Services
Geothermal System Design
Our AEE Certified GeoExchange Designer creates customized ground source heat pump systems using advanced cold climate engineering principles. We analyze site geology, heating requirements, and property constraints to develop efficient loop configurations that maximize energy extraction. Every design incorporates 30-year performance projections and cost recovery analysis.
Residential Installations
We specialize in complete geothermal heating and cooling solutions for single-family homes, including radiant floor integration and forced-air hybrid systems. Our installations utilize ColdClimate technology to ensure 100% geothermal heating even during Minnesota's extreme winters. All systems include energy savings guarantees and performance warranties.
Commercial Systems
Our team designs and implements large-scale geothermal systems for commercial buildings, including schools, community centers, and office complexes. We coordinate with architects and engineers to integrate high-capacity vertical bore fields and hydronic distribution systems that meet ASHRAE standards while minimizing operational costs.
Pond Loop Design
We engineer closed-loop geothermal systems utilizing existing water bodies to enhance heat exchange efficiency. Our patented installation methods allow pond systems to operate effectively even under 8 inches of ice, providing consistent heating performance throughout northern winters while maintaining environmental integrity.
Vertical Bore Fields
Our vertical ground heat exchanger installations use precision drilling techniques to create compact systems in rocky terrain. Partnering with specialized drilling contractors, we implement borehole spacing correction factors and advanced grouting formulas to optimize thermal conductivity in Lake Superior bedrock formations.

Questions
What makes geothermal systems suitable for cold climates?
Our ColdClimate™ systems use specialized heat pumps and advanced loop designs that maintain efficiency at ground temperatures as low as 25°F, achieving 96-100% heating performance even during Minnesota's extreme winters.
How long do geothermal installations last?
Properly installed systems last 25+ years for heat pumps and 50+ years for underground loops. Our installations include durable HDPE piping with 10-year warranties and maintenance contracts for ongoing performance optimization.
Can geothermal work with existing heating systems?
Yes, we design hybrid systems that integrate geothermal with existing infrastructure. Our engineers assess your current setup to determine the most cost-effective transition to geothermal heating and cooling.
What rebates or tax credits are available?
Current 30% Federal Tax Credits apply to qualified installations. We help clients navigate local utility rebates and financing options to maximize return on investment through energy savings programs.
How much space do geothermal loops require?
We design systems to fit your property using vertical bore fields, horizontal trenches, or pond loops. Our engineers optimize loop density to minimize land use while maintaining system efficiency in northern climates.
What maintenance do geothermal systems need?
Annual inspections and filter changes are recommended. Our NATE-certified technicians provide preventive maintenance contracts to ensure optimal performance and extend system lifespan through proper fluid checks and component testing.
