Does H&N Electric only handle accounts located nearby?

We are ready and willing to go anywhere needed to service our customers. As part of Timken Power Systems (TPS), we share resources with a network of 10 locations to provide gear, motor, controls, switchgear, and bearing expertise across the United States.

Is the H&N Electric shop ISO-certified?

Yes; our products adhere to a Quality Management System that is fully compliant with ASQ/ANSI/ISO 9001 standards, providing consistently high levels of service.

Can H&N Electric work at my location?

Yes. Our specialty mechanical and electrical field services teams can remove and reinstall most rotating equipment, often including “in-place” overhauls at customer locations.

Does H&N Electric offer emergency response?

Absolutely. We pride ourselves on quick turnaround jobs where the cost of downtime is high. We know the pressure you’re under to get back online, and we work until you are up and running.

Is H&N Electric’s work covered by warranty?

The short answer is yes. Our warranties range from one to five years, based on what’s being repaired — and is included at no extra charge.

Whether you need service on switchgear, controls, electric motors, generators, bearings or gearboxes, Timken Power Systems’ locations offer a warranty that often meets or exceeds that offered by the OEM.

Do you provide on-site (up-tower) wind turbine services, and what can you do up-tower?

Yes. Our certified up-tower technicians perform services including gearbox and generator repairs, bearing replacement, brush and wye-ring service, advanced oil changes, inspections, and large correctives. We use specialized tooling and safety-certified crews to minimize downtime and restore turbine availability.

We validate repairs with industry-standard testing before equipment returns to service.

Do you offer preventative maintenance programs and condition monitoring?

Yes. We design custom preventive maintenance (PM) programs and offer condition monitoring services including vibration analysis, oil analysis, infrared thermography, and periodic inspections to identify issues early and extend mean time between failures.

What are “large correctives” in regards to wind turbine repairs?

Large correctives are major repair and restoration projects performed to fix significant drivetrain or structural failures on a wind turbine that routine maintenance cannot resolve. These are comprehensive interventions aimed at returning turbines to safe, reliable operation and addressing root causes to prevent recurrence.

Can upgrades be performed during a large corrective?

Yes. Large correctives are an ideal opportunity to implement durability and reliability upgrades — upgraded bearings, improved seals and lube systems, condition-monitoring sensors, and retrofits that address the root cause of failures and reduce future downtime.
