Our process

  1. 1. Load calculation
    We perform a NEC load calc and recommend the right service size.
  2. 2. Permit & utility coordination
    We pull the permit and schedule the utility disconnect/reconnect.
  3. 3. Single-day install
    Most panel upgrades are completed in one day with the home re-energized by evening.
  4. 4. Inspection & closeout
    We meet the inspector, close the permit, and email you the closed permit copy.
