Cooling with poorly maintained air-conditioners lead to heating the globe. Since air-conditioning equipment operates with electricity generated from fossil fuel and is charged with hydrochlorofluorocarbons (HCFCs) or hydrofluorocarbons (HFCs), using the air-conditioners and leakage of their refrigerants cause the depletion of the ozone layer and contribute to global warming, which are harmful to all living creatures and the ecosystem.
