Jordan, Brayden, and Kaleb just wrapped up the job at my place and I could not be more pleased. They were professional, kind, and went above and beyond. My wife and I are building a house in Bulls Gap, and needed to hook up a pressure pump. I didn't realize what all would be needed, but they nailed it. They installed a pressure tank under the house and finished all of the piping and fittings. Because we don't have electric for our pump house, they got my generator running and made sure everything worked as it should. I won't use anybody else going forward. Thank you, guys! Y'all are awesome!

  2. Routine Operational Testing
  3. Corrective Repair Work
  4. Performance Optimization
  5. Compliance Verification and Reporting

Each stage is designed to ensure generators deliver immediate, reliable power during utility interruptions.

HEP’s Generator Expertise: From Standby to Prime Power

Standby Generators

Designed to activate automatically within seconds of a grid failure, standby units are popular with homeowners, medical clinics, and small businesses across Erwin. HEP technicians verify:

  • Automatic Transfer Switch (ATS) responsiveness
  • Battery integrity
  • Fuel system cleanliness
  • Proper exhaust clearance
  • Load acceptance under both cold-start and warm-start scenarios

Prime Power Generators

Agricultural operations, remote construction sites, and certain industrial facilities often depend on generators as their primary power source. HEP’s service plans for prime power units include:

  • Continuous runtime oil sampling
  • 24/7 remote monitoring integrations
  • Exhaust gas temperature balancing
