Window AC / August 26, 2018 / Denise Brisette
The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning but the major part of it should be adequate. To use the existing furnace and ductwork a coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will be needed to hook the thermostat the furnace and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
A wall with simple sheet type siding may be only 6 inches thick whereas a brick or stone wall can be much thicker. So wall air conditioner sleeves have ventilation louvers only in the back to avoid louvers being covered by the wall edges. This limits the amount of ventilation space available in turn limiting how powerful the unit can be. Wall air conditioners generally dont get much over 14000 BTU depending on the brand. So are they interchangeable? This question usually arises when someone needs a lot of cooling power in a room without suitable windows for a window unit.
They are also easy to install unlike split air systems and central ac. Installing a window unit is an easy DIY job that can be tackled in an hour or so. Also because they are installed in a semi-permanent fashion you just set it and forget it. Unlike portable ac units which are often wheeled around from room to room a window unit is designed to stay put. In spite of all of these benefits however window units have one major drawback: the noise. These units are loud and different models can range from being moderately annoying to downright deafening.
