I was left with a question or two after i had the rep. from florida geo thermal. How much yard do you need for slinky loop (was told i didn't have enough yard ) ? My house is 1720 sq. feet. Their doesn't seem to be anyway to cut the cost of drilling a vertical hole for the 3 loops ? What is the difference in split geothermal units for carrier ,
 train ? Do i really need a furnace ? We also talk about redoing the heat pipes . what is typical price for a split geothermal unit / full fledge geothermal unit ?
