Services
Geothermal Installations
We design and install complete geothermal heating and cooling systems using ground source heat pump technology. Our installations utilize underground loop fields to transfer heat between buildings and the earth, providing 3-4 units of heating/cooling for every unit of electricity consumed. Systems qualify for 30% federal tax credits and utility rebates.
Radiant Floor Heating
Our hydronic radiant floor heating systems circulate warm water through tubing embedded in floors. This provides even, comfortable heating without air ducts. Combines with geothermal systems for maximum energy efficiency in residential and commercial spaces.
HVAC Repairs
We service all makes and models of heat pumps and HVAC equipment. Our technicians provide emergency repairs, seasonal maintenance, and system diagnostics. Preventative maintenance extends equipment lifespan and maintains optimal efficiency for geothermal and conventional systems.

Questions
Do geothermal systems work effectively in Minnesota's climate?
Yes, Minnesota's climate with distinct seasons makes geothermal systems particularly effective. The ground maintains stable temperatures year-round, allowing efficient heat exchange for both heating and cooling.
What are the cost benefits of geothermal systems?
Geothermal systems can reduce heating and cooling costs by up to 80% compared to conventional systems. Federal tax credits and utility rebates further improve return on investment.
How long do geothermal systems last?
Indoor components last 20-30 years while underground loop fields have a 300-year lifespan. This makes geothermal a one-time infrastructure investment for most homeowners.
What installation options exist for geothermal loops?
We offer horizontal trench, horizontal bore, vertical bore, and pond/lake loop configurations. System design considers soil conditions, available space, and property characteristics.
Do you provide emergency HVAC services?
Yes, we offer 24/7 emergency service for critical heating and cooling needs with rapid response times across our service area.
