and offices. Window air conditioner can be easily installed in a shop on wheels. Another important advantage is long lifetime: window air conditioners seldom get to a service center mostly after many years of usage (the simpler the system - the more reliable it is). The disadvantages: High noise level. They block a part of the window stealing the daylight. The window frame must be altered.
To help make that decision more clear I will explore some of the positives and negatives of the two major options. Ductless split type units are also becoming more of an option. I will do another article on that option. To include that in this article would just be more confusing. So for now we will just look at window air conditioners and central air conditioning. Central air conditioning is the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed.
