Hi Glennjanie - I live in the Northeast, just bought an old house (no A/C, baseboard heating w/oil furnace), am thinking of upgrading. Thinking of installing geothermal, know the basics (eg, how it works in principal, various different geothermal layouts, etc), but cannot seem to find any information for 'intermediates.' I am interested in projected costs, pluses/minuses, how to find a good installer, individual's experiences, etc,etc...

any thoughts?
