Generator Maintenance Procedure Recommended by Manufacturers

If you your standby generator is not running properly, or not running at all, you need to act right away. These units should not stay idle too long. Insects, rodents, and other animals will soon go inside your generator and cause additional damage as they make a home of it. This will undoubtedly cost hundreds of additional dollar to repair.

We are experts in terms of generator service, generator repair, generator troubleshooting, and generator diagnosis. We follow manufacturer's standard procedures to tune and calibrate your generator to their specifications.

We will make sure that when we are done, your unit is running according to manufacturer's recommendations.

Even if your machine appears to be running fine, if you have not done proper scheduled maintenance, it may be needing a tune-up and other adjustments right now.

Generator Enclosure Repair or Replacement. Make Your Generator Like New Again

In coastal areas, where generators are exposed to humid salty air, their enclosures tend to wear out fast due to corrosion. Often the generator and engine are in good condition, but rust has destroyed most of the enclosure, chassis, and base.

In these kinds of circumstances we recommend that you replace the enclosure rather than discard the entire generator. This is normally a costly repair, but it certainly cost less than replacing the entire generator set.

If the corrosion has not done extensive damage to the enclosure and chassis, we may recommend to have them repainted. We have a painting program in which your generator is treated in such a way that it can be restored to a very acceptable condition and afford you many years of service.
