New Construction in Salem So you have the plans to build your dream home. Why not include the most economical, 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 beat. By installing a geothermal system in your Salem home, you extend that feeling to include your heating and cooling system. Including a geothermal system in your newly constructed home means you can roll the cost into your monthly mortgage payment. The money you save in operating costs will generally offset the increase in mortgage payment - which means you may see a positive cashflow!
