Heating and Cooling
Two of the biggest energy sinks are the heating and cooling systems. The EPA rates heating and cooling systems using the Energy Star logo to symbolize systems that are more efficient and use less energy. Usually these systems are quieter and have longer lives. Equipment eligible to receive the Energy Star symbol include boilers, furnaces, heat pumps, programmable thermostats, and air conditioners.
Selecting the correct size system for your living space and choosing an efficient model are two crucial ways to save energy. Maintain your current model by cleaning filters, checking ducts for leaks, and installing programmable thermostats to adjust the times the house is heated and cooled throughout the day. Installing a whole-house fan that pulls cool air in and releases warm air through the attic is another effective measure.
The U.S. Department of Energy reports approximately 45 percent of the average utility bill goes to heating and cooling a home. Heating and cooling dwellings in the United States is responsible for producing 150 million tons of carbon dioxide.
