Geothermal HVAC Experts in St. George, UT | Nu Tech Heating & Cooling

A DX system is a specific type of geothermal heating and cooling that uses copper refrigerant lines buried directly in the ground. Unlike other geothermal systems that use a water-based loop and a separate pump, the refrigerant in a DX system circulates directly, exchanging heat with the earth. This design often results in higher efficiency, fewer mechanical components, and potentially lower maintenance needs for your St. George home.

Yes, it can significantly reduce that risk. In St. George, air handler fans often fail due to the extreme strain of constantly running a standard AC unit in our heat. A geothermal system works much more efficiently, with the ground's stable temperature doing most of the work. This means the indoor air handler runs less frequently and under less stress, leading to less wear and tear and a longer lifespan for that component.

We provide solutions for both. While integrating geothermal into a new build during construction is straightforward, we have extensive experience retrofitting existing homes in St. George and the surrounding region. Our team will assess your property's layout and soil conditions to design a Direct Exchange system that works efficiently with your current home's footprint and ductwork.
