The U.S. Environmental Protection Agency (EPA) promotes residential energy efficiency because household energy use contributes to air pollution, including 20 percent of all U.S. emissions of carbon dioxide. It also accounts for 26 percent and 15 percent of all U.S. emissions of sulfur dioxide and nitrogen oxides, respectively.

Furnaces

Furnaces are the most commonly used residential heating system in the United States.

Approximately 38 million gas furnaces are currently operating in U.S. homes and approximately 2.5 million of these furnaces are replaced annually. A 15-year-old furnace may be only 66% efficient and cost up to $730 per year to operate. A new high-efficiency furnace can be 90% efficient or greater and cost as little as $525 to operate annually. Choosing to purchase a furnace in the 90-96% efficiency range can reduce pollution and save homeowners hundreds of dollars over the equipment's lifetime.

 Products qualifying for this EPA program will be identified by the EPA Energy Star logo.

How do you purchase an Energy Star furnace?

Purchasing energy-efficient products becomes easier for consumers, as now they can simply ask for Energy Star models when working with a contractor to select a new furnace.

Over 10 years, an Energy Star furnace could save $1,700 relative to an old furnace, and $920 relative to a new standard furnace.

Why Energy-Efficient Air Source Heat Pumps and Air Conditioners?

About half of all energy used by households goes to heating and cooling the home. Over 7% of all homes are heated and cooled with air-source heat pumps and 24% of new homes are built with them. Also the number of central air conditioning units in homes is increasing rapidly. Seventy-seven percent of new homes are now built with central air conditioning, up from 43 % in 1972, and over 40% of all existing homes now have central air conditioning. In 1994, over 1 million air-source heat pumps and almost 4 million central air conditioners were shipped from manufacturers &151; the most ever.

By increasing the efficiency of new air-source heat pump and central air conditioning units being installed, we can dramatically reduce the nation's energy consumption and resultant pollution. More efficient equipment has the added benefit of helping consumers save money on their energy bills.

The Energy Star air-source heat pump and central air-conditioner program is a voluntary partnership between manufacturers and EPA to stimulate the market for high-efficiency products.  Energy Star air conditioners are 20 percent more efficient than ones currently meeting the federal government standards. Energy Star air-source heat pumps and central air conditioners could save consumers over $350 million per year by the year 2000 in heating and air conditioning bills.

 Purchasing Energy Star Heat Pumps and Air Conditioners

Utilities all over North America are promoting high-efficiency heat pumps and air conditioners because they help reduce peak demand and provide higher customer satisfaction. Energy Star heat pumps and air conditioners also produce a variety of other benefits:

• Energy bills are dramatically reduced
• All units come with a manufacturer's warranty
• Pollution is reduced through the use of high-efficiency products.

In addition to asking for Energy Star when purchasing heat pumps and air conditioners, consumers should consider the following:

• Make sure the unit is properly sized and installed to ensure maximum comfort and efficiency.
• Contractors should be well trained in the proper installation of air-source heat pumps and central air conditioners.
• The duct work should be installed properly, since an improperly installed system can dramatically reduce efficiency.
