Compressor. Squeezes the freon. Usually located outdoors.
Condensor. Assembly of tubes and fins which allows hot freon
to cool. Always located outdoors. Sometimes called a
"condensing coil". Might look a lot like a radiator on a
car. Same function.
Condensor fan. Blows air through the condensor.
Condensing unit. The box which contains a compressor,
condensor and condensor fan.
Filter drier. Bulge in the copper freon pipe, contains a
material which removes water, and solid particles.
Lineset. Two copper tubes which carry freon in a closed loop
Metering device. Can be one of several different types of
device. Allows the correct ammount of freon to enter the
evaporator. These can be called an orifice, flow rator, TXV,
Expansion Valve, or captube. Depends on the different design
Evaporator. An assmbly of tubes and fins, wh ich allows cold
freon to absorb heat. Does the same job as a radiator on
your car, but in reverse. Gets cold and absorbs heat.
Air handler. Box with fan and ducts, which moves air through
the evaporator. You can use a furnace for an air handler, or
you can have a separate one.
Extrabulator. The device which your HVAC guy won't tell you
how to fix. Sometimes you have to top off the red lantern
oil, or thaw it out with a bucket of steam. It mounts to the
ceiling of the cellar with skyhooks. Real professionals all
know what an extrabulator is. They frequently break, and
have to be replaced. They should be inspected for wear once
Hope this is helpful. You now have considerably more
information. If you read and absorb, you will have
knowledge. If you can use the knowledge, you have wisdom. If
you act with wisdom, you will have fewer problems in life.
