Definition of a System

In the previous checklist, we kept referring to a system.  We don't want to assume that everyone knows what constitutes a system, so here is our defination.

FORCED AIR SYSTEM - The most common type of system is a forced air system which utilizes air ducts to carry conditioned air throughout your home.  A typical forced air system utilizes an air conditioner, furnace, and an evaporator coil.  Most commonly, this is called a Split System because it requires equipment outside as well as inside.  You may also hear it called Matched System.  This Matched System refers mainly to the air conditioning aspect of your system.  Read on to find out how it works.

CONDENSING UNIT - The most recognizable portion of the cooling system is the condensing unit, commonly referred to as the outdor unit.  Within the condensing unit lies the heart of the system, the compressor.  The compressor is responsible for pumping the refrigerent in order to meet the cooling requirements of the system.  The other part of the condensing unit is the condensing coil.  The coil's main function is to dissipate heat from the refrigerent, changing or condensing the refrigerent from a vapor to a liquid.

FURNACE - This is another important component of your air conditioning system as it houses the evaporator or indoor coil. It's function is vital. As indoor air flows across it, heat and humidity are drawn out leaving the air that returns to your living space cool, comfortable and conditioned. This brings up the topic of Matched System again. The evaporator coil is designed to work in tandem with your outdoor unit and your furnace. It is imperitive that they match in both size and efficiency as these units are designed and engineered to work together in balanced efficiency.

So, if you are getting ready to replace your system, you should consider replacing all integral parts of your system as an unbalanced system means higher than necessary cooling bills and lower levels of comfort.

BALANCED EFFICIENCY = THE HIGHEST LEVEL OF COMFORT AND LONG EQUIPMENT LIFE.
