New Construction in Lime Springs 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. Newly constructed homes come with a satisfaction in ownership that previously-owned houses cannot beat. By installing a WaterFurnace geothermal system in your Lime Springs home, you transfer that feeling to include your heating and cooling system. Including a geothermal system in your recently constructed home means you can roll the cost into your monthly mortgage payment. The money you save in operating costs will generally offset the increase in mortgage payment - which means you may see a positive cashflow!
