New Construction in Central So you have the plans to construct your dream home. Why not include the most efficient, luxurious heating and cooling unit available on the market in your plans. Recently built homes come with a pride of ownership that previously-owned houses cannot match. By adding a geothermal system in your Central home, you extend that feeling to include your heating and cooling system. Adding 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 typically offset the increase in mortgage payment - which means you may see an increase in cashflow!
