There are occasions when it is physically impossible or impractical to install a
central air conditioning system or heat pump. Through-the-wall and window units
are noisy, drafty, and allow unneeded air infiltration when not in use that can
waste energy and allow insects or other pests to invade the home or office.

Split systems offer higher efficiency and reduced noise without a large hole in
the wall or an open window. By separating the compressor and condenser coil from
the fan and evaporator coil, the noisiest component is away from the room. The
indoor unit will usually have remote control capabilities and a timer to cycle
the system only when needed. The indoor unit is called an air handler because it
has the evaporator coil, blower, and controls inside. The outdoor unit is called
the condenser. They are connected together with refrigerant piping and control
wiring, similar to a central system.
Some manufacturers use low voltage to control the system, others use line
voltage. Caution must be taken when opening up the cabinet to shut power off
when servicing. The most important service item is dirt. Screens or filters can
usually be found behind the front grill of the air handler. Tabs allow them to
slide out for cleaning. Keep vegetation and debris away from the outdoor unit to
allow good air flow for maximum cooling efficiency. An occasional blast from a
garden hose with the system shut down will help keep the condenser clean.
Relatively new to the American market, ductless split systems have been in use
in Japan and other markets for a long time. Until recently none were of U.S.
manufacture, but increased demand changed that.
