I am building a new construction house (2900 sq. ft ranch with full basement) in the Cleveland Ohio area and don't have a natural gas feed. I am looking to install a Geothermal system for the heating . I know that there are several gas wells within 1200ft of the development. would it be reasonable to tap into one of the gas lines or for the cost factor, just install the geothermal system. Conventional Gas HVAC system would cost approx. $9,000 and a Geothermal system would cost approx $25,000
You should investigate any tax rebates associated with a geothermal install in your area. Down south there are steep tax rebates available. Up to 40%. That should make it a no brainer. I am a big fan of geothermal. (when Im not paying for the install) I assume you are installing AC as well.
