About this Service
Centennial suburban homes and planned developments often need Geothermal Heat Pump replacement when older systems degrade or when owners want improved efficiency. The service removes the existing unit, reviews ground-loop feasibility in Denver basin clays and sand lens layers, and installs a new ground-source unit sized for balanced seasonal loads. The emphasis is on matching loop design to local subsurface variability.
Denver basin clays and intermittent sand lenses affect trench stability and bore integrity. Sand lenses can create unstable bore walls and change thermal conductivity locally. In many Centennial yards, a mixed approach — horizontal arrays where stable clay dominates and vertical bores where sand lenses interrupt continuity — yields the best performance. Site evaluation typically includes probe borings and a thermal-response test before deciding on loop reuse. Expect the recommendation to balance excavation impact against drilling costs.
A full replacement package includes refrigerant recovery, old-equipment disposal, new unit installation, loop remediation if required, and commissioning tests to document performance. Itemized estimates should call out potential sand-lens remediation, additional grout or casing, and timing constraints related to hot afternoons that affect final load tests. Post-install commissioning measures system COP and supply/return differentials to confirm the system meets design expectations.
