New Construction in Columbus So you have the plans to build your dream home. Why not include the most dynamic, luxurious heating and cooling unit available on the market in your plans. Recently constructed homes come with a satisfaction in ownership that previously-owned houses cannot match. By adding a WaterFurnace geothermal system in your Columbus home, you transfer that feeling to include your heating and cooling system. Combining a geothermal system in your newly constructed home means you can pass the cost into your monthly mortgage payment. The money you save in operating costs will most likely offset the increase in mortgage payment - which means you may see an increase in cashflow!
