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