If your electric supply is green and you heat and cool your home with a heat pump, your energy use becomes carbon neutral, your indoor air quality is improved, and your energy use is dramatically more efficient. Heat pumps are clean, quiet, efficient, and green!
A new geothermal or air source system is a big investment, but it is often a choice that does not come around but once every 20 years. Please consider going electric next time you have the chance to get efficient, fossil fuel free heating and cooling!
