The HVAC system has many types and applications, they are classified as central or local. Local HVAC systems provides heating and cooling to a specific area or room, they do not function for the whole structure. This kind of system includes wood or pellet stoves, space heaters and window air conditioners. If an Electric baseboard is installed in a single area, it is considered as a Local HVAC system.


The Central HVAC system provides the much needed heating, cooling and ventilation in the entire building such as from a boiler or furnace. In order to achieve heating and cooling in this kind of system, it circulates heated water or steam through the pipes or ductwork.


A compressor and a condenser unit that uses a refrigerant or coolant such as Freon is often used in Central air conditioning. The refrigerant absorbs the heat, turns to vapor, travels to the compressor and moves to the outdoor coil where the heat is forced out, it is circulated through the copper tubing. Before returning to the indoor coil, the refrigerant passes through a device where it is converted to a low pressure and low temperature liquid. The structure will be provided with a cooling effect when the cool air is already circulated through the ductwork.


To be able to get the maximum benefit of your unit, an HVAC professional will help you determine the kind of HVAC system that is right for you and your needs.  You should  look for a qualified and certified HVAC contractor   to help you with the proper installment of your unit in order to meet your cooling and heating preferences.
