Window air conditioners are one of the most commonly used and cheapest type of air conditioners. To install one of these units, you need the space to make a slot in the wall, and there should also be some open space behind the wall.
Window air conditioners are comprised of components like the compressor, condenser, expansion valve or expansion coil, and the evaporator or the cooling coil, all housed in a single box. There is also a motor which has shafts on both sides. On one side of the shaft the blower is connected, which sucks hot air from the room and blows it over the cooling coil, thus cooling it and sending it to the room. On the other shaft the fan is connected, which blows the air over Freon gas passing through the condenser.
The window air conditioner is the cheapest of all air conditioning systems. If your room or office size is about less than 100 sq. ft. a window air conditioner of about 0.8 ton can be good enough. If the size of room is more than this but less than 200 sq. ft. your HVAC designer will recommend a window air conditioner of about 1 ton. For rooms of bigger sizes but less than 300 sq. ft. the system of about 1.5 ton is advisable. However, these sizes may change depending upon the number of people occupying the space, its alignment with respect to sun, and other sources of heat generation inside the room. Consult us for your HVAC to find out the exact size of window air conditioner suitable for your space.
