If you have a small area to cool in the summer - say, one or two rooms a room air conditioner may be a more economical choice than a central air conditioning unit. It will cost less initially and it will cost less to operate in the long run.
Most room air conditioners sit in a window where they can exhaust warm air to the outside. Window installations can be drafty, however, so at the end of the warm weather season some people remove the unit from the window and store it for the winter. Room air conditioners can also be built into the wall for a more permanent installation.
Keep in mind that, when choosing a room air conditioner, size is important. A unit that is too small will run continually without cooling the room effectively. On the other hand, if you buy a unit that's too large for the space you're cooling, it actually will be less effective than one that's the correct size. Bigger isn't necessarily better.
Air conditioners work by removing both heat and humidity. Humidity condenses from the air when it passes over the air conditioner's cooling coils. So a unit that is too big will cool the room so quickly that it won't have the opportunity to remove as much humidity from the air as it should. As a result, the unit will keep turning off and on and the room will feel damp, clammy and less comfortable. A properly sized unit, on the other hand, will remove humidity effectively as it cools.
Also remember that larger units cost more and use additional energy. Running a smaller unit for a longer period of time will use less energy to completely cool a room than running a larger unit for a shorter time.
Thru-wall Air Conditioners Packaged Terminal Heating and Cooling units (PTAC)
Thru-wall air conditioners were developed in the late 1950's. Over the next forty years many companies engineered, manufactured and installed a variety of different units throughout the United States and Canada. Today, a number of these companies are no longer in business or have discontinued their line of thru-wall air conditioners and no longer carry replacement parts. Metro AC offers replacement air conditioners and heat pumps that are interchangeable with units no longer available from the original manufacturer. These units are engineered to fit perfectly within the existing wall sleeve, thereby reducing installation time and expense.
