Nowadays, the air conditioning supply has become very popular and it is more the norm than the exception. Air conditioning systems not only cool but they also filter and the air we breathe and make it cleaner and much more comfortable.

The use of air conditioning systems depends on both weather and climate. Most people who live in energy efficient houses have an air conditioner. If you want an air conditioner and you do not know which is the best for you, we are going to give you some tips to consider before purchasing the right one for you.

One of the most important factors is the star rating. Studies have shown that size is very important as most air conditioners do not work properly because they are over-sized. Over- sized air conditioners turn off and on more often than they should and use much more energy.

There are several types of energy rating labels for air-conditioning systems. There are some types which are used only for cooling and they have a blue box and a blue band of stars for the energy consumption figure. There are also some models which have a reverse- cycle. These ones can be used for cooling and heating as well. These ones have two bands of stars: the red band shows the efficiency when heating and the blue band shows the efficiency when cooling.

There are also air-conditioning systems which can be used only for heating and do not have any cooling features. These ones have a red band of stars.

Before purchasing an air conditioning system decide which is the AC you need: a portable one, a fixed one or a split air one.

Before deciding which one is the best for you and your house, you should also consider air conditioner installation cost. There are some systems which are really expensive but are not so efficient, and some which are very efficient but really cheap. People are usually interested in cheap products, but we recommend you to make your own research and compare several air conditioning systems before purchasing one. Make sure that the company which provides the air conditioning system you are interested in is an authorized one, if it installs it for you and if it offers you a warranty. Start your research on the Internet. There are many websites which allow you to compare products and services and help you make the right choice.
