According to most environmentalists, the ozone layer is getting depleted by greenhouse gases, some of which are emitted by HVAC equipment. This applies for all types of systems, including central, portable and wall-mounted AC units. The ozone layer is what protects the earth from harmful ultraviolet radiation. The gradual depletion of this stratum increases the rate of UV penetration, which permanently raises the earth’s temperature in a process known as global warming.

How A/C Systems Work

Air conditioners are comprised of internal electric coils and an electric pump to transfer air between the outdoors and indoors. The cooling mechanism, known as the evaporator, is what transmits cool air into the house while the hot coil (condenser) releases warm air outdoors. A compressor pump is included to move the refrigerant between these two components, alternately changing it between liquid and gaseous states in order to move the cool and warm air.

Do HVAC Systems Emit Greenhouse Gases?

In the past, air conditioners used chlorofluorocarbons (CFCs) as the liquid refrigerant. As the harmful effects of CFCs began to emerge, manufacturers shifted to halogenated chlorofluorocarbons (HCFCs). These are significantly less harmful than conventional refrigerants.

To combat the harm caused by greenhouse gases on the ozone layer, steps have been taken by authorities. These ensure that HVAC equipment manufacturers only produce devices that are friendlier to the environment and more energy efficient. The production of HCFCs is scheduled to be phased out by 2030.

Increasing the Efficiency of HVAC Systems

The Energy Star program is a joint effort between the Department of Energy and the EPA which sets energy efficiency standards. AC equipment that is Energy Star-rated uses about 10% less energy than traditional units. Some devices even have timers to regulate energy consumption during their operation.

Consumers are encouraged to purchase eco-friendly devices that bear the Energy Star seal. Air conditioner efficiency can be further be boosted by improving insulation around the house, sealing any existing leaks on ducts and ensuring that the unit’s adjustable louvers tightly fit into the window frame.
