New Construction in Mountain Home So you have the blue prints to construct your dream home. Why not include the most efficient, high-end 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 match. By installing a WaterFurnace geothermal system in your Mountain Home home, you extend that feeling to include your heating and cooling system. Including 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 typically balance out the increase in mortgage payment - which means you may see a positive cashflow!
