New Construction in Lexington If you're about to build the home of your dreams, why not install the most economical and luxurious heating and cooling system available today? A recently built home comes with a certain peace of mind that's unmatched among previously owned homes. Installing 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 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!
