Back in 1983, WaterFurnace was just beginning to install geothermal systems across the United States. More than 40 years later, many of those systems are still providing reliable comfort.
In celebration of Earth Day and the legacy of geothermal technology, WaterFurnace is searching for some of the oldest geothermal units still in operation today. If you have an older geothermal system in your home, this is your chance to share your story and potentially win a brand-new WaterFurnace geothermal unit professionally installed in your home.
As a special bonus for Warren Systems customers and followers, if a local winner is selected and is located within our service area, Warren Systems will provide a FREE 10-Year Geothermal Service Plan to help keep your new system operating at its best for years to come.

The grand prize winner will be announced by WaterFurnace through its official Facebook page.
