Our Geothermal Installation & Replacement Process

Geothermal installation is a multi-phase project that requires specialized expertise. Here’s how Continental Services delivers your system from start to finish.

Installation Timeline

We assess your property’s soil conditions, available land area, and your home’s heating and cooling loads. This determines the optimal loop field configuration—horizontal, vertical, or pond/lake—and the right WaterFurnace unit for your needs.

We design a complete geothermal system including loop field layout, indoor unit placement, and ductwork modifications. All necessary permits are obtained and the project timeline is confirmed.

The ground loop—a series of sealed polyethylene pipes—is installed underground. Vertical loops require drilling, while horizontal loops use trenching. Once placed, the loop is pressure-tested, filled, and sealed.

Your WaterFurnace indoor unit is installed and connected to the ground loop. Ductwork is evaluated and modified as needed for optimal airflow. Electrical connections, thermostat, and desuperheater (for hot water assist) are configured.

The entire system is tested in both heating and cooling modes. Loop flow rates, refrigerant charge, airflow, and all safety controls are verified. We walk you through system operation, maintenance needs, and warranty documentation.

Warranty & Protection

Geothermal systems are built to last, and our warranty coverage reflects that long-term value.
