New Construction in New Jersey So you have the blue prints to construct your dream home. Why not include the most dynamic, high-end heating and cooling unit available on the market in your plans. Newly constructed homes come with a satisfaction in ownership that previously-owned houses cannot beat. By installing a WaterFurnace geothermal system in your New Jersey home, you transfer that feeling to include your heating and cooling system. Including a geothermal system in your recently built home means you can roll the cost into your monthly mortgage payment. The money you save in operating costs will generally balance out the increase in mortgage payment - which means you may see an increase in cashflow!
