You may immediately think of buying a dud for a car, but situations go further than that. For example, you may want to keep your eye out for heating and air contractors installing worthless systems in your home. That is why it is important to make sure you are working with a contractor that offers a lemon guarantee with their installation. Let me explain…

A lemon guarantee with a HVAC company is a contract that agrees you won’t be stuck with a dead product after the technician installs your unit. It means that if your unit should falter, you will be replaced with a new one free of charge.

This is an important quality to look for in your heating and air conditioning contractor. Something you should do as the consumer is to get your guarantee in writing. One should get at least a five year coverage that will take care of the major components of your unit should anything go wrong. The last thing you want is to be assured you have a lemon guarantee and then when something does go wrong you are stuck with nothing to prove it.

It is always important to cover you basis, even with your heating and air contractor. If you want to make sure you are getting the most out of your money and system, do not forget to take advantage of a company that offers a lemon guarantee. You won’t regret it when it’s mid summer and your system turns into a dud.

When an air conditioner breaks down most of the people tend to call the technician to get the unit repaired. There are many simple things which might cause an air-conditioning unit to shut itself down and these simple things can be easily fixed by you saving a whole lot of money. In this article I would like to explain such common issues that can be identified and repaired by you. Before we dive into air-conditioning repair I would like to remind you that at anytime if you feel something is seriously wrong with the unit you need to call a qualified technician.

The first simple thing which most of the people fail to check when the unit is shut down is the electric connection. The unit wire might not be properly plugged or the electric socket could have been burnt, in such cases try connecting the plug to other socket and see if the unit runs. There are times when the plug itself can be damaged, all you need to do is remove the screws of the plug and investigate the wiring of the plug, if you see a burnt section or loose connection of the wire you need to repair that part and your unit will start working.

The next thing which is the most common cause for the unit to shut down is clogging of the filter. It is the most neglected thing by many. If your air conditioning unit is not working first try to investigate the filter. You can asses if the filter is good or not by doing a simple test. Try to observe the filter through battery light. If the light passes easily then the filter unit is ok and if the light does not pass then it mean that the filter has been clogged. Once the filter is clogged the condensers of the unit fail to take up the air inside resulting in shut down of the unit. In such cases you need to simply replace the filter and let the unit shut down for a period of 2-3 hours this will allow the ice to get thawed and the fins should be able to work again once you plug in the unit. Once you have replaced the filter you can also clean the condenser fins as they usually might be clogged. The condenser fins should be cleaned regularly in order to optimize the effectively of the unit.

The next cause could be due to Freon loss, now this might prove a challenge for beginners so it is advisable to call a technician and closely observe how he checks the Freon pressure. If there is a need to replace the Freon, then you need to call a technician who has a license from the EPA.

Who Invented the Air Conditioning Unit?

The need to cool the air in summer has existed for thousands of years, and many methods have been devised to achieve it. However the first modern air conditioners as we know them emerged in the early 1900′s.

The concept of controlling the temperature of a room through programmed machines might be new but cooling buildings is a practice which has its roots in the ancient times. Different societies had adopted different techniques for cooling buildings.

The Romans used to do it by circulating aqueduct water though the walls of their houses while the Chinese inventor Ding Huan of the Han Dynasty invented the Rotary Fan for the purpose of cooling. Similarly, buildings in medieval Persia had cisterns and wind towers for cooling purposes while ventilators were invented in Medieval Egypt for the purpose of causing air ventilation and cooling the environment.

However, the very first modern electrical air-conditioning unit was created by the New York based Willis Haviland Carrier way back in 1902. After graduating from Cornell University, Carrier was given a job at a forging company in Buffalo and was put in charge of designing a machine that would improve the process control of manufacturing in a printing plant.

The creation by Carrier wasn’t restricted to just temperature control but it also controlled humidity. Carrier used the concept of heating through the use of steam and also turned that process inside out to create a cooling effect. To do this he pioneered the idea of sending air through refrigerated coils to cool it and control the moisture content of the air.

This allowed him not only to cool a room, but also control the humidity level. For printing purposes this was a great breakthrough because paper absorbs a great deal of water, and affects the ink alignment significantly, so controlling the temperature and humidity of a room mean far more efficient printing.

However the realization of the enormous implications of this new technology were soon discovered, and it was not long before air conditioners were being designed for homes, offices, cars and factories all over the world. Now many of us cannot live without our air-conditioners! Find out more about portable car air-conditioners at this website http://www.portable-airconditioning-units.com.
