Air conditioning units are available in almost all styles and sizes. An indoor system functions by transferring air through the indoor evaporator coil, and heat is taken in to the refrigerant in this particular coil. The refrigerant is then moved to the outside, where the high temperature is depleted with a fan blowing across the exterior condenser coil. An air conditioning system does not create cooler air flow, it eliminates heat from the air. For more information please click here air conditioning units boca raton
