Services
Geothermal Installation
Our geothermal installation service creates energy-efficient heating and cooling systems by leveraging underground thermal energy. We drill 200-400 foot boreholes with specialized equipment, install U-shaped loops, and connect systems to heat pumps. Clients benefit from 80% energy savings compared to fossil fuels while maintaining property aesthetics with hidden outdoor units.
Loop Field Drilling
Specialized vertical loop drilling services create durable geothermal infrastructure. Using compact equipment, we access tight spaces and drill precise boreholes for loop installation. Each system includes pressure-tested HDPE piping with 50-year warranties, ensuring long-term thermal conductivity and minimal maintenance requirements for residential and commercial properties.
Heat Pump Setup
Professional heat pump installation connects geothermal loops to building climate control systems. Our team coordinates with HVAC contractors to ensure proper system sizing and integration. The process includes piping fusion, system pressurization, and performance testing to deliver 400% efficient heating and cooling solutions that eliminate carbon monoxide risks.
System Retrofitting
Retrofitting services convert existing buildings to geothermal energy systems. We assess structural specifications to design customized retrofits that improve energy efficiency. Projects include removing conventional HVAC equipment, installing underground loops, and integrating new heat pumps while maintaining building integrity and minimizing disruption.
Energy Analysis
Comprehensive energy analysis determines optimal geothermal system specifications. We evaluate building square footage, insulation levels, and window efficiency to calculate heating/cooling loads. This data drives customized system designs that maximize energy savings while aligning with client budgetary requirements and sustainability goals.
