There are many different types of heating systems. Central heating is often used to heat residential, industrial, and commercial buildings. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location, such as a furnace room in a home or a mechanical room in a large building. The heating elements should be located in the coldest part of the room to minimize condensation and offset the convective air current formed in the room. It is important to control air leaks from the outside in addition to properly designing the heating system.

Air Conditioning

An air conditioning system, or a standalone air conditioner, provides cooling, ventilation, and humidity control for all or part of a house or building. Central air conditioning systems with a combined outdoor condensor/evaporator unit are often installed in modern residences, offices, and public buildings. The duct system must be carefully maintained to prevent the growth of pathogenic bacteria. The use of separate indoor and outdoor coils in split systems are most often seen in residential applications but are gaining popularity in small commercial buildings. All modern air conditioning systems are equipped with internal air filters. These are generally of a lightweight gauzy material and must be replaced as conditions warrant. In addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condensor coil. Failure to keep the condensor clean will eventually result in harm to the compressor.


Heat can be removed through radiation, convection, and by heat pump systems through a process called the refrigeration cycle. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants. Some systems include a reversing valve that automatically switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating, or vice versa.

Geo-Thermal Heat Pumps

Geo-thermal heat pumps are similar to ordinary heat pumps, but instead of using heat found in outside air, they rely on the stable, even heat of the earth to provide heating, air conditioning, and hot water. A few feet below the earth's surface, the ground remains at a relatively constant temperature. While they may be more costly to install than regular heat pumps, they can produce markedly lower energy bills - 30% to 40% lower.
