Most people think that air conditioners simply add cold air to a room. What they don’t know is that your A/C unit is a complex and well-designed machine capable of turning the existing hot or room temperature air into cold air. It literally recycles the air until a desired temperature is reach (whatever you determine using your thermostat).

Think of your unit as a smaller version of your refrigerator without the insulated box.

The evaporation cycle of an air conditioner starts with the compressing of freon gas which causes the compressor inside the unit to get hot. The hot gas runs through coils to get rid of its heat in turn creating a liquid. The freon runs through an expansive valve and then evaporates to become cool, low pressure freon gas. This cool gas runs through a second set of coils to eventually release cool air into the building or surrounding space.

Your air conditioner is a multi-functioning tool that cools and filters the air that passes through it. This is ideal for helping to rid the air inside of your home of dust, pollen mold spores and other nasty allergens.

Some air conditioners also include humidifier functionality. Humidifiers take the excess moisture from the atmosphere. A humidifier in your A/C uses the captured moisture to cool your system before sending it out (usually outside) through a hose.
