New Construction in Knoxville If you're planning to build the home of your dreams, why not install the most efficient and high-end heating and cooling system on the market today? A newly built house comes with a certain peace of mind that's not common among formerly owned homes. Installing a WaterFurnace geothermal system can extend that peace of mind to your heating and cooling system as well. Including a geothermal system in your newly built home means you can pass the cost into your monthly mortgage payment. Your savings in operating costs will generally offset the increase in mortgage payment - which means you may see an increase in cashflow!
