Geothermal Heating & Cooling

Efficient comfort from the ground up.

Experience the most energy-efficient home heating and cooling system available with a geothermal heat pump installed by DRG Mechanical. Serving Northwest Iowa, Southeast South Dakota, and Southwest Minnesota, we design and install geothermal systems that offer year-round comfort and long-term savings.

How Geothermal Works

Underground loops circulate fluid to transfer heat between your home and the ground. In the winter, the system draws heat from the earth and delivers it indoors. In the summer, it pulls heat out of your home and disperses it underground. This natural, closed-loop process makes geothermal one of the most efficient HVAC systems available today.

Why Homeowners Are Switching to Geothermal

Geothermal systems use the earth’s stable underground temperature to efficiently heat and cool your home. Instead of creating heat, they move it — delivering consistent comfort in every season.

Lower Energy Bills: Save up to 70% on
All-Season Efficiency: No matter the weather, geothermal keeps your home comfortable.
Quiet Operation: No noisy outdoor units — just smooth, silent performance.
Eco-Friendly: Reduce your carbon footprint with clean, renewable energy.
Durability & Value: Indoor components last 20–25 years, and ground loops can last 50+ years.
