The Facts About HVAC Systems And Greenhouse Gases

The majority of HVAC systems emit greenhouse gases

Do HVAC systems emit greenhouse gases? Many consumers have asked themselves this question. If you’re concerned whether or not your HVAC system is contributing to the depletion of the ozone layer, then you first have to determine what type of HVAC system your home uses. But more than likely the answer is –yes. Most heating and cooling systems burn some type of fossil fuel for energy. Fossil fuels can be either oil, natural gas, or propane. If your heating system uses any of these for energy and heat, then it does emit greenhouse gases into the atmosphere. Even though some heating systems use electricity for heating, they still contribute to greenhouse gas emissions indirectly. The electricity needed to run the heat pumps will most likely come from a power plant that burns some type of fossil fuel to create the electricity.


How do air conditioners emit greenhouse gases?

It may seem like an air conditioner would not emit any greenhouse gases since it does not burn any fossil fuels to produce heat. Beside the fact that it uses electricity from a power plant, air conditioners use refrigerants which are a source of greenhouse gases. Refrigerants consist of chlorofluorocarbons which have been shown to contribute to the depletion of the ozone layer.


Reducing greenhouse emissions

The only type of HVAC system that will not emit any greenhouse gases either directly or indirectly is one that uses no refrigerant and is completely powered by an energy source that emits absolutely no greenhouse gases, such as wind or solar power. While it is feasible to produce HVAC systems that produce very little or no greenhouse gases, they would be extremely costly and time-consuming to create and install. The best way to contribute to the reduction of greenhouse gas emissions is to use heating and cooling systems in the most efficient ways possible.

By using appliances and HVAC systems that are environmentally friendly and carry the Energy Star seal of approval, consumers can greatly contribute to the reduction of greenhouse gases. Performing regular maintenance on heating and cooling systems as well as practicing energy saving behavior can also help in reducing the emission of harmful gases into the atmosphere.
