Natural gas is commonly known for its use in cooking food, heating water, heating buildings, fueling vehicles and running large commercial and industrial equipment. It is also used for cooling purposes during warm weather with considerable cost savings compared to the electric alternatives available.

Natural gas air conditioning is not something new. In the United States, natural gas in the 1930s and 40s met cooling needs. Electric cooling was only introduced to the cooling market in the 1960s, but the use of natural gas air conditioning still grew because of lower capital costs, good efficiency and very low electric rates. By the 1970s, the use of electric air conditioning increased, while natural gas air conditioning declined, and by 1990, a mere 5% of all air conditioning in the United States was fueled by natural gas. However, many are again becoming conscious of the money they are spending on cooling, as well as environmental issues involved with electric air conditioners and natural gas is back in the picture.

The latest natural gas air conditioning technology is much more advanced than the earlier technology, and these days it provides superior energy efficiency than the older systems did. Natural gas air conditioning is also being offered in a variety of sizes to meet almost every customer's needs in homes of all sizes and large commercial or industrial facilities.

The main advantages of the natural gas air conditioning are many. Not only are the overall operational costs lower than the electric counter parts; they are also CFC-free, which makes them environment-friendly. They are also feasible for use where existing electrical systems cannot be upgraded easily, and where electric air conditioning may prove expensive.
