What our customers say

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!

I know that every business has employees but, I want to extend well deserved "Thank You" to Richard W. My home had no heat and, half of my home power was out due to my unit burning a hole in the connections. Richard showed up within an hour once he read my home had no heat. I could have shopped around for quotes but, Richard W answered all my questions and made me feel comfortable, especially when explaining in detail the pricing breakdown. "Thank You" Richard W again, you are the reason I completed this transaction and, I appreciate all the added care you provided to me today in my time of need.

Infrared Thermography

Identify hot spots on alternator windings, breaker lugs, and exhaust manifolds, revealing loose connections or impending insulation failure.

Oil Spectrometry

Analyze trace metals such as iron, chromium, and sodium, signaling wear of rings, bearings, or head gaskets long before catastrophic symptoms surface.

Power Quality Analyzers

Capture harmonic distortion, voltage sags, and transients to ensure the generator’s output will not compromise sensitive electronics downstream.

Environmental Responsibility in Generator Service

Proper generator care includes safeguarding Shelbyville’s natural resources:

Spill Prevention

Technicians deploy absorbent mats and drip pans before servicing fuel and oil circuits. Transfer pumps equipped with automatic shut-off valves prevent overfilling.

Waste Oil Recycling

All drained lubricants are sealed in DOT-approved containers and transported to certified recyclers. Used filters undergo hot draining to minimize residual fluids.

Emission Control Checks

After each service, exhaust opacity readings confirm compliance with state air-quality thresholds. If results deviate, injector timing, air-filter integrity, and turbo performance are adjusted accordingly.

Shelbyville-Specific Considerations

Local Climate Challenges

The region experiences humidity exceeding 80 % in midsummer and wind chills below 10 °F in winter. HEP tailors coolant blends, battery CCA ratings, and lubrication viscosity to these extremes.

Grid Infrastructure Particularities

Shelbyville’s mix of underground and overhead distribution lines leads to outages from both vehicular accidents and tree-limb strikes. Generators often engage multiple times per year, making high-hour maintenance schedules essential.

Community Preparedness Initiatives

Municipal guidelines encourage facilities such as nursing homes and public schools to conduct bi-annual generator drills. HEP coordinates testing to align with these community mandates, ensuring readiness without interrupting daily operations.

Why Qualified Service Is Critical for Standby Generators

Safety Assurance

Improperly torqued fuel fittings or incorrect phase rotation can spark fires or damage connected loads. Certified technicians follow lockout/tagout protocols and adhere to manufacturer torque charts.

Warranty Preservation

Engine and alternator warranties often stipulate professional service at defined intervals. Skipping visits or using non-OEM components can nullify coverage, turning future failures into out-of-pocket expenses.

  • ATS fails to transfer load within the standard 10-second window
  • Alarms for high coolant temp, low oil pressure, or undervoltage repeating after resets
  • Fuel consumption rates rising despite unchanged load levels
  • Visible leaks or puddles beneath the unit

Early intervention preserves components and averts unplanned outages.

Generator Service Scheduling Best Practices

Seasonal Planning

  • Conduct major inspections in spring and fall, preparing for peak storm seasons.
  • Swap air filters and adjust coolant ratios before Shelbyville’s temperature extremes hit.

Runtime-Based Intervals

  • Light-duty residential sets may suffice with semi-annual maintenance plus monthly exercise.
  • Commercial generators exceeding 300 hours per year benefit from quarterly visits, with additional oil changes every 150 hours.

Logbook Discipline

  • Record exercise runtimes, alarm resets, and environmental conditions.
  • Note fuel deliveries, filtrate levels, and any manual overrides.
  • Share digital logs with HEP to refine maintenance strategies based on real-world usage patterns.
