Residential Geothermal Loop Systems
Overview of Steps for Residential Geothermal Exterior Installations
At Geothermal Solutions, we focus on the exterior portion of geothermal system installations. The timeline for our portion of the installation depends on the type of loop system, complexity and site restrictions.
Initial Steps for Installation
01
Site Assessment and Planning
Our team assesses your property’s site conditions (soil type, land area, and accessibility) to create the best loop system.
02
Estimate Creation and Approval
After the site assessment, we prepare a detailed estimate for the exterior work, including the system type, timeline, and pricing.
03
Deposit and Agreement
After approval of the estimate, a deposit is required to secure the project, and a signed agreement ensures both parties are aligned on scope and pricing.
04
Locates Completed
Locates are required to mark any underground utilities or services before starting excavation or drilling.
05
Equipment and Material Preparation
While waiting for the locates, we prepare the necessary equipment and materials for the installation, including drilling rigs, trenching tools, and loop system components.
Loop System Installation
1. Drill Rigs are set up to drill and grout vertical boreholes.
2. Boreholes are left capped for tie in crew to bring to the building.
3. Trenches are dug for lateral tie in to connect the boreholes to the building.
4. Geothermal lines are run with tracer wire for future detection.
5. Tie in lines are brought to the building capped and ready for HVAC contractor.
Vertical Loop System
We drill boreholes and install loop piping vertically. The timeline depends on the number of boreholes and soil conditions. After the loop system is in place, we connect it to the building’s system via lateral tie-ins for integration with the HVAC system.
1. Horizontal trenches are dug.
2. Trenches are carved out for pipe.
3. Pipe is laid out in trenches. Once complete the lines are cleared of any debris.
4. Trenches are covered with insulation. Tracer wire and geothermal tape are used for future detection.
5. Lines are brought to the house and capped for future use with HVAC contractor.
6. Trenches are backfilled.
Horizontal Loop System
We excavate trenches and lay the loop piping horizontally across the property.
1. Coils of pipe are assembled and brought out to the body of water.
2. A boat guides the coils of pipe out and a diver sinks the loops with weights.
3. Trenches are dug from the shore to the home and pipe is placed in the trenches.
4. Tie in lines are brought to the building capped and ready for HVAC contractor.
Pond/Lake Loop System
We install loop systems in a nearby pond or lake, utilizing water’s high thermal conductivity for efficient heat transfer.
Final Steps For Installation
Pressure Testing and System Check
We perform pressure tests and system checks to ensure everything is functioning as it should, and there are no leaks.
Handover to HVAC Team
Once the exterior installation is complete, we hand over the system to the HVAC team for the interior installation and full system integration.
Maintenance and Upkeep for Residential Geothermal System Loops
The exterior portion of a geothermal system loop is designed for durability and long-term performance, requiring minimal maintenance. However, periodic upkeep ensures optimal efficiency and system longevity:
Visual Inspections:
Regular checks for signs of ground settling, exposed piping, or leaks help maintain
system integrity.
Pressure Testing:
Annual or bi-annual pressure checks help identify potential issues and ensure the loop remains sealed and functioning properly.
Loop Fluid Maintenance:
Monitoring and replenishing antifreeze or heat transfer fluids when necessary ensures reliable operation in all climates.
By addressing these simple maintenance steps, homeowners and businesses can maximize the performance and lifespan of their geothermal systems while enjoying consistent, sustainable energy.

Residential FAQs
Will I need to do anything to prepare my property for installation?
For horizontal systems, you’ll need enough space for trenches. For vertical systems, we require space for drilling equipment. In all cases, we’ll conduct a site assessment to determine the best placement.
How much land do I need for a horizontal geothermal system?
Horizontal systems require sufficient land area, typically around 2+ acres, but the exact amount depends on your heating and cooling requirements. Our team will assess your property to determine the best approach.
Can I install a geothermal system myself?
Geothermal system installation requires specialized knowledge and equipment, especially for drilling, trenching, and system integration. It’s best to work with a professional geothermal installer like us.
How much maintenance does a geothermal system require?
Geothermal systems generally require minimal maintenance, such as regular checks on the outdoor loop system for damage and occasional system flushing to maintain efficiency.
Are there incentives or rebates for installing a geothermal system?
Yes, the government releases various incentives, grants, and rebates and they may be available depending on your location. Check your local, provincial and federal sites to verify.
