Yoko Higa
Owner and system designer
Does the heat-loss numbers and writes every proposal, ground and air. Starts every job from the bills, not from the equipment.
We are a small firm that does one kind of work.
Six Mile Ground Energy is eight people who design, install and service ground-source heat pumps. We drill with a partner and do everything else ourselves. We would rather lose a job to air-source than sell a loop that does not suit the house.
Who you will meet
Dena Hunt
Field lead
Connects, flushes and pressure-tests the loop, then runs the inside install.
Anjum Trivedi
Controls and commissioning
Sets the pumps, flows and thermostats, and returns after the first month.
Randolph Norton
Site and loop-field coordinator
Marks the bores, schedules the drilling partner and checks the restoration.
