New Construction in West Chester So you have the blue prints to construct your dream home. Why not include the most dynamic, high-end heating and cooling unit available on the market in your plans. Newly built homes come with a pride of ownership that previously-owned houses cannot rival. By adding a WaterFurnace geothermal system in your West Chester home, you extend that feeling to include your heating and cooling system. Adding 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 an increase in cashflow!
