How to work a cooling system

When I made the decision to have central air conditioner installed into our home, I started doing some hunting around.  I didn’t want to make a bigger investment without being knowledgeable about the machine.  I thought I had a decent system of how an AC operated, even though I was not correct.  The majority of cooling units are split devices, which consists of an indoor air-handling component and an outdoor condensing device.  The indoor air handler houses a supply fan, a AC coil, and the expansion device.  The outdoor component consists of a compressor and a condenser coil.  The A/C works to cool and dehumidify indoor air by going over a chilly coil surface.  The indoor coil is actually made up of rows of tubes that pass refrigerant through the coil.  As the warm air passes over the indoor cooling coil, it heats the chilly refrigerant and transforms it into a sizzling gas.  The gas is then pumped from the coil to the compressor, and finally,  the outdoor condenser.  The heat is then displaced, creating condensate, as the coolant is condensed back into a liquid, and the concept is simply repeated over and over, creating a cooling effect in the house.  The seasonal energy efficiency rating (SEER) shows how effectively the A/C manages the cooling process.  The larger the SEER rating, the larger energy efficient the equipment, and the smaller the operational costs. Machinery with a higher SEER, but, cost far more to buy.  I made the choice that it was worth a bigger initial investment to trim down operational costs every month.
