New Construction in Columbus If you're ready to build the home of your dreams, why not install the most economical and luxurious heating and cooling system available today? A newly constructed house comes with a certain peace of mind that's not common among formerly owned homes. Owning a WaterFurnace geothermal system can transfer that peace of mind to your heating and cooling system as well. Including a geothermal system in your newly constructed home means you can pass the cost into your monthly mortgage payment. Your savings in operating costs will most likely balance out the increase in mortgage payment - which means you may see an increase in cashflow!
