It is hard to imagine living with out the ability to conveniently adjust the climate of our homes and work places thanks to the technology with heating and cooling units. Modern central heat owes a great deal to the radiator, which was originally invented in the 1850s by a polish-born Russian businessman living in St. Petersburg, Franz San Galli. Although some of the basic concepts behind air conditioning can date back to ancient Egypt, the first modern electrical air conditioning unit was invented in 1902 by Willis Carrier in Buffalo, New York. Today there are an estimated 525,000 central air systems now in the New York City and Westchester County areas of downstate New York alone. The amount of window units in this area is estimated to be in the millions! In 2011, 55 percent of new air-conditioning units were bought in the Asia Pacific region, most likely influenced by the incredibly high humidity and tropical climate in that region.

Although these climate adjusting units make life much more comfortable, in the long run it could be seriously damaging to our environment. Air conditioning units draw use an incredibly high amount of electricity in order to operate. This process delivers a sort of double whammy in terms of effecting the natural climate change, since both the electricity the units use and the coolants they contain have shown to result in planet-warming emissions. The best way to reduce these emissions, is to ensure you are keeping your heating and cooling units off when they do not need to be running, and if they are running, ensuring they are running as efficiently as possible. To ensure these units are running as efficiently as possible, it is a good idea to have them serviced annually by a HVAC (heating ventilation and cooling) contractor. An HVAC contractor will ensure that all your heating and cooling units as well as your ducts are clean, free of any debris, and running as efficiently as possible. For example, if your air has dirty air evaporator coils, it may have lost most of its cooling capacity. This will result in your air conditioner running more often to maintain the cool climate you selected. HVAC services can notice this common problem and clean or replace the evaporator coils.

Other methods such as investing in new heating and cooling units that feature energy efficient technology will help to limit the amount of harmful emissions, as well as limit your electricity bill! An HVAC company can help you chose the best unit for your situation and install them for you for a fee. Heating and cooling services are a useful and important measure to take every year to help save the environment!
