New Construction in Rochester So you have the plans to build your dream home. Why not include the most economical, luxurious 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 adding a WaterFurnace geothermal system in your Rochester home, you transfer that feeling to include your heating and cooling system. Combining a geothermal system in your newly built home means you can pass the cost into your monthly mortgage payment. The money you save in operating costs will typically offset the increase in mortgage payment - which means you may see a positive cashflow!
