Generac load testing done right, here in Rockland County
If a load test exposes a generator that sags, surges, or won't hold frequency, our Generator Repair team can diagnose the weak component the same week — long before you'd ever discover it the hard way, an hour into an outage with the whole house demanding power.
- A graduated load applied up to your unit's full rated kilowatts
- Output kW against the nameplate, voltage stability, and a steady 60 Hz
- Transfer-switch timing checked from utility to generator and back
- Wet-stacking burned off on units that only ever idle through self-tests
Why Rockland County trusts our load testing
Many homes across Rockland County go years between real outages, so their generators only ever idle through the weekly exercise — which is exactly the pattern that hides a unit's inability to carry a full load until the night it finally has to.
Proven full-capacity output
We confirm your generator actually produces its rated kilowatts under real load — not just that it starts and idles on its weekly test.
Verifies transfer-switch timing
We measure how fast the transfer switch moves your home from utility to generator and back, so the handoff is quick and clean when it counts.
Confidence for storm season
Going into a nor'easter knowing your unit holds voltage and frequency at full load is the difference between hoping and knowing.
Catches wet-stacking & weak output
Units that rarely run a real outage develop fouling and hidden weakness — a load test surfaces both before they cause a failure.
What's included in your Generac load testing
A complete, no-surprises scope — from the first measurement to the final load test.
Capacity test
- Graduated load applied to rated kW
- Output kW measured against nameplate
- Sustained full-load run
- Wet-stacking burn-off if present
Power-quality check
- Voltage stability under load
- Frequency held at 60 Hz
- Under/over-voltage check
- Output waveform observation
Transfer & timing
- ATS transfer-time measurement
- Return-to-utility timing
- Load-step response
- Exercise-cycle reset
Quoted separately if needed
- Repairs for any weakness found (diagnosed, then quoted)
- Scheduled oil, battery, or filter changes — that's routine upkeep, not capacity testing
- Commercial-scale load-bank rental (quoted separately)
Your Generac load testing, step by step
A clear, no-surprises process — here's exactly what to expect, from start to finish.
Connect the Load Bank
We attach a portable load bank so we can apply real, measured electrical load to your generator.
Ramp to Full Load
We step the load up to the unit's rated kW and hold it, watching output the whole way.
Measure Power Quality
We verify voltage stability, 60 Hz frequency, and how fast the transfer switch reacts.
Report & Reset
We give you the numbers against the nameplate, flag any weakness, and reset the exercise cycle.

Frequently asked Load Testing questions in Rockland County, answered
The weekly exercise runs the engine at little or no load, so it only proves the unit starts and idles. It can't tell you whether the generator carries your whole house at full demand. A load test is the only way to verify real capacity.
An inspection is a visual, no-load checkup that finds faults. Load testing applies an actual electrical load to prove the generator delivers its rated power. One looks the unit over; the other makes it work.
We connect a portable load bank, step the load up to your unit's rated kilowatts, and hold it while we measure output, voltage stability, frequency, and transfer-switch timing — a real-world stand-in for your whole house running at once.
At commissioning, after any major repair, and periodically for homes that rarely lose power or run medical equipment. If your unit almost never sees a real outage, a periodic load test is the only thing proving it still performs.
Wet-stacking is unburned-fuel fouling that builds up when a generator only ever idles at low load. It reduces performance over time. A load test runs the unit hard enough to burn it off and confirm clean, full output.
