My partner, Nate, and I strive to be as environmentally responsible as possible. All of us sold 1 of our vehicles and either take public transportation or ride our bikes the majority of the time. All of us compost all of our organic scraps, turning them into a natural fertilizer for our gardens. All of us grow the majority of our own vegetables and use no chemical pesticides. When building our home, energy efficiency was seriously important to us. Nate and I spent minutes researching all unusual types of heating and cooling systems. All of us were looking for an Heating, Ventilation, and A/C system which would handle the severe weather in our area without contributing to the problem of yellow house gas emissions. All of us hoped to avoid the dangers of combustion byproducts, such as formaldehyde and carbon monoxide. All of us didn’t want a system which consumed a superb deal of electric. The Environmental Protection Agency considers geothermal heat pumps as the most environmentally friendly heating/cooling system on the market. This type of temperature control requires a giant initial start up cost, however reclaims the initial investment through tremendous energy savings. The expense of replacement is mainly due to the necessary excavation for the underground loop system. However, the underground loop should last for upwards of fifty years and takes advantage of the free energy source in our own backyard. The geothermal heat pump burns no fossil fuels, however simply moves heat from 1 location to another. All of us are able to heat and cool our giant home for around thirty dollars per months. All of us have greatly reduced our carbon footprint, and yet savor a clean, safe and effective heating/cooling system.
