Larson Well Co. drills vertical geothermal loop fields for efficient, long-lasting geothermal heating and cooling — for homes, farms, and commercial buildings across Iowa.
Geothermal heating and cooling relies on stable underground temperatures to move heat efficiently — but only if the loop field is drilled correctly. Larson Well Co. brings the same precision we apply to water well drilling to every geothermal loop project, ensuring proper depth, spacing, and grouting for maximum system efficiency.
We work alongside HVAC contractors and homeowners to drill vertical closed-loop fields sized to your building’s heating and cooling load, using equipment built for Iowa’s soil and rock conditions.
Geothermal systems installed with a properly drilled loop field can significantly reduce energy costs compared to traditional furnaces and air conditioners, while lasting decades longer than conventional HVAC equipment.
GEOTHERMAL DRILLING AT A GLANCE
Vertical loop fields sized for single-family homes, cutting heating and cooling costs year-round.
Larger loop fields engineered for offices, schools, and commercial buildings with higher heating and cooling demand.
Geothermal loop drilling for new builds as well as retrofits replacing aging furnace and AC systems.
WHY GEOTHERMAL
We start with a site evaluation to determine loop configuration and drilling depth, then drill and grout each borehole to spec before connecting the loop field to your HVAC contractor’s system. Every project is permitted and tested before we leave the site.

Common Questions
Geothermal systems use stable underground temperatures to heat and cool buildings far more efficiently than traditional furnaces and air conditioners, often reducing energy costs significantly over the life of the system.
Cost depends on the size of your loop field, drilling depth, and number of boreholes needed for your building’s heat load. Larson Well Co. provides a free estimate based on an on-site evaluation.
Depth depends on soil composition, available yard space, and your system’s heating and cooling load, which is why a site evaluation is essential before drilling begins.
A properly drilled and grouted geothermal loop field can last 50 years or more, significantly outlasting the HVAC equipment connected to it.
Yes, geothermal loop drilling typically requires permitting, which Larson Well Co. manages as part of every project.
Vertical loop drilling has a relatively small footprint compared to horizontal loop systems, and we restore the drilling area once boreholes are grouted and connected.
In many cases, yes. We coordinate directly with your HVAC contractor to ensure the loop field matches your system’s requirements.
