Dillan Well Drilling provides turnkey geothermal loopfield installation for homeowners, home builders, and HVAC contractors throughout Western Pennsylvania and Eastern Ohio. With more than 500 residential geothermal loopfields installed, our team has the drilling experience and technical knowledge needed to support efficient ground-source heating and cooling systems. From new construction to geothermal upgrades for existing homes, we coordinate with your HVAC contractor and project team to install the underground loop system based on the property's conditions and system requirements. Our goal is a properly installed loopfield built for reliable heat transfer and long-term performance.
Commercial geothermal projects require experienced crews, specialized equipment, and careful coordination. Dillan Well Drilling provides geothermal drilling and loopfield installation for projects ranging from approximately 3 tons to 500 tons, supporting systems for commercial and institutional properties. We work with architects, engineers, general contractors, and HVAC contractors to keep complex geothermal projects moving forward. With multiple drill rigs and experienced installation crews, Dillan Well Drilling has the capabilities to support demanding project schedules and large-scale loopfield installations.
Vertical geothermal loopfields use drilled boreholes to install underground piping deep below the surface. This approach can be an effective solution for properties with limited available land or projects where site conditions favor a vertical loop design. Our experienced drilling crews install geothermal boreholes with attention to proper depth, spacing, loop placement, and grouting. Boreholes are properly grouted to support efficient heat transfer while helping protect underground aquifers.
When adequate land is available, a horizontal geothermal loopfield may provide an efficient option for a ground-source heating and cooling system. Geothermal piping is installed in excavated trenches and configured according to the system design and property's heating and cooling requirements. Dillan Well Drilling helps coordinate horizontal loopfield installations for residential and commercial projects, working with project partners to deliver a dependable underground system designed for long-term geothermal performance.
Properties with a suitable pond or body of water may be candidates for a pond loop geothermal system. In the right conditions, submerged geothermal loops can use the stable temperature of the water to support efficient heat exchange. Our team can help evaluate project requirements and install pond loop systems designed around the geothermal system plan. We work closely with HVAC professionals and project teams to ensure the underground and submerged loop components are properly installed.
For larger geothermal projects, understanding how efficiently the ground transfers heat is an important part of loopfield planning and system design. Dillan Well Drilling provides thermal conductivity testing to support engineers and geothermal system designers with site-specific subsurface data. Accurate testing can help project teams evaluate borehole and loopfield requirements, improve system planning, and make informed decisions before full-scale geothermal drilling begins.
From drilling and loop placement to heat fusion, grouting, and pressure testing, Dillan Well Drilling provides turnkey geothermal loopfield installation services. Our IGSHPA-certified crews and heat fusion certified technicians bring specialized training and field experience to each project. Whether you are planning a residential ground-source heat pump system or a large commercial geothermal project, our team can handle the underground loopfield work and coordinate with your HVAC contractor, engineer, builder, or general contractor from start to finish.
Geothermal heating and cooling is one of the most efficient and environmentally friendly ways to maintain year-round comfort for your home or business. By harnessing the consistent temperature below the earth's surface, geothermal systems provide reliable heating in the winter and cooling in the summer while using significantly less energy than traditional HVAC systems.
Whether you're constructing a new home, upgrading an existing property, or planning a commercial development, a professionally installed geothermal loopfield can deliver long-term energy savings, lower utility costs, and dependable performance for decades.
At Dillan Well Drilling, we understand that every property is unique. Our experienced team works closely with homeowners, builders, HVAC contractors, engineers, and developers to design and install geothermal loopfields that match your property's size, soil conditions, and heating and cooling demands.
Every geothermal project starts with understanding the property and the heating and cooling requirements of the system. Our team reviews site access, available land, drilling conditions, and the proposed geothermal design while coordinating with homeowners, builders, HVAC contractors, engineers, and other project partners. From new construction to geothermal upgrades for existing homes, we coordinate with your HVAC contractor and project team to install the underground loop system based on the property's conditions and system requirements. Our goal is a properly installed loopfield built for reliable heat transfer and long-term performance.
Based on the system design and site conditions, the project may use vertical geothermal boreholes, horizontal loops, or a pond loop configuration. Dillan Well Drilling coordinates the underground loopfield work with the project team to help ensure the installation meets the geothermal system's requirements.
Our experienced crews complete the required drilling or loopfield installation using specialized equipment and proven geothermal installation practices. For vertical systems, boreholes are drilled to the required specifications before the geothermal loops are installed.
Our heat fusion certified technicians properly join geothermal piping to create strong, dependable connections throughout the underground loop system. Careful installation at this stage is essential for the long-term integrity and performance of the loopfield.
Vertical geothermal boreholes are properly grouted to support efficient heat transfer and help protect underground aquifers. Our crews follow established geothermal installation practices with attention to borehole integrity and long-term system performance.
Before the loopfield installation is completed, the system is pressure tested and checked for proper integrity. Our team carefully reviews the underground loop system so project partners can move forward with confidence.
Dillan Well Drilling works closely with HVAC contractors, engineers, builders, architects, and general contractors throughout the project. From residential geothermal installations to large commercial loopfields, our goal is to keep the underground portion of the geothermal system organized, efficient, and on schedule.

Geothermal heating and cooling uses the stable temperature below the earth's surface to help heat and cool a building. A ground-source heat pump works with an underground geothermal loopfield to transfer heat between the building and the ground, providing efficient year-round indoor comfort.
A geothermal loopfield consists of underground piping that circulates fluid and exchanges heat with the surrounding ground. During colder months, the geothermal system draws heat from the ground. During warmer months, it transfers heat from the building back into the ground.
Vertical geothermal systems use boreholes drilled deep into the ground and are often well suited for properties with limited available land. Horizontal geothermal loopfields use piping installed in excavated trenches and typically require more open space. The right configuration depends on the property, site conditions, and geothermal system design.
