Do HVAC Systems Emit Greenhouse Gases?
The vast majority of people around the world are now familiar with global warming and many of them know what greenhouse gases are. To reduce global warming, scientists recommend use of appliances and machines which do not produce greenhouse gases. Some environmental activists have put some blame on the HVAC industry for the depletion of the ozone layer above the earth’s atmosphere. The question environmentally-conscious consumers are asking today is – do HVAC systems emit greenhouse gases? Read on to find out.
What are Greenhouse Gases?
These are chemicals which can alter the structure, composition and quality of air when released into the environment. For instance, most greenhouse gases are known to deplete the ozone, which is known to block out harmful UV rays. When UV radiation finds its way onto the surface of the planet, environmental temperatures are bound to rise, leading to warming of the planet and melting of polar ice. A good example of a greenhouse gas is CFC (chlorofluorocarbons). These gases were originally used as refrigerants in air conditioning systems. When the AC system develops a leak and the CFC finds its way into the environment, the gas can cause depletion of the ozone.
Due to its harmful nature, phasing out of CFCs began in the year 1995. In its place, HCFC was used. Hydrogenated Chlorofluorocarbons are just as effective as CFCs, but less harmful to the environment. The government is still has concerns about the use of HCFC and plans to have the refrigerant phased out by 2030.
It is important to note that the responsibility of combating global warming does not belong to governments and activists alone. Consumers also play a crucial role. If you have an old air conditioning system which still uses CFC, it is crucial you make the switch to a device using HCFC.
Consumers are advised to buy Energy Star-rated AC machines. Compared to other air conditioning devices on the market, Energy Star rated ACs are over 10 percent more energy efficient. This means you will not only be saving money on cooling, but also protecting the environment. Follow us for more articles that will keep your heating and cooling systems running efficiently.
