Air Conditioners

Central Air conditioners offer an efficient and comforting cooling solution to your home.

An Air Handler (The Indoor Section):	The air handler consists of two parts, a blower and an evaporator coil. Depending on whether the air handler is in conjunction with a furnace or exists as an independent unit, the set up will be slightly different. If the air handler is part of a furnace system, the blower will be housed within the furnace case and serve the dual function of circulating the air for both heat and cooling modes. The evaporator coil will then be adjacent or on top of the furnace. If the air handler is an independent unit, the blower and evaporator coil will be housed together in a single case. The blower serves the function of pulling air from the return ductwork and blowing it across the evaporator coil. Within the evaporator coil, compressed refigerant begins to expand and in the process of expansion to a gas, draws heat from the surrounding air. The cooled air then flows out into the supply ductwork where it is distributed throughout the house. The gaseous refrigerant is transferred to the condensing unit through the lineset.
Lineset:	The Lineset consists of two pipes connecting the indoor and outdoor units, one carrying refrigerant in a gaseous form, the other, in a liquid.
A Condensor Unit (The Outdoor Section):	The condensing unit contains a coil, a fan, and a compressor. The gaseous refrigerant first runs through the coil where the fan pulls air across the coils to help dissipate the heat from the refrigerant. The compressor then takes the cooled refrigerant and compresses it back into a liquid before it passes out of the condensor and into the lineset to head back towards the evaporator coil.
An expansion valve:	Before reaching the evaporator coil, an expansion valve regulates the pressure of the refrigerant and whether or not the refrigerant continues on through the system again.
The Ductwork:	The supply and return dectwork serve to pipe the cooled air throughout the home and take the warmer air into the air conditioning unit.
The Thermostat:	The thermostat acts a control, monitoring the temperature of the house, and determining in which mode the system should be functioning.

Benefits of an Air Conditioning System

Compared to window or through the wall units, central air conditioning units are much more efficient.
The system improves the health of the household by filtering the air for dust and allergens.
Greater control of the indoor environment. Central Air Conditionign systems cool the entire house and not just a single room and do so more universally.
The compressor is located outside the homes in typical residential split units, reducing the noise of the system.
Air Conditioners come in several different forms including ducted and ductless units, split or packaged units, and multi-zone or single-zone units, providing the customer with a range of options.

Disadvantages of an Air Conditioning System

The initial cost of installation may be more expensive.
Homes without ductowrk systems will need to have one installed, usually requiring minor or major renovation work as walls or flooring may need to be opened up to run the ductwork.
Air Conditioners require yearly maintenance.
