Invest in a geothermal heating and cooling system – This is the most environmentally responsible and energy efficient system available on the market. The direct exchange ground source heat pump uses the earth’s constant underground temperatures to heat the home in the winter and cool it in the summer. These pumps can reduce heating and cooling costs by as much as 50 percent, and they usually last three times longer than air source systems. Although these systems can be a bit pricier than traditional heating and cooling systems, electric utility companies have been willing to cover some of the costs of installation or offer rate guaranties. The discounts can amount to hundreds of dollars, so be sure to ask.
