Without proper maintenance, backup generators can be prone to erratic reliability and unexpected failure.

The best approach to safeguard your generator and ensure it will perform when you need it most is to engage in routine preventive maintenance.

Unified Power’s Generator Service provides expertly trained technicians who can identify and resolve issues before they turn into expensive problems.

Proactively Detect Issues

Because many generators do not display symptoms of impending failure, it is essential to detect issues as early as possible ── not when there is a power outage and your unit fails to kick on. Generators that are not maintained are also more likely to produce carbon monoxide, which can be fatal if inhaled.

Optimize Ongoing Generator Performance & Safety

During maintenance, all generator parts are checked, cleaned and tested to ensure they are functioning as intended, bolstering overall efficiency.

Technicians also look for evidence of animal activity since mice, rats, wasps, birds and snakes are notorious for infesting a generator’s housing or chewing through the wiring.

Fuel levels are measured and the diesel supply is changed.

Save money On Generator Maintenance and Repairs

Properly maintaining your generator ensures that it will run smoother for a longer period of time, reducing the risk of costly downtime and lowering overall total cost of ownership.

Research shows that unmaintained generators typically have shorter lifespans, so an ounce of prevention goes a long way when it comes to preventive maintenance.
