New Construction in Lime Springs So you have the plans to construct your dream home. Why not include the most efficient, high-end 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 beat. By installing a WaterFurnace geothermal system in your Lime Springs home, you extend that feeling to include your heating and cooling system. Combining a geothermal system in your recently constructed home means you can pass 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 a positive cashflow!
