Central Air Conditioning

Central air conditioning is the most efficient type of air conditioning on the market today. If designed right, these systems will maintain a constant temperature and humidity throughout the conditioned space. If your budget and space permits, always choose central air over any other type. Personal comfort, home temperature and indoor air quality are all extremely important to you and your family, and you will be well rewarded with the money you invested in Central air conditioning for your home.

There are basically two types of central air systems, split systems and package units:

Split System: There are three major parts of a split system that need to be properly balanced and matched to provide peak efficiency and economy.

1. Outdoor Unit: The outdoor unit contains a compressor and a condensing coil filled with refrigerant. A fan blows outside air over the coil, transferring thermal energy between the refrigerant and the outside air. The refrigerant is then circulated through pipes, or line set, to the indoor unit.

2. Indoor Unit: The indoor unit is made up of a coil and blower which is located inside of an air handler or furnace. The blower circulates air through the coil before it is sent to the ducts throughout your home.

3. Line Set: The line set contains the refrigerant which simply circulates the liquid between the indoor and the outdoor unit.

Package Heating & Cooling Systems: In a package system, all equipment is built into an outdoor unit, usually on a concrete slab. The “package” that gives its name provides central air during the summer and heat in the colder months.

Types of package units available:

• Electricity for resistance heating and cooling

• Gas for heating and electricity for cooling

• Heat pump models use electricity

With both types of systems(split or package) ductwork is required to transfer the heated or cooled air throughout the home.
