New Construction in Southwest Michigan So you have the blue prints to build your dream home. Why not include the most economical, high-end heating and cooling unit available on the market in your plans. Recently constructed homes come with a pride of ownership that previously-owned houses cannot match. By installing a WaterFurnace geothermal system in your Southwest Michigan home, you transfer that feeling to include your heating and cooling system. Including a geothermal system in your newly built home means you can roll 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!
