Why energy-efficient air-source heat pumps and central 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. This will also help utilities offset their peak loads and avoid having to construct costly new power plants. More efficient equipment has the added benefit of helping consumers save money on their energy bills.
