Geothermal FAQ Retrofit:
Will my existing ductwork function with this system?
Yes, in most cases. Your dealer or installer will be able to determine ductwork requirements and if any minor modifications are needed.
Will an underground loop affect my lawn or landscape?
No. Research has shown that loops have no adverse effects on grass, trees, or shrubs. Most horizontal installations require trenches about six inches wide. Temporary bare areas can be restored with grass seed or sod. Vertical loops require little space and do not damage lawns significantly.
My yard contains many shade trees. Will this affect ground temperature and my ability to use it as an energy source?
Not at all. The system is installed deep enough that it utilizes constant ground temperature.
Yes. Called dual systems, they can easily be added to existing furnaces for those wishing to have a dual-fuel heating system. Dual-fuel systems use the geothermal system as the main heating source, and a fossil fuel furnace as a supplement in extremely cold weather should additional heat be needed.
Geothermal systems will reduce your heating and cooling costs regardless of how well your home is insulated. However, insulating and weatherizing are key factors in reducing your heating and cooling costs, and increasing your comfort from any type of heating and cooling system.
