mgguy said "geo-thermal is almost five times the cost of a gas furnace, and will not last long enough to even hit the break even point. want to save money on energy costs......insulation and lots of it "
no, it is not 5x the price. and yes, you can see your money back over time. i gave geothermal and heat 4000sf of space with an electric furnace and infloor heat in 3000sf and pay less than $200/month on equal payments.
