Advanced Custom Geothermal

We are a full-service heating, cooling, and geothermal contractor located in Kiel, Wisconsin. With decades of experience, we provide residential and commercial HVAC solutions for customers building a new home, updating an existing heating and cooling system, or seeking repair service. Our services include heating solutions, air conditioning and cooling, commercial HVAC work, and geothermal heating and cooling systems.

We specialize in geothermal installations and feature WaterFurnace systems. We have partnered with WaterFurnace and chose its technology for our own heating and cooling system. Our team helps homeowners and businesses explore geothermal based on their property and energy needs. We also offer a free energy analysis for a home or business to estimate the potential savings associated with a geothermal heating and cooling system.

We serve Wisconsin customers and help residents determine whether a geothermal system may qualify for available state or federal incentives. Our geothermal resources include a cost calculator and information about federal tax credits and Wisconsin cash-back incentives. By providing heating, cooling, commercial HVAC, repair, and geothermal installation services, we can assist with both new construction and existing properties.
